02030311-07 Airspan Networks Inc. 5-1 Radio Site PlanningRadio Site PlanningRadio Site PlanningRadio Site Planning Proper site selection and planning before installing your ASWipLL devices will ensure a successful deployment of your ASWipLL system. Site planning includes the following considerations: ! Minimum obstructions (e.g. buildings) in the radio path between Base Station radio (i.e. BSR) and subscriber radios (i.e. SPR/IDR). ! Minimum incursions on Fresnel Zone (recommended minimum of 60% clearance of first Fresnel Zone). ! Mount radios as high as possible to avoid obstructions in the wireless path. ! Check possibility of future obstructions such as plans to erect buildings and trees that may grow tall enough to obstruct the wireless path. ! Align antennas for maximizing received signal strength (RSS) ! Consider nearby sources of interference that could degrade performance of radio. Mount radios as far from sources of interference as possible ! Ensure Base Station radio and subscriber premise's radio are within maximum coverage range of reception ! Maximum CAT-5 cable length connecting the outdoor radio to the indoor terminating equipment (i.e. switch/hub) is 100 meters ! Ensure that you have sufficient wiring conduit and cable ties to channel and protect the CAT 5 cable connecting the outdoor radio to the indoor hub/switch. ! Ensure required power mains outlet is available at the site. 5
Radio Site Planning Hardware Installation Guide 5-2 Airspan Networks Inc. 02030311-07 5.1. Minimal Radio Path Obstructions ASWipLL radios communicate by propagation of waves. Thus, ensure minimum obstructions (from, e.g. buildings and trees) in the radio path between Base Station radio (i.e. BSR) and subscriber radios (i.e. SPR/IDR). It is essential that the ASWipLL radios or antennas be installed in such a way that their radio paths have a clear path with each other. 5.2. Fresnel Zone Clearance There must be sufficient open space around the radio path to minimize interference with the radio beam. A minimum of 60% of the first Fresnel Zone of the path should be clear of obstructions. Despite a clear line-of-site, objects close enough to the transmission path may cause attenuation in signal strength and an increase in signal interference. Objects with reflective surfaces that seem relatively far away, but yet still encroaching on Fresnel Zone, may cause these interferences. Figure 5-1: At least 60% of first Fresznel Zone should be clear Fresnel Zones define the amount of clearance required from obstacles. These zones are composed of concentric ellipsoid areas surrounding the straight-line path
Hardware Installation Guide Radio Site Planning 02030311-07 Airspan Networks Inc. 5-3 between two antennas. Thus, the zone affects objects to the side of the path and those directly in the path. The first Fresnel Zone is the surface containing every point for which the distance from the transmitter to any reflection point on the surface point and then onto the receiver is one-half wavelength longer than the direct signal path. For calculating Fresnel Zone, refer to the ASWipLL System Description. 5.3. Multipath Fading Some of the transmitted signals may be reflected from a nearby building, by water under the signal path, or from any other reflectors. This reflected ("bounced") signal can then be received by the radio receiving the signal and superimposed on the main received signal, thereby degrading the signal strength. To avoid multipath fading from nearby buildings etc., Airspan recommends installing the outdoor radios at the rear end of the buildings instead of at the front. When you install at the rear end of the building, the front-end of the building blocks incoming signals from multipath reflections. Figure 5-2: Radios mounted at rear, blocking multipath reflection
Radio Site Planning Hardware Installation Guide 5-4 Airspan Networks Inc. 02030311-07 5.4. Spectrum Analysis for Locating Clear Frequencies Before setting up your wireless link between Base Station and subscribers, Airspan recommends (especially in unlicensed bands), analyzing the RF spectrum at the Base Station to select only clear frequency channels (i.e. without interferences) for building a frequency table for wireless communication between Base Station and subscriber. Prior to performing this test, you need to mount the radio/antenna in the desired installation spot. In general, you will be looking for frequencies with signal strengths of –85 dBm or greater. For using Airspan's spectrum analyzer tool, refer to the WipConfig User's Guide. For evaluating link quality using the Spectrum Analyzer, see Appendix E, "Evaluating Link Quality". 5.5. Adjacent Base Station Radios For installations involving co-location of BSRs, it is important to assign frequencies of maximum spacing. This is to reduce possible radio interference between adjacently installed BSRs. In addition, a 1-meter separation must exist between adjacent BSRs. 5.6. Radio Antenna Alignment Once the subscriber unit (i.e. SPR/IDR) is installed and aimed in the general direction of the BSR, it is recommended to measure the received signal strength (RSS) to determine the signal strength received from the BSR, and to precisely align the SPR/IDR for maximum signal strength. You need to orientate (up/down, left/right) the SPR/IDR until the maximum RSSI levels are achieved, and then secure the SPR/IDR. For short links you can expect an RSSI of –60 dBm or better. For longer links, an RSSI of –75 dBm is acceptable. Any RSSI of less than –80 dBm may be too weak for the radios to reliably communicate.
Hardware Installation Guide Radio Site Planning 02030311-07 Airspan Networks Inc. 5-5 Airspan offers various tools for measuring RSS (check with your Airspan representative regarding cost and supply): ! SPR: ! RSS LED adapter (see Part II, Chapter 17, "Antenna Alignment using RSS LED Adapter") ! WipConfig program (see Appendix E, "Evaluating Link Quality") ! IDR: built-in RSSI LEDs (see Part III, Chapter 24, " Antenna Alignment Using RSS LEDs") 5.7. Considerations when Using External Antennas Notes: 1) To avoid unnecessary RF cable loss, use short-length cables and with low attenuation. 2) Antennas should have a VSWR of less than 1:1.5. 3) Ensure BSR and SPR/IDR use the same antenna polarity. 4) When using an omni-directional antenna, choose a type providing a wide vertical beam width (of at least 8°) to allow connection of closer CPEs. 5) Antenna must be DC grounded. 5.7.1. Cable Loss Airspan’s ASWipLL radios provide transmit power compensation for power attenuation caused by cable loss (in cable connecting to external antenna). Cable loss is the loss of radio transmit (Tx) power as heat, and directly proportional to cable length and quality, and operating frequency.
Radio Site Planning Hardware Installation Guide 5-6 Airspan Networks Inc. 02030311-07 To adhere to EIRP limitations in the regulatory domain in which you are operating your ASWipLL system, when purchasing antenna cables take into consideration cable loss per cable length. EIRP is calculated using cable loss (i.e. EIRP = max. power output + antenna gain - cable loss). For example, FCC regulations state that when operating in unlicensed bands, the external antennas must provide an EIRP of less than or equal to 36 dBm to prevent interference with other radios. Thus, knowing this EIRP parameter, you can choose the cable that ensures adherence to this parameter value. The table below lists examples of cable loss per cable length. Table 5-1: Examples of cable loss per cable length Note: Airspan does not supply external antenna cables. It is the responsibility of the installer to provide the cable and ensure the cable characteristics (e.g. length and cable loss) enables adherence to EIRP regulations of the country or area in which the ASWipLL system is operating.
Hardware Installation Guide Radio Site Planning 02030311-07 Airspan Networks Inc. 5-7 5.7.2. Omni-Directional Antennas In some scenarios, where capacity demand is relatively low, external omni-directional antenna use at the Base Station may seem attractive. However, it is recommended to avoid using omni-directional antennas (if possible), due to the following disadvantages that these antennas pose compared to directional antennas: ! Higher sensitivity to external interferences. ! Higher sensitivity to multipath, resulting in the following: ! The root mean square (RMS) delay spread at the Base Station is substantially higher. ! Multipath interference at the CPE side (when using omni-directional antenna at the Base Station) is substantially higher. In fact, when using an omni-directional antenna, the existence of clear Fresnel zone between BSR and SPR/IDR is insufficient to eliminate multipath interference, since multipath, in this case, can be caused by reflections originating from obstacles outside the Fresnel zone. ! Higher sensitivity to alignment. Since the omni-directional antenna gain is achieved by narrowing the vertical beam width, a relatively low deviation in the antenna alignment will result in severe signal attenuation.
Radio Site Planning Hardware Installation Guide 5-8 Airspan Networks Inc. 02030311-07 5.7.3. Operating in Band-C for FCC Markets Some operators (e.g. in the USA) have licenses for Band-C (710 – 716 MHz and 740 – 746 MHz). ASWipLL 700 provides an external antenna, allowing coverage in the entire 700 MHz band (698 to 746 MHz), including the licensed A and B bands used in USA. A maximum of four BSRs operating in Band-C are allowed at a Base Station (in accordance with FCC regulations). This regulation ensures minimum RF interference with other radio devices that may be operating in nearby frequencies. In the 1 Megasymbols per second (Msps) mode, the center frequencies are 711.5, 712.5, 713.5, 714.5, 741.5, 742.5, 743.5, and 744.5. Thus, the frequency allocation for four BSRs is 711.5, 741.5, 714.5, and 744.5. In the 1.33 Msps mode, the center frequencies are 712, 713, 714, 742, 743, and 744. Thus, the frequency allocation for four BSRs is 712, 742, 714, and 744. Figure 5-3: Frequency allocation in a four-sector Base Station Radio interference may occur between the BSRs operating in the upper frequency range (i.e. 742 MHz and 744 MHz) and the lower frequency range (i.e. 712 MHz and 714 MHz). To overcome this interference, a 1-meter vertical separation is recommended between the BSRs operating in the upper frequency and the BSRs operating in the lower frequency.

Pole-Mounting the BSR The BSR is typically mounted on a pole, however, it can be wall mounted as well. Pole mounting allows the BSR to be easily adjusted in the horizontal (azimuth) and vertical (elevation) planes for antenna alignment. Note: In the standard BSR kit, Airspan does not supply wall-mounting brackets. To order wall-mounting brackets, contact your Airspan representative. BSR wall mounting is identical to SPR wall mounting.Therefore, for a detailed description of wall mounting, see SPR wall mountingin Part II, Chapter 13, "Mounting the Devices". The BSR is mounted using the mounting holes located on the BSR’s bottom panel (see Figure 7-1) and the supplied pole-mounting brackets. The pole-mounting bracket is designed to support the BSR on a round pole of 45 mm in diameter. 7

Rack Mounting the BSDU The BSDU is designed for mounting in a standard 19-inch (48.3 cm) equipment rack or telco rack with 1 rack unit (1-U) of vertical rack space. The sides of the BSDU chassis provide integrated front-rail mounting brackets. Therefore, all that is required for mounting the BSDU is to attach the BSDU front-rail mounting brackets to the rack. The mounting brackets are secured to the rack's mounting rails using the supplied four M5 mounting screws and plastic cup washers. To rack-mount the BSDU: 1. Determine which rack rail holes—left and right side—will be used for attaching the chassis. 2. Insert four nuts into the rack's rail holes you designated in Step 1. These nuts are housed in Tinnerman clips, which allow you to fasten them into the rail holes. To insert the Tinnerman clips, hold the clips, squeeze them, and then insert them into the rail hole. 3. Carefully insert the BSDU into the rack, aligning the BSDU’s mounting bracket holes with the rack rail holes. 4. Insert the M5-mounting screws, with plastic washers, into the BSDU mounting bracket holes, on each side, as shown in Figure 7-10. In this way, the chassis is supported until you tighten the chassis screws. 5. Tighten the M5 mounting screws to fasten the chassis to the cabinet.

The implementation of these antennas depends on the BSR model (with respect to radio antennas) and the need for synchronization of the ASWipLL system (with respect to GPS antennas). 10.1. Connecting Radio Antennas to BSR The BSR model without a built-in radio antenna provides an N-type port(s) for connecting a third-party external antenna(s). The BSR models for the 900 MHz and 700 MHz bands provide two N-type connectors for connecting two third-party external antennas. Two antennas provide dual-antenna diversity, whereby data is transmitted using only the main antenna, while data is received by the antenna (main or secondary) with the best radio frequency (RF) reception. Warning: It is the responsibility of the person installing the ASWipLL systemto ensure that when using the outdoor antenna kits in the United States (or where FCC rules apply), that only those antennas certified with the product areused. The use of any antenna other than those certified with the product isexpressly forbidden in accordance with FCC rules CFR47 part 15.204.

Warning: In accordance with FCC regulations, ensure that when operating in unlicensed bands, the external antennas provide a maximum EIRP of 36 dBm to prevent interference with other radios operating in the unlicensed band. The EIRP is defined as: Max. Power Output + Antenna Gain + Cable Loss ≤≤≤≤ 36 dBm (EIRP) The following lists the BSR-to-third party external antenna cable setup: ! Cable (third party): RF coaxial ! Connector (third party): N-type male. The usage of N-type ports for models (i.e. in 700 MHz and 900 MHz bands) with two N-type ports: ! If you are using only one antenna, connect the antenna to the N-type port labeled Primary. ! If you are using two antennas, connect the second antenna to the N-type port labeled Secondary. Warnings: 1) Before connecting the external antenna, ensure that the BSR is NOT connected to the power source. 2) Before powering on the BSR, ensure that some type of equipment such as an antenna or an RF attenuator is connected to the N-type port. This eliminates the risk of damaging the BSR device.
