After four years of testing, the French TGV railway company launches its high-speed trains, broadband access based on Wi-Fi technology. During the movement of airborne wireless network will be connected to the satellite, and during stops - the Wi-Fi- network of the railway station. End users get the bandwidth at 2 Mbit / s, according to Silicon.
Specialists of the company had to overcome many difficulties associated with speed of movement: in some areas trains are accelerated to 320 km / h. The main drawback of the system is to limit the number of concurrent users, which so far can not exceed 50. The standard is usually a train traveling 375 passengers.
