Wireless and fixed line operator Telia Denmark is planning to be the first to pilot a service which offers integrated mobile telephony and VoIP for residential customers. Telia intends to start trials this year to test the performance of a new integrated solution, which features a single handset that serves as an IP phone within a user’s house, and switches automatically to a mobile network upon the user leaving home. The technology will be based on the international unlicensed mobile access (UMA) standard which allows a mobile device to communicate over the internet via either Bluetooth or W-LAN protocols. The company’s Swedish parent, TeliaSonera, says it hopes evaluation of the new system will be complete by the end of this year, with a view to launch commercially in 2006.
