RBS 2106 and RBS 2206Radio Configurations
([WHUQDO 'XSOH[ )LOWHU
If an external duplex filter is used, it is possible to expand the configuration in
two steps. The first step does not require any new antennas, but limits the
number of GSM TRXs to two (that is, one dTRU) for each sector. Support of
more GSM TRXs requires additional antennas.
