Axell Wireless has extensive experience in railway applications. Our work encompasses both trackside apparatus and onboard train applications. Our solutions are well adapted to the specific railway requirements regarding reliability and redundancy and our products comply with the often demanding physical requirements.
We offer coverage solutions for GSM-R and public safety systems such as TETRA, based on established off-the shelf products. For other frequency areas we can offer almost any combination of customer specific repeater system, designed and built to fit the most detailed requirements. We also offer multioperator OnBoard solutions for any combination of frequency bands; GSM-R, GSM900, GSM 1800 and UMTS.
The forthcoming ambition to roll out ERTMS, the European Rail Traffic Management System with uniform and unique signaling standards throughout Europe puts new higher requirements on the GSM-R systems such as continuous and redundant coverage along all railway tracks including good tunnel radio coverage. This is the very core of the Axell Wireless competence area, and we can support it with a complete, dedicated GSM-R product portfolio.
Axell Wireless’s expertise and broad product portfolio within tunnel radio coverage for any frequency band - TETRA, GSM-R, GSM 900, GSM 1800 or UMTS - is a great advantage when a seamless result is of great importance. The use of repeaters in tunnel radio applications has been shown to be ideal because of space and RF propagation issues. A typical installation of radio coverage in a longer tunnel uses optical fibre fed repeaters and radiating cable. The repeaters at the mouth of the tunnel can either be fed via optical fibre from the nearest base station or via an antenna. Shorter tunnels can be covered with antenna fed repeaters. Antennas are also an alternative for longer tunnels, depending the existing preferences and requirements.
