Cyber shuttle service initiated in SD UC San Diego Unveils World's First Bus With Mobile, High-Speed Internet SAN DIEGO, Apr 02, 2002 (ASCRIBE NEWS via COMTEX) -- Engineers at University of California, San Diego have unveiled the world's first bus that enables its passengers to access the Internet and download files at a peak speed of 2.4 Megabits per second--even while the bus 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 nearby. "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," said Elazar Harel, the university's Assistant Vice Chancellor for Administrative Computing and Telecommunications (ACT). "This bus is one of the first places where we willl be able to experiment with technical as well as social aspects of third-generation (3G) wireless services in a real-world environment." UCSD is already operating a large production 802.11b wireless network on campus, and its faculty and staff have been testing QUALCOMM's 1xEV technology for about two years. "We are very excited about this initiative and are thankful to QUALCOMM and to all UCSD participants for their contribution to the project," Harel added. The CyberShuttle is part of an ongoing initiative undertaken by ACT, UCSD's Irwin and Joan Jacobs School of Engineering, and the California Institute for Telecommunications and Information Technology [Cal-(IT)2]. "Thanks to QUALCOMM, we have access to the most advanced wireless network in the world," noted Ramesh Rao, a leading wireless expert and director of the UCSD division of Cal-(IT)2. "Now we are tapping into that network, and encouraging our researchers and industry partners to develop new services and technologies that lead to anytime/anywhere high-speed access to the World Wide Web." The commuter bus shuttles students, faculty and visitors between the main UCSD campus in La Jolla, CA, and the Sorrento Valley train station. The trip typically takes 15-20 minutes, enough time for commuters to check email 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--many times faster than conventional "wired" access using 56K modems. "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," said Greg Hidley, head of technology infrastructure for Cal-(IT)2 and director of Engineering Computing for the Jacobs School. "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 handed off from the local network, through the 1xEV network, to the Internet." 1xEV is formally known as 'CDMA2000, High Rate Packet Data Air Interface Specification' and is QUALCOMM's first 3G offering. The company's facilities are equiped with 1xEV antennas, providing coverage up to a 10-mile radius. In 2001, the company installed similar equipment on top of the nearby Jacobs School for use in engineering, wireless, and related research projects. A team led by ACT's Lou Forbis and Don McLaughlin configured and deployed the broadband system for the bus, linking an off-the-shelf 802.11 access point with a 1xEV modem, both running on electric power from the bus's battery. Now that the mobile broadband system is up and running on the bus, researchers are looking for other ways to experiment with the technology. "We are getting ready to test a backpack version," said Hidley. "It's an access point-in-a-box that would allow you to take it anywhere on campus and create a zone within a radius of 300 feet where users could get onto the Internet using 802.11b and CDMA2000 1xEV technology."

Express Network Megabyte Wireless Data Pricing for Business: << Perhaps the GSM bunch will launch EDGE as another "premium" service like HSCSD >> Business customers can qualify to add the new Megabyte pricing to numerous digital calling plans: - $35 per month for 10 MB + $0.008/Kilobyte overage - $55 per month for 20 MB + $0.006/Kilobyte overage - $75 per month for 40 MB + $0.005/Kilobyte overage - $100 per month for 75 MB + $0.004/Kilobyte overage - $150 per month for 150 MB + $.0025/Kilobyte overage Casual users cam pay an extra $30 a month to use minutes from their voice plans for data as an alternative to the above. What do you consider "Non-Premium" Service? - Eric -

Carranza, it takes some basic understanding of how radiowaves propagate, both in empty space and empty deserts, and especially in both rural and urban space. When will the doctor "say" that base station density is proportional to user density and ARPU, comes kind of naturally, the difference between 10% and more than 100% penetration, or is he still dreaming of something like five computers serving all of mankind?? (sorry, was it 69 or 96 satellites??) Cingular had some good pseudo-technical-practical slides, but I am "forced to admit" it takes some basic understanding to understand why they decided to make the slides they made them. A real practical thing is that GSM operators have been able to collect data from the position of the handsets since the start of GSM, thanks to the inbuilt need for adjusting the position,timing of the time slots.(handset need to adjust them back and forth depending on distance to base station, pre-correcting for the time it takes for the time slots to reach the base station). Same for measuring where within cells EDGE can be used, what channels to assign,etc, all those "dynamic channel allocation" and "hierarchical" things. One dynamic example I tried to use long time ago was the rock concert in the middle of usually empty rural area, suddenly tens of thousands of teenagers, plus those to handle, take care of them, during a couple of days. Btw, finnish rock concerts usually also deploy 802.11b, but one cannot really trust it to work as there is no way of predicting nor measuring what is going on, nor control the system when it goes haywire. (something to do with CDMA, power control and lots of quacking ducks crashing the cocktail party??) Ilmarinen
