摘要
A digital TDMA/FDMA (Time Division Multiple Access/Frequency division Multiple Access) cellular network system, suitable for a microcellular network and to maximize the advantage to be gained from interference diversity, including base stations forming radio cells, each having a determined static frequency of a channel of the cell and including a first transceiver continuously transmitting control data of the system concerning the cell at the control channel frequency, at least in one predetermined time slot of a TDMA frame. The TDMA frame of the first transceiver includes traffic channels at least in a part of the other time slots. Each base station further includes at least one second transceiver for the traffic channels. The system further includes mobile stations connected to the base stations via a radio path. The traffic channels of the second transceiver units use frequency-hopping, at least in a part of the radio cells, in such a way that, on those traffic channels aligned with the predetermined time slots of the control data of the cell in the first transceiver, substantially all frequencies of the available frequency band, except the control data transmission frequency determined for the cell, belong to the hopping sequence. On those traffic channels which are in the other time slots, substantially all frequencies of the available frequency band belong to the hopping sequence.
