First independently certified eCall test solution unveiled by R&S

The eCall test solution from Rohde & Schwarz is the first of its kind to be certified by an independent test body. 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 prerequisite 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.

After March 31, 2018, manufacturers must equip new vehicles for sale in the EU with an eCall module. The R&S CMW-KA094 test solution is the first independently certified test PSAP system based on a wireless communications test platform.

Rohde & Schwarz offers a compact solution for reproducible end-to-end functional tests and standard-compliant conformance tests of eCall and ERA-Glonass modules. The prescribed conformance tests can be performed with the test solution. Manufacturers and suppliers use these tests to 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 solution for type approvals and for other tests requiring the emulation of mobile networks, such as location-independent testing of a car telephone.

This first certification of an eCall test solution by an independent body demonstrates that Rohde & Schwarz is an extremely reliable partner for the automobile industry – many global OEMs use the R&S CMW500 wideband radio communication tester and rely on the field-proven Rohde & Schwarz test solution. Currently the company 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. Along with eCall, Rohde & Schwarz supports the automobile industry with test solutions for e.g. V2X communications (from a vehicle to other users).

The technical Basis

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. This additionally facilitates demonstration of the functional capability of the overall system in accordance with Commission Delegated Regulation (EU) 2017/79.

Clarifying Machine Vision with High Quality Sensors
Automated imaging technology is everywhere we look. As cameras and their processing units get ever smaller, they are moving into ever more industries - from speed cameras and factory production lines to diagnostic medicine. For many of these applications, image quality is critical - but what does image quality really mean? Different applications will require quite distinct performance characteristics. Understanding camera specifications, differences between CCD and CMOS sensors, and features such as real-time processing or near-infrared (NIR) can help guide the camera selection process to produce better imaging results.
