Unlicensed Mobile Access: Seamless WiFi to cellular roaming

Ok, so we'll be the first to admit that maybe Voice over WiFi hasn't exactly taken over the world or brought the telcos to their knees. There are loads of reasons why, like that the first WiFi phones aren't that great or easy to use, cellphone minutes are already pretty cheap, and the fact that it's not really possible to automatically switch between cellular and WiFi when you're making a call or downloading something, but a bunch of the heavyhitters like Nokia, Motorola, Cingular, T-Mobile, Sony Ericsson, Siemens, and others are trying to change that. They're trying sort out a single standard called Unlicensed Mobile Access for seamlessly roaming back and forth between GSM cellular and WiFi networks.
