NetProbe Unattended

 Comtest Wireless NetProbe Unattended monitoring

Automated GSM-R & signalling data collection with NetProbe Unattended

NetProbe Unattended makes it easy to schedule, collect and compile telecom and signalling data in real-time, using unattended test systems on-board trains and platforms. 

It is a simple and cost effective way to identify and source signalling and telecoms failures in real-time, on a limited budget.

In just the size of a shoebox, it enables rail infrastructure operators to receive real-time analytics and identify network issues quickly – and requires minimal engineer maintenance visits.

This is why NetProbe Unattended is easy to deploy on trains, platform or wayside, and enables full end-to-end call tracing in real-time. The signal level and quality measurement data is collected by the on-board unit, statistically compiled into configurable ‘packets’, and then transmitted to the responder server.

It provides an in-depth view of:

  • All railway communication systems (GSM-R, OMC, signalling and interlocking)
  • ERTMS/ETCS service coverage
  • Performance data for repeat test patterns, alarms, measurements and events
  • Issues and inefficiencies with handover failures, service drops etc
  • Radio measurements geo-positioned from GPS, time synchronised and then notified in real-time

The range of data collection equipment includes:

  • Rack mounted solutions, supporting 8 watt cab radios
  • Single boards for compact installations
  • Trolleys on test or operational trains
  • Portable backpacks on test or operational trains
