Publication History Revision Date Description Rev 1 Rev 2 Rev 3 SEP 2000 DEC 2000 JUL 2001 Initial release of manual. Major stuctural, text formatting, and software changes to manual. Product name change to AWE, Rev 2 version of manual, added features. JUL 2001 Rev 03 xi Notices xii AWE 120-24 Installation & Configuration Guide Description Features The AWE 120-24 is a wireless Ethernet bridge that provides high-speed, wireless connectivity at a fraction of the cost of wired solutions. It operates over the 2.4 2.48350 GHz ISM radio band and has a maximum raw wireless data rate of 12.0 Mbps. Provides wireless connectivity at speeds up to eight times faster than regular T1 lines, making the AWE 120-

24 ideal for providing high-speed Internet access or for wirelessly extending existing communications infrastructures. Supports point-to-point, point-to-multipoint, and multipoint-to-multipoint networks. Contentionless polling ensures efcient access to remote data networks. Is self-contained and easy to use. Simply connect a AWE 120-24 to each LAN segment, and the unit automatically learns where nodes are located on the network and performs dynamic packet ltering to ensure the local LAN trafc does not overload the wireless connection. Uses Wi-LAN's patented Multi-Code Direct Sequence Spread Spectrum (MC-DSSS) technology, which makes the unit spectrally efcient and resistant to interference. MC-DSSS technology increases data throughput by as much as ten times compared to traditional spread spectrum technology. Other features include automatic Tx power level adjustment, IP address ltering, throughput throttling and monitoring, high security and reliability, and a ash-code upgrade path. SNMP, Telnet and RS-

232 management enable users to manage, congure and monitor their wireless network with ease. About Spread Spectrum The FCC allocates three frequency bands (called the ISM bands) to a radio technique known as spread spectrum communication. The bands are located at 900MHz, 2.4 GHz, and 5.7 GHz (shown in the following illustration). The AWE 120-24 operates with spread spectrum technology over the 2.4 2.4835 GHz band. JUL 2001 Rev 03 1 Description License-Free ISM Bands 900 MHz North America 2.4 GHz Worldwide 26 MHz Wide 902 MHz 928 MHz 83.5 MHz Wide 2.4 GHz 2.4835 GHz 125 MHz Wide 5.8 GHz Worldwide 5.725 GHz 5.85 GHz Direct Sequence Spread Spectrum (DSSS) technology converts a data stream into packets and spreads the packets across a broad portion of the RF band. The particular spread pattern depends upon a code. With multi-code DSSS (MC-DSSS), multiple codes and spread patterns are employed. A spread spectrum receiver reconstructs the signal and interprets the data. Some advantages of DSSS are as follows. Fast throughput: A wide bandwidth means fast data throughput. Resistant to interference: DSSS overcomes medium levels of interference and multipath problems. Security: There must be a decoder at the receiving end to recover data (a AWE can only talk to another AWE). Data is transmitted at irregular time intervals. Upon request, Wi-LAN can assign a customer a data packet security code so that a customer can only receive transmissions from another AWE with the same code. Low probability of detection: Due to a low amplitude signal and wide bandwidth. No license fee: A license fee is not required if used in the specied radio bands, transmitter power is limited, and a non-standard antenna connector is used. About AWE Units AWE units can function as base stations, remote units or repeater bases. Base Station:

At least one unit in your wireless network must be a base station. A base station acts as the central control unit of the wireless network. The base station polls all remote units and controls how trafc is routed to and from remotes. The base usually connects to a major access point of the wired network. The antenna of the base station must be capable of transmitting and receiving radio signals to and from all the remote units in a system. If remotes are spread over a large area, an omni-directional antenna is usually required. See

, page 15 for information about setting up a base station. Conguring a Base Station 2 AWE 120-24 Installation & Configuration Guide Some System Applications Remote Units: Remote units receive and transmit wireless data to the base station. You need at least one remote unit for each wireless link. Remotes can limit the amount of data passed by the remote (a function called throttling), and they can lter data packets based on their IP address. Because remote units communicate only with the base station, their antennas can be more directional and have higher gains than base antennas. See Conguring a Remote Unit, page 18 for information about setting up a remote unit. Repeater Base: A base station can be congured as a repeater base. A repeater is needed when remote units cannot communicate directly with each other, but direct transfers of data between them are necessary

(as in a true WAN). When congured as a repeater, the base station passes data packets between remote stations based on the remote group status and a list of MAC (Media Access Control) addresses that the base station automatically builds. The repeater uses a method called "store and forward" to receive data from the orignating remote and to pass data to the destination remote. See Setting a Base to Repeater Mode (Base Station Only), page 79 for more information. Some System Applications You can build a wireless network from AWE units and various other components such as cables and antennas. The following section shows some simple examples of AWE applications. Making a Simple Wireless Bridge The simplest example of using a AWE 120-24 is a point-to-point wireless bridge that connects two wired network segments or LANs. Two AWE units are required: a base station and a remote unit. Point-to-Point Wireless Bridge Wireless Link Remote Base Main Wired Network Router Hub Switch Firewall Wired Network Router Switch Hub Firewall Creating a Simple Wireless Network You can create a point-to-multipoint wireless network by adding several remote units to a base station. A base station can support up to 1000 remotes, however, Wi-LAN recommends no more than 225 remotes per base station to esnure high levels of data throughput. See Determine the Number of Remotes, page 113 for more information.

Remote-to-Remote Communication Remote Wireless Links Main Wired Network Remote Base Remotes must be in the same RF group to communicate directly Remote 4 AWE 120-24 Installation & Configuration Guide Some System Applications Creating a Network with Cells Cells or data nodes can be created with AWE units to maxmimize coverage, minimize interference, and increase data throughput. Directional antennas are mounted on a mast to divide cells into sectors.Each sector is connected to an antenna and a base station. Directional antennas increase signal gain within the sector and increase the distance possible between base stations and remotes. Center frequency, acquisition code and antenna polarization techniques are used to isolate sectors. The increase in data rate depends on the number of sectors. For example, the data rate of Cell 1 in the diagram below is 36 Mbps (12 Mbps x 3 sectors). Cells are distributed across a service area and can be linked to each other via a wireless link or a ber optic cable.

The repeater passes data around the obstacle to any remote in the same RF group. The single unit repeater slows data throughput due to the "store and foreward" process where each packet is handled twice. A dual unit repeater does not slow data throughput.

Ensure that a basic RF link exists between a base station and a remote unit Test the ability of the link to carry test data Perform a simple network test Establishing a Basic RF Link This test ensures that a basic RF link exists between a base station and a remote unit.

! Important The quality of your digital data transmission depends greatly on the quality of your RF link. Always try to establish a high-quality RF link rst. A high-quality RF link will result in high-quality data transmissions and a low BER. A low-quality RF link will result in low-quality data transmissions and a high bit error rate (BER). Digital data can always be sent across a high-quality RF link. If the RF link is of poor quality, data either cannot be sent at all or will contain too many errors to be useful.. Tip: Congure one unit as a base station, then use it to test all the remote units. To establish a basic RF link 1. Ensure that one unit is congured to a base station, select a center frequency and set the test minutes. See Conguring a Base Station, page 15. 2. Ensure that the other unit(s) are congured as remote units and with the center frequency the same as the base station. See Conguring a Remote Unit, page 18. 3. Place the base station and a remote unit at least two meters apart with a clear line of sight between antennas. For directional antennas, point antennas toward each other. For a dipole antenna, orient the antenna vertically. 20 AWE 120-24 Installation & Configuration Guide Basic Test Setup 4 Bench Test Units Indoor Antenna 2 m minimum Indoor Antenna Coax Adapter Cable Coax Adapter Cable Air Mode Wire Power Air Mode Wire Power Air LED = orange Base Unit Air LED = orange Remote Unit 4. Power up the base station. The green Power LED is ON. The Air LED of the base unit is red. This Air LED color indicates that the unit is transmitting data but is not receiving a response. (The reason is that the remote is powered off.) 5. Power up the remote unit. The green Power LED is ON. The Air LED of the remote unit turns orange and the Air LED of the base station also turns orange as both units send and receive data from each other. Orange is the normal Air LED color. The color of the Air LED during this step indicates the following conditions. Orange (both stations) Units are continuously sending and receiving sync packets Red (base station) Stations are congured incorrectly, and the base station is transmitting without receiving acknowledgment Green (remote station) Stations are congured incorrectly, and the remote station is receiving packets to which it cannot respond Off Nothing is being received (by the remote) or transmitted (from the base) Note: If antennas are placed too close together (< 2 m), the strong transmit signal can saturate the receiving unit. Fine-tune antennas by changing antenna orientations until the Air LED is orange. Next, you will test the links basic ability to carry data. JUL 2001 Rev 03 21 Installation Testing a Basic RF Link When both the base station and remote unit can receive and transmit data to each another (indicated by orange Air LEDs on both units), a basic RF link is established. You can now test the link with Link Monitor. Link Monitor tests a link by sending and receiving test data over a link, in both directions, at the same time. For information about testing a link in the receive or transmit direction only, see Performing Link Monitor Test

(Normal Mode), page 52. To test the RF link 1. Connect the test PC to the Serial port of the base station or remote unit. See Connecting PC to Serial Port, page 15. 2. Log in to the unit and go to the Main Menu. 3. Select RF Station Configuration and press Enter. The RF Station Conguration window is displayed.

If the power is

> 55 dB the receiving unit is probably being saturated. If you have problems ensure the unit is congured to its basic default settings (see Restoring Factory Congurations, page 101) and recongure the unit, or contact Wi-LAN technical assistance center. 6. When you nish viewing link monitor statistics, disable Link Monitor to remove the overhead test data from the wireless link. To disable Link Monitor, select RF Station Configuration from the Main Menu and press Enter. The RF Station Conguration window is displayed. Select Link Monitor Period and press Enter. The eld is highlighted. 7. 8. Type 0 in the eld and press Enter. The link monitor test ends. 9. Press Esc to exit to Main Menu. Note: You can also set the Tx power automatically. See Setting Tx Power Automatically (Remote Station Only), page 63. You have now established an RF link between two units, tested the ability of the link to carry test data, and adjusted the Tx power level. Next, you connect the units to a network and perform some simple network tests. Performing Simple Network Tests To test units within a simple network you require two AWE 120-24 units, a LAN connection, a PC and a crossover ethernet cable or hub connection. To perform network tests JUL 2001 Rev 03 23 Installation 1. Connect the Ethernet port of the remote unit to the wired LAN. 2. Place a ferrite block on the Ethernet cable and power cord, approximately 4 cm from jacks. Ethernet Connection Antenna Power Ethernet Port Ferrite block Ethernet Power cord Ferrite block Ethernet cable To wired LAN or PC Internet port 3.

See Network Conguration, page 39 for information about AWE Internet addresses. See Appendix C: Conguring a Simple Data Network, page 129 for information about conguring simple peer-to-peer networks. 6. Create some network trafc to test the wireless link. For example, use ping or ftp put and get to transfer a large test les, in both directions, across the link. The WIRE LED on the AWE indicates link le transfer activity to the wired LAN. When the le transfer is done, ftp displays the size of the le and the time it took to transfer the le. This information can be used to measure the data throughput of the wireless link, and is very useful for troubleshooting. Using ping and ftp ping From the command line prompt, type:

C:> ping IP Address Example:

ping 192.163.2.88 ftp To connect to the node, from the DOS prompt, type:

C:> ftp IP Address For instructions about using ftp, type "help"

at the ftp prompt. ftp> help Follow the instructions. 7. Test all units in the network. JUL 2001 Rev 03 25 Installation 5 Install Units This section provides some guidelines about installing units in the eld. Install the units at locations identied in the network plan. Some units will simply sit on a table or desk and do not require any special antenna work. Other units must be installed inside communication cabinets or racks and will require professional antenna installation. CAUTION Never operate a unit without an antenna, dummy load, or terminator connected to the antenna port. Operating a unit without an antenna, dummy load, or terminator connected to the antenna port can permanently damage a unit.

!

WARNING Antennas must be professionally installed following accepted safety, grounding, electrical, and civil engineering standards. Verify that there is no interference at the site by performing spectrum sweeps with a spectrum analyzer. Perform sweeps at various times of the day (for example, 9AM, noon, and 3 PM are peak telephone trafc times.) If there are problems, contact the network planner, who may need to change the system conguration or design. Sweep antennas and cables with the Site Master communications test set, before securing antennas and cables to towers, while they are on the ground and easy to access. Sweeping helps to ensure that antennas and cables will operate as expected. Initially install equipment with exibilitydo not tie down cables, antennas should be free to move, allow some slack in cables, avoid drilling and do not seal connections. Align antennas. (Two people are required, one at the base station and one at the remote unit. When in the eld, you may require binoculars and 2-way radios to communicate.) When aligning antennas, adjust the orientation of the remote antenna while running a link monitor test between the remote and the base station. Adjust the antenna until you achieve the highest fade margin with no bit errors

(BER = 0). See Performing the RSSI Test, page 57 and Performing Link Monitor Test (Normal Mode), page 52 for instructions. Repeat the antenna alignment procedure for each remote. When antennas are aligned and cables are secured, sweep the antennas with the Site Master test set a nal time before connecting to AWE. Perform diagnostic tests on the installed system. Compare eld results to bench test results using ping, ftp, fade margins, etc. Document your results (these results will be very useful when troubleshooting and monitoring the systems performance). When the system works as specied in the network plan, lock down and weatherproof all equipment and connnections. 26 AWE 120-24 Installation & Configuration Guide 6 Test Network Point-to-Multipoint Installation The procedure for installing a point-to-mulitpoint system is the same as the procedure for installing a point-

to-point system. Treat each link in a point-to-multipoint system as a single, point-to-point wireless link. Co-Location Installation When you install a system with sectors and co-located base stations (see Creating a Network with Cells, page 5 for an example), you install and test sectors as if they were point-to-point systems; however, in this case you must ensure that individual sectors are not interfering with each other. Align and test the rst sector. Measure the fade margin and run the link monitor test. Document your results, then turn off the radio in the rst sector. Align and test the second sector. Measure the fade margin and run the link monitor test. Leave the link monitor test running in the second sector. Turn on the radio in the rst sector again and run the continuous tranmit test. See Performing Transmit and Receive Tests, page 55. Observe the BER and fade margin of the second sector radio. Look for changes to determine if the rst sector is interfering with the second sector. Repeat the tests for all sector/pair combinations. 6 Test Network Run the link monitor test, transmit test and network tests such as ping and ftp le transfers to verify operation when the units are installed in the eld. See Performing Link Monitor Test (Normal Mode), page 52. Adding to a Network Always add to your network one link or device at a time, working from a known base network. Measure and document changes to the system and changes in performance. For example, you can transfer les with ftp and measure the performance with LAN analyzer software. The key to a successful network is to proceed one step at a time and to understand your network!

JUL 2001 Rev 03 27 Installation Network Test Setup Indoor Antenna Indoor Antenna Base Unit Remote Unit Air Mode Wire Power Air Mode Wire Power PC LAN 10/100 BaseT HUB PC with LAN analyzer software Preventative Maintenance and Monitoring You should set up a preventative maintenance schedule for your network. Wi-LAN recommends that the following preventative maintenance be performed at least semi-annually. Regularly run link monitor tests across the network and measure BER and fade margin. You can also test the network with ping, ftp and le transfers. Other resources are available on the Internet that can help you monitor the performance of your link. If you have SNMP application software, you can check unit operation from a remote location. See Appendix D: SNMP, page 135 for more information. You should periodically perform a physical inspection of each site. Check that antennas and cables are secure and have not become loose. Check for physical obstructions in the line-of-sight radio path, such as trees and buildings. Sweep antennas and cables to ensure that antennas and cables are intact and operating properly. Check that there are no water leaks in cabinets. Check weatherproong. Check for new sources of electromagnetic interference. 28 AWE 120-24 Installation & Configuration Guide Conguration Overview This section explains how to use the Main Menu to congure and test your AWE unit, and to obtain useful statistical and maintenance information.

JUL 2001 Rev 03 41 Configuration IP Filter Conguration Two different IP lters are available: a packet lter, and an address lter. The IP packet lter determines which type of packets are allowed to pass through a unit. If the IP Packet Filter is OFF, the unit passes all packets. If the IP Packet Filter is ON, the unit passes only IP and ARP (Address Resolution Protocol) packets. IP address lters are actually tables that contain lists of IP addresses. If an address is listed in the table, the unit will pass data packets to other IP addresses. If it is not listed, the unit will not pass data packets. Air IP Address Filter Table xxx.xx.xx.x xxx.xx.xx.x xxx.xx.xx.x IP Addresses Wire Data packets pass only if the IP address is listed in the IP filter table Each IP address lter is dened by a range and a base value. IP address ltering improves system security and helps manage data throughput. Viewing IP Filter Conguration To view current IP lter conguration 1. From the Main Menu, select IP Filter Configuration and press Enter. The IP Filter Conguration menu is displayed.

JUL 2001 Rev 03 61 Configuration Adjusting Throttling (Remote Station Only) Throttling enables you to control the rate that data passes though a remote, so data throughput can be adjusted to make the data rate compatible with the rest of the system. Throttling restricts the ow of data from air to wire or from wire to air. When throttling is enabled, the amount of data passed is equal to the throttling level times 64 kbps, to a maximum of 6.4 Mbps. Throttling applies to both down link and up link trafc, so a throttle level of 1 means the unit will pass 64 kbps in each direction. A throttle level of 50 means that 50 x 64 kbps will be passed. When throttling is disabled, the unit uses the maximum available bandwidth. The default setting is to disable throttling. To enable throttling 1.

Three modes of operation are available: Normal mode is used to run Link Monitor normally. Link Monitor tests the link and collects statistical information about link operation, which can be viewed with the Link Statistics screen. Automatic Output Power runs Link Monitor through one "cycle" and automatically adjusts Tx power based on measurements taken during that cycle. Power is automatically reduced by the unit if Tx power is too high and is increased if it is too low. Dynamic Output Power runs Link Monitor in the background and periodically adjusts Tx power in response to the current radio conditions and environment. The amount of bandwidth

(test overhead) required by Link Monitor is set with Link Monitor Period. (See Setting the Link Monitor Period, page 59). How Automatic Output Power Adjustment Works Link Monitor tests a link by sending test packets and measuring the links performance (in terms of BER and power). The results of the test can be used to automatically adjust Tx power. Automatic power level adjustment is explained below. The maximum Tx power output (factory-set power ceiling) of a unit is set at factory and cannot be changed with conguation menus (for more information see Unit Identication, page 34). A user-specied power ceiling or limit can be set by the user using User Output Power Adjust Ceiling on the RF Station Conguration screen. The user-specied ceiling is the maximum Tx power level with which the user allows the unit to operate. Factory-set Power Ceiling User-specified Power Ceiling Automatic power adjustment moves power level up and down Signal Power Signal Margin Noise Floor l e v e L r e w o P 0 Operating Tx Power Level

(Base Tx Power Level + Signal Margin) Base Tx PowerLevel The noise oor is the power level below which signal quality deteriorates rapidly due to random radio interference causing the link to not function properly. Base Tx Power level is the starting power level or

"base" from which the adjustment is made. The operating Tx Power level is the sum of the base power level and the signal margin (fade margin)the signal margin is added to the Tx base power level and moves with it. Both the base power level and the signal margin can be adjusted to reach the operating power level. When a unit adjusts the power level, it begins at the base power level and runs Link Monitor. If no bit errors occur and the power level is satisfactory, the unit automatically drops the Tx power level by one dB and runs JUL 2001 Rev 03 63 Configuration Link Monitor again. If no bit errors occur again and power level is adequate, it once again drops the Tx power level by a dB and runs Link Monitor. This process repeats until a power level occurs where no bit errors occur and power level is satisfactory. This level is the minimum power level required for operation and is displayed numerically by Current Output Power Level Adjust on the screen. When the unit reaches this level, Tx Power (seen on the Radio Module Conguration screen) is automatically reset to the new level. (Below this level, BER and power levels are unsatisfactory for data communication). If the intitial base Tx power level is below the noise oor, a unit will automatically increment the power level by one dB until the BER and power level become satisfactory. In short, two methods of automatic power level adjustment are available: automatic and dynamic. Automatic Power Output: Power is monitored and automatically adjusted once when the unit is powered up or rebooted. Dynamic Output Power: Power is monitored and automatically adjusted periodically during regular operation. Some bandwidth for data is lost due to test packet overheadthe amount of overhead is determined by setting the Link Monitor Period (see Setting the Link Monitor Period, page 59). Note: Tx Power Adjust on the Radio Module Conguration screen is used to set the initial or base Tx power level. After the level is set automatically, this value is automatically reset by the unit. The reset value can be read by viewing Current Output Power Level Adjust on the RF Station Conguration screen, or by viewing Tx Power Level Adjust on the Radio Module Conguration screen.

(with the same RF Group number) can communicate via the repeater. (See Setting Remote Unit RF Group, page 83 for information about RF groups.) The following diagram expains the process. Repeater Mode 2 Message is stored and broadcast to all remotes in RF Group n Base Repeater Mode = on Rank = 4

JUL 2001 Rev 03 81 Configuration Setting Dynamic Polling Level (Base Station Only) Dynamic polling improves system performance by reducing overhead due to idle remote units. A base station automatically learns which remote stations are active and which are idle. The base station waits a brief time period for a remote to respond to a poll. If the remote doesnt respond within the time period, the base considers the remote to be idle. (This process is called dynamic time allocation or DTA.) Idle remote units are ignored by the base station for the number of polling rounds entered in the Dynamic Polling Level eld. The higher the dynamic polling level, the more efcient the throughput and the longer it takes to move a subscriber from an inactive state to an active state. Dynamic Polling improves system performance whenever there is more than one remote. When there are a large number of remotes system performance improves signicantly. Note: Polling level is set only at the base station. To set the dynamic polling level 1. From the Main Menu, select RF Station Configuration and press Enter.

For example, in a system consisting of a base station and associated remotes, you can: 1) assign units to different groups so that only members of the same group can communicate with each other and the base (an open system); 2) isolate remotes so they cannot talk to other remotes, but can talk only to the base (a closed system); 3) assign remote units to groups and congure the base station as a repeater (a closed system); and 4) combine closed units with open units in the same system. These congurations are explained below. Remote units with the same RF group number (RF Group = 1 63) can communicate directly with each other and with the base station (if there is a line-of-sight RF path between units and base station Repeater Mode =

off.) An example is a company where the Human Resources department needs direct access to the Payroll department, but the two departments must be isolated from other departments. Since HR and Payroll are in the same RF group 14, they can talk directly to each other, but they cannot talk directly to other groups such as R&D, which belongs to RF Group 20. Example 1: Open System Repeater Mode = off Base Remote RF Group = 20 R&D RF Group = n n = 1 63 Remote RF Group = 14 Human Resources Remote RF Group = 14 Payroll Remote units congured as RF Group = 0 are independent, closed units. Closed units cannot talk directly to each other, they can only talk directly to the base station. This setup acts to isolate remote units and the associated LANs from each other. Example 2 shows a situation where independent companies are connected wirelessly to a single base station and communication between the companies is prevented. Example 2: Closed System Repeater Mode = off Base Remote RF Group = 0 Company 1 Remote RF Group = 0 Company 2 Remote RF Group = 0 Company 3 RF Group = 0 JUL 2001 Rev 03 83 Configuration A repeater is used to bypass obstacles that block the RF path (for example, a mountain). When a base station is set to repeater mode (Repeater Mode = on), it can pass data from remotes in an RF group to other remotes in the same group. A system with a repeater is a closed system. Example 3 shows a repeater with four remotes. All the remotes are in the same RF Group 4, so they can talk to each other via the repeater base. Example 3: Repeater Conguration (Closed System) Repeater Mode = on Base Closed System Remote Remote Remote RF Group = 4 n = 1 63 RF Group = 4 n = 1 63 Mountain RF Group = 4 n = 1 63 No direct communcation possible due to obstacle Remote RF Group = 4 n = 1 63 Closed remote units (RF Group = 0) can be combined with open remote units (RF Group = non-zero) within the same system. In this case each group in the system behaves according to its RF Group characteristics:

closed remotes could communicate only with the base, remotes with the same (non-zero) group number could communicate with each other, and remotes with different (non-zero) group numbers could not communicate with each other. A base or repeater would not pass packets originating from a closed remote. The following table summarizes the rst three situations. Repeater Mode

Wi-LAN recommends the following practices. Maintain the integrity of the system design when adding or changing a system. The introduction of new elements to a system can cause problems unless the network plan is revised to take into account the changes. For example, improper installation of a co-located antenna can add unwanted system interference. Measure and document system performance at the time of the original installation. Monitor system performance regularly. Environmental change as well as normal wear and tear on components can affect system performance. Perform preventative maintenance every 6 months. See Preventative Maintenance and Monitoring, page 28 for information. After periods of extreme weather, perform link monitor tests to verify the system; inspect towers, antennas, cables and connectors for damage. Change menu passwords so that only key personnel can recongure the system. See Setting Menu Passwords, page 94. Keep records of recent changes. Especially document the addition of units, hardware and software changes and changes to conguration settings. Conguration errors often cause other problems. Current records can be compared with original installation records and function as a benchmark to help you troubleshoot. Keep a log of past and present problems and solutions. Store the log on-site, if possible. The log identies common failure points and xes. Before contacting Wi-LAN for customer support, document the symptoms of the problem and the steps taken to diagnose and x the problem. Record the current conguration of the system. JUL 2001 Rev 03 107 Troubleshooting Troubleshooting Areas There are ve key areas to be aware of when troubleshooting. Network Integrity: Continued performance and reliability of a network depends upon maintaining the integrity of the network. If you change a networks design, you will affect its operation. Be aware of recent changes to your network. Quality of RF link: Data communication depends rst on the quality of the RF link. If you can establish and maintain a high-quality RF link, then you can be sure the link will carry high-speed data. If the quality of the RF link is degraded for some reason, the quality of the transmitted data will also degrade. Radio Hardware:There are three basic parts to a AWE: radio unit, antenna feed (cable, connectors, surge suppressors, patch cables etc.) and antenna. You can isolate faulty hardware using measurement and/or replacement methods. Verify the radio unit with diagnostic tests (such as RSSI and link monitor tests), bench test a unit, or replace a unit. Verify the antenna feed with a Site Master test set. Sweep cables, connectors and lightning suppressors, or exchange these parts for known good parts. To verify the antenna you can sweep the antenna with the Site Master test set or exchange the antenna. Correct Unit Conguration: Units must be congured correctly, according to the network plan. Conguration errors can cause an inability to communicate or poor performance. The addition of units or changes to your system may require you to change conguration settings. Embedded Software: Operate with a proven software image. Download new software if you suspect that a units software is corrupted. The following chart provides answers to some of the more common problems that can occur when installing and using a AWE wireless ethernet bridge. 108 AWE 120-24 Installation & Configuration Guide Troubleshooting Areas Troubleshooting Chart Indication High BER Possible Cause Suggested Corrective Actions Signal strength is too low Perform RSSI test to determine fade margin Align or change antennas or cables Ensure LOS between antennas Signal strength is too high Adjust antennas Increase distance between units Interference Bad radio (Tx/Rx) Bad antenna Bad cable Bad connectors Change center frequency Increase RF power Change polarization of antennas Physically isolate antenna from source of interference or change physical location of antenna Bench test radio Exchange radio Visually inspect antenna for damage Sweep antenna Replace antenna Visually inspect cable Replace cable Visually inspect connectors Replace cable/connectors Noisy power supply Replace power supply unit Temperature Determine ambient operating temperature is too high or low Increase or reduce ambient temperature.

This section provides some general guidelines for planning a wireless link, including the following:

Planning the physical layout of your system Determining antenna and cable requirements Determining conguration settings for units Calculating a link budget Planning the Physical Layout You need to plan the physical layout of your wireless system. Ensure LOS (line-of-sight) exists between units and determine coverage areas Determine the number of remotes Measure the distance between the base station and each remote unit Consider the need for equipment shelters, electrical power and environmental requirements Determine the Number of Remotes Since the 12 Mbps data rate is shared between all units, the fewer the number of remote units, the faster each wireless link. Although a maximum of 1000 remotes is supported per base station, this number would result in low data rates. Instead, to ensure high data rates, Wi-LAN suggests a standard where 75 remotes can maintain constant 128 kbps communication with a base station. Since it is unlikely that all units will be active at the same time, the total number of remotes for planning purposes can be increased by a factor of three, so that a maximum of 225 (3 x 75) remotes per base station is recommended. This should enable all users to easily achieve 128 kbps performance. Ensure LOS and Determine Coverage Area Ensure the availability of a clear, LOS (line-of-sight) radio path between base station and all its remotes. Plot the coverage area of each base station on a map, and determine which base station will service which remote unit. Plan some alternate links in case base station coverage areas overlap or if physical obstacles block the radio path to some remotes. JUL 2001 Rev 03 113 Appendix A: Planning Your Wireless Link Measure the Distance Between Units Use a mapping method or GPS (global positioning system) to measure the distance between the base station and each remote, and check the radio path to identify any obstructions in the site path between the two antennas. Due to the high frequency and low output power permitted in the ISM bands, no obstructions can exist between the base station antenna and the remote unit antennas. Determine Shelter, Power and Environmental Requirements AWE units must be located in a weatherproof environment (a room, EMS cabinet or shelter) with an ambient temperature between 0 and 40 Celsius, and humidity from 0 to 95% non-condensing. Consider building, electrical power, heating and air conditioning requirements. Determining Antenna and Cable Requirements If you plan to install a unit indoors, on-site testing is advised because all interiors are unique. You need to consider several factors. Ensure a clear line-of-sight radio path is available between each remote and its base station. Ensure that Fresnel zone clearances are met. Identify obstructions that could degrade link performance now and in the future. Obtain permission from building owners if you intend to install the antenna on a rooftop Obtain 24-hour access to antennas, cables and equipment Determine antenna mounting positions: the nal position should be selected to enable physical shielding of the antenna at the back and sides from radio interference in the ISM band. Consider potential wind load and ice loading impact on the antenna Be aware of possible multipath effects: installing an antenna too close to reective surfaces can cause signal problems. Check local regulatory restrictions, such as height, on antenna mast usage in the identied location Determine transmission cable lengths and plan cable routes. Minimize the length of the coaxial cable Ensure that your antenna is properly grounded and installed according to local electrical codes. because the longer the cable, the greater the cable losses. Calculate the fade margina minimum 15 dB fade margin is required to ensure the reliability of your wireless link. Determine Ethernet cable lengths and plan cable routes.

WARNING Correct antenna installation is critical to the safe operation and performance of your system. Antennas should always be professionally installed. More information about antennas is provided in Antenna Basics, page 120. 114 AWE 120-24 Installation & Configuration Guide Determining Unit Configuration Settings Determining Unit Conguration Settings Conguration settings of units should be determined before installation to ensure easy installation and to reduce installation costs. An information sheet should be prepared for each unit that species the basic conguration settings of that unit.

Calculating a Link Budget Proper path planning ensures that each end of the RF link receives sufcient signal power to maintain the desired Bit Error Rate (BER). The effectiveness and reliability of your RF link depends on several factors. Antenna gain and other characteristics Distance between antennas and obstructions in the RF path Location and height of antennas Length and type of coaxial cable connecting the unit to the antenna These factors are considered when you calculate your link budget. The calculation indicates, on paper, if your radio link is feasible over a given distance and path and if your RF link meets regulatory requirements. Link budgets are typically expressed in decibels (dB). The following variables are used to calculate the link budget. Variable Description System Gain Maximum path loss that the system can support for usable data transmission EIRP (Effective Isotropically Radiated Power) Power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses and antenna gain Antenna Gain Gain of the antenna over a dipole (dBd) or theoretical (dBi) Propagation Loss Signal loss experienced as it travels through the air, expressed in dB JUL 2001 Rev 03 115 Appendix A: Planning Your Wireless Link Variable Description Fresnel Radius Distance around line-of-sight that must be clear of obstacles Cable Loss Path Loss Signal loss experienced as it passes through the coaxial cable, expressed in dB Total loss from one end of the path to the other. Includes propagation losses, cable losses and any other losses that impact the system performance Each variable is described below. System Gain The system gain of a radio system is the difference between the transmitted power and a receivers sensitivity threshold. The system gain of the AWE 120-24 is calculated as follows. Formula:

Variables:

System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER Tx Power = 20 dBm Receiver Sensitivity = 81 dBm (receiver sensitivity @ 10-6 BER) Calculation:

20dBm (81) dBm = 101 dB To ensure reliable communications, the system gain plus all antenna gains must be greater than the sum of all losses. For a reliable link, Wi-LAN recommends that the system gain plus all antenna gains be greater than the sum of all losses by 15 dB. This amount is the fade margin. EIRP (Effective Isotropically Radiated Power) EIRP is the power that radiates from an antenna, taking into account the output power from the transmitter, the connector and cable losses, and the antenna gain. Unlike the Tx output power of the devices, EIRP takes account of antenna gain and cable losses. Antennas use directional gain to increase the effective radiated power. Losses such as cable losses reduce the effective radiated power. You calculate the EIRP as follows. Formula:

EIRP = Tx Power (dBm) - Cable Losses (dB) - Connector Losses (dB) + Antenna Gain (dBi) Note:

The FCC regulatory body has set the EIRP limit to +36 dBm for point-to-multipoint applications per FCC 15.247(b)(3)(i). For point-to-point applications, the FCC EIRP can be 3 dB higher than +36 dBm for every 1 dB less Tx power below 30 dBm. Industry Canada species the EIRP limit to +36 dBm for point-to-multipoint as per RSS-139 Annex B. In accordance with ETS 300-328 for 2.4 GHz RLANs, the maximum EIRP shall not exceed

+20 dBm, with a maximum SPD (Spectral Power Density) not exceeding +10 dBm/MHz. Conrmation is required with the relevant European national radio communications local authority for deviations from this specication. 116 AWE 120-24 Installation & Configuration Guide Calculating a Link Budget Antenna Gain To ensure the best range and interference suppression, the external antenna should be directional, focusing the radio energy in one direction (toward the other end of the link) rather than onmi-directional. Use of a directional antenna also reduces interference from other systems operating at the same frequency. Note: In some situations, you may want to use an omni-directional antenna in your system design. For example, you would use an omni-directional antenna for a base station with remote sites situated in a 360 path around it. When you select an antenna from the list, pay particular attention to the gain specication. When you select an antenna for a remote station, select an antenna with a gain that provides at least 15 dB fade margin. Antenna gain is specied in either dBi or dBd. When an antenna is specied in dBd, add 2.14 dB to the value to convert it to dBi. Propagation Loss Propagation loss is the attenuation (reduction) in RF signal energy as it travels through space. In most wireless systems, losses through space are the major contributor to signal attenuation. When you know the intended installation locations of the base and remote stations, determine the physical line of sight distance and then calculate the RF attenuation as follows:

Formula:

Attenuation (dB) for 2.4 GHz band = 100 dB + 20log(dkm) where:

dkm = Distance in Kilometers 100 dB = Pathloss Constant in the 2.4 GHz band Fresnel Zone It is essential that you locate your antennas at maximum above-ground height to ensure that all ground-based obstructions are cleared from the Line of Sight path and the Fresnel Zone. The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF path. Fresnel Zone First Fresnel Zone Line of Sight Fresnel Radius The maximum Fresnel Radius indicates that this path must be kept clear of obstructions. Ground JUL 2001 Rev 03 117 Appendix A: Planning Your Wireless Link For the 2.4 GHz band, the approximate is Fresnel Radius calculated as follows. Formula:

)2 Cable Loss Cable and connector losses affect the operation of the wireless link and therefore should be kept to a minimum by minimizing cable lengths and carefully selecting the type of cable. The two primary coaxial cable specications for the AWE 120-24 are:

Cable must be 50 ohms nominal impedance Cable must be of a low loss type The following is an example of cable loss ratings at 2.4 GHz. Cable Type LMR400 LMR600 LDF2-50 LDF4-50A LDF5-50A LDF6-50 Loss (dB/meter) 0.22 0.144 0.190 0.128 0.073 0.053 Note: When you calculate path loss, you will add 1dB at each end of the link to compensate for connector losses in addition to the cable loss value. Path Loss Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector loss. Use the following formula to calculate path loss. Formula:

Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss Once you know the path loss, you can compare the value to the system gain value. If the system gain value is greater than the path loss, the link is feasible. See System Gain, page 116 for more information about system gain. Fade Margin Fade margin is the amount by which the system gain plus the total antenna gain exceeds the path loss. Formula:

Total antenna gain = Tx Antenna Gain + Rx Antenna Gain As calculated, the fade margin is the number of dB that the received signal strength exceeds the minimum receiver sensitivity. You require some level of fade margin for any wireless system to compensate for RF path fading due to weather conditions or multipath interference. The Wi-LAN recommended fade margin for the AWE 120-24 is a minimum of 15 dB. The sum of the cable losses, connector losses, propagation losses, and the 15 dB required fade margin should be less than the sum of the system gain and antenna gain. 118 AWE 120-24 Installation & Configuration Guide Link Budget Example Link Budget Example Formulas:

System Gain = Tx Power Rx Sensitivity Antenna Gains = Tx Antenna Gain + Rx Antenna Gain Cable Losses = Base Cable Losses + Remote Cable Losses Connector Losses = Base System Connector Losses + Remote System Connector Losses Desired Fade Margin = 15 dB Tx Power = 20 dBm Rx Sensitivity = 81 dBm Tx Antenna Gain = 21 dBi Rx Antenna Gain = 21 dBi Propagation Loss for desired range of 10km = 100 + 20 x log(10) = 120 dB Tx Cable Losses (5m LMR400) = 5 * 0.22 = 1.1 dB Rx Cable Losses (5m LMR 400)= 5 * 0.22 = 1.1 dB Tx Connector Losses = 1 dB Rx Connector Losses = 1 dB Variables:

Variable Calculations:

Actual Fade Margin Calculation:

System Gain = 20 - (-81) = 101 dB Antenna Gains = 21 + 21 = 42 dBi Cable Losses = 1.1 + 1.1 = 2.2 dB Connector Losses = 1 + 1 = 2 dB Actual Fade Margin = 101 + 42 120 2.2 2 = 18.8 dB Analysis:

A goal of Actual Fade Margin 15 dB is achieved. The values for cable and connector losses in this example are only for illustration. You will need to work these out for your specic installations. JUL 2001 Rev 03 119 Appendix A: Planning Your Wireless Link Antenna Basics Antennas focus and absorb radio energy in specic directions, depending on their design. AWE 120-24 antennas must be tuned to 2.40000 2.48350 GHz. This section contains basic information about antenna parameters and how to select and install antennas for use in your wireless system. Antenna characteristics, mounting location, and correct operation of antennas are critical to a wireless link. Antenna Parameters Parameter Description Gain Antennas have a gain associated with them, which is a measure of their ability to amplify signals in their tuned band Antenna gain is achieved by focusing the signal. A higher gain antenna has a more compressed signal dBd vs. dBi Antenna gain must be measured over a known reference and is often expressed as either dBd or dBi dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a donut shaped radiation pattern dBi is antenna gain referenced over an isotropic radiator which is a theoretical antenna that radiates equally in all directions (e.g. the sun) Wi-LAN references antenna gain in dBi. The conversion factor is 0 dBd = 2.14 dBi Beamwidth Describes how a signal spreads out from the antenna, and the range of the reception area Beamwidth is measured between the points on the beam pattern at which the power density is half of the maximum power. This is often referred to as the 3 dB points A high gain antenna has a very narrow beamwidth and may be more difcult to align Downtilt or uptilt Some antennas have either an associated downtilt or an uptilt. The tilt further focuses the signal downward or upward with respect to the horizon Tilt may be either electrically built into the antenna or achieved mechanically with the mounting gear Downtilt or uptilt may be required when there is a signicant deviation between the elevation of the remote site(s) and the base site F/B Front-to-back ratio Directional antennas focus the signal in a forward path. Achieved by directing the signal in one direction that reduces the signal in the opposite direction A higher gain antenna typically has a greater F/B ratio 120 AWE 120-24 Installation & Configuration Guide Antenna Basics Parameter Description XPD Polarity and Cross-Polarization Discrimination (XPD) Antennas have an associated polarity, which is the orientation of the radiating element with respect to earth Antennas are usually described as vertical, horizontal, or circularly polarized. The polarity of all antennas used in a system must be the same Cross-Polarization Discrimination species the signal isolation achieved when the receiving element is perpendicular to the radiating element. Can be advantageous when co-locating radio systems VSWR Voltage standing wave ratio VSWR is the voltage ratio of minimum to maximum across a transmission line A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of 1.5:1 For example, when using a radio with a 4 W output with an antenna VSWR of 1.5:1, the reected power will be 160 mW Implementation Considerations Some key items to consider when selecting and installing antennas for your wireless network follow. Item Description Absorption Antennas mounted too close to soft objects, such as trees, may experience a reduction in signal strength due to absorption Absorption is most often encountered in applications installed during the fall or winter months, and the problem does not become evident until the spring Diffraction Diffraction occurs when a radio signal reects or bounces off of a solid object. Level of diffraction could lead to connectivity problems if the remaining signal level is too low Two types of diffraction are shadowing and multipath Shadowing Shadowing is a form of diffraction that is typically caused when antennas are mounted too close to a structure and they lose a portion of the signal lobe due to reection The receive antenna is in a shadowed area To minimize shadowing, ensure that there is adequate height above structures when mounting antenna equipment Multipath Interference Multipath is a form of diffraction in which the reected signal arrives at the receiver at different times which confuses the receiver Multipath may be interpreted as interference by the receive antenna and can result in bit errors and processing delays JUL 2001 Rev 03 121 Appendix A: Planning Your Wireless Link Selecting Antennas There are several factors to consider when selecting the right antenna for a wireless application. The following are some initial questions you should ask before selecting an antenna. What is the operating frequency range?

Will this be a point-to-point or point-to-multipoint application? Ensure that you consider if the application will change in the future?

What are the coverage requirements?

What is the gain requirement?

What is the elevation of the remote site(s) with respect to the base station and will additional downtilt/uptilt be necessary at either the base or remote site to compensate?

Will there be any obstructions in the path?

Will systems be co-located? What polarity will be used?

What are the regional environmental conditions? For example, is there windloading, salt air, excessive moisture, ice buildup etc.?

What is the antenna lifetime expectation?

What are the site and mounting options?

What are the restrictions in the locale regarding the effective radiated power permitted from the antenna?

Will antenna appearance be a factor?

In Europe, this value is reduced to 100 mW or 20 dBm. Note: EIRP = Power out of unit Power lost in cable + Gain in power from Antenna Fade Margin See Calculating a Link Budget, page 115 LOS Line of Sight (LOS) LOS is a football shaped pattern known as the Fresnel Zone, which must be kept clear of obstructions.

Installing Antennas Antennas must be installed professionally to ensure that the antenna operates properly and follows accepted safety, electrical, grounding and civil engineering standards.

!

WARNING Ensure the following conditions. Dipole antennas are oriented vertically (point up). Antennas for the system have the same polarity (vertical, horizontal or circular). Connectors attaching the coaxial cable to the antenna are properly weatherproofed. A drip loop is formed at the building entrance to prevent water owing down the coaxial cable and entering the installation building. The coaxial cable is secured to the supporting structure at one meter intervals to prevent wind damage and frost loading problems. The antenna is rmly attached to the mast to prevent it from falling, yet has some exibility so you can move the antenna to ne-tune its position. JUL 2001 Rev 03 125 Appendix A: Planning Your Wireless Link The coaxial cable is connected to the antenna and to the Antenna port on both sides of the link (base and remote stations). Antennas are grounded properly. Fine-tuning Antennas You can ne-tune the antennas by physically moving the antenna. When the remote antenna is correctly aligned, the Air LED is orange, indicating communication with the base station. You can use the Receive and Transmit Tests to test the link while adjusting the antennas to minimize BER and lost packets and maximize received power. You can use the RSSI Test to maximize RSSI. Once antennas are adjusted to maximize performance, secure them properly to the support structures. Co-locating Units When AWE antennas are located on the same mast, you must take care to ensure the output power from one radio does not overpower another co-located bridge, even if the units are operating on different channels. You may need to install a signal attenuator to lower transmit power, use antenna polarity to your advantage, or adjust antenna uptilit or downtilt. Contact Wi-LAN Technical Assistance Center for antenna and installation assistance when co-locating units. 126 AWE 120-24 Installation & Configuration Guide Appendix B: Using HyperTerminal The Windows 95/98 operating system includes a terminal emulation program called HyperTerminal.

SNMP agent software is contained in every AWE unit. Agent software enables a unit to interpret SNMP (Simple Network Management Protocol) MIB (Management Information Block) commands. SNMP management software is installed on a networked PC or workstation and enables a network administrator to remotely manage AWE units. If you have SNMP manager software installed on a networked PC or workstation, you can congure, monitor and control AWE units via the Ethernet or air. SNMP network management software is available commercially and as shareware (for example, you can download a free evaluation copy from www.mg-soft.com). MIB is simply a list of objects that SNMP can monitor. You can download a proprietary Wi-LAN MIB le from www.wi-lan.com or obtain a copy through the Wi-LAN Technical Assistance Center. The AWE 120-24 is MIB version 2 compliant. After you download the MIB le, you must compile the le with the SNMP management software compiler. SNMP Elements SNMP Element Manager Agent Management Information Block (MIB) Description Software installed on the networks host computer and operated by the network administrator. From the host, the Manager congures Agents or polls Agents for information Software that runs on each unit. An Agent accepts conguration commands from the Manager and collects network and terminal information specied in the MIB A database that is accessed by a specic set of commands and executed using the SNMP manager. There is a standard MIB and a Wi-LAN customized MIB that stores information relevant to the operation of a wireless network JUL 2001 Rev 03 135 Appendix D: SNMP Wi-LAN Object Identier Nodes The AWE 120-24 uses SNMP version 1, which is MIB 2 compliant. All OID (Object Identier) nodes in the 120-24 private Wi-LAN MIB are numbered 1.3.6.1.4.1.2686.2.n where n is a private Wi-LAN MIB node number or branch of nodes. All nodes containing statistical information are cleared on power up and reset.

The displayed color depends on the proportion of received data to transmitted data. The LEDs are mostly green when more data is received than transmitted, and mostly red when more data is transmitted than received. When approximately equal amounts of data are received and transmitted at the same time, the LEDs is orange, which is the color that results from combining equal amounts of red and green.

This section explains how to use FTP to download a new software image to a AWE unit. Before you can download a new software image you need the following items. A copy of the software image le A PC connected to the AWE unit via the network Basic network software installed on your PC, including ftp, ping, telnet, SNMP manager (optional) Obtaining New Software Images Contact the Wi-LAN Technical Assistance Center (TAC) to acquire new image les. TAC can help determine what les you require and the most convenient way to deliver it to you. See Customer Support Contacts, page x. Downloading Image Software 1. Obtain the new image les. (Image les may be delivered on oppy diskette, CD-ROM or another delivery method may be used.) 2. Open a DOS session on your PC. From Windows, choose Start, Programs, MS-DOS Prompt. 3. Copy the new image les to a known directory, for example c:\wilan\images. (Create a new directory if a suitable directory does not already exist.) This directory is an example only. C:> copy <image filename> c:\wilan\images 4. Go to the directory by typing cd c:\wilan\images and press Enter. 5. List the contents of the directory. Type dir and press Enter. The names of image les should be listed in the directory. JUL 2001 Rev 03 153 Appendix G: Upgrading Software 6. Type ftp <IP address> and press Enter where the IP address is the address of the AWE unit. The PC connects to the AWE unit. This IP address is an example only. Enter the IP address of your AWE unit. c:\wilan\images>ftp 192.168.3.85 Connected to 192.168.3.85 220 Wi-LAN AWE 120-24 Ethernet Bridge FTP Server User (192.168.3.85(none)):

Note: ftp must be installed on your PC. 7. Type "awe" or "hopper" and press Enter. The password prompt appears. c:\wilan\images>ftp 192.168.3.85 Connected to 192.168.3.85 220 Wi-LAN AWE 120-24 Ethernet Bridge FTP Server User (192.168.3.85(none)):awe 331 Password required Password:

8. Type the supervisor password for the unit and press Enter. (Supervisor access is required to change AWE unit settingssee Setting Menu Passwords, page 94). The ftp> prompt appears. 9. After the ftp prompt, type the following "put" command. ftp> put .\<image filename>

Note: Leave a single space after "put."

Type bye and press Enter to exit ftp and return to the DOS window. 12. Activate the new software image. See Activating New Software Images, below. Activating New Software Images After you download new image les to a unit, you need to congure the unit to operate from the new image rather than from the current image. If you are on-site, you can use the Main Menu to select the default image. See Setting Default System Image, page 99. If you are at a remote location from the unit, you can use telnet to access the units conguration menu or use SNMP manager software (SNMP parameter = defaultImage) to choose the default image le. See Appendix D: SNMP, page 135. Removing Old Software Images To delete old software images from a AWE unit, you must use ftp to connect to the unit, log in as a

"supervisor" and delete images using the "ftp delete" command. Images The amount of ash memory available to store images is limited. To see the amount of memory available, see Viewing System Revision Information, page 36. JUL 2001 Rev 03 155 Appendix G: Upgrading Software 156 AWE 120-24 Installation & Configuration Guide Glossary A absorption Antennas mounted too close to soft objects, such as trees, may experience a reduction in signal strength due to absorption. Absorption is most often encountered in applications installed during the fall or winter months. The problem does not become evident until the spring when leaves appear. acquisition code To minimize the effects of interference, all units in a system use the same acquisition code so the receivers can distinguish the desired signal from other interfering signals. agent In an SNMP context, the agent runs on each unit. An agent accepts conguration commands from the manager and collects network and terminal information specied in the MIB. antenna A device which accepts electromagnetic energy from a circuit or wire and radiates it into space rather than conning it. antenna gain Gain of the antenna over a dipole (dBd) or isotropic (dBi). Antennas have a gain associated with them, which is a measure of their ability to amplify signals in their tuned band. Antenna gain is achieved by focusing the signal. A higher gain antenna has more compressed signal. ARP Address Resolution Protocol. A low-level protocol that maps IP addresses to Ethernet addresses. An ARP request is sent out to the network along with an IP address. The node with the address responds to the request with a hardware address so the transmission can take place. attenuation Any loss in signal strength, due to resistance, absorption, capacitance or any characteristic of the medium or design of the system. JUL 2001 Rev 03 157 Glossary B C base station The central control unit of the wireless network. A base station polls remote units and controls how trafc is routed to remotes. The base usually connects to a major access point of main wired network. beamwidth The beamwidth of an antenna describes how a signal spreads out from the antenna as well as the range of the reception area. Beamwidth is measured between the points on the beam pattern at which the power density is half of the maximum power. This is often referred to as the -3 dB points. A high gain antenna has a very narrow beamwidth and may be more difcult to align. BER Bit Error Rate. A percentage of bits per million, showing the number of bits in error compared to the data bits actually sent. blocking Blocking is an operating mode where the radio receives only. Unblocked is the normal operating mode. cable loss The signal loss experienced as it passes through the coax cable. Expressed in dB. channel The part of the spectrum band occupied by a radio signal, usually measured in kilohertz (kHz). closed system A system where remotes cannot communicate directly with each other. They can only communicate with each other via a base station. coaxial cable A type of wire where the inner conductor is surrounded by an outer conductor. The outer conductor serves as an electrical shield. co-location Refers to placing base stations or units in the same location. In this situation, base stations or units can interfer with each other unless steps are taken to isolate the systems from one another (such as aligning antennas or using different channels). collision The situation that exists when two users try to send a signal over the same medium at the same time and the signal uses the same frequencies. conguration menus Menus that allow the viewing and setting of unit parameters. 158 AWE 120-24 Installation & Configuration Guide contentionless polling A form of dynamic polling that ignores idle remote stations. The number of polls that an idle remote is ignored can be set to maximize polling to active stations. Cross-Polarization Discrimination See XPD. D dB Decibel. A relative measure of power used to specify power gains and losses. The difference in power P1 and P2 expressed in dB is P1 P2 log dB 10

(

) DB9 A D-shaped connector with 9 pins. dBd dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a donut shaped radiation pattern. Gain of a Standard Dipole = 2.14 dBi. dBi dBi is antenna gain referenced over an isotropic radiator which is a theoretical antenna that radiates equally in all directions (e.g. the sun). Wi-LAN references antenna gain in dBi. The conversion factor is: 0 dBd = 2.14 dBi. dBm A power measurement referenced to one milliwatt. This is an absolute measure of gain. diffraction Diffraction occurs when a radio signal reects or bounces off of a solid object. The level of diffraction could lead to connectivity problems if the remaining signal level is too low. Two types of diffraction are shadowing and multipath. downtilt Some antennas have either an associated downtilt or an uptilt. The tilt further focuses the signal either downward or upward with respect to the horizon. A tilt may be either electrically built into the antenna or achieved mechanically with the mounting gear. An downtilt or uptilt may be required when there is a signicant deviation between the elevation of the remote site(s) and the base site. DSSS Direct sequence spread spectrum. A method of expanding the radio signal over a broad portion of the radio band. dynamic polling (DP) A polling protocol in which idle units are not polled as frequently as active units. Since less time is spent polling idle remotes, there are more available resources for active units and overhead is reduced. JUL 2001 Rev 03 159 Glossary E F dynamic time allocation (DTA) A process for determining how active a remote unit is. A unit is allowed a brief time to respond to a poll before the remote is considered idle. EEPROM Electrically Erasable, Programable Read Only Memory: non-volatile memory. EIRP Effective Isotropically Radiated Power. EIRP is the amount of power that is transmitted to the air from the antenna. EIRP levels depend on the power of the radio transmitter, the size of the antenna and the losses incurred in the antenna cable. To remain license exempt, the EIRP must remain under 4 watts or 36 dBm in Canada and the United States for point-to-multipoint applications. In Europe, this value is reduced to 100 mW or to 20 dBm. Note: EIRP = Power out of unit Power lost in cable + Gain in power from antenna ERP Effective Radiated Power. The power radiating from an antenna, taking into account the output power from the transmitter, connector losses, cable losses and the antenna gain. ETSI European Telecommunications Standards Institute. fade margin The amount that the system gain plus the total antenna gain exceeds the path loss is called the fade margin. The fade margin is calculated as the number of dB that the received signal strength exceeds the minimum receiver sensitivity. ltering Filtering limits certain data packets or IP addresses from being passed by a unit. FHSS Frequency hopping spread spectrum. A method of spreading a narrowband signal across a wide radio band by "hopping" the signal as a function of time. Flash memory A type of electrically erasable non-volatile memory that can easily be erased without removal from a unit. fresnel zone The zone around the line of sight between two antennas. It consists of one of a

(theoretically innite) number of a concentric ellipsoids of revolution that dene volumes in the radiation pattern of a (usually) circular aperture. 160 AWE 120-24 Installation & Configuration Guide G I front to back ratio (F/B) Directional antennas focus the signal in a forward path. This is achieved by directing the signal in one direction that reduces the signal in the opposite direction. A higher gain antenna typically has a greater F/B ratio. ftp File transfer protocol. A network utility program for moving les between nodes. gain The ability of a device to amplify a signal. Gain is the ratio of output power divided by input power, usually expressed in decibels (dB). Gain can also be measured as an absolute value, referenced to an input signal of 1 mW (dBm). For antennas, gain measures the ability of an antenna to focus a signal and is expressed in dBd (half-wave dipole reference) or dBi (isotrophic raditator reference). gateway The access point between one LAN and another LAN that would otherwise be incompatible with each other. It is usually a hardware device that steers communication between networks while performing code and protocol conversions. IEEE Institute of Electrical and Electronics Engineers. image An image is a collection of congurations or settings for a particular device. The System Image File contains a collection of congurations that are used when the unit is rebooted. interference Any signal that tends to hamper the normal reception of a desired signal. Equivalent to jamming except considered non-hostile in origin. IP Address A number assigned to a network node, domain or subdivision. The number consists of four numbersthe rst two numbers identify the network and subnetwork and the last two numbers identify unique nodes in the network. ISM Industrial, Scientic, and Medical. It consists of three license-exempt radio bands in North America and some European countries. It is also referred to as part 15.247 in the FCC regulation that denes the parameters for use of the ISM band in the U.S., including power outputs, spread-spectrum, and noninterference. JUL 2001 Rev 03 161 Glossary L M O 162 link monitor A utility that sends known data over an active system to test the reliability of the RF link. The link monitor information is overhead, that is, it reduces the amount of available payload for message data. LOS (Line of Sight) A clear, visual line of sight between antennas. When standing at the antenna position, you must be able to see the remote antenna. An elliptical pattern around the line of site, known as the Fresnel Zone, must be kept free of obstructions MAC address Media Access Control address. Alphanumeric characters that uniquely identify a network-connected device. To prevent unneccesary trafc over a radio channel, units automatically learn the MAC addresses of equipment connected to the local Ethernet segment and do not transmit over the radio channel if the destination is local. A packet entering a subscriber unit from the radio port is not sent to the Ethernet port unless the destination MAC address has been learned from packets entering the Ethernet port. manager When used in SNMP, this element is installed on the networks host computer and is controlled by the network administrator. From the host, the manager congures agents or polls agents for information. MIB Management Information Block. The MIB is a database which is accessed by a specic set of commands that you can execute using the SNMP Manager. There is a standard MIB and a Wi-LAN customized MIB that stores information relevant to the operation of a wireless network. multipath interference When a radio signal is transmitted, it can reect off of physical objects in the environment and take various paths to the receiver. As a result, the signal can arrive at a receiver at different times, confuse the receiver, and cause bit errors and processing delays. OID nodes Object Identier Nodes. These are the individual nodes in a MIB. See SNMP and MIB. open system A system where remote units can communicate directly with each other and with the base station. AWE 120-24 Installation & Configuration Guide P R overhead Anything that reduces the payload capacity of a system is overhead, even if it serves a useful function. The link monitor data is used to determine transmission statistics, but it reduces the message carrying capacity of a wireless link and is considered overhead. path loss The total loss from one end of the path to the other. This includes propagation losses, cable losses and any other losses that impact the system performance. PN Pseudo-random noise. A code used to change a narrowband signal into a spread spectrum signal. polarization The orientation of the radiating element of an antenna with respect to earth. The polarizaiton of antennas is usually described as being vertical, horizontal or circular. point-to-multipoint A wireless system where one base unit communicates with many remote units. The base unit polls all the remotes and data passes between units to complete the network. point-to-point The simplest wireless system consisting of a base and one remote. polling The base unit in a point-to-multipoint system handles multiple remotes by polling each one sequentially. When a base polls a remote, data exchange between that remote and the base takes place. The remote cannot exchange information with the base until it is polled again. propagation loss The signal loss experienced as it travels through the air. Expressed in dB. RF Radio Frequency. A system of communication using electromagnetic waves propagated through space. Because of varying characteristics, radio waves of different lengths are used for different purposes and are usually identied by their frequency. remote unit A unit that can communicate with a base station or other remote units. A remote unit forms a wireless link between a network segment and a base station. repeater base A repeater base rebroadcasts packets received from a remote unit to other remote units. Remote units that cannot see each other (do not have LOS) can communicate through a repeater base. JUL 2001 Rev 03 163 Glossary S T 164 RS-232 Standards for serial communications, which dene the voltages, currents, data rates and other factors about the signals to be used, as well as single-ended, differential, multi-drop operation. RSSI Received Signal Strength Indicator. Strength of received signal expressed in dB. The unit measures RSSI as a fade margin value. scrambling code A code used to scramble messages, so that only units with the same scrambling can read the messages. sensitivity The minimum signal strength required for usable performance by a unit. Expressed in dBm. shadowing Shadowing is a form of diffraction that is typically caused when antennas are mounted too close to a structure and lose a portion of the signal lobe due to reection. The receive antenna is in a shadowed area. To minimize shadowing, ensure that there is adequate height above when mounting antenna equipment to a structure. SNMP Simple Network Management Protocol. A protocol you can use to remotely manage a network element by polling, setting terminal values, and monitoring network statistics and events. It is the de facto internet work management standard, designed to provide a mechanism for the exchange of management information in a TCP/IP-based Internet environment. spread spectrum (SS) Any of a group of modulation formats in which an RF bandwidth much wider than signal bandwidth is used to transmit information, resulting in a greater immunity to noise interference. system gain The maximum path loss that the system can support for usable data transmission. system image le A unit uses system image les to store system conguration settings. The default system image le is called factory-image and is used when the unit is rst powered up. telnet An Internet communications protocol that enables a computer to function as a terminal working on a remote computer. A computer with a network connection to a unit can use telnet to access its conguration menus. AWE 120-24 Installation & Configuration Guide U V W X throttling Throttling limits the amount of data that a remote station passes. This feature is used to improve overall system performance by adjusting the throughput of a unit to match the throughput of other devices in the network. uptilt See downtilt. VSWR (Voltage Standing Wave Ratio) VSWR is the voltage ratio of minimum to maximum across a transmission line. A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of 1.5:1. For example, when using a radio with a 4 watt output with an antenna VSWR of 1.5:1, the reected power will be 160 milliwatts. W-OFDM Wide-band orthoganal frequency division multiplexing. A method patented by Wi-LAN that divides a channel into several sub-channels, spreading the signal over the subchannels and correcting errors without having to retransmit. W-OFDM permits several independent channels to operate within the same band, enabling multipoint networks and point-to-point systems to be overlaid in the same frequency band. XPD (Cross-Polarization Discrimination) Antennas have an associated polarity, which is the orientation of the radiating element with respect to earth. Antennas are usually described as being vertically, horizontally or circularly polarized. The polarity of all antennas used in a system must be the same. XPD species the amount of signal isolation achieved when the receiving element is perpendicular to the radiating element. This can be advantageous when co-locating radio systems.
