Installation Antenna Line of Sight

13

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

14

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.

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.

67

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

68

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
