. C-1 Chapter 1 Introduction Product Overview Malibu Networks 240/2400 AirMAX fixed wireless broadband access in the 2.4GHz ISM band with an impressive array of features ideal for voice, video and data communications. system provides TM AirMAX uniquely takes bi-directional IP traffic and offers quality of service (QoS) features ideal for Internet Service Providers and corporate facility implementations. The system is composed of a BTS, CPE, a full featured optional Service Management System (SMS) and Malibu s patent pending MAXimum IP QoS. TM The CPE and BTS portions of the system are all outdoor units (ODU) ruggedized for the harshest environments with an operating temperature range of up to 70 Reliability and cost effectiveness were key design goals for this system. By utilizing many standard off-the-shelf components, AirMAX is mature, reliable, and takes advantage of volume production resulting in the best performance and value available today. C. o 2 Malibu Networks AirMAX CPE/BTS Chapter 1: Introduction System Components AirMAX system components are:

Base Transceiver Station (BTS): transmits to and from one or more customer premises (CPE) systems. Customer Premises Equipment (CPE): transmits from a local customer site to and from a BTS system. Both CPE and BTS systems are functionally Note:

similar in that they are made up of an antenna, controller card, radio modem and power supply (items contained in the ODU and Power Injector units). When we discuss a BTS or CPE system therefore, remember that it consists of an ODU and a Power Injector. Ethernet Power Antenna Power Injector ODU Figure 1-1. Basic System, CPE or BTS ODU: Outdoor Unit and antenna. The ODU is a ruggedized box, often antenna-mast mounted, that houses a radio modem and connects to an antenna. It has a special Power-over-Ethernet (PoE) cable that passes both data and power to/from the Power Injector. The radio modem and circuit board inside have non-volatile memory and a standalone CPU that communicates with other systems. Remote management software configures and controls the ODU. Power Injector: This unit is placed inside the customer s facility and connects the site s 10/

100Base-T LAN to the ODU. It also functions as an AC adapter that passes power to the ODU along with data over the PoE ethernet cable. Installation and Configuration Product Overview 3 The Power Injector has two parts, an AC adapter power module that plugs into a 110/220VAC source and a small module (called the power injector) that has the two RJ-45 ethernet connections (LAN and ODU) and connects to the power module. PoE Cable ODU Router Power Injector WAN BTS To build an AirMAX system, you need a BTS and one or more CPE systems as needed for subscribers.

Flow-through provisioning configuration and deployment by any authorized entity. for rapid service 4 Malibu Networks AirMAX CPE/BTS Chapter 1: Introduction SMS As the system Southbound SNMP interface is fully compliant with SNMP v2 using the Malibu enterprise MIB and the standard MIB II object library. Distributed management technology:

grows from a few base stations to as many as hundreds of base stations, expensive, high-

performance, single-point-of-failure servers can be avoided by distributing SMS functions over a number of low-cost servers SLA (service level agreement) facilitation:

offers complete flexibility in service definition, provisioning, and monitoring. In addition, tools are provided to empower the service provider to customize SLAs to meet unique subscriber needs, and to meet the requirements of the operator s specific business model. Jitter and latency are all configurable characteristics of each Service Definition Suite. These definitions can be applied on a per-flow basis. Intelligent provisioning:

efficiently accomplished with constant monitoring of current service level agreements and available system resources, preventing unwanted over-

subscription of guaranteed services. In this way, new subscribers and their services can be added to the network with the assurance that existing service level agreements will continue to be fully supported. resource management is Installation and Configuration Product Overview 5 a service provider will see an MAXimum IP (QoS):

immediate, dramatic increase in their bottom line due to Malibu s QoS implementation in AirMAX. MAXimum IP accomplishes this through two primary means. First, the efficiency of the system is increased resulting in a subscriber throughput improvement compared to similar systems without MAXimum IP. Second, MAXimum IP offers considerably more than just minimum and maximum bandwidth control per CPE and per subscriber behind the CPE, a claim no other vendor can make today. MAXimum IP also gives the service provider the ability to control jitter and latency as well as enabling additional high value services to be sold and supported.

Before Installation Chapter 2 Installation When preparing to install an AirMAXTM system, first ensure you ve gathered all the information needed:

Analyze environmental and facility requirements and determine antenna, ODU, and Power Injector mounting locations. Ensure locations offer optimum direction for the terrain. Temperature limits at ODU mounting locations should be within this range: -20oC to +70oC Temperatures at Power Injector mounting locations should meet normal office or home conditions. Decide on antenna mounting specifics: do you want to pole or wall-mount the ODU? Locate antenna as high as practical for best coverage. 10 Malibu Networks AirMAX CPE/BTS Chapter 2: Installation CAUTION Ensure antennas between communicating AirMAX systems are within a 12.4 mile range (20Km). You can have up to 100 subscribers per CPE and up to 100 CPEs per sector (with 500 subscribers per sector). Ensure that the overall Ethernet cabling between the ODU, Power Injector, and customer LAN connection

(router/switch/etc.) is less than 300 feet total. If you need a longer distance, you can insert signal conditioning equipment between the Power Injector and customer equipment. The PoE cables supplied by Malibu are from 25 feet to 250 feet in length. Caution: when making actual cable connections at the time of installation, do not confuse the ethernet cable from the customer s LAN to the Power Injector which is data only and does not have power and the PoE Ethernet cable that runs between the ODU and Power Injector which does have power. These connections are made at the Power Injector, which has two RJ45 connectors, and it is possible to plug in the wrong cable and damage equipment. Always check which cable you re plugging in when making Ethernet connections to the Power Injector. The correct Power Injector Ethernet connections are shown later in this Chapter. This manual illustrates the connections as the procedures are given. Ensure the workers installing the ODU and antennas are experienced installation professionals familiar with all local building codes and safety regulations, and who are licensed for the type of work being performed. Installation and Configuration Installation Overview 11 Installation Overview Antenna Antenna Base Antenna Cable Base Assembly After choosing installation locations, you re ready for physical and electrical installation (explained in this chapter). Later in Chapter 3 we explain how to configure the system via web browser. To help give you an overiew, let s summarize the complete installation procedure to install an AirMAX system:

1. First, install the physical BTS system hardware, including ODU, Power Injector, antenna, and cabling. 2. Connect a PC to the Power Injector with a crossover cable or LAN connection, set the IP of the PC to a value compatible with the BTS, and then configure BTS software from a web browser by entering the IP address of the BTS. 3. From the same PC connected to the BTS, add the CPEs you wish to communicate with the BTS. 4. With the BTS now installed and configured, you ll 2 I n s t a l l a t i o n next install the physical CPE system hardware, including ODU, Power Injector, antenna and cabling. 5. Now, just as the BTS was configured, you ll then connect a PC to the CPE s Power Injector, set the IP of the PC to a value compatible with the CPE, and then configure the CPE s radio modem. As on the BTS, you ll enter the default factory IP address of the CPE into the PC browser to connect to it. 6. Finally, you ll test the wireless communication between BTS and CPE using a PC attached to one system (BTS or CPE). Parts Kit Figure 2-1.

(factory preset IP of 192.168.1.1 that you can change after installation) Configuration applies to both CPE & BTS Figure 2-2. Basic Component Overview Now that you have an overview, let s begin the physical installation of CPE and BTS components antenna, ODU and Power Injector units, and cabling through the remainder of this chapter (steps 1 and 4 in our previous overview). In Chapter 3 we ll go through all the detailed steps of configuration. Mounting the BTS or CPE Antenna The antenna supplied for use with ODUs can be omni-

directional or directional. Positioning of BTS omnidirectional antennas is somewhat flexible. However, care should be taken to position it where topography or buildings do not impede transmission. CPE directional antennas require much more care in mounting since they must be directed toward the BTS antenna. Generally you should always plan for a line of sight position between antennas where possible. Mount the antenna as high as possible. Antennas should be clear of obstructions that may affect performance. Ensure that the antenna is mounted so that people will be at least 2 meters away during system operation. Pole mounting of antennas is preferable to wall mounting. If you wall mount the antenna, you must ensure that people on the other side of the wall will remain 2 meters from the antenna when the system is in operation. You may not co-

locate the antenna with other antennas. Omnidirectional Antenna Mounting Mast Installation and Configuration Mounting the BTS or CPE 13 To mount the antenna, follow the relevant steps for omnidirectional or directional antennas on the following pages. 1. Install a customer-supplied mast of 1 to 2 inches in diameter. Position the mast for true vertical using a level. Brace the mast as necessary so that it remains stationary in expected wind conditions. 2. Locate the small 2.5 long antenna base (a threaded tube having two grooves on its outer surface). Also set aside two of the mounting clamps. Figure 2-3. Base to Mast Attachment, Omnidirectional 3. Slide the antenna cable up through the antenna base and then hold it while screwing the antenna into the antenna cable connector. With the cable now attached and fully threaded onto the antenna, screw the antenna base onto the antenna. 4. Place a U-type screw around the antenna base and through the matching screw holes in one of the antenna clamps (on the flat side). On the inside of the clamp, secure the U-type screw with the supplied washers and nuts. 5. Ensure the U-type screw is aligned with one of the grooves on the antenna base circumference. 6. Repeat step 4 with the other U-type screw and clamp. 7. Hold the antenna base and clamps previously assembled next to the antenna mast where you want it positioned. 2 I n s t a l l a t i o n 14 Malibu Networks AirMAX CPE/BTS Chapter 2: Installation CPE Directional Antenna Mounting 8. Then for each of the clamps, place two bolts through the clamp on one side of the mast and then place another clamp over the bolts on the opposite side of the mast. Secure the bolts with the washers and nuts supplied (one each for each bolt). 9. Tighten the nuts securely enough to bite into the mast and prevent slipping, but not overtightened to the point of damaging the mast (particularly on aluminum masts). 10.Repeat this procedure for the other clamps. 1. Install a customer-supplied mast of 1 to 2 inches in diameter. Position the mast for true vertical using a level. Brace the mast as necessary so that it remains stationary in expected wind conditions. 2. Place Antenna Bracket (articulated) on back of directional antenna and secure with the two nuts suppied (see figure). 3. Place U-bolt through the bracket end-plate, around the mast, and through the Antenna bracket. Secure the antenna with two nuts over the threaded ends of the U-bolt. Leave nuts slightly loose so you can adjust the antenna. Installation and Configuration Mounting the BTS or CPE 15 4. Using a compass or GPS unit to judge direction, position the antenna so it is pointed toward the known BTS antenna location. Later in Chapter 3, when you configure the CPE, you ll use signal strength and quality metrics reported by the CPE Status web page to fine tune the antenna s direction.

These RJ45 connectors are identical, and it is possible to plug in the wrong cable and damage equipment. Always check which cable you re plugging in when making Ethernet connections to the Power Injector. The correct Power Injector Ethernet connections are shown in figure 2-6. CAUTION 1. Connect the ODU Ethernet cable carrying power and data to the circular Multipin Ethernet connector on the ODU. At the other end of the same Ethernet cable, plug the RJ45 connector into the Power Injector connector on the side of Power Injector that does not have the power connection. 2. Connect the Ethernet cable from the configuration PC (or the customer s LAN connection) to the RJ45 connector on the Power Injector adjacent to the power connector. Note: If connecting a PC directly to the Power Injector, then you must use a crossover Ethernet cable. If connecting to a LAN, then use a standard Cat5 Ethernet cable. 3. Plug in the AC/DC power adapter cable into the Power Injector power socket. 4. Plug the AC/DC power adapter into an 100-240VAC power source. Note: Appearance and form factor of AC Adapter may differ from that shown in illustration. Installation and Configuration Connecting Ethernet and Power 21 The ODU contains a single board computer (SBC) that controls the QoS and wireless networking operation of the CPE or BTS it s part of. On the SBC is a radio modem, non-volatile memory and the ability to communicate with an external computer over its Ethernet link for remote management. In Chapter 3, Configuration, we ll describe how to configure the AirMAX system using a Windows PC running Windows 98, 2000, or NT; however, you can use any type of computer as long as it has an internet web browser and NIC. 2 I n s t a l l a t i o n 22 Malibu Networks AirMAX CPE/BTS Chapter 2: Installation Chapter 3 Configuration Configuration Overview Once your AirMAXTM BTS and CPE units are physically installed and cabled, they can then be configured remotely from a PC workstation running an internet web browser such as Internet Explorer or Netscape Navigator. The easy-to-use browser interface allows you to set up the TCP/IP addressing of the CPE and BTS system(s), determine system status, configure the wireless radio, and test or reboot the systems. In this chapter we ll go through the steps of configuring a complete system, starting with a BTS unit, then a CPE unit, and then testing the two together as a complete wireless system. As discussed in Chapter 1: Introduction, here are the steps we ll cover:

1. Connecting a PC to the Power Injector with a crossover cable and configuring BTS software from a web browser. 2. From the same PC connected to the BTS, adding CPEs you wish to communicate with the BTS. 24 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration 3. Connecting a PC to the CPE s Power Injector with a crossover cable and configuring the CPE s radio modem. You can also change CPE IP address

(optional). 4. Testing BTS to CPE wireless communications using an attached PC. Initial TCP/IP Configuration All AirMAX systems come factory preset with a default IP address (192.168.1.1) to simplify network configuration. At configuration you then can change the default IP to a customer-provided valid IP on your LAN. Before configuring the AirMAX system, ensure that you know the IP addresses, router IP address (sometimes called gateway IP), and subnet mask that will be used for the AirMAX CPE or BTS system. Your network administrator should be able to provide you with the proper values. Also, ensure that a PC with an internet browser is available that has connectivity to the AirMAX system Power Injector, either via a LAN connection (hub or switch) or by direct connection via an ethernet crossover cable. You will be using this PC to configure the AirMAX BTS and CPE units. PoE Cable ODU Router Power Injector WAN BTS To build an AirMAX system, you need a BTS and one or more CPE systems as needed for subscribers.

Initial TCP/IP Values Worksheet Item Value Needed gateway IP subnet mask IP addresses for CPEs (1 for each if using static IPs this may not be necessary) Configuring the BTS 3 C o n f i g u r a t i o n To configure the BTS, we ll connect a PC to the Power Injector with a crossover cable, set the IP of the PC to match the subnet of the default BTS configuration, and then configure BTS software from a web browser. Follow the detailed steps:

1. Connect a computer with a javascript-ready internet web browser to the Power Injector via an Ethernet crossover cable. Here we discuss using a Windows 98/2000/NT/XP PC, but you could use some other platform such as Linux or MacOS. Power up the PC. (Chapter 2 provides photos and details on physical installation.) 2. Enter the Network Control Panel (Settings/Control Panels/Network) on the Windows PC, select the Configuration Tab and TCP/IP definition screen and then set the IP address of the PC to 26 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration 192.168.1.2. Set the Subnet Mask to 255.255.255.0. This will put the PC on the same subnet as the default BTS TCP/IP configuration. Launch a Web Browser on the PC Figure 3-2. TCP/IP Settings on PC (Windows) 3. Restart the PC if the OS requires it (Windows 98 does). Your AirMAX BTS and CPE units are configured using a web browser running on a Windows PC or other workstation. The configuration web pages are entered by simply entering the IP address of the AirMAX BTS or CPE you wish to configure. This action launches a webserver built into the CPE or BTS and provides you with several web pages of information you can view and configure. Installation and Configuration Configuring the BTS 27 Follow these steps to access the BTS:

1. Launch Internet Explorer or Netscape Navigator on the PC. 2. Enter http://192.168.1.1 in the web browser s URL or Location field:

http://192.168.1.1 Figure 3-3. Enter BTS IP address in Browser URL field After entering the IP address of the BTS, the browser should display a logon screen; enter malibu as the user (no password is initially required however you can add one as discussed later in this Chapter):

3 C o n f i g u r a t i o n After you logon, you ll see an initial Status screen. From the Status screen, you can get to these additional screens as follows:

Configure this page is where you ll configure the BTS TCP/IP settings and CPE/BTS radio modem. 28 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Test this page provides buttons to start continuous radio transmission, start continuous Ethernet data transmission, and stop both Ethernet and radio transmission. These functions are intended only for testing purposes. They should always be turned off for normal operation since they will block wireless LAN traffic. Statistics this page shows data flow characteristics. Management Pages (Service Levels, Subscribers, Rules, and CPEs) these pages are for assigning CPEs to a BTS and establishing Quality of Service. These pages apply to the BTS only (for setting up CPEs). Before continuing to configure the BTS, read about the Status page and learn what the information displayed is all about, then go the Configuration Web Page topic and begin configuring the BTS. The Status page is the initial screen you ll view when you enter a CPE or BTS IP address in a web browser s URL field. On the left of the page are navigation buttons for the four AirMAX configuration web pages (Status, Configure, Test, Statistics, and Policy Add CPEs). Clicking on any of the buttons takes you to the corresponding page. Since you re already at the Status page, that button highlights showing you re there. Shown on the right side of the Status page are the current settings of the CPE or BTS system you re configuring. Each of the fields and controls are described below. On the Status page, these values are read-only and cannot be changed. If you see a value you want to change, click on the Configure button to go to an editable page.

24-19-D 19 dBi directional CPE antenna, the transmit power must not be set higher than 50 mW (+17 dBm). WARNING Radio this shows radio modem transmitter status as On or Off. Signal Strength a value from 0 to 100, where a higher number indicates higher signal strength. Signal Quality value indicates relative signal quality. Cell ID a unique number used by CPEs to associate with a BTS that has a matching SSID. Installation and Configuration Configuring the BTS 31 LAN MAC all Ethernet devices have a unique 48-bit media access control (MAC) address built into them when manufactured. An example of a valid MAC address is 00:08:21:31:4e:8f . The field will contain ff:ff:ff:ff:ff:ff when radios have not yet been associated. LAN IP the IP Address is a 32-bit address in a dotted decimal notation. Each of the four fields of the IP can have a value from 1 to 255. For example, here is an IP address: 201.252.100.111. LAN Mask a bit mask used to select bits from an Internet address for subnet addressing. Subnet addressing is a way to segment devices and nodes on a network for efficient use of network addresses and for controlling data traffic. Routers use the subnet mask to decide which data packets are forwarded or stay on the local network. The mask is 32 bits long and is used to select the network portion of the Internet address and a number of bits of the local portion. For example, 255.255.255.0 specifies 24 network bits and 8 local host bits. Default Router (BTS only) specifies an IP address for your internet router. Your site s network administrator will know the number that should be in this field. It only needs to be set on the BTS. CPEs display a Next Hop IP field in its place

(discussed later in Configuring the CPE). Wireless MAC like the LAN MAC, except this field specifies the Radio Modem s MAC. The radio modems in the CPE/BTS systems are Ethernet devices and thus each have a distinct MAC address that will be displayed in this field. 3 C o n f i g u r a t i o n 32 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Wireless IP like the LAN IP Address, except this field specifies the Radio Modem s IP. Note: this field cannot be edited. It is provisioned automatically from the BTS. Wireless Mask like the LAN Subnet Mask, except this field specifies the Radio Modem s Subnet mask. Hardware Version the revision level of the electronics contained inside the CPE or BTS system. Malibu Networks technical support may ask you for this value when helping to troubleshoot your system. Software Version the revision level of the software running inside the CPE or BTS system controller as stored in non-volatile flash memory. Malibu Networks technical support may ask you for this software revision level when helping to troubleshoot your system. Radio Hardware Version the revision level of the radio modem on the system controller inside the CPE or BTS system. Malibu Networks technical support may ask you for this value when helping to troubleshoot your system. Radio Software Version the revision level of the software embedded in the radio modem module. Malibu Networks technical support may ask you for this software revision level when helping to troubleshoot your system. REBOOT this button causes the CPE or BTS being configured to reboot its processor and restart the software. Configure Web Page Installation and Configuration Configuring the BTS 33 The Configure web page has many of the same fields as seen on the Status page, however here they re changeable. To make changes to values, you first edit, enter or select the values on the Configure page. Then when you re ready to apply the changes you click on the Apply button at the bottom of the page and the system loads the values inside the actual hardware and software. On/Off values are set with radio buttons (see the Radio Power). Where there are more than two values to choose from, you ll select an item from a pull-down menu (see the Channel field). Fields where you can enter text (such as SSID) consist of an editable field. 3 C o n f i g u r a t i o n After changing values, click here to apply them Figure 3-5. Configure Page 34 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration To perform initial BTS configuration, follow these steps:

1. Enter an SSID value for the base station. All CPEs configured later within the cell will also use this same value. 2. Enter the radio channel number, from one to 14, by using the pull down menu. 3. Enter a power level for the radio modem (typically use maximum). 4. Click on Radio ON button. 5. Enter a LAN IP for the BTS. 6. Enter a Subnet Mask in the LAN Mask field. Later you can change this as directed by your network administrator. 7. Enter a default router for the BTS (get the value from your network administrator). 8. Click on the APPLY button at the bottom of the page. The BTS unit should now be transmitting and ready to pass Ethernet traffic. With the BTS running, you ll now want to add CPEs to its cell area. Installation and Configuration Adding CPEs From the BTS 35 Adding CPEs From the BTS To add CPEs to a BTS fixed wireless broadcast area, you run a web browser from a PC attached to the BTS, just like you did when configuring, but this time you go to the Management screens, specifically the CPEs web page. 3 C o n f i g u r a t i o n This is a list of all CPEs defined so far Figure 3-6. CPEs Page When the page is loaded, you ll see a list at the top showing all the currently defined CPEs for the BTS. If none are yet defined (as shown in the example above), you ll just see the list headings. To add a new CPE to the BTS, follow this procedure and select or make entries in the fields on the page:

1. Enter the CPEs Wireless MAC address. If not known, you can get this data later when 36 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration configuring the CPE. It is used for authenticating the CPE and preventing unauthorized access. 2. Enter a descriptive name for the CPE (for example, CPE1 or LABCPE , etc.). 3. Select a desired bandwidth for the CPE. The value entered is an integer from 0 to 7168 representing Kbps. 4. Enter an IP address for the CPE on its local LAN. 5. In the Netmask field, enter a subnet mask for the CPE address (usually this will be 255.255.255.0, but check with your network administrator). 6. Click the APPLY button at the bottom of the screen. To delete a CPE definition, just highlight it in the list at the top of the page and then click on the DELETE button. Configuring the CPE After you have configured the BTS, and added the CPE

(or CPEs) to the BTS, you re then ready to configure the CPE(s). Configuring a CPE is much the same as configuring a BTS, with some small differences. Here are the steps and differences:

1. Just as when you configured the BTS, connect a PC to the CPE s Power Injector with a crossover cable and repeat the same steps as in Configuring the BTS. 2. Run an Internet web browser on the PC, enter http:/

/192.168.1.1 in the web browser s URL or Location field and go to the Configure web page. This time it will display CPE Configuration at the top of the Configure web page. Installation and Configuration Configuring the CPE 37 Note: If this fails, try pinging the CPE IP address from the PC (pinging is explained in the Configuration Troubleshooting and Testing topic at the end of this chapter). 3. Enter the same SSID value as entered for the BTS. 4. Click the Radio ON button. 5. Enter a LAN IP for the CPE. You can stay with the default; this is only used for initial configuration and troubleshooting. Additional IP addresses and routes are configured automatically based on subscriber IP address configuration. 6. Enter a Subnet Mask in the LAN Mask field. You can stay with the default; this is only used for initial configuration afterward at provisioning, the BTS will set this value when the CPE is added to the BTS. 7. If you have a router connected directly to the CPE, select the CPE Connected to A Router Yes . Then enter the IP address of the router in the Next Hop IP field just below it. 3 C o n f i g u r a t i o n 38 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Figure 3-7. CPE Configuration 8. Click on the APPLY button at the bottom of the page. 9. The STATUS page will be redisplayed: click the REBOOT button at the bottom of the page and wait for two minutes while the CPE reboots and reinitializes the link. Click on the Status button at the left of the display after waiting the two minutes. You should see that the Cell ID field no longer contains all FFs , and now has a new value indicating the CPE has established a link with the BTS. Installation and Configuration Configuring the CPE 39 10.Observe the values in the Signal Strength and Signal Quality fields on the status page. Carefully rotate the CPE directional antenna through a 15 to 30 degree arc in small increments, rechecking the values by clicking the web browser s refresh button and looking again each time. Find the point where signal strength is the greatest. It should be over TBD for proper system operation. Afterward, tighten all antenna mounting nuts to lock the antenna into the final position. 3 C o n f i g u r a t i o n Watch these values as you adjust the CPE antenna direction Figure 3-8. CPE Status, Signal Strength and Quality Fields The CPE unit now passes Ethernet traffic to and from the BTS. You re ready to test the system as a whole. 40 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration QoS Management From the BTS To configure the Quality of Service settings for CPEs and their subscribers, you ll use the Management web pages

(just as you did when adding CPEs with the CPEs web page also one of the Management pages). We ve already described the CPEs page under Management;

now we ll discuss the other pages and their intended purpose:

Service Levels this page allows you to set the type of QoS to be employed, including bandwidth, delay and jitter targets. Subscribers this page associates subscribers with a CPE and configures their TCP/IP parameters. Rules this page establishes the behaviors you want the system to follow when handling communications for a specific subscriber. Items you can control include the service level (defined under Service Levels), IP protocols, payload types, and behavior upstream and downstream from the CPE. Whenever you leave the BTS web pages and return, you ll have to log back on by supplying the username and password ( malibu is the default user without any password until you change it). After logging on, you can select the QoS management page links (Service Level, Subscribers, Rules, etc.) on the left of the display. Changing the password is discussed later in this Chapter. When You Log On Click APPLY to Make Changes Active Changes you make to any of the QoS Management pages do not take affect unless you click on the APPLY button at the bottom of the affected page after changing any values. Installation and Configuration QoS Management From the BTS 41 Service Levels Default QoS Classes, plus any youve created 3 C o n f i g u r a t i o n Figure 3-9. Service Levels Web Page Name Enter a unique name to identify the service level. Type Choose the type of service level; three factory defaults are predefined for you to choose from. Guaranteed is the highest level for the highest priority traffic. Delay and jitter targets may be applied for real-time audio and video traffic. Controlled offers a level for medium traffic without delay and jitter goals. Best Effort is for low priority traffic and only supports maximum bandwidth. Max Bandwidth Enter the maximum acceptable bandwidth for this service. The value selected is an integer from 0 to 7168 representing Kbps. 42 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Min Bandwidth Enter the minimum bandwidth that the system will guarantee for this service level. You must be careful to not over-provision the bandwidth for all active flows. The value selected is an integer from 0 to 7168 representing Kbps. Max Delay Packets exceeding this delay value will be dropped. You should only use this field for video or audio traffic. Using it for TCP/IP data traffic will adversely affect overall system throughput. Max Jitter Packets should arrive evenly spaced with a variation of less than this value. Note: this value must be less than the Max Delay value entered above. Subscribers Figure 3-10. Subscribers Web Page Installation and Configuration QoS Management From the BTS 43 Name Unique subscriber name. CPE Select the CPE that this subscriber is attached to from the list given (showing all CPEs defined thus far). Max Bandwidth Select the maximum bandwidth that the subscriber will be allowed from the drop down list. The value selected is an integer from 0 to 7168 representing Kbps. NAT Enable or Disable network address translation

(NAT) and DHCP for this subscriber. If NAT is enabled, all subscriber LAN addresses will be automatically translated into a single public IP address. IP The subscriber public IP address (as seen from the Internet/WAN side). Netmask Subscriber s network mask that controls how many nodes a subscriber can access. DHCP Subnet If NAT is enabled, you can manually enter the subnet address here. If NAT is disabled, this will be a read-only field showing the DHCP subnet assigned. DHCP DNS If NAT is enabled, you can manually enter the IP addresses of up to three DNS servers, separated by spaces for use by DHCP clients. If NAT is disabled, this will be a read-only field. APPLY button Click this button after making your selections or changes. 3 C o n f i g u r a t i o n 44 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Rules Figure 3-11. Rules Web Page Subscriber select a subscriber from a pull-down list of previously configured subscribers that the rule on this page will be applied to. Class Name a unique name for this rule Class Service Level pull down list of available defined service levels. The name indicates the QoS characteristics for the rule. Class Direction selects the direction of the rule, as either upstream-only, downstream-only, or applying to both directions. Upstream means from the subscriber to the BTS, while downstream means from the BTS to the subscriber. Installation and Configuration QoS Management From the BTS 45 Remote IP enter the range of remote IP addresses that this rule will apply to. Specify both a starting and ending address.

DSCP is part of the IP packet header. 3 C o n f i g u r a t i o n 46 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Changing The Password Although initially the system has no password (only user Malibu ), you can and should set a password to ensure system security. A Password link on the left of the display, under the Management links, takes you to a page where you can set or change password security. Figure 3-12. Password Page 1. The Username field displays the current user; if you wish to change the username, enter the new name in the field, overwriting the current name. 2. If there was a password already defined, it will be shown in the Old Password field. To define a new password, enter it in the New Password field and then enter it a second time in the field just below it, labelled New Password Again. This helps ensure Installation and Configuration Testing BTS to CPE Wireless 47 that you ve entered what you really want and have typed it correctly. 3. When you re sure that you ve got the correct username and password, then click on the APPLY button only then will the changes be made to the system. Note: Always write down username and password changes and store them in a secure place, so you can find them later in the event you forget what they are. Testing BTS to CPE Wireless Communications Testing a basic system consists of pinging the BTS and then the CPE. To test with a Windows PC (other computers and OS platforms also have Ping utilities available, but the exact steps will vary):

1. Connect a Windows PC to the BTS as described earlier in Configuring a BTS and then run a DOS window. On most Windows PCs, you will go to the Start button, look under Programs and then select MS-DOS or MS-DOS Prompt . 2. Ensure that the BTS and CPE are not on the same LAN, so they can only communicate via the wireless link. 3. In the DOS window ping the CPE IP address set earlier during BTS configuration. For example, if the IP address for the CPE is 206.112.23.2, then enter:

>ping 206.112.23.2 RETURN 4. If it pings successfully, you have connectivity between the PC and the BTS. If it times-out and does not ping, ensure you are using the correct IP addresses and review the configuration data and physical installation. 3 C o n f i g u r a t i o n 48 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Test Web Page 5. Verify that you have a subscriber and rules for that CPE (see QoS Management from the BTS presented earlier in this Chapter). During testing and troubleshooting, you may want to use this Test web page to turn Radio and/or Ethernet continuous transmission on and off on one or more CPE and BTS units. Caution: selecting continuous transmission will cause network disruption so it should only be used under test and troubleshooting conditions. On this screen you ll see the following control buttons. Pressing any of these buttons causes an immediate action:

Figure 3-13. Test Page Installation and Configuration Statistics Web Page 49 WIRELESS pressing this button commands the CPE or BTS to immediately begin continuous radio transmission of data from its radio modem which continues until the STOP button is clicked. LAN pressing this button commands the CPE or BTS to immediately begin continuous transmission of data over its Ethernet port until the STOP button is clicked. STOP pressing this button commands the CPE or BTS to immediately stop continuous transmit modes. Note: After running these tests, reboot the system to restore normal operation. Statistics Web Page This web page shows data flow statistics for the CPE or BTS system being viewed. 3 C o n f i g u r a t i o n Figure 3-14. Statistics Page 50 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration WEP To monitor flow, enter a value in seconds in the Update Rate field, select one or more CPEs, and then click on the UPDATE button. Select Manual from the pull down menu and then click the UPDATE button to stop or select a different web page. Wired Equivalent Protocol, or WEP, is the security behind the wireless IEEE 802.11 protocol. With AirMAX systems you do not need to configure WEP; 128-bit WEP with dynamic key exchange is automatically configured and used by the system without any manual operator configuration required. Configuration Troubleshooting and Testing Verify Connections by Pinging Pinging is a simple and reliable way to ensure you have basic TCP/IP connectivity between TCP/IP devices over a network. By running the ping utility on a PC connected to a network and then sending test packets to another device on the network, you can then tell if the link between the devices is working by monitoring packet send times or data loss. To test with ping on a Windows PC, do the following:

1. Ensure the PC is attached to the network and configured with an appropriate subnet mask and IP address. (This was described at the beginning of this chapter in Configuring the BTS.) 2. Open a DOS window from Windows. On most Windows PCs, you will go to the Start button, look under Programs and then select MS-DOS or MS-DOS Prompt . Installation and Configuration Configuration Troubleshooting 51 3. In the DOS window type:

>ping 192.168.1.1 RETURN The ping utility will then send test data packets to 192.168.1.1 the factory default AirMAX IP and measure the time it takes to respond. It also checks whether there is any data loss in the loop. You can use Ping to test any IP address on your LAN or wireless connection. Note: if you ve changed the IP address from the factory default value, then correspondingly change the IP address in the ping parameter shown above. 3 C o n f i g u r a t i o n Figure 3-15. DOS Window Showing Ping Utility If the Ping times out or reports excessive data loss, then re-check your cabling and ensure there is power to the AirMAX Power Injector. If the IP still won t Ping, read the Symptom and Ready table shown next. 52 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Table 3. Symptom and Remedy Actions Symptom or Condition If the browser does not load the AirMAX configuration web page when its IP address is entered Remedy or Action Ping the CPE/BTS from the PC (type Ping <IP> from DOS). Check that the PC running the web browser is configured for the same network as the CPE/BTS being configured (check IP, subnet mask, and router IP, on both CPE/BTS and PC) and inspect physical cabling and connections. CPE/BTS won t Ping from PC

(packets aren t returned Ping times out) Check that the CPE/BTS is properly connected via the Power Injector ethernet cable and that the Power Injector power adapter is connected to AC power. CPE/BTS won t respond to Ping from PC and cabling has been verified Ensure you are using the proper IP address for the CPE/BTS system. If it is fresh from Malibu Networks, it will have the default IP address of 192.168.1.1. If it has been changed, you will need to find out the value it has been changed to. Installation and Configuration Configuration Troubleshooting 53 Table 3. Symptom and Remedy Actions Symptom or Condition Ethernet works, but the radio modem does not Remedy or Action If you can Ping the CPE or BTS from the LAN side, but a PC on another CPE or BTS within the cell area cannot Ping it, then its radio modem may not be working. Enter the IP number of the suspected CPE/BTS from a PC browser attached to its local LAN and then if the AirMAX configuration pages load up, then verify it has a matching SSID value, verify the CELL ID as reported by the BTS is detected by the CPE, check signal strength, ensure power level is at maximum, and if those measures don t remedy the problem, then try rebooting the CPE/

BTS. Also, verify that a subscriber and appropriate rule(s) have been configured for that CPE (see QoS Management From the BTS, presented earlier in this Chapter) 3 C o n f i g u r a t i o n 54 Malibu Networks AirMAX CPE/BTS Chapter 3: Configuration Diagnosing CPE Startup Failures If you are looking at the Status screen for a CPE as it starts up (run a web browser with the CPE s IP address entered in URL field and Status link selected), you ll see a series of messages. The messages run through a specific cycle as the CPE initializes and becomes part of the network. If the CPE halts at a particular message, it can sometimes help you diagnose problem causes. Status Message Area Figure 3-16. CPE Status Page The messages and the order in which they occur, is as follows:

1. Initializing... 2. Searching for Cell ID 3. Initializing WAN 4. Initializing WEP keys 5. Provisioning Installation and Configuration Configuration Troubleshooting 55 The system could also display a status message of WIRELESS DOWN somewhere during this sequence as well. If the CPE halts or freezes up at one of these messages, it could mean:

Message Displayed When Frozen Initializing... Searching for Cell ID Initializing WAN Initializing WEP keys Provisioning WIRELESS DOWN Possible Meaning Serious system problem. Notify Malibu Networks and report occurence. BTS could be turned off or down. Check the CPE SSID setting and antenna direction/positioning. Also check for physical obstructions. SSID is okay if you ve gotten this far; the problem may be inadequate signal strength or quality due to antenna obstructions or terrain. The system should never become frozen on this message. If it occurs, notify Malibu Networks. Wait quite awhile for this message to pass, especially if your system has a lot of CPEs. If it remains stuck, try rebooting the CPE in question.

5/2/2002 5/2/2002 5/2/2002 Appendix C Glossary Glossary of Terms 100BaseT 10BaseT 802.11b Address Address Mask This chapter provides definitions for terms commonly used in telecommunications, computer networking, and wireless equipment. 100BaseT (defined by the IEEE 802.3) uses a star topology, with stations directly connected to a multiport hub, and offers up to 100 Mbps data rate. The standard specifies two pairs of unshielded twisted pair wire for 100BaseTX. 10BaseT implements the IEEE 802.3 Ethernet standard over unshielded twisted-pair wiring using a star topology, with stations directly connected to a multiport hub. It runs at 10Mbits/sec and has a maximum segment length of 100 meters. An IEEE standard for wireless networking. An address is a unique code assigned to a network device. A bit mask used to select bits from an Internet address for subnet addressing. The mask is 32 bits long and selects the network portion of the Internet address and one or more bits of the local portion. Sometimes called subnet mask. Malibu Networks AirMAX CPE/BTS Appendix C: Glossary C-2 AirMAX Backbone Bandwidth Base Transceiver Station (BTS) Bit Error Rate Broadband Broadcast Buffer BW Cache Category 5 Coaxial Cable Malibu Networks wireless broadband access system comprised of a Base Transceiver Station (BTS) that transmits to and from one or more customer premises (CPE) units. Both CPE and BTS units are functionally similar in that they are made up of an antenna, controller card, radio modem and power supply (items contained in ODU and Power Injector units). The primary connectivity path of a hierarchical distributed network. All systems with connectivity to an intermediate system on the backbone are assured of connectivity to each other. Systems can set up private data transfers with each other to bypass the backbone, reducing backbone traffic and providing security. Bandwidth is the difference in Mhz between the highest and lowest frequency a channel can conduct. For example, the bandwidth of a broadcast TV channel is 6MHz. The term also is commonly used to communicate a channels throughput, typically measured in Kbits/sec or Mbps. Transmits to and from one or more customer premises (CPE) systems. A measure of transmission quality generally shown as a negative exponent. Any network that multiplexes multiple independent carriers on a single cable. This is done using frequency-division multiplexing. Broadband technology prevents traffic on one network from interfering with another, because the transfers happen on different frequencies. A packet-delivery system where a copy of a given packet is given to all hosts attached to the network (such as Ethernet). Memory used to temporarily store data that compensates for differences in device transfer rates. Bandwidth. A numerical measurement of throughput for a system or network. A portion of RAM used for temporary storage of data which must be accessed very quickly. The EIA/TIA 568 standard certifies Category 5 up to 100MHz. Coaxial cable has an inner conductor surrounded by insulation and wrapped in metal screen. Customer Premises Equipment End user equipment that resides on the customers premise which may not be owned by the local exchange carrier. CRC DHCP DNS Domain Installation and Configuration Glossary of Terms C-3 Cyclic Redundancy Check. An algorithm that computes a numerical value based on the bits in a block of data to insure the accurate delivery of data Dynamic Host Control Protocol (DHCP) provides a method for automatic IP address allocation via a DHCP server that manages addresses. Domain Name System. The distributed name/address mechanism used in the Internet. See also Domain Name Service. In the Internet, a part of a naming hierarchy. An Internet domain name consists of a sequence of labels separated by periods. Domain Name Service

(DNS) DNS allows you to use a name such as www.malibunetworks.com instead of a cryptic IP address such as 204.33.180.83. DNS names cannot have more than 255 characters. Encryption Enterprise Network Ethernet Data is scrambled into an unreadable form. Later, an application decodes the data when a user-supplied password matches a predefined value. An enterprise network connects all computers and networkable devices in a company and runs the companys mission-critical applications. A network that runs over thick coax, thin coax, twisted-pair, and fiber-optic cable. A thick coax Ethernet and a thin coax Ethernet use a bus topology. Twisted-pair Ethernet uses a star topology. Fiber Ethernet uses a point-to-point method. 802.3 is the IEEE specification; 8802/3 is the ISO specification; and DIX/Blue Book Ethernet is the name of the Digital Equipment Corp., Intel, and Xerox specification. Apple Computer s version of Ethernet is called Ethertalk. File Transfer Protocol

(FTP) The TCP/IP protocol for file transfer. Internet protocol for transferring files between hosts. Filtering Gateway Hop A process used to remove particular source or destination addresses before crossing a bridge or router onto another area of a network. An alternate name for a router. A term used in routing to represent one data link. The network path from the source to the destination consists of a series of hops. C A p p e n d x G o s s a r y i l Malibu Networks AirMAX CPE/BTS Appendix C: Glossary C-4 Host HTTP Hub Indoor Unit (Power Injector) Refers to any device attached to a network providing application-level services. Examples are workstations, file servers, mainframes, etc. Hyper Text Transfer Protocol. A protocol used in the World-Wide Web to deliver data from Web servers to browsers. A multiport repeater, sometimes called a concentrator, that provides an attachment point for multiple network nodes. Hubs often also incorporate bridges, routers, and network-management features. This unit is placed inside the customer s facility and connects the site s 10/100Base-T LAN to the ODU. It also functions as an AC adapter that passes power to the ODU along with data over a special ODU ethernet cable. The Power Injector has two parts, an AC to DC power module that plugs into a 110/220VAC source and a small module

(called the power injector) that has the two RJ-45 ethernet connections (LAN and ODU) and connects to the power module. Internet Address A TCP/IP 32-bit address given to hosts. Internet Protocol (IP) Internet Protocol is a component of TCP/IP. IP is a network-layer protocol defining how packets are transmitted. Internetwork Interoperability Intranet IP IP Datagram A group of networks connected by routers, bridges, and switches. The system is configured so users and devices can communicate with each other, regardless of where they are attached. The ability of equipment made by one manufacturer to work with another s. A private network using standard Internet protocols (TCP/IP, HTTP servers, POP and SMTP servers for mail), typically found in businesses and organizations. An Intranet has no paths outside the organization, thus providing security to its assets. Internet Protocol. The network layer protocol for the Internet protocol suite. Basic building block of information passed across the Internet. An IP datagram is comprised of data, source and destination addresses, and fields that define its contents. The latter includes items such as the header checksum, datagram length, and flags indicating how the datagram can be used. ISP LAN Link Installation and Configuration Glossary of Terms C-5 An Internet Service Provider (ISP) is a company that sells Internet access to organizations or individuals. Data rates offered by ISPs can vary, ranging from 300bps to OC-3. ISPs also sometimes offer help in planning and/or installing your network connection. Local Area Network. A network that moves data between various devices within an organization. A physical or virtual connection between two nodes in different subnetworks. Local Area Network

(LAN) See LAN. Multicast Data packets are sent to a select subset of network addresses, rather than being sent to all network addresses as in a broadcast. Multi-Homed Host A computer having more than one communications data link. Such data links may or may not be attached to the same network. Multiplexing The interleaving of information from multiple connections into one. Network Availability A measure of network uptime versus unplanned outages and downtime. Network Interface Card (NIC) Network NIC Node Noise A network interface card (NIC) plugs into a computer and, when attached to a network and used with the proper software, enables communication over the network. This is usually synonymous with Ethernet card. A system of interconnected computers and other hardware used to exchange data and messages. Networks may be local (LAN) or wide area (WAN). See Network Interface Card. Shortened term for logical node. Electrical signals superimposed over a desired signal due to environmental reasons or design limitations.

The ODU is a ruggedized box, often antenna-mast mounted, that houses a radio modem and connects to an antenna. It also has an ethernet cable that passes both data and power to/from the Power Injector. The radio modem and circuit board inside have flash memory and a standalone CPU that can intelligently communicate with other systems. Remote management software configures and controls the ODU. A link to an outside network node. A base unit of data. In networking, a packet defines the syntax of data transmitted to and from an application. A packet scheduler determines when packets are sent to an intermediate router or final destination, as determined by your route and QoS selection. Self-checking code that uses binary digits to indicate whether the total number of ones (or zeros) in each coded expression are always even or odd. Checks may be made for even, odd, or no parity (checks not performed). Logical nodes grouped to create a routing hierarchy. Nodes can directly begin communication with each other in a peer-to-

peer architecture without an intermediary. A tangible physical link that provides a connection between two switching systems. Physical Medium are actual physical interfaces such as DS1, E1, DS2, E3, DS3, E4, FDDI-based, Fiber Channel-based, STS-1, STS-3c, STS-12c, STM-1, STM-4, and STP. These mediums range from 1.544Mbps through 622.08 Mbps in data rate. Packet internet groper. A utility program that tests whether destinations can be reached by sending them an ICMP echo request and then waiting for a reply. Ping is a useful utility to check whether equipment is performing and connected properly on the network. Ping clients are available for the PC, Macintosh, and Unix computers. Power-Over-Ethernet Cable. This is a category 5 Ethernet cable that also includes power in addition to data signals. The cable is a single interconnect between the ODU and the Power Injector which supplies the Ethernet connection from the LAN and the power via an AC adapter that attaches to the Power Injector. Malibu Networks supplies PoE cables in various lengths. Point of Presence

Identifier assigned by a logical node that notes the point of attachment of a link to that node. This unit is placed inside the customer s facility and connects the site s 10/100Base-T LAN to the ODU. It also functions as an AC adapter that passes power to the ODU along with data over a special ODU ethernet cable. The Power Injector has two parts, an AC adapter power module that plugs into a 110/220VAC source and a small module (called the power injector) that has the two RJ-45 ethernet connections (LAN and ODU) and connects to the power module. In networking jargon, propagation delay is the time it takes for a bit to travel across the network from its transmission point to its destination point. Protocol A definition of data to be sent and the negotiation rules to be followed when sending. Public Data Network

(PDN) A network open to the public and run by a government or service provider for a fee. QOS Quality of Service An acronym referring to the communication quality and data integrity of a network. It reflects whether the network can transport data without losing cells and has predictable delivery of data. Real Time Repeater RJ11 RJ45 The actual passage of time. An event in real time occurs as we would see and experience it in actual time, without delays or compromises. A device that delivers electrical signals from one cable to another without packet filtering or routing. Repeaters usually also boost signal strength to allow longer cable runs than possible with a single cable. A four-wire modular connector used by the telephone system. An eight-wire modular connector used by telephone systems. Special RJ45 modular connectors are also used for 10BaseT UTP cable, but have different electrical properties.

Milewski, each of whom are independent consultants whos services have been retained by Malibu Networks, Inc. to sign applications before the commission on our behalf, to make representations to you on our behalf and to receive and exchange data between our company and the Commission in connection with the certification of the following Telemics product(s):

Malibu Networks AirMax 240 Malibu Networks AirMax 2400 Under FCC Docket number 20780 and General Docket Number 80-284 pursuant to Part 15 of the FCC Rules and Regulations. If you have any further questions or need additional information, please feel free to contact me at 408-

293-5525. 29 June 2002 Date James Allen Executive Vice President and Chief Operating Officer

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 3, 2002 RE:

Malibu Networks FCC ID: QGQ-AM241 After a review of the submitted information, I have a few comments on the above referenced Application. 1) Please upload an exhibit for the operational description of the device. 2) Two different models appear to be covered by this application, while only one unit was tested. Please provide detailed information regarding the differences between these models. 3) Please upload an exhibit for the external photographs of the device (please include photographs of the antennas as part of this). 4) Please note that section 4(a) of the 731 form should list either DSS or DTS as appropriate for this type of product. 5) The test report mentions that there are 2 antenna (12 dBi Omni and 19 dBi panel antenna). The report also mentions that lower gain antennas may be used. Please provide a list of all planned antenna's including type, gain, and antenna connector style of each. Please note that the manual only mentions 4 specific antennas. 6) Please provide a block diagram of the system as tested for radiated emissions. What was the cable lengths between the EUT and the antenna? Is this length always set, or is it variable?

7) Currently TCBs are only authorize mobile classification spread spectrum transmitters in the 2.4 GHz band with both a peak conducted and peak radiated (EIRP) output power not exceeding 200 mW (see attached exclusion list). The EIRP of this transmitter with the + 12 dBi Omni & +19 dBi Panel antenna is greater than 200 mW The FCC is currently working to change or eliminate many of the restrictions on TCBs and the latest information we have from the FCC is that they hope to publish this information shortly (see attached email regarding status of this). Options available for handling this application currently are:

a) We can go forth and review the application in completion (considering the antenna's as mobile), but will have to b) c) wait until the FCC releases the changed exclusion list before we issue the grant due to the RF exposure limitations currently imposed on TCB's. If certain configurations that exceed the 200 mW EIRP limitation can be considered as fixed instead of mobile

(distance of 2 meters between antenna and user instead of 20 cm), then we may be able to go ahead with the application now with adjustments to the MPE calculations and users manual to cover both mobile and fixed installations. If this route is selected, it will affect the suggestive use of certain MPE exhibits and the users manual information given here. Also note that if lower gain antenna's are to be used, then distinguishing information must be provided in the users manual for all types of antennas used (see #5 above as well) If time source based averaging can be applied this may be an additional option for still qualifying under mobile use. However this will depend on the worse case duty cycles inherent to this device and may be complicated to determine. d) Resubmit the application to the FCC. 8) Please provide information to show compliance with the antenna requirements of 15.203. Professional installation must be used if standard connectors are applied (i.e. use of a standard connector is not allowed if professional installation "may" be required or a possible option). Please note that professional installation will require a cover letter addressing the following 3 points:

a) Application (or intended use) of the device b) Installation requirements c) Method of marketing the device. l Page 2 July 3, 2002 Question 9 & 10 as follows are related depending on how the device is classified 9) The label on the EUT displays both the FCC ID as well as the FCC Logo. The use of the FCC logo and the phrase "for home or office use" (for products authorized under Part 15) is reserved for products authorized using a Declaration of Conformity route to compliance. Has this device also been properly tested (as given by ANSI C63.4) as a class B computer peripheral and a test report issued by an accredited test facility? If the device has met with these requirements, also please provide the DoC Statements required by 2.1077 which should be contained on a single page included in the manual or with the product and adjust the labeling information in the users manual to the information given in 15.105(b). 10) The users manual states that the device has met with Class A emissions. However the detailed product information shows residential/SOHO at one point. If the device has met with Class A emissions only, then the label should have the FCC logo and the phrase "for home or office use" removed. Also, a justification as to Class A use only should accompany the application that explains why the device will not be used in a residential area. 11) The test report states "Schematics, block diagrams, and algorithm descriptions subject to enclosed confidentiality statement". The confidentiality letter only lists schematics, block diagrams, and parts list. Please clarify which exhibits are to be held confidential and correct the confidentiality letter if necessary. Please note that the test report may not be held confidential and that any other information contained within the test report that might be considered confidential (i.e. detailed product description) should be removed from the test report and provided in a separate exhibit. 12) The test methodology (page 8 of 39) given in the test report states that the power output was measured with a power meter, however the data given on pages 12-14 appear to be from a spectrum analyzers. Please comment. Note: All of the power output results match the information contained in the plots, except 1 which is off slightly. 13) The power output tested should be performed with the RBW set to greater than the 6 dB bandwidth of the emissions. Since this is not possible on most spectrum analyzers, either a peak power meter should be used, or the power integration function as contained in most modern spectrum analyzers to measure the output power. This will likely affect the power measurements results (test data, RF exposure, 731 form, etc.). 14) From antenna conducted test data provided it appears that spurious emissions may occur within the restricted bands 1660-

1710, 1718.8-1722.2 which could be higher than the harmonics measured. However the radiated test data does not show any measurements around these frequencies. Please comment. 15) Radiated emissions at 7232 MHz (run 1a) do fall in a restricted band. The limit applied is not correct and the reading appears over the limit. Also the note given on this table does not seem applicable to this measurement. Please explain. 16) The plot for the bandedge for the 19 dBi panel antenna at 2.390 GHz (page 37 of 39), appears to show the marker measurement made right at the bandedge. Please note that this measurements should be made to the highest emission in the restricted band region outside the bandedge. It appears that there may be 2 spurious emissions higher than the measurement made at the bandedge. Please comment. 17) Since power output levels will affect compliance of the unit with the FCC's rules, explain what precautions are built into the system to keep the end user from adjusting the power output levels. For example adjustment of this feature is only allowed by passwords used by the installers, etc. (reference 15.15(b)). 18) Please add information to the users manual that easily shows each antenna and its associated maximum power value settings to be used. This may be done through an installers worksheet, or a simple matrix showing all antennas. Timothy R.

The CPE and BTS portions of the system are all outdoor units (ODU) ruggedized for the harshest environments with an operating temperature range of up to 160 degrees F. With this approach, installation times are reduced and the skill-set required is substantially reduced. Reliability and cost effectiveness were key design goals for this system. By utilizing standard, off-the-shelf components Malibu Networks achieves both of these goals. Malibu Networks' product is reliable and takes advantage of volume production resulting that outperforms other competitive solutions on a cost/benefit scale. in a access solution Malibu Networks is pleased to introduce the Malibu Networks AirMAX system designed exclusively for point-to-multipoint operations in the 2.4 GHz ISM band. The system is composed of a BTS, CPE, a full featured Service Management System

(SMS) and Malibu Networks' patent pending QoS implementation, MAXimum IP. TM With the benefits of MAXimum IP a service provider will see an immediate, dramatic increase in their bottom line. MAXimum IP accomplishes this through two primary means. First, by employing MAXimum IP the efficiency of the system is increased resulting throughput improvement of at least 2 times the effective bandwidth as compared to similar systems without MAXimum IP. in a subscriber Second, MAXimum IP offers considerably more than just minimum and maximum bandwidth control per CPE as well as per each subscriber behind the CPE, a claim no other vendor can make today. Maximum IP also gives the service provider the ability to control jitter and latency as well - enabling additional high value services to be sold and supported. Real time traffic such as voice and gaming can now be offered to the end user. The Technology is MAXimum IP. The Product is AirMAX.

Please refer to the installation and configuration guide. This product, BTS and CPE will be professionally installed. Method of marketing the device This product will be sold through telecommunications equipment distributors to ISPs and Corporate IT departments.

Malibu Networks, Inc. 1107 Investment Blvd. Suite 250 El Dorado Hills, CA 95762 10 July 2002 Best Regards, David Waitt RE: Malibu Networks FCC ID: QGQ-AM241 Mr. Johnson, On behalf of Malibu Networks I am pleased to provide you with the following answers to your inquiries. Should you have any further questions or require and clarification on any of these issues, please do not hesitate to contact me at david@waitt.us. Your questions are addressed below 1) Please upload an exhibit for the operational description of the device. MALIBU: Please refer to the Detailed product information section in the test report in addition to the AirMAX CPE BTS Overview document uploaded with this reply. Simply stated, the device is a standard, previously certified, IEEE 802.11 PCMCIA card transceiver and a single board computer (both purchased components) housed in a weatherproof enclosure that is connected to a omni-

directional or directional antenna to provide an IEEE 802.11 data link. The units operates with a maximum transmit power of approximately 100mw in the unlicensed Part 15, 2.4 GHz ISM band and utilizes Direct Sequence Spread Spectrum. 2) Two different models appear to be covered by this application, while only one unit was tested. Please provide detailed information regarding the differences between these models. MALIBU: There is no significant difference between the hardware in each type of unit. Both units use the same single board computer, the same Off the Shelf Cisco Systems IEEE 802.11 radio module (AIR-LMC-350) that Cisco certified under FCC ID: LDK 102040 and the same enclosure. The only differences between the two units

(CPE and BTS) are:

-The firmware contained in the compact flash card and the size of the compact flash card

-The amount of RAM on the single board computer

-The antenna that is connected to the unit. The BTS will typically NOT use the 19dBi panel antenna. Since the CPE and the BTS have two different Malibu Networks model numbers, both were included in the application. 3) Please upload an exhibit for the external photographs of the device (please include photographs of the antennas as part of this). MALIBU: External pictures have been uploaded with this reply 4) Please note that section 4(a) of the 731 form should list either DSS or DTS as appropriate for this type of product. MALIBU: The equipment is DSS. 5) The test report mentions that there are 2 antenna (12 dBi Omni and 19 dBi panel antenna). The report also mentions that lower gain antennas may be used. Please provide a list of all planned antenna's including type, gain, and antenna connector style of each. Please note that the manual only mentions 4 specific antennas. MALIBU: Malibu intends on using four different antennas in the implementation of the system. They are:

MaxRad 8 dBi omni - base model number: MFB24008 (down-tilt as required at particular installation) NCG Company 12 dBi omni (with 3 degree down-tilt) - model number: GP-24-3 ARC Wireless 8.5 dBi panel - model number panel 8.5 ARC Wireless 19 dBi panel - model number panel 19 Given these intended antennas, the highest gain of each antenna type was tested with the unit. The antenna connector of each is an N connector. They will be connected to the BSE or CPE unit via a coax cable. The data sheets on all of the antennae were uploaded with the original application submission. 6) Please provide a block diagram of the system as tested for radiated emissions. What was the cable lengths between the EUT and the antenna? Is this length always set, or is it variable?

MALIBU: The length of the cable used for the radiated emissions tests between the unit under test and the antenna was 4ft. This same length was used for all of the tests and the cable used during the tests is the type that will be shipped with the units. As this is the only cable that will be shipped with the units, the length will be constant throughout the installations. The radiated emissions test setup in the test report has been modified to show the antenna in the setup. 7) Currently TCBs are only authorize mobile classification spread spectrum transmitters in the 2.4 GHz band with both a peak conducted and peak radiated (EIRP) output power not exceeding 200 mW (see attached exclusion list). The EIRP of this transmitter with the + 12 dBi Omni & +19 dBi Panel antenna is greater than 200 mW The FCC is currently working to change or eliminate many of the restrictions on TCBs and the latest information we have from the FCC is that they hope to publish this information shortly (see attached email regarding status of this). Options available for handling this application currently are:

We can go forth and review the application in completion (considering the antenna's as mobile), but will have to wait until the FCC releases the changed exclusion list before we issue the grant due to the RF exposure limitations currently imposed on TCB's. If certain configurations that exceed the 200 mW EIRP limitation can be considered as fixed instead of mobile (distance of 2 meters between antenna and user instead of 20 cm), then we may be able to go ahead with the application now with adjustments to the MPE calculations and users manual to cover both mobile and fixed installations. If this route is selected, it will affect the suggestive use of certain MPE exhibits and the users manual information given here. Also note that if lower gain antenna's are to be used, then distinguishing information must be provided in the users manual for all types of antennas used (see #5 above as well) If time source based averaging can be applied this may be an additional option for still qualifying under mobile use. However this will depend on the worse case duty cycles inherent to this device and may be complicated to determine. Resubmit the application to the FCC. MALIBU: We will reclassify the device as a Fixed device. The modified RF exposure statement appears in the revised manual on page iii 8) Please provide information to show compliance with the antenna requirements of 15.203. Professional installation must be used if standard connectors are applied (i.e. use of a standard connector is not allowed if professional installation "may" be required or a possible option). Please note that professional installation will require a cover letter addressing the following 3 points:

Application (or intended use) of the device Installation requirements Method of marketing the device. MALIBU: Recall that these devices will be sold to Internet service providers and corporate IT departments wishing to provide wireless Internet access to their customers. These units will not be installed or configured by the end user of the system. The systems will be installed, configured and maintained by professionals. In no instance will the end user of the system install the system or have access to the configuration area of the software. Access to the configuration of the system is controlled by a user name and password combination. A letter addressing this point has been uploaded with this reply as well as some pictures of typical installations (professional installation letter here.) Question 9 & 10 as follows are related depending on how the device is classified 9) The label on the EUT displays both the FCC ID as well as the FCC Logo. The use of the FCC logo and the phrase "for home or office use" (for products authorized under Part 15) is reserved for products authorized using a Declaration of Conformity route to compliance. Has this device also been properly tested (as given by ANSI C63.4) as a class B computer peripheral and a test report issued by an accredited test facility? If the device has met with these requirements, also please provide the DoC Statements required by 2.1077 which should be contained on a single page included in the manual or with the product and adjust the labeling information in the users manual to the information given in 15.105(b). MALIBU: The device has been tested to Class B specifications. A DOC has been prepared and is on file at Malibu Systems. The standard statement of 15.105 has been added to the manual. With regard to 2.1077, this appears to only be applicable to equipment that is imported in to the country, Thus, the DOC information that 2.1077 is stating must be in the manual is not applicable. The responsible party will simply be the company listed on the FCC grant. 10) The users manual states that the device has met with Class A emissions. However the detailed product information shows residential/SOHO at one point. If the device has met with Class A emissions only, then the label should have the FCC logo and the phrase "for home or office use" removed. Also, a justification as to Class A use only should accompany the application that explains why the device will not be used in a residential area. MALIBU: The reference to being tested as Class A device is an error. The unit has been tested to and passed the Class B requirements. The reference to Class A has been removed from the manual 11) The test report states "Schematics, block diagrams, and algorithm descriptions subject to enclosed confidentiality statement". The confidentiality letter only lists schematics, block diagrams, and parts list. Please clarify which exhibits are to be held confidential and correct the confidentiality letter if necessary. Please note that the test report may not be held confidential and that any other information contained within the test report that might be considered confidential (i.e. detailed product description) should be removed from the test report and provided in a separate exhibit. MALIBU: The exhibits to be held confidential are indeed:

Schematics Parts lists Block diagrams. The reference to algorithms on the footer of the test report is an error since no algorithms were uploaded with this application. The footer has been removed from the report to eliminate any discrepancies. 12) The test methodology (page 8 of 39) given in the test report states that the power output was measured with a power meter, however the data given on pages 12-14 appear to be from a spectrum analyzers. Please comment. Note: All of the power output results match the information contained in the plots, except 1 which is off slightly. MALIBU: The reference to using a power meter to make this measurement was an error. It has been corrected in the revised report. The incorrect information in the summary table has been corrected as well. 13) The power output tested should be performed with the RBW set to greater than the 6 dB bandwidth of the emissions. Since this is not possible on most spectrum analyzers, either a peak power meter should be used, or the power integration function as contained in most modern spectrum analyzers to measure the output power. This will likely affect the power measurements results (test data, RF exposure, 731 form, etc.). MALIBU: This measurement has been repeated using the same recommended measurement method as is used for UNII devices. RBW=1MHz, VBW=100kHz, and the measurement was integrated over the 6dB bandwidth of the device (11.2 MHz). This measurement was made on the low, middle and high channel for power settings of +17 and +20 dBm. The plots are included in the revised report that was uploaded with this reply. The summary results table in the report has also been modified. 14) From antenna conducted test data provided it appears that spurious emissions may occur within the restricted bands 1660- 1710, 1718.8-1722.2 which could be higher than the harmonics measured. However the radiated test data does not show any measurements around these frequencies. Please comment. MALIBU: Emissions within this band were re-measured in a radiated test setup against the restricted band emission limits. The data is included in this reply as an appendix. None of the emissions exceeded the restricted band limit. 15) Radiated emissions at 7232 MHz (run 1a) do fall in a restricted band. The limit applied is not correct and the reading appears over the limit. Also the note given on this table does not seem applicable to this measurement. Please explain. MALIBU: The emissions in question at 7232.19 MHz does not actually fall within a restricted band. The restricted band is 7250.00 to 7750.00MHz. The emission is outside of the restricted band, the limit applied is therefore correct. The note Noise Floor Measurement simply indicates that in fact there was no visible emission above the noise floor and that the level entered in the table is the level of the noise floor, not the level of any discrete emission. 16) The plot for the bandedge for the 19 dBi panel antenna at 2.390 GHz (page 37 of 39), appears to show the marker measurement made right at the bandedge. Please note that this measurement should be made to the highest emission in the restricted band region outside the bandedge. It appears that there may be 2 spurious emissions higher than the measurement made at the bandedge. Please comment. MALIBU: This test was repeated to ensure compliance. The new results are included in the revised test report uploaded with this reply. The unit does comply with the restricted band emissions requirements. The previous data for the LOW edge measurement with the 19dBi panel has been removed from the report and the new data inserted. There were also some errors in the Summary table in the report that have been corrected. 17) Since power output levels will affect compliance of the unit with the FCC's rules, explain what precautions are built into the system to keep the end user from adjusting the power output levels. For example adjustment of this feature is only allowed by passwords used by the installers, etc. (reference 15.15(b)). MALIBU: Only the installers of the system will have the ability to adjust the power levels. The power levels will be set at the time of installation and are not able to be changed by the und user of the system. Indeed, access to the configuration menus for the units are User name and password protected. 18) Please add information to the users manual that easily shows each antenna and its associated maximum power value settings to be used. This may be done through an installers worksheet, or a simple matrix showing all antennas. MALIBU: The information has been added to the manual and a modified manual has been uploaded with this response. A table outlining the correct power setting vs. antenna has been added to the manual. The table is contained on page 30 of the manual. EMC Test Data Job Number:J47530 T-Log Number:T47221 Proj Eng:Chris Byleckie Class:N/A Client:David Waitt Consulting Model:Malibu Project Contact:David Waitt Consulting Spec:802.11b Test Specifics specification listed above. Date of Test:7/10/2002 Test Engineer:Chris Byleckie Test Location:SVOATS #4 General Test Configuration Objective:The objective of this test session is to perform final qualification testing of the EUT with respect to the Radiated Emissions Config. Used:1 Config Change:

EUT Voltage:120V/60Hz The EUT and all local support equipment were located on the turntable for radiated spurious emissions testing. All remote support equipment was located approximately 30 meters from the EUT with all I/O connections running on top of the groundplane or routed in overhead in the GR-1089 test configuration. For radiated emissions testing the measurement antenna was located 3 meters from the EUT. When measuring the conducted emissions from the EUT's antenna port, the antenna port of the EUT was connected to the spectrum analyzer or power meter via a suitable attenuator to prevent overloading the measurement system. All measurements are corrected to allow for the external attenuators used. Ambient Conditions:

Temperature:33C Rel. Humidity:36%
