T-Mobile today announced nationwide availability of its HotSpot@Home service. It uses special Wi-Fi equipped handsets to transfer voice calls to designated HotSpots when they are in range (at home). The service costs an extra $19.99 per month.
When calls are made over a WiFi network instead of a cellular network, they do not count against the subscriber’s monthly minutes, but there is a monthly flat fee. Two compatible phones, the Nokia 6086 and Samsung T409, are available for $50 with a two year contract.
T-Mobile is launching the service at a promotional rate of $10 per month for individuals and $20 for family plans. The rates will increase another $10 per month after the promotion has ended. A $50 access point will be free after rebate. The service was initially launched in Seattle.
UMA links your VoIP phone software with the cellular network, signaling T-Mobile when you’ve moved from cellular to WiFi. That allows calls to be routed automatically between the cell network and your current hotspot.
UMA needs special hardware on the phone side —- you can’t just use any Wi-Fi-enabled phone. But T-Mobile’s UMA-enabled phones should work on most any WiFi network — not just your own or T-Mobile’s.

Handsets that offer only Wi-Fi connectivity have been a failure, according to the U.K. director of home and office communications devices for Siemens. Most dedicated Wi-Fi phones can’t use the cellular network at all, so their utility is limited.
Taking another tack, Netgear is working with femtocell maker Ubiquisys on a 3G femtocell access point for the home. It will extend and repeat a cellular carrier’s signal into the home and support UMTS and HSPA (as well as Wi-Fi), so you can more easily use your plain vanilla cellphone inside the house.
It will be available for operator testing by Q4 2007, with commercial availability slated for early 2008.
