Our Customers

Rail operator customers. System integration customers.


These are just some of our customers. Rail operators, telecommunications companies, telecommunications vendors and other vendors around the world benefit from our GSM-R and signalling testing solutions.

Many of our customers have different requirements but they generally share a common goal – the need to collect data, to test and monitor communications on their GSM-R and ETCS signalling networks. They choose us because they rely on us to use our GSM-R testing and ETRMS experience and expertise to help them find practical and effective solutions. This includes solutions for GSM-R interference testing.

That’s because the Comtest Wireless NetProbe solutions enable them to run bespoke reports, cross reference queries, analyse situations, identify issues, predict trends and build their expertise, all of which enables them to make wiser decisions.

The NetProbe products support active and passive data collection and analysis from multiple types of equipment both on-board trains and wayside, along the track. Contact us to find out more about these attended and unattended solutions.
