"You're going to see a lot more people with video cameras in their home," says Jennifer Sterns, a marketing manager at TDS Metrocom, a communication services provider located in Madison, Wisconsin. "They can watch from work SO they can see their babbysitters." 3.6 WIRELESS ON WHEELS Engineers at the University of California-San Diego (UCSD) have created the world's first bus that allows its passengers to access the Internet and down- load files at a peak speed of 2.4 Megabits per second-even while the vehicle is moving. The broadband wireless bus dubbed the "CyberShuttle" combines a fully mobile 802.11b wireless local area network inside the bus, with Web access through QUALCOMM's CDMA2000 1xEV wireless wide-area data network installed on the UCSD campus and at the company's San Diego headquarters. "Our students and faculty are getting a taste today of wireless technology that most of the world will not be using until years from now," says Elazar Harel, the university's assistant vice chancellor for administrative computing and telecommunications. "This bus is one of the first places where we will be able to experiment with technical as well as social aspects of third-generation [3G] wireless services in a real-world environment." The commuter bus shuttles students, faculty, and visitors between the main UCSD campus in La Jolla and the Sorrento Valley train station. The trip typically takes 15 to 20 minutes, enough time for commuters to check e-mail or surf the Web. Passengers can also watch streaming video or listen to high-fidelity music because they are connected to the Internet in a dedicated 1.25-MHz channel at speeds up to 2.4 Megabits per second. "The campus already has 1,200 users registered to use 802.11, and all of them can just as easily log on while riding the bus," says Greg Hidley, head of technology infra- structure. "To use their laptops or personal digital assistants online, all they need is the same wireless card they use elsewhere on campus, and they are automatically
