The method involves transmitting a test channel between each subscriber station (T111,..,T222) and transceiver unit of those sectors (S11,..,S22) which can cause interference at a corresponding subscriber station. The attenuation for each signal path between the subscriber stations and the sectors is determined using the transmission and reception power of the test channel. A carrier signal-to-noise ratio is determined for each subscriber station. The modulation of a data signal transmitted between a subscriber station and a corresponding sector is changed to a stronger modulation type when the carrier signal-to-noise ratio is below a preset threshold (S1). At least one sector which causes the largest interference for the corresponding subscriber station is switched to a different frequency channel. |
