6 ON-BOARD TRANSIT WIFI WITH PUBLIC BACKHAUL ONE PER TRAIN CAR IN CONSIST WIRED BACKHAUL TO BRAIN CAR ON-BOARD TRAIN/BUS ROUTER WITH MULTIPLE WIRELESS LINK AGGREGATION 100 MHz 50 MHz Cellular Carrier WiMax Carrier R 60 MHz Local Access 4-6 Mbps Satellite Carrier Local network can be highspeed and support infotainment and other applications. Still limited by weakest device assocciated per train car. WIRELESS LINKS BETWEEN CARS BACK TO BRAIN CAR Wireless backhaul is spotty and variable in speed and latency. During peak times network is congested which leads to diminished service to transit vehicle. Best case; maxiumum throughput achievable is unacceptable for either passenger or operational requirements.
