  • Disturbance free operation close to other radio devices


The Westermo RT-320-HV is a Wireless LAN Node for on-board and stationary applications. It ensures reliable, high-speed data for applications such as video transmission, useful for instance in train to ground and inter-consist communication. The RT-320-HV, along with the application-specific ICL antenna, is designed to withstand the tough environment on-board trains, exposing the device to constant vibration, extreme temperatures, humidity and a demanding electromagnetic environment.

The radio module is calibrated to ensure fast hand-off, high RF sensitivity (even at high data rates/modulations), stable RF links, optimised DFS handling, etc. A GORE-TEX® membrane prevents internal condensation. High-level isolation between all interfaces enables direct connectivity to vehicle auxiliary power and protects against overvoltage and spikes/surge. IP66 protection prevents ingress of water and dust even at the quick connect QMA connectors.

An overall optimised design results in a compact form factor in combination with very high MTBF for easy integration and low lifecycle cost. Thorough type testing at independent labs certifies the compliance to a wide range of standards, not least EN 50155, FCC and EN 300 440 (the latter opening the possibility to use the 5.8 GHz band in the EU region). Meeting the requirements of the railcar market, the RT-320-HV is very well suited for deployment in any other application with severe operating conditions and tough environments, for instance in the mining or shipping industry
