British Telecom forges agreement to roam its customers onto Airpath hot spots: Following on the heels of Airpath's Sprint PCS partnership, BT will allow its customers to start roaming while traveling in the US onto the Airpath network. Airpath currently claims 350 hot spot locations, but they have 1,500 hot spot devices shipped. Of the 1,150 not-yet-active nodes, 900 will be flipped on soon, the company confirmed in email with me. The press release has Airpath predicting 4,600 locations within a year. Airpath sells its solution to individual ISPs or locations and handles billing and authentication for them.
BT subscribers can already roam onto TeliaSonera's partner network across Europe, which has nearly 700 locations. BT itself has only unwired a few hundred, but with TeliaSonera and Airpath, they now claim over 1,700 locations worldwide.
TeliaSonera's roaming generally involves cross-network fees, and I'm assuming that because the Airpath/BT press release doesn't discuss fees that there actually are roaming charges. Companies are careful to state when roaming is free.
