The Westermo Ibex-RT-220 is a Wireless LAN Node for on-board and stationary applications. It ensures reliable connection for applications such as video transmission and TCMS, especially useful for transparent inter-consist links (ICL) with automatic reconfiguration.

The Ibex-RT-220, along with the application-specific ICL antenna, is designed to withstand the tough environment on-board trains, exposing equipment to constant vibration, extreme temperatures, humidity and a demanding electromagnetic environment.

The radio module is calibrated to ensure 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 (powering over PoE is also available). 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 in space restricted & outdoor installations 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 300440 (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-220 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.
