Rohde & Schwarz Provides Reliable Test Solution for eCall In-Vehicle System Modules
Rohde & Schwarz GmbH & Co
Press release date: February 19, 2014
To ensure fast emergency response times to automobile accidents and save lives, automatic emergency call systems will be mandatory for all new vehicles in the EU starting in 2015. Rohde Schwarz supports manufacturers today by offering a standard-compliant test solution for the wireless and GNSS-capable components of eCall in-vehicle systems.
Munich — Rohde & Schwarz will demonstrate its compact eCall test solution for in-vehicle emergency call systems for the first time ever at Mobile World Congress. The setup consists of the R&S CMW500 wideband radio communication tester and the R&S SMBV100A vector signal generator with integrated global navigation satellite system (GNSS) simulator. This setup allows manufacturers and suppliers of automatic in-vehicle system (IVS) to perform reliable and reproducible end-to-end conformance tests on their eCall modules.
When an accident occurs, the IVS connects with a public safety answering point (PSAP) via the local wireless communications network and transmits a minimum set of data (MSD) that includes the GPS coordinates of the vehicle involved. The Rohde & Schwarz test solution enables users to verify whether their IVS modem can successfully initiate an emergency call, transmit the correct MSD and establish a voice connection with a PSAP.
Rohde & Schwarz developed the R&S CMW-KA094 eCall application software specifically for this application. The software simulates a PSAP and controls the R&S CMW500 emulating a wireless communications network in the lab. It also controls the GNSS simulator supplying the coordinates required for localization. The test solution is fully automated thanks to the R&S CMWrun sequencer software and can be used right away. The user can test the RF interfaces and GNSS receiver and also check that the entire system is functioning properly.
With the advent of eCall, GSM and UMTS wireless communications technologies are now making their way into private vehicles. Rohde & Schwarz has spread its RF testing expertise to the automotive sector with its eCall test solution. The R&S CMW500 is a future-ready multistandard platform capable of testing RF interfaces such as WLAN, 2G, 3G and LTE for tomorrow's traffic telematics modules. The R&S SMBV100A can also be used to test navigation systems and other applications that require position information. The GNSS simulator offers a range of flexible realtime scenarios with up to 24 dynamic satellites for GPS, Glonass, Galileo and BeiDou.
Rohde & Schwarz will display the setup at Mobile World Congress in Barcelona (hall 6, booth C40). The R&S CMW-KA094 eCall application software, R&S CMW500 and R&S SMBV100A are now available from Rohde & Schwarz.
