They sure move quickly: The WiMax Global Roaming Alliance (WGRA) was formed only a few weeks ago, and its leading member, RemotePipes, is already pushing for the creation of a system which will make it possible for WiMax users to roam among different WISPs. The WGRA is not a standards-developing organization, but rather a lose fedration of companies interested in developing a consensus around the preferred emerging standard. The organization may offer modifications to these emerging standards, but the emphasis will be on urging a uniform deployment and implementation of the standards.

As Eric Engbers, president of RemotePipes, said, "There is nothing worse than an accepted standard that has been implemented in 15 different flavors throughout the supply chain." Indeed, one impetus behind the formation of WGRA was the experience with the WISPr roaming standard for WiFi: The Wi-Fi Alliance promoted the development of this roaming standard but ran into incompatibility problems. "WISPr has been implemented in at least four or five distinct flavors at this point, and I think that's stood in the way of adoption," said Engbers.

Members of WGRA include Sify, StoneBridge Wireless Broadband, Dockpoint, WiMaxPro.com, Wisper ISP, Airnet Telecom, Telelink Australia, News IQ, RemotePipes, Airpath Wireless, WeRoam, Starhome, Futura Technologies, Aramova, and Minuteman Support Services.
