More than 100,000 UK broadband users have signed up to BT Fon, which allows subscribers to share wireless connections with other users.
The scheme works by opening home wireless connections to other Fon users who are in the area. In return, subscribers can access the internet on other people's connections around the UK and the rest of the world.
BT and its partner Fon recently received the Most Innovative Wireless Broadband Company accolade at the 2008 Wireless Broadband Innovation Awards for their work on the project, which is described as the largest wireless community in the world.
Jon Hurry, director of internet services at BT Consumer, said: "It's great to see BT Total Broadband customers joining forces to set up a people's Wi-Fi network across the UK."
He added that while BT Openzone and the Wireless City projects had already resulted in extensive wireless coverage, the popularity of BT Fon would serve to make access throughout the country "better and better".
Users of the service can use an online map to find hotspots throughout the UK and the rest of the world via the BT Fon website.
