Wireless mesh delivers unique ability to provide high-performance real-time video streaming in challenging subway environment to and from trains moving at 50 mph
After 198 people perished in the Daegu, Korea subway fire of 2003, the Seoul Metropolitan Rapid Transit Corporation (SMRT) began investigating real-time wireless video surveillance systems to help protect their subway riders and transit workers against potential fires, accidents, thefts and other harmful incidents. Now, after years of research and evaluations of several vendors' wireless equipment in a high speed and harsh subway environment, the SMRT has selected Korea Telecom with Global Telecom as the subcontractor to deploy Firetide Inc.'s wireless infrastructure mesh solution in Seoul's subway system. When completed in June 2010, it will be the first real-time, high-bandwidth mobile wireless video surveillance subway system in Korea and the world, costing an estimated total of $60 million.
"Firetide was selected because no other vendor's wireless mesh equipment could provide the high speed performance required to deliver streaming video from the station to moving rail cars and operate in one of harshest of environments for RF networks," said Mr. Jung Yeong-Hyun, project manager of Global Telecom. "We were also tremendously impressed with Firetide's sophisticated regional support organization that understood the difficulties posed by the subway system."
