The North County Transit District of San Diego installed indoor and outdoor wireless networks from Strix Systems, the company announced. The wireless networks provide real-time mobile communications for the district’s Coaster rail line, the second most traveled rail line in the U.S. Railways and transportation are a strategic market for wireless mesh networks, said Nan Chen, vice president of product management and marketing for Calabasas-based Strix. The Strix wireless systems will be used for remote video surveillance inside the trains and the surrounding track to improve safety; and for encrypted railway communications to secure stations, tracks, bridges and tunnels. The system is solar powered to provide connections 24/7 uptime and emergency backup. The U.S. Department of Homeland Security funded the wireless system.
