Adaptive Broadband and AT&T Labs Collaborate on High-Speed Wireless Broadband Access System

Strategic Insights

— 1 min read

Researchers at the University of California, Berkeley, in collaboration with Adaptive Broadband Corporation and AT&T Labs, are working on deploying a high-speed wireless multimedia broadband access system on the Berkeley campus. This ambitious project aims to provide students with a seamless and high-speed internet experience, leveraging the AB-Access system's capabilities. The AB-Access system will enable real-time video conferencing, full-motion video, and high-speed internet access across the campus.

Key Takeaways:

  • The AB-Access system will provide wireless high-speed multimedia connections at 25 megabits per second, up to 400 times faster than dial-up service.
  • The system will facilitate real-time video conferencing, full-motion video, and high-speed internet access across the campus.
  • The project will enable researchers to analyze Internet usage behaviors and architect the next-generation network to handle multimedia and electronic commerce applications.
  • Adaptive Broadband is donating its AB-Access system, which it acquired last year, to support the research effort.
  • AB-Access has development roots at AT&T Laboratories-Cambridge, England, and leverages a patent-pending design of the Media Access Control (MAC) layer.
  • The system includes an instant provisioning capability and customers with portability for Internet and other data transmission needs.
  • The AB-Access technology was engineered to work at any frequency from 2 to 42 GHz, with initial releases targeted at 5 GHz (U-NII) and 2.5 GHz MMDS frequency bands.

Statistics:

  • 25 megabits per second: the speed at which the AB-Access system will provide wireless high-speed multimedia connections.
  • 400 times faster: the speed of the AB-Access system compared to dial-up service over a 56K modem.
  • 2-42 GHz: the frequency range at which the patented AB-Access technology works.
  • 5 GHz (U-NII) and 2.5 GHz MMDS: the initial frequency bands targeted by the AB-Access technology.
