T-Mobile's Hotspot@Home can be labelled as pre-femtocell service. Its based on UMA and needs UMA based phones for this service to work.The following is from a report in C-net:
Subscribers will be able to connect any regular home telephone to a T-Mobile router that will send calls over the Internet much the same way as services like Vonage operate. The service costs $10 a month plus taxes and fees for unlimited domestic local and long-distance calls.
Only T-Mobile wireless customers who subscribe to at least a $39.99 individual calling plan or families subscribing to at least the $49.99 monthly T-Mobile calling plan can get the service. The @Home service also requires that users subscribe to a separate broadband service from a cable operator or telecom provider. And they are required to use a special T-Mobile router, which also provides Wi-Fi Internet access throughout the home.
This router can also be used to provide T-Mobile's HotSpot @Home phone service. This service, launched last year, allows T-Mobile subscribers to use dual-mode cellular and Wi-Fi phones that switch between both networks. When subscribers are near their home Wi-Fi hot spot, they use the broadband network to make unlimited domestic calls. And when they are outside the home, the phone seamlessly switches to T-Mobile's cellular network.
The service, which also costs $10 extra per month, serves two purposes. It helps provide better in-home cell phone coverage and also helps reduce the number of minutes used on the T-Mobile cellular network.
