eCall test from Rohde & Schwarz is certified ahead of April 2018 deadline
From April 1, 2018 onward, car manufacturers will be required to equip new vehicles for sale in the EU with an eCall module. This emergency call system automatically sends data to the emergency phone number (112) in the event of a serious accident, to reach emergency services.
Independent test house, CETECOM, has certified the eCall test solution from Rohde & Schwarz, which can be used to simulate a public safety answering point, in accordance with the EN standard. Manufacturers and suppliers can use the eCall test solution for acceptance tests of their installed emergency call systems. The Russian equivalent emergency call, ERA-Glonass, can also be tested with an extension.
The eCall test solution is the first of its kind to be certified by an independent test body, says Rohde & Schwarz. CETECOM has examined the implementation of the eCall test public safety answering point (PSAP) in the Rohde & Schwarz solution for the pan-European emergency call system and certified it as compliant with the CEN EN 16454:2015 standard. This is a pre-requisite for tests compliant with Commission Delegated Regulation (EU) 2017/79.
CETECOM has been officially designated as a technical service for eCall by the German Federal Motor Transport Authority.
The R&S CMW-KA094 test solution is the first independently certified test PSAP system based on a wireless communications test platform.
Rohde & Schwarz thus offers a compact solution for reproducible end-to-end functional tests and standard-compliant conformance tests of eCall and ERA-Glonass modules. These tests can check whether the installed modem properly initiates an emergency call in the event of a motor vehicle accident, correctly acquires the relevant data and sends it via the mobile network, and is able to establish a voice connection to the PSAP. Test houses and vehicle manufacturers use this for type approvals and for other tests requiring the emulation of mobile networks, such as location-independent testing of a car telephone.
The R&S CMW-KA094 application software specifically developed for eCall is based on the R&S CMW500 platform in combination with the R&S SMBV100A GNSS simulator. The software simulates a PSAP and controls the R&S CMW500, which emulates a mobile network in the lab. It also controls the GNSS simulator, which provides the position data of the accident location. The R&S SMBV100A additionally supports the GNSS receiver performance tests in accordance with Commission Delegated Regulation (EU) 2017/79 Annex VI. The eCall test solution can be fully automated with the R&S CMWrun sequencer software for further conformance tests, enabling users to directly utilize ready-made test sequences for eCall and ERA-Glonass modules compliant with ETSI TS 103 412, CEN EN 16454 or GOST 33467. Currently, rohde & Schwarz is also developing test features for the next generation eCall over LTE system and making the corresponding solution fit for the future and for testing new vehicle telematics units.
