We’ve written a lot about the Unlicensed Mobile Access group: But the IEEE has its own group that is working on a standard for roaming between cellular and Wi-Fi networks. The members of the groups come from different camps and thus have different priorities. It’s not clear if they’ll be able to merge their ultimate standards.
Members of the UMA tend to come from the cellular world, so they are concerned with having as much control as they can with when and how their customers roam onto Wi-Fi networks. The IEEE group comes from the Wi-Fi group, so they are looking for the solution to be as standards-based and open as possible. The two groups are of course aware of each other and are talking about trying to harmonize.
There’s a third group that is also working in this space, calling itself the Seamless Converged Communication Across Networks Group. It’s not clear how that group, which Motorola says is concerned with handoffs between corporate LANs and wide area cellular networks, will coexist with the others.
