Bay Area Goes Wireless To Secure Bridges, Tunnels

摘要

In a homeland security project, the California Department of Transportation is using multiple wireless systems to transmit surveillance data from seven bridges and three tunnels in the San Francisco Bay area to a command center in Oakland. The department, known as Caltrans, has completed the first phase of the $20 million Bay Area Surveillance Enhancement project. BASE includes installation of up to 15 point-to-point wireless links spanning distances of as much as 16 miles each and transmitting data at 90M bit/sec., according to IT industry executives involved in the project. The wireless technology is being tied to 250 video cameras that will use video-over-IP technology to transmit images to the command center.
