Key facts

  • Standard compliant conformance testing for EU eCall and ERA-GLONASS
  • Extendable with support for next generation eCall over 4G and 5G with the R&S®CMX500
  • Automated test script inclusive DUT automation for common eCall standards with the R&S®CMWrun test sequencer (sample test plans included)
  • eCall PSAP certified by CETECOM

Ensure your eCall system is 100% reliable and rapidly sends alerts for a fast rescue chain that saves lives

Simplifies and accelerates the development and verification of your eCall or next generation eCall (NGeCall) systems


The R&S®CMW500 in combination with the R&S®CMW-KA094/KA095 PSAP eCall options and the R&S®CMX500 in combination with the R&S®CMW-KA098 are a powerful solution for functional testing, standard compliant conformance testing and performance testing for your eCall, NGeCall and ERA-GLONASS modules. The R&S®CMX-KA098 extension for next generation eCall allows you to test future IMS based eCall systems over 4G and 5G. The system does it all in a lab environment, saving time, reducing costs and minimizing field testing.

Features & benefits

The ideal solution for standard-compliant conformance testing

  • Test that your eCall module complies with the standards e.g. CEN, ETSI, GOST-R etc.
  • Verify that the IVS module can trigger an emergency call – automatically and manually
  • Verify eCall data transmissions and the voice connections to the public safety answering point (PSAP)
  • Compare received eCall data (MSD) with expected values
  • Verify GNSS receiver accuracy (GPS, GALILEO, GLONASS etc.) and visualize position results on OpenStreetMaps.
  • Use the R&S®CMW-KA09x remote interface to create your own test applications and scenarios.

Presenting the next mandatory eCall version, which is called NG-eCall with the latest radio access technology known as 5G NR. NG-eCall is driven by several factors, for example to reduce response time even further and to provide the radio access today and in the future. To demonstrate the NG-eCall functionality the CMX OBT and SMBV together with the KA09x Software is used for testing the whole functionality for an In-Vehicle-System.
