Abstract
A method of two-way radiocommunication between fixed stations and mobile stations permitting effective utilization of available radiocommunication channels. All the fixed stations transmit in a first radio path of multiplexed communication channels and all the mobile stations transmit in a second radio path of multiplexed communication channels, each pair of communication channels in the first and second paths being capable of handling two-way communication between any one of the fixed stations and any one of the mobile stations. When the channels are time-division multiplexed, in accordance with the TDMA-type method, only two numerical paths are utilized. When the channels are frequency-division multiplexed, in accordance with the FDMA-type method, only two frequency bands are allocated to radiocommunications.
