Caltrain, in conjunction with Intel Solution Services and Nomad Digital Ltd., is the first rail line in the country to successfully complete a ÂÂproof of concept for wireless broadband access technology that provides continuous high-speed Internet access along a rail line at travel speeds of up to 79 miles per hour. For some time, Caltrain has been seeking technology solutions for providing high-speed wireless access that would give Caltrain passengers uninterrupted Internet links onboard moving trains.
The proof of concept, which was conducted along 16 miles of track between the Millbrae and Palo Alto stations, was deemed a success when multiple people surfed the Internet simultaneously, watched streaming video, answered e-mail and completed a large file download all while maintaining continuous connectivity at broadband speed.
Intel Solution Services, which is Intel Corporation's worldwide consulting organization, focuses on driving business transformation and competitive advantage through the practical application of new technologies. In addition to Intel Solution Services, major technology providers for the proof of concept were United Kingdom-based train communications specialists Nomad Digital, Sensoria Corp. of San Diego and Redline Communications of Toronto.
Nomad provided a mobile communication system which links the train to trackside wireless base stations, with radios located every few miles along the rail line. The company recently helped launch the worldÂÂs first broadband wireless service on trains in the UK on the London to Brighton line. Sensoria provided the wireless mesh routers which enables connectivity throughout the train and serves as the WiFi access point within each car. Redline Communications provided the radios that makes the connection between the train and the trackside. The company is a supplier of WiMAX equipment.
With the proof of concept successfully completed, Caltrain will continue work on engineering that is required before the wireless access can be implemented along the entire rail mainline.
The wireless backhaul is based on a WiMAX standard that uses unlicensed spectrum.
