2.3 Indoor Antenna (s) Installation.
From preliminary evaluation of the blueprints of the service area, the approximate
locations of the indoor antennas must be established. The level of the signal at the
boundary of the service area can be a guideline for the location of the antennas. Several
parameters must be considered:
a) The gain of the Omni antenna is 0 dBd.
b) The free space propagation loss is approximately -60 dB per 100 ft.
c) The acceptable level at the lowest signal position for the mobile is -80 dBm.
Following the installation instructions mount antennas on the ceiling tiles or any other
appropriate location. Run the cables from antennas to the BDA location. Use a power
combiner, if needed, to interconnect the antenna cables.
CAUTION: Maximum Antenna gain shall be 15dBi.
A minimum separation distance of 65 centimeters
between the transmit antenna and nearby persons
must be maintained. If this separation distance is
not maintained, the device may not be in compliance
with FCC RF Exposure rules.
2.4 BDA Installation
The bi-directional amplifier can be installed as a freestanding unit lying on the shelf of a
cabinet or any other adequately strong support. It can also be secured by screws to the
wall or rack using four holes in the tabs located at the back plate of the enclosure. AC
power must be available in the vicinity of the BDA. It is recommended that the
environmental temperature will not exceed 50 C and the area will be adequately
ventilated.
Once amplifier is installed in place, open the front door and verify that all internal parts
are securely mounted. Connect the ground wire to the ground stud on the enclosure.
Plug in the AC cable into the AC socket. The green light on the enclosure must be lit on.
a) Downlink Gain Setting.
Connect the cable from the lightning protector and “DONOR” antenna to the “DONOR”
port of the BDA.
Connect a power meter or spectrum analyzer to the "SERVICE" port (Uplink input
connector) of the BDA. Measure the power of the signal at the “SERVICE” port of the
BDA.
The Power level should not exceed the maximum FCC power rating of the BDA for
the type of signal being amplified.
These power levels will guarantee the intermodulation products below -13 dBm, which is
in compliance with FCC regulation. After the output power level is set correctly, connect
the donor antenna cable to the "DONOR" port of the BDA.
b) Uplink Gain Setting.
Connect the indoor (service area) antenna cable to the "SERVICE" port of the BDA.
Initiate the call from the closest position of the mobile to the service area antenna.
Observe the yellow "Uplink AGC ON" light on BDA enclosure. The threshold of the
