BT is already holding trials of its version of UMA, which uses Bluetooth to connect to the fixed line in the home and GSM outside. WiFi and GSM may be the main UMA technology but a combination of UltraWideband and WiMAX could come later.

Soon your phone may be able to switch smoothly from wireless networks outside to the broadband network inside your home. A number of companies are going after the potentially lucrative market of ``fixed-mobile'' convergence. Players include Kineto, Stoke, Newstep Networks, BridgePort Networks and Netmotion Wireless.
