Cordless access over an extended area is provided by a network of co-operating wireless access points 10, 20, 30 etc all operating on a common channel, such that continuous communication with a mobile handset 9 is possible within the combined coverage of the set of access points. The access points are all recognised by the handset 9 as being part of the same connection. The access points are in communication with each other, either by wireless connections 11, 51 or by wired connections 21, 41, so that they can communicate between each other, a home base site controller 60, and a connection 31 to the public network. Under the control of the HBSC 60, all the access points 10, 20, broadcast a common service set identifier SSID and operate on the channel selected by the HBSC 60, and consequently a communications session can continue seamlessly, regardless of which access point is currently in use. The HBSC 60, on receiving a data transmission addressed to a specified handset 9, forwards it to any access points 20, 40 directly connected to it. A method is disclosed for setting up the access points 10, 20, 30 to form the wireless network.
