<p>A wireless communication system comprises a central station which has base station controller function and at least one access device controlled by the central station. The central station and the access devices are connected by wire; the access devices are used for demodulating the wire signal sent from the central station to a radio signal and sending the radio signal to the target wireless user, then modulating the uplink radio signal sent by the wireless user to a wire signal and sending it to the central station. The central station is used for implementing baseband processing, intermediate frequency processing and radio frequency processing on the data provided by the core network, and obtaining radio signals and modulating said radio signals to wire signals, then sending said wire signals to the access device corresponding to the target wireless user of the data; then demodulating the wire signal sent from the access device to a radio signal and implementing radio frequency processing, intermediate frequency processing and baseband processing on this radio signal; then obtaining the data sent from the wireless user and providing the data to the core network. There are also a central station, a base station and two communication methods.</p> |
