The wireless networks iPass supports utilize 802.11b, though PHS is available in some overseas markets. As an aggregator, iPass will support whatever new wireless technologies its partners deploy.
On a roaming basis, iPass supports the activities of the Wi-Fi Alliance. It also has defined a protocol, called General Interface Specification, that specifies how client software can interact with an authentication gateway, enabling the use of that client in any network supporting the protocol.
Strategically, iPass is collaborating with Intel on its Centrino platform. Clearly, iPass has a wide array of business relationships, and with its dial-up business as a base, its emphasis on a uniform global network experience and the large number of hotspots it supports, the company is in a good market position and rates as one of our top RFI contenders.

T-Mobile USA
The largest nationwide cellular operator, with service in 45 of the top 50 U.S. metropolitan-area markets, owns and operates the largest hotspot network in the world, which it acquired when it bought Mobilestar. T-Mobile's network, now called T-Mobile Hotspot, is unique in that it emphasizes carrier-grade equipment and is the only large network currently operated by a cellular operator in the United States.
