A wireless system comprising a network of base stations (1) for receiving uplink signals transmitted from a plurality of remote terminals and for transmitting downlink signals to the remote terminals using a plurality of channels including a plurality of antenna elements (19) at each base station for receiving uplink signals, a plurality of antenna elements (18) at each base station for transmitting downlink signals, a signal processor (13) at each base station connected to the receiving antenna elements (19) and to the transmitting antenna elements (18) for determining spatio-temporal multiplexing and demultiplexing functions for each remote antenna for each channel, and a multiple base station network controller for optimizing network performance, whereby communication between the base stations and the remote terminals in each channel can occur simultaneously.
