R&S®CMWrun - Conformance testing solution for eCall/ERA-Glonass

Sequencer Software Tool

T&M solution

The European Union and the Russian Federation aim to have intelligent telematics-based vehicle safety systems in place by 2015 to speed up emergency response times in order to save human lives. eCall (emergency call) and ERA-Glonass (automated emergency response) are electronic safety systems for cars. The systems automatically call the emergency number for local emergency medical services in the event of a serious road accident.

Rohde & Schwarz offers a compact solution for automated, reliable and reproducible end-to-end conformance tests on eCall/ERA-Glonass modules independent of the real-world mobile network. The R&S®CMW-KA094 eCall and R&S®CMW-KA095 ERA-Glonass application software simulate a PSAP and remotely control the R&S®CMW500 wideband radio communication tester to emulate a cellular network in the lab.

To simplify extensive conformance tests, the R&S®CMWrun CMW‑KT110 sequencer software tool is added. It provides ready-to-use test sequences for eCall and ERA-Glonass modules in line with CEN/TS 16454 and GOST 55530 respectively. Required test sequences are conveniently selected and combined on the straightforward user interface. R&S®CMWrun automatically configures the R&S®CMW-KA094/-KA095 PSAP application software via remote control to execute the selected tests. It creates a complete test report with pass/fail indication for each IVS module. The ability to verify compliance with standards at an early design stage makes it possible to take corrective action and optimize an IVS module in a timely manner.

The R&S®CMW-KA094/-KA095 PSAPs with the R&S®CMW500 and R&S®SMBV100A test instruments and the R&S®CMWrun CMW-KT110 application are a compact solution for testing the functionality and standard-compliant conformance of your IVS modules in the lab. The test instruments are a future-ready investment and can be upgraded to meet upcoming test requirements.

R&S®CMWrun concept, features, interfaces and applications

Today the R&S®CMW500 is the leading, most popular multistandard platform for UE testing. It is used by network operators, test houses, handset vendors and chipset manufacturers alike. The R&S®CMWrun automation software meets all requirements for executing remote control test sequences on the R&S®CMW500 in R & D, quality assurance, production and service for both current and future wireless equipment.

The software engine is based on the execution of test DLLs (plug-in assemblies). This architecture allows easy and straightforward configuration of test sequences without requiring specific programming knowledge of how to remotely control the instrument. It also provides full flexibility when configuring parameters and limits for the test items provided in the standard-specific R&S®CMWrun package options.

The intuitive graphical user interface makes it simple for users to test wireless devices for compliance with the 3GPP protocols for various technologies.

The applications are diverse. For example, in combined user experience tests, synchronized markers show the IP throughput and current drain at a glance. During analysis, event markers help the user optimize IP throughput and battery life.

At the end of the test, an easy-to-read test report containing limits, test results and verdict is generated. The report is available in csv, txt, xml and pdf format.
