IEEE-802 Technologies for Fast Roaming

White Paper Belden

Effective train-to-ground communication

In this White Paper:

  • Influencing factors that determine Wi-Fi network quality
  • Technical options for improving the quality of new & existing wireless networks
  • Optimization approaches—established & additional options based on the latest devices to address specific requirements for reliability & security of mobile industrial applications


"The objective of train-to-ground communication is to establish fast and reliable signal transmission between trains and the subway and track-side infrastructure. Train networks can connect to WLAN clients on the train via specialized Wi-Fi with access points along the route."

"The network requirements for the AGV application are very similar in terms of coverage and interruptions. In this case, vehicles are moving autonomously through a manufacturing site to independently fulfill various tasks. The vehicles communicate with the infrastructure about sensitive and time-critical information necessary for autonomous operation, such as receiving control commands."
