Claiming to meet the need for secure and reliable data connection to support railway digitisation, Westermo has launched a range of compact data networking products for onboard and trackside applications. The RT-310, RT-320 and RT-370 wireless local area network (WLAN) devices ensure reliable, continuous, high-speed data communications in extreme operational environments, supporting applications such as monitoring train speeds and track conditions, and providing onboard video surveillance and passenger hotspots.
The RT-310 and RT-370 are WLAN access points which support multiple-input multiple-output (MIMO) high-speed data transfer. The RT-320 is a multiple-mode WLAN connection point, which can be configured as an access point, or as client and bridge modes. The devices have been designed to provide robust solutions in applications where it is not possible to use network cables. These include transmitting information from a moving train to wayside monitoring stations and establishing a data connection between train carriages where a specialised coupler is not available for network cables 5Ghz radar bands are supported and robust Dynamic Frequency Selection features support improved radar detection.
The devices are approved to the EN 50121-4 standard for trackside applications, with the RT-310 and RT-320 also approved to the EN 50155 standard for onboard applications. The products are designed to withstand the challenging environments and demands of rail applications, including constant vibration, extreme temperatures and humidity. They are rated to IP66 for prevention of water and dust ingress, incorporate a GORE-TEX membrane to prevent internal condensation and have an operating range of -40°C to +70°C. High-level isolation between all interfaces protects against overvoltage and flashover. These features ensure reliability and an extended mean time between failures. A compact design enables easy installation into onboard applications and configuration is easy using a web management tool.
In addition to rail applications, all three devices are very well suited for deployment in other industries with severe operating conditions and tough environments, such as mining.
