Transportation corridors create demanding wireless environments. Long, linear distances and infrequent wired Internet points-of- presence demand multi-hop networks. Travelers expect high-speed uninterrupted Internet service for their daily commute. Security for
highway and rail lines requires high-bandwidth video surveillance.

 
 
Traditional earlier generation wireless mesh networks perform poorly in this demanding multi-hop environment. But the MD4000 third-generation network offers very high performance for mobile and corridor applications. MeshDynamics' unique software-based routing algorithms offer special features for these environments.

MeshDynamics is undergoing successful trials in high speed rail networks designed to provide commuters with Internet service. MD4000 nodes along the tracks are used along with one or more nodes mounted on the trains to provide uninterrupted transparent service to commuters while in motion.

MeshDynamics' sophisticated internal routing algorithm allows very rapid association of the mobile nodes with the stationary nodes as the train moves. The MeshDynamics technology supports mobile nodes at speeds to 250 Kph (>150 mph), with additional features in development to allow speeds up to 400 Kph (>240 mph). All of this allows commuters uninterrupted Internet access at track speed or in the station.
