5.9.5. Dual Antenna Receive Diversity

For specific BSR models (refer to the ASWipLL System Description book), two

antennas (integrated or external) are provided for antenna receive diversity at the

ASWipLL Base Station. This allows the BSR to select the antenna providing the

best RF reception to receive the signal.

For BSR models without integrated antennas, dual diversity is provided by the

existence of two N-type connectors for attaching two external antennas.

Notes:

1) The BSR with two antennas transmits using only one of the antennas

(factory selected).

2) Antennas must be orientated to cover the same area/cell (i.e. subscriber

sites), from only a slightly different location.
