Solution to address GSM-R interference

Comtest Wireless offers solution to address GSM-R interference challenges (without a hiring a battalion of radio engineers).

Using proven Comtest Wireless technology, NetProbe Interference Modules provide rail and signalling operators with a complete solution to detect and analyse interference issues. As a result, the detailed interference reports can be used as a basis for engagement with mobile network operator (MNOs), third parties or legal entities, to address the issues.

A typical solution gives customers a toolkit that enables them to identify interference ‘hotspots’ using GSM-R performance data collection and analysis equipment installed on board operational trains.

The systems can perform tests with every GSM-R modem currently available in the market, making it easy to continuously signal levels (ie forcing UMTS 900) and therefore identify active operators and technologies. Read more.
