Unlicensed radio to mobile network

Motorola just announced their own UMA/GAN product which they market as RSG (Residential Seamless Mobility Gateway). The Motorola RSG can seamlessly transfer voice calls between the home wireless network (WLAN) and the cellular network without interrupting the call, when paired with a dual-mode handset and connected to a network and service that supports this feature. Dual-mode handsets are mobile devices that can access both cellular and in-home wireless networks. There are two products in the Motorola RSG family: the RSG2500, expected availability Winter 2006, and the RSG3500, expected availability Summer 2006, which adds the ability to power two lines of primary VoIP telephone service within the home.
The Unlicensed Mobile Access (UMA) forum developed the idea to use unlicensed radio in a handset to access mobile network services. The forum’s specifications were released in September 2004, and UMA has now been included as a work item in the Third Generation Partnership Project (3GPP) under the name Generic Access to A and Gb Interface (GAAG). Within 3GPP, the UMA technology specification is called Generic Access Network (GAN). The GAN specifications have since been approved for inclusion in 3GPP release R6.
Earlier, Motorola announced availability of their A910 phone [pdf] (UMA/GAN capable) in this quarter.
