PRELIMINARY6-7BWX 8415 Basestation Installation and Commissioning GuideOL-19519-01Chapter 6 Installation6.3.2 Install the GPS Antenna Cable6.3.1.1 Channel FiltersIn the BWX 8415 Basestation you have the option to: • 1 - Use a Channel filter: The functions of Channel filters are two-fold: (1) to shape the power amplifier out-of-band emission during transmission in order to meet FCC or other regulatory requirements; and (2) to provide high rejection for close-in jammers during the receive period. The latter improves receiver selectivity. As indicated by its name, the filter operates in a specific limited frequency band (e.g., Bandwidth (BW) = 5 to 20 MHz) and has more stringent attenuation requirements. Normally, the attenuation is 15-20 dB rejection for close-in frequencies. If a BWX 8415 Basestation has channel filters installed, it must be operated at a center frequency that exactly matches the center frequency for which the channel filters were manufactured; otherwise, the equipment could be damaged. • 2 - Not use a filter at all:If no channel filters are installed, the service provider is free to select or change the center frequency of the BS without damaging the equipment.Note Depending on the country where the system is being used, a channel filter may be required to meet the spectrum requirements of that region. A consideration to keep in mind when addressing a deployment for a specific region.If the channel filters do not come installed and you have to install them, please refer to Appendix E, “BWX 8415 Channel Filter Installation Procedure”, for the procedure to install the filters.Note If channel filters are required to be installed, after the BWX 8415 Basestation has been installed on the tower or building, the basestation will need to be lowered to the ground.6.3.2 Install the GPS Antenna CableConnect the GPS cable to the GPS antenna, located at the top of the BWX 8415 BS and tighten the connector to 12 to 15 in-lbs. (1.4 to 1.7 Nm). Refer to Figure 6-7.Note In the event that the BWX 8415 BS is mounted on the side of a building, the GPS antenna can be removed from the BS and mounted to a location where the antenna will have a clear 360° view of the sky. The GPS cable loss must be less than 8 dB.

Each of the antenna elements in the AU are covered by the individual radomes on the panel. At all times handle the antenna carefully. If, during storage, filter replacement, or RU replacement, you must place a panel antenna in a position laying down, make sure it rests flat on at least one inch of plastic foam to prevent damage to the antenna elements. When you are ready to place the antenna into position, it should be lifted using multiple lift points. Attach the hoisting cable to the AU’s lift points, as shown in Figure 6-8. Caution Never use the radomes to lift, support, or otherwise bear partial or full weight of the BWX 8415 Basestation. Doing so can cause damage to the radomes. Use two ground-anchor lines attached to the lower mounting bracket to steer the AU and prevent it from spinning or swaying in the wind and perhaps hitting the tower or other nearby structures with the radomes.

PRELIMINARY6-13BWX 8415 Basestation Installation and Commissioning GuideOL-19519-01Chapter 6 Installation6.3.5 Antenna SeparationCaution There can be no co-location of MC-SCDMA with Mobile WiMAX basestations. If 2 or more BSs are co-located on the same structure, they must run the same technology or be upgraded in the same maintenance window. Use frequency separation to minimize interference between a MC-SCDMA and Mobile WiMAX basestation. A reasonable frequency separation is 15 MHz for BSs that are 2 kilometers apart. The exact frequency separation may differ on a case-by-case basis. Therefore, 15 MHz with 2 kilometers between basestations may not provide enough separation. Refer to the BWX Mobile WiMAX Migration Planning Guide for more information on distance requirements.Caution All BSs in a network must have the same DL/UL symbol ratio. The default recommended ratio is 32/15. Cisco does not support basestations that use different DL/UL symbol ratios in the same area because they will interfere with each other. Please refer to the BWX EMS Configuration Guide for more information on parameter settings.Figure 6-12 General Separation GuidelinesHORIZONTAL SEPARATION (TOP VIEW)PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°VERTICAL SEPARATION(SIDE VIEW)Panel10 ft(3 m)PanelPanelPanelPanelPanelPanel-PanelHorizontal Vertical5 ft (1.5 m) 10 ft (3 m)HORIZONTAL SEPARATION (TOP VIEW)PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°VERTICAL SEPARATION(SIDE VIEW)Panel10 ft(3 m)PanelPanelPanelPanelPanelPanel-PanelHorizontal Vertical5 ft (1.5 m) 10 ft (3 m)HORIZONTAL SEPARATION (TOP VIEW)PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°HORIZONTAL SEPARATION (TOP VIEW)PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)PanelPanel PanelPanel PanelPanel 5 ft5 ft5 ft5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)(1.5 m)(1.5 m)(1.5 m)PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)Panel120°120°120°PanelPanelPanelPanel(1.5 m)(1.5 m)5 ft5 ft5 ft(1.5 m)(1.5 m)(1.5 m)5 ft5 ft5 ft5 ft5 ft5 ft(1.5 m)Panel120°120°120°120°120°120°VERTICAL SEPARATION(SIDE VIEW)Panel10 ft(3 m)PanelPanelPanelPanelPanelVERTICAL SEPARATION(SIDE VIEW)Panel10 ft(3 m)PanelPanelPanelPanelPanelVERTICAL SEPARATION(SIDE VIEW)Panel10 ft(3 m)PanelPanelPanelPanelPanelPanel10 ft(3 m)PanelPanelPanelPanelPanelPanel-PanelHorizontal Vertical5 ft (1.5 m) 10 ft (3 m)Panel-PanelPanel-PanelHorizontalHorizontal VerticalVertical5 ft (1.5 m)5 ft (1.5 m) 10 ft (3 m)10 ft (3 m)
