6.3.1 Description
The Antenna Unit (AU) is the part of the BS that contains the eight radiating antenna elements, the heat
exchanger, calibration board, external thermal sensor and optional channel filters. (These filters are
installed on the outside rear of the AU.) An AU (refer to Figure 6-6) radiates over a sector of 90° or 120°,
configured during commissioning.

P R E L I M I N A RY
6.3.1.1 Channel Filters
In 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 Cable
Connect 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.

6.3.3 Handling the BWX 8415 Basestation
It is a good idea to inspect the exterior of the AU for any damage that may have occurred during shipping,
prior to placing it at the target site. 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.

6.3.5 Antenna Separation
When installing multiple BSs in the same geographical area, it is important to allow enough separation
so that they do not interfere with one another. Figure 6-12 provides some general guidelines for avoiding
adjacent interference. The illustration shows the horizontal and vertical separation in feet and in meters
for panel antennas.

Caution
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.
