21st Century Internet--Engineering an 'Always-On' World
The 21st Century Internet is rapidly extending beyond the wired world of PCs into a pervasive information infrastructure, enabled via a combination of wireless local area networks, the third generation of cellular phones, satellites, and the increasing use of the FCC unlicensed wireless band. This universal access to the Net will change our personal lives as well as making possible a new generation of SensorNets to give us real-time feedback about our environment. College campuses are perhaps the best "early warning systems" for how human behavior will evolve as this "always-on" internet world develops. I will describe how Cal-(IT)2, one of four new California Institutes for Science and Innovation, is organizing its "future of the internet" research. We are working in an interdisciplinary fashion, with real world challenges in earthquakes, pollution monitoring, biomedicine and transportation congestion driving experiments in our "Laboratories for Living in the Future," built on campus and projected outward into the community. We are currently exploring opportunities for collaboration between Cal-(IT)2 and UC Santa Cruz, a participating campus in two other of the Institutes.

Broadband Wireless Internet is Here Today
• Wireless Internet “Watering Holes”– Ad Hoc IEEE 802.11 Domains
– Real Broadband--11 mbps Going to 54 mbps– Security and Authentication can be Added
• Cellular Internet is Rolling Out– CDMA2000
– South Korea Fast Growth– San Diego, DC Trials This Summer
– WCDMA– Japan NTT DoCoMo Launched Oct 2001
