SDR Installation

Installation Antenna Line of Sight
Donor/Server Antenna Line of Sight:
The donor antenna which points towards the base
station typically has a narrow beam antenna pattern.
Any slight deviation away from the direction of the
BTS can lead to less than optimum results.
Obstacles between the repeater and the BTS may
impair the repeater from obtaining any BTS signal. As a
result, the repeater cannot transmit signal to the
coverage area.
Therefore, a direct line of sight to the BTS for the
donor antenna is vital to the function of a repeater.
For the same reason, placing the server antenna in
direct line of sight of the coverage area is also
necessary.

Installation Antenna Setup
Antenna Separation/Isolation:
Separation between the antennas is necessary to
prevent oscillation, which can cause the noise level to
rise above the signal level.
Isolation is attained by separating antennas a
sufficient distance so that the output of one antenna
does not reach the input of the other.
REPEATER
A sufficient isolation value is 15 dB greater than the
maximum gain of the repeater.
The SDR has a maximum gain of 90 dB, thus it
requires an isolation of at least 105 dB.

Commissioning
If the isolation value between the donor antenna and server antenna is
available, then manually set the Downlink Gain use the following
formula:
Downlink Gain = Isolation Value 20dB
For example, if the measure isolation value is 100dB, then the DL
gain should not exceed 80dB to avoid oscillation
UL Gain can be set 3 dB below the DL Gain value
In this example, the UL gain would be set to 77dB
ADRF CONFIDENTIAL
67
Commissioning
If the isolation value is not available, set the DL and UL gains to the
minimum levels and then raise the gains in 5dB increments
Navigate to the Status tab and monitor your input and output levels for
major fluctuations
The fluctuations should not exceed the breathing levels for the
technology

Once the system is stable, navigate
to the Install tab and run the
Installation routine by clicking the
