Roaming is now a major focus for the wireless networking industry because of the growing number of cafes, hotels and airport lounges where people can pay a small fee for a day's worth of wireless Internet access. But so far it's a fragmented group of about 1,200 locations in the US, which is expected to grow to about 42,000 by 2006, according to statistics from research firm In-Stat/MDR. Complicating the matter is the creation of wireless Internet service providers like Boingo Wireless and Sputnik. These companies have crafted partnerships with most of the public hot spots in the United States. But because there is no roaming standard, a Boingo Wireless subscriber can't roam onto a Sputnik network. The problem is similar to the early days of mobile phones, when there were no roaming agreements, making for limited areas of mobile phone coverage for every carrier. But a decade's worth of work crafting roaming agreements and roaming standards now makes it possible for any mobile phone to call any other mobile phones. The standards for Wi-Fi -- also known as 802.11b -- that are being worked on would provide a single way to do the complex task of letting someone log on to a rival host's network then get billed appropriately. The difficulties aren't necessarily of a technical nature, although that is, of course, present. Mainly, it's deciding how to share the revenue. "When roaming agreements and standards come into play, consumers and corporations are going to want equitable pricing," said Chuck Jacobs, president of Andrew, which uses Wi-Fi networks to help make cellular telephone coverage better inside buildings. The industry has not come to a consensus on how much wireless Internet providers should charge each other for connecting to the network. One thing working against Pass-One, though, is it's a relative foundling, its members having just met last week for the first time to draft its charter. It costs $10,000 to become a member. "Pass-One is a relatively new body of standards -- just came back from their conference in Boston," said Jon Russo, vice president of marketing for iPass, which makes wireless software. It's a member of both WECA and Pass-One. "Pass-One is still in the process of figuring out the impact they want to have on the industry," he added.
