It was a significant lesson in neighborliness for T-Mobile, which plans to install Wi-Fi networks in 2,000 Starbucks by year's end, making it the largest Wi-Fi network in the United States. T-Mobile is charging $30 a month for unlimited access, with walk-in Starbucks customers paying $2.99 for the first 15 minutes and 25 cents a minute thereafter. Starbucks plans to add Wi-Fi to 70 percent of its 6,000 locations worldwide in the next few years. Although T-Mobile is the first U.S. carrier to add Wi-Fi service to its offerings, most carriers are expected to follow with Wi-Fi services of their own. Sprint PCS has already invested in a Wi-Fi network called Boingo Wireless.

Rick Ehrlinspiel, chief executive of rival network Surf And Sip, set up a wireless network next door to the San Francisco Starbucks where T-Mobile unveiled its service Wednesday. And Ehrlinspiel was at the press event there, distributing information about his 150-spot network and getting a peek at the competition. His Surf And Sip's wireless network was accessible from within Starbucks during the event, albeit with a weaker signal than from Starbucks' closer and more powerful network. His network is also a bit slower, since Starbucks is offering zippy T-1 connections. Surf And Sip typically uses more affordable connections such as cable or DSL, and has both monthly and pay-as-you-go memberships available.
