5.8.5. Dual Antenna Receive Diversity
For BSRs operating in the 700 MHz or 900 MHz bands, two antennas 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.
In this operating band, for BSR models with integral antennas, two internal, built-in
antennas are provided. For BSR models without built-in, internal 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.
