Rohde & Schwarz CMW communication and Bluetooth tester

Rohde & Schwarz T&M equipment adopted by Renesas for test of IEEE 802.11p devices

The IEEE 802.11p standard is one of the candidates for vehicle-to-everything (V2X) communications. Semiconductor manufacturer Renesas Electronics is using Rohde & Schwarz test solutions when developing, manufacturing and conformance testing its devices in line with IEEE 802.11p.

Developments of wireless automated communications technologies continue in the field of autonomous vehicles and connected cars in order to improve road safety.  At present, various wireless technologies are under discussion for implementing vehicle-to-everything (V2X) communications. IEEE 802.11p is one of the promising candidates.

Design of IEEE 802.11p devices
For analyzing IEEE 802.11p transmitter signals and receiver measurements in the development phase, Renesas is using the R&S FSW signal and spectrum analyzer and the R&S SMW200A vector signal generator with fading capability.  The integrated fading capability of the R&S SMW200A provides a testing environment in line with the IEEE 802.11p standard.

RF conformance testing
Renesas has adopted the R&S TS-ITS100 RF conformance test system that is specifically designed for standard-compliant testing of components for vehicle-to-vehicle applications and intelligent transport systems (ITS) in line with IEEE 802.11p. This automated test system can be used throughout the entire value chain – from R&D to precompliance and compliance testing. Using the R&S CONTEST sequencer software, which was developed for RF conformance tests, the R&S TS-ITS100 makes it possible to verify compliance with regional standards such as ETSI EN 302 571 in the EU, IEEE 802.11-2012 in the USA and the ARIB standard in Japan. The test system also covers specific performance tests as defined by the Car-2-Car Communication Consortium (C2C-CC).

Production testing
For production testing of IEEE 802.11p devices, Renesas has chosen the R&S CMW100 platform. The turnkey solution is based on the R&S CMWrun software and streamlined to meet Renesas requirements. The R&S CMW100 offers an integrated testing concept for automated production environments.
