Installing the BSR Hardware Installation Guide 4-2 Airspan Networks Ltd. 02030311-05 4.1. Overview The BSR is the center of the WipLL system. The BSR provides last-mile wireless connectivity by connecting the provider’s backhaul network to the subscriber’s wireless unit (Subscriber Premises Radio [SPR]). In addition, the BSR is responsible for synchronizing the WipLL network (i.e., synchronizing SPRs/IDRs). For base stations consisting of a single BSR, the BSR is typically powered and connected to the provider’s backhaul network by the WipLL Subscriber Data Adapter (SDA). For base stations consisting of multiple BSRs, the BSRs are powered and connected to the provider’s backhaul by the WipLL Base Station Distribution Unit (BSDU). The BSR is available in three models: ! BSR with a built-in antenna ! BSR with an N-type port for connection to an optional third-party external antenna ! BSR with an two N-type ports for connection to two optional third-party external antennas for dual antenna diversity

Installing the BSR Hardware Installation Guide 4-4 Airspan Networks Ltd. 02030311-05 4.3. Cable Installation Guidelines This section defines the procedures to be adhered to when installing data cables at the base station. Warning: Pre-terminated cables should be fitted with protective poly bags during cable installation processes. Metal cable trays shall be earthed to a central earth point within the customers’equipment room. Note: A minimum separation of 200 mm should exist between power and datacables. The following points are to be considered: ! When installing network cables, ensure they are not damaged by friction or sharp edges. Spacing of installation personnel at regular distances during any cable drawing-in process will avoid contact with potential hazards. ! Data cables providing connection to the customers network shall be run in suitable conduits. Cable conduits should be secured to the wall in accordance with manufacturers instructions. ! Cables should be carefully fed through conduits and not pulled by means of any attached connector. ! Sufficient space should be provided in cable ducts, trunking or trays (where possible) to allow for future cabling growth. ! External data cables are to be protected in protective conduit, which is to be secured to the building structure in accordance with manufacturers recommendations. Trunking must not be located as to provide a trip hazard at the base station premises (e.g. roof walkways) ! BSR cables are to be dressed tidily to the mounting pole or bracket using strategically placed cable ties.

Hardware Installation Guide Installing the BSR 02030311-05 Airspan Networks Ltd. 4-5 ! Observe recommended minimum bend radii when installing copper cables. Wherever a cable changes direction, ensure that it does so in a smooth curve with a radius of at least 50 mm to prevent damage. ! A maintenance loop is to be left in the cable just before the cable reaches the BSR or GPS to prevent strain on the connector. ! Data cables entering holes drilled in walls are to be dressed to provide a loop that will prevent water ingress into the building along the cable. ! Silicone sealant should be used to plug any holes on both internal and external wall surfaces once cables are in place. ! All data cables should be labeled with both the source and destination at each end. Note: The maximum cable length between the BSR and terminating equipment is 100 meters.

Installing the BSR Hardware Installation Guide 4-18 Airspan Networks Ltd. 02030311-05 4.6. Connecting a Third-Party External Antenna (Optional) The BSR model with an N-type connector can be connected to an external antenna. The addition of an external antenna allows greater RF sector coverage than the standard BSR Internal Antenna model (i.e., 60°). The BSR with an external antenna is especially suited for base stations with one BSR, where sector coverage can be increased to 360° by using an omni-antenna. The BSR model for the 900 MHz band provides two N-type connectors for attaching two external antennas. This provides dual antenna diversity. ! Connector (third-party): N-type male (two N-type connectors for BSR model for 900 MHz band. The N-type socket labelled Primary is used only if one antenna is connected.) Figure 4-9: Example of an N-type connector ! Cable (third-party): RF coaxial 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 equiment such as an antenna or an RF attenuator is connected to the N-type receptacle. This eliminates the risk of burning the BSR device. To connect the BSR to an external antenna: ! Attach the third-party N-type male connector to the N-type receptacle located on the BSR’s front panel, as displayed in Figure 4-10.

Hardware Installation Guide Installing the BSR 02030311-05 Airspan Networks Ltd. 4-19 Notes: 1) For crimping cables for N-type connectors, see Appendix B, “Cable Crimping”. 2) Ensure that the third-party antenna cable is of sufficient high quality to reduce/eliminate loss when operating in the required frequency band.

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