The EasyST is designed to work with WiMAX compliant base stations including the base station products in the AS.MAX family. The EasyST, which uses Intel Corporations Pro/Wireless 5116 broadband interface, connects IP-enabled devices directly to WiMAX networks and can be installed indoors by end users within minutes without the need for costly professional installations by an operator. EasyST is designed for the residential and small enterprise markets, providing high-speed broadband Internet access and a Fast Ethernet connection to the subscriber's local area network

(LAN). EasyST models support IP services at speeds of up to 37 Mbit/s over-the-air gross rates over channel bandwidths of up to 10 MHz in both uplink and downlink. EasyST is available in numerous ETSI frequency bands, operating in FDD and TDD modes in numerous channels, see: EasyST Frequency Ranges and EasyST-2 Frequency Ranges. EasyST is also available in a multi-mode model (EasyST-2) based on the Rosedale chipset which supports both TDD and FDD. Note: EasyST-2 is presently available for frequencies, 3.43.6 and 3.63.8 only. EasyST uses the OFDM signaling format, providing non line-of-sight (NLOS) performance. EasyST utilizes QAM, QPSK, and BPSK modulation technologies by modulating transmitted signals and demodulating the received signals where the original digital message can be recovered. The use of adaptive modulation allows EasyST to optimize throughput, yielding higher throughputs while also covering long distances. EasyST is typically deployed with a clip-on antenna, which is attached directly to the EasyST's top panel. However, for deployments in rigorous terrains, the EasyST can be attached using an RF cable to an external window-mount antenna to provide strong radio coverage. The EasyST's compact design allows it to be deployed alongside the end-user's PC by simply placing it on a desktop (or mounting it to a wall when using an external antenna. Easy-to-read radio signal strength LED indicators on the EasyST's top panel enable the end user to position the device in the optimum location, ensuring service availability and reliability, while increasing service speed and reducing network load. EasyST provides 10/100BaseT interface with the subscriber's LAN. In addition, the EasyST provides an interface for adding plug-in expansion modules to provide support for features such as:

WiFi and LAN Switch (EasyWiFi module) VoIP and battery backup (EasyVoice module) EasyST is powered by an AC/DC power adapter that is plugged into any standard electrical wall outlet. The power adapter provides interchangeable plug prongs to suit country-specific electrical wall sockets. EasyST can be managed by Airspan's AS.MAX Web-based management system using standard Web browsers, or alternatively, by an SNMP-based network management system (Netspan) through BS intervention using standard and proprietary MIBs. In addition, external third-party management systems such as HP OpenView can also manage the EasyST using these MIBs. 10 System Overview EasyST Frequency Ranges The table below lists the frequency range of EasyST models currently available.

14 System Overview Note: EasyST uses the antenna switch to select one of the four 90-degree antennas of the clip-on antenna. The antenna switch is not used in deployments in which the external window-mount antenna is implemented. EasyST Protocol Stack The figure below displays a block diagram of the EasyST's network architecture, designed as a hierarchy of protocols (i.e. protocol stack) implemented in the communication network. 15 605-0000-701 EasyST Hardware Installation User Guide Rev I Theory of Operation For basic operation, the EasyST requires no initial configuration--simply plug and play. Configuration is automatically performed over the air by the BS. The EasyST is preconfigured by the operator at the BS (using Netspan) with service flow parameters such as the maximum information rate, the committed information rate, the maximum latency, and maximum jitter. These configuration parameters are stored in Netspan's database corresponding to the EasyST's MAC address. Before any communication between EasyST and BS can occur, the EasyST must be positioned in a location that provides sufficient RF reception. To join a network, the EasyST needs to perform a few tasks. First, the "Network Entry" process

(defined in IEEE 802.16-2004) begins with the EasyST scanning for a downlink (DL) signal from the base station, and then synchronizing to the DL channel. Thereafter the EasyST can start the process of initial ranging, which alerts the BS to the presence of the EasyST and establishment of management connections to obtain basic, primary and secondary management connection IDs

(CID) from the BS. After the CIDs have been obtained, the EasyST commences authorization and key exchange. In the final stage, the EasyST registers at the base station and thereafter obtains the IP address, time of day and the configuration file from the BS. During Network entry, the EasyST sends the BS its MAC address. The BS via SNMP notifies Netspan of a new CPE connection and Netspan checks the database to it contains the CPE MAC address. The BS then accesses Netspan's database (via SNMP) and checks whether the EasyST's MAC address appears in the database. If it locates the MAC address, the Netspan feeds all the EasyST's configuration parameters (service flows) from the database and the BS downloads them to the EasyST device. 16 INSTALLATION PREREQUISITES Before installing your EasyST, read the following sections to ensure that no EasyST items are missing, minimum computer requirements are fulfilled, and you have the required installation tools.

o Horizontally on a desktop o Vertically on a wall Desktop Mounting The EasyST can be simply placed horizontally on a desk/table (as shown in the figure below). The EasyST radio provides integrated rubber feet (pads) on the bottom panel. These rubber feet provide cushioning as well as insulation from static electricity. Warning: To prevent a fire hazard caused by overheating, do not place the EasyST on a carpeted surface where airflow is restricted. Wall Mounting When EasyST implements the window-mount external antenna (i.e. no clip-on antenna), the EasyST can be mounted either on a desk (i.e. desktop mounting) or a wall. For mounting to a wall, the EasyST provides two mounting hooks molded into EasyST's bottom panel, as shown below:

28 Mounting Note: Before mounting the unit, ensure that the RF cable of the window-mount external antenna is plugged into the EasyST's MCX connector and that the cover cap is fitted onto the EasyST, protecting the MCX connector. To wall mount the EasyST:

1. On the wall, mark the position where you want to drill the two holes for the screws on to which the two mounting hooks will later by guided. The distance between the two wall-

mounting hooks (from their centers) is 83 mm (3.27 inches). Ensure that the holes are aligned and level using a spirit level. 2. Drill holes for each hole that you marked in the step above, using a no. 6 twist drill bit. 3. Insert the 6-mm wall anchors (supplied) into each of the drilled holes. 4. Drive the two 0.75-inch screws (supplied) into the wall anchors. Ensure that at least 0.08-

inch gap is exposed between the screw head and the wall anchor to allow insertion into the EasyST mounting hooks. 5. Align the entrance to the two EasyST mounting hooks with the screws, and then pull down the EasyST to lock the screws into the mounting hooks. 29 605-0000-701 EasyST Hardware Installation User Guide Rev I 30 OPTIMIZING RF RECEPTION To ensure a reliable, secure, and fast connection with your Internet Service Provider (ISP), you need to place your EasyST in a position that provides the best RF reception with the ISP (i.e. base station). To help you locate the best position, EasyST provides you with a LED indicator that indicates the strength of the RF signal with your ISP. This LED is labeled signal and is located on the EasyST's top panel. As the signal strength increases, so the signal LED line progresses to the right, as illustrated below:

Therefore, for optimal reception, simply move the EasyST to the position that lights up a longer signal LED line. 31 605-0000-701 EasyST Hardware Installation User Guide Rev I 32 Optimizing RF Reception The signal LED indicates the strength of the signal by measuring the signal-to-noise ratio (SNR). SNR indicates received signal strength relative to background noise. The ratio is usually measured in decibels (dB). Thus, the higher the SNR ratio, the better the communication. The table below describes the EasyST signal LEDs with regards to SNR values. LED Color Status Average SNR (dBm) signal Green All LEDs are off SNR < 5 First left-most LED is on 5 <= Avg. SNR < 9 Two left-most LEDs are on 9 <= Avg. SNR < 12 Three left-most LEDs are on 12 <= Avg. SNR < 16 Four left-most LEDs are on 16 <= Avg. SNR < 22 Five LEDs are on 22 <= Avg. SNR 33 CONNECTING THE EXTERNAL ANTENNA You can improve RF reception on EasyST by implementing a window-mount external antenna. This may be necessary in the following scenarios:

Subscriber's premises is located far from the base station, resulting in insufficient signal strength for viable communication link to occur when using the clip-on antenna. Location of mounted EasyST provides insufficient signal strength due to obstacles between the EasyST and ISP (i.e. AS.MAX base station) when using the clip-on antenna. EasyST provides an MCX connector for attaching the window-mount, external antenna's RF cable

(approximately 1.5 meters). The external antenna can then be easily mounted in a vertical position on a window using adhesive pads. The connection of the external antenna to the EasyST is performed in two main steps:

Attaching the antenna's RF cable to the EasyST Mounting the external antenna to a window For a detailed list of the specifications of the external antenna, see Window-Mount Antenna Specifications. Attaching the Antenna RF Cable Warning: Before connecting the external antenna, ensure that the EasyST is NOT connected to the power source. Do not connect and disconnect antennas while the power is on. This can cause irreversible damage to the device. To attach the external antenna's RF cable to the EasyST:

1. If you had originally ordered the EasyST with a clip-on antenna, then you need to remove it; otherwise, skip to Step 2. Remove the clip-on antenna by holding down on the EasyST with one hand, and then with the other hand, lifting the clip-on antenna up and away from the EasyST. 34 Connecting the External Antenna Warning: Do not rotate the clip-on antenna until it has detached entirely from the EasyST. 2. Remove the plastic protector cap to expose the MCX female connector. Insert a flat-head screw driver (or any tool with a blunt, pointed edge), into the cable groove created by the cap and the EasyST, and then gently leverage the cap's guides out of the EasyST's cover pins. 3. Plug the external antenna's MCX connector into the EasyST's MCX female connector, as shown below. 35 605-0000-701 EasyST Hardware Installation User Guide Rev I 4. Feed the RF cable into the EasyST's RF cable groove, ensuring that the RF cable exits the EasyST through the EasyST's RF cable groove, as shown above. 5. Protect the connectors by covering the area exposed by the removal of the clip-on antenna, with the plastic protector cap (supplied). Attach the plastic protector cap to the exposed area, by aligning the cap's two position cups with the EasyST's two position pins. Ensure that the cap's RF cable groove is aligned and flush with the RF cable and EasyST's RF cable groove. Note: If you later decide to disconnect the external antenna and reconnect the clip-on antenna, see Replacing the Clip-On Antenna. 36 Connecting the External Antenna Mounting the External Antenna The external antenna can be easily mounted in a vertical position on a window using the adhesive pads located on the side and front panels of the antenna. The antenna can be mounted in one of two orientations:

Antenna's front panel (narrow edge) is mounted flat against the window (typical orientation) Antenna's side panel is mounted flat against the window Note: The external antenna must be mounted on a flat, smooth, dry, and clean surface

(i.e. window). To window-mount the external antenna:

1. Locate the desired position on the inside of a window to where you want to mount the antenna. 2. Remove the white tape from the adhesive pads. Do not touch the adhesive surfaces. 3. Align the antenna vertically just above the window surface to where you want to mount the antenna, in the desired orientation (as described above). 4. Press the antenna down firmly onto the window surface so that all adhesive pads touch at the same time. Put pressure on all the areas under which are located adhesive pads. 37 605-0000-701 EasyST Hardware Installation User Guide Rev I Mounting antenna on its front panel:

38 Mounting antenna on its side panel:

Connecting the External Antenna Note: When mounted on its side panel, some loss in gain may be incurred. The figure below displays the antenna mounted on a window using the antenna's side panel. 39 REPLACING THE CLIP-ON ANTENNA The EasyST is supplied with the clip-on antenna already attached to the EasyST. However, in cases where you may have previously removed it to connect EasyST to an external window-mount antenna, you may want to discontinue using the external antenna and replace it with the clip-on antenna. Warning: Before disconnecting the external antenna and replacing the clip-on antenna, ensure that the EasyST is not connected to the power source. Do not connect and disconnect antennas while the power is on. This can cause irreversible damage to the EasyST. Note: Later EasyST models provide a screw for securing the clip-on antenna to the EasyST. To replace the clip-on antenna:

1. Remove the plastic protection cap protecting the antenna connectors, by inserting a flat-

head screw driver between the cap and the EasyST, and then gently leveraging the cap's guides out of the EasyST's cover pins. 2. Unplug the external antenna's MCX connector from the EasyST's MCX jack. 3. Align the clip-on antenna's knob with the EasyST's notch, as shown in the figure below. 40 Replacing the Clip-On Antenna 4. Gently push the antenna down onto the EasyST so that the MCX and 6-pin connectors plug into their respective receptacles, and that the antenna's knob sits firmly into the EasyST's notch. 5. For customers possessing EasyST models that implement a screw mechanism for securing the antenna to the EasyST, continue with the following steps:

a. Flip the EasyST over so that its rear panel is visible. Insert the M3 25-mm flat-head Philips screw (supplied) into the hole that's located on the rear panel, behind the RJ-45 and DC power connectors, as shown in the figure below. 41 605-0000-701 EasyST Hardware Installation User Guide Rev I b. Using a Philips screwdriver, tighten the screw so that the antenna is firmly attached to the EasyST. 42 EASYST SMART CARD The EasyST has an integrated Smart Card (SIM) terminal, which can utilize the optional EasyST Smart Card (sold separately). Contact your Airspan supplier for more information. The EasyST is fully functional with or without the EasyST Smart Card. When the EasyST Smart Card is inserted the EasyST uses the parameters set in the card (overriding the NVRAM parameter settings). Otherwise it uses the parameters set in the EasyST's NVRAM. Currently the Smart Cards are available from Airspan and are configured to your specific requirements. Note: In the event the Smart Card is removed the EasyST continues to function using SIM parameters, until the next reset when it utilizes the default stored NVRAM settings. The following defines the EasyST Smart Card stored parameters:

Operator ID - defines the Operator ID by means of the BS ID and Mask in order to enforce the CPE to be associated to a specific BS or to a group of BSs. This prevents the CPE from connecting to other BS(s) that do not belong to this specific operator RF Channel Scanning Table - determines the channel scanning range, when there are RF channel shifts in the table. This is performed during network entry, to find the best RF channel with the best reception level Maximum Tx Power - defines the maximum Tx power, to meet the regulations of the region 43 RESETTING EASYST TO DEFAULT SETTINGS The EasyST allows you to apply factory default configuration settings to the EasyST. This is performed by pressing the LED button (located below the LED lights on the top panel) continuously for at least 10 seconds. 44 TROUBLESHOOTING Once you have connected the EasyST to the subscriber's LAN and to the power supply, you can verify whether you have cabled the EasyST correctly by checking the EasyST LED status:

Connection LED Color Correct Status Troubleshooting Power power Red On If the power LED is off, recheck the power cabling and that power exists at the wall socket. LAN lan GreenOn If the lan LED is off, recheck the LAN cabling; ensure that you have connected it to the correct LAN port on your PC and that your network connection on your PC is enabled. 45 TRADEMARKS AND COPYRIGHTS 1.

Telephone (44) 1 895 467450. 1.8 Lightning Protection WARNING: The following notes are general recommendations for the system. The wireless equipment should be installed by a qualified professional installer and must follow local and national codes for electrical grounding and safety. Failure to meet safety requirements and/or use of non-standard practices and procedures could result in personal injury and damage to equipment. A direct lightning strike may cause serious damage even if these guidelines are followed. All outdoor wireless equipment is susceptible to lightning damage from a direct hit or induced current from a near strike. Lightning protection and grounding practices in local and national electrical codes serve to minimize equipment damage, service outages, and serious injury. Reasons for lightning damage are summarized as:

- Poorly grounded tower/antenna sites that can conduct high lightning strike energy into equipment.

- Lack of properly installed lightning protection equipment that can cause equipment failures from lightning induced currents. A lighting protection system provides a means by which the energy may enter earth without passing through and damaging parts of a structure. A lightning protection system does not prevent lightning from striking; it provides a means for controlling it and preventing damage by providing a low resistance path for the discharge of energy to travel safely to ground. Improperly grounded connections are also a source of noise that can cause sensitive equipment to malfunction. A good tower grounding system disperses most of the surge energy from a tower strike away from the building and equipment. The remaining energy on the RF cable shield and center conductor can be directed safely to ground by using a lightning arrestor in series with the RF cable. To limit the equipment damage due to a lightning strike, the following practices are recommended for the wireless system:

- Provide direct grounding from the antenna mounting bracket, the radio and antenna and the lightning arrestors to the same ground point at the base of the tower or a ground bus on the building. Use the grounding screws on the antenna bracket and the radio and antenna for terminating the ground wires. 52 Warnings and Cautions

- Install one RF lightning protector between the radio and antenna in series with the RF cable.

- A lightning arrestor in series with the RF cable at the point of entry to the building.

- Install a lightning arrestor in series with the IF cable at the transceiver on the tower/mast.

- The AC wall outlet ground for the MacroMAX terminal must be connected to the same grounding system as the radio and antenna lightning protectors. 53 GLOSSARY BS: Base Station BWA: Broadband Wireless Access B C CID: Connection IDs CPE: Customer Premises Equipment (interchangeable with ST) D dB: Decibel dBm: Power ratio in dB (decibel) of the measured power referenced to one milliwatt DL: Downlink FDD: Frequency Division Duplex FEC: Forward Error Correction GHz: Gigahertz H-FDD: Half-Duplex FDD IAD: Integrated Access Device IP: Internet Protocol ISP: Internet Service Provider LAN: Local-Area Network F G H I L M MAC: Media Access Controller.
