Orange, the mobile phone operator, has outlined plans to launch the UK's first broadband service that will work on both the mobile phone network and the fixed-line internet, depending on where customers are located when they connect. If customers access broadband at home, they will be connected to internet services through Wanadaoo, the internet service provider also owned by Orange's parent France Telecom.

Outside the home, the connection will be over Orange's high-speed third generation mobile network. Orange, which launched 3G services in the UK at the beginning of December - later than rival Vodafone - plans to use the service as a key way to differentiate itself in the fiercely competitive UK mobile phone market.
