•

dedicated mode, that is, the FHCC is directly connected to the operators’ repeater system only.

•

coupling sector mode. In this mode FHCC is connected to both, operators’ repeater system and RF Modules. The repeater system shares the same I/Q data with RF Modules in downlink. The uplink I/Q data are diversity summed, path by path in the RIM.
