A new working group within the International Packet Communications Consortium was formed to work on roaming among wireless and wireline networks: One goal of the group is to facilitate handover between cellular and Wi-Fi/WiMax networks. It’s not totally clear to me how this group will co-exist next to the companies that are developing the Unlicensed Mobile Access technology. This new working group seems a bit broader in focus, also including the development of methods for roaming across DSL, cable, cellular, Wi-Fi, and WiMax networks.
Unless I’m missing something, “seamless roaming” between, for example, DSL and cellular, isn’t really possible. To me seamless implies that the user doesn’t do anything. But DSL requires users to be tethered to a wire. Perhaps “seamless roaming” in this sense has more to do with backend billing and customer management than handoffs.
