Nomad Digital Ltd., in conjunction with Caltrain and Intel Solution Services, has successfully completed a "proof of concept" for a WiMAX-based technology that provides continuous high-speed Internet access for Caltrain passengers. This is the first instance of a trial for a mobile 802.16 WiMAX network, making Caltrain the first train system in the United States equipped with a wireless network.

The "proof of concept," which was conducted along 16 miles of track between the Millbrae and Palo Alto stations at travel speeds of up to 79 mph, was deemed a success when multiple passengers simultaneously surfed the Internet, watched streaming video, answered e-mail and completed a large file download while maintaining continuous connectivity at broadband speed.

"For some time, Caltrain has been looking for a way to provide uninterrupted high-speed wireless access for its passengers," said Randy Rudolph, director of information technology and telecommunications, Caltrain. "With Nomad's cutting-edge WiMAX-based technology and the successful trial completion, we can now move forward with plans to implement a wireless network along the entire rail mainline."

Nomad's innovative mobile communication system links the train to trackside wireless base stations, with radios located every few miles along the rail for a reliable and seamless broadband connection to the Internet. This unique network, based on WiMAX technology (IEEE 802.16/WiMAX), allows for a continuous broadband connectivity to trains traveling through tunnels and/or underground. Passengers can use their laptop to access the Internet throughout a train journey without the need for additional plugs, wires, adapters, software, hardware or mobile phones. Caltrain operators also benefit from this technology because they are able monitor the performance of their trains, install real-time security CCTV and locate all their fleet at any one time.
