Line Of Sight; Figure 4-4 Line Of Sight To The Enode-B(Or Bts) - ADRF SDR-ICS-43 User Manual

WARNING: Inserting a CW signal into the SDR-ICS-43 when ICS is enabled will cause the system to generate a
false alarm. The false alarm will cause the system to go into a shutdown state. If a CW signal needs to be injected
into the repeater for testing purposes, the ICS routine must be turned off.

Line of Sight

The donor antenna which points towards the eNode-B typically has a narrow beam antenna pattern. As a
result, a slight deviation away from the direction of the eNode-B can lead to less than optimum results. In addition,
obstacles between the repeater and the eNode-B may impair the repeater from obtaining any eNode-B signal. As a
result, the repeater cannot transmit signal to the coverage area. Therefore, a direct line of sight to the eNode-B 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.
