Two way cordless communications uses multichannel transceivers portable within a coverage area comprising cells, each associated with a base station and antennas, such as to permit channel frequency reuse in cells within the coverage area. For at least part of the coverage area, the locations of the antennas within the cells and the locations of the base stations are independently mapped, the antennas being associated with active antenna systems and the active antenna systems being connected to the base stations utilizing broadband transmission by means of a fixed bidirectional cable television network. The network is connected to the base stations and the antenna systems through interfaces incorporating frequency translation so that available frequency bands in the cable television network, which will normally be shared with other services, may be utilised.; Plural base stations may be co-located. The radio link to the transceivers may be FDM or TDM, but communication over the network will normally be frequency multiplexed, using separate bands for transmission and reception.
