Abstract

A main station (M) and subsidiary stations (S1) each have transmitter-receiver devices (TRDs). Each subsidiary station attempts to transmit data directly to the main station via a radio link. Any interference in direct radio transmission between the main station and one of the subsidiary stations affects the transmission/reception properties of antennas (1-3) for the TRDs of the main station or the subsidiary station not reaching the main station.
