V2X end-to-end tester demonstration spotlights driving hazards

September 30, 2015 // By Paul Buckley
Rohde & Schwarz, Vector and Commsignia plan to jointly present a V2X end-to-end tester which demonstrates how, for the first time ever, an onboard unit in a simulated vehicle environment receives 802.11p-based messages under real-world conditions and displays them.

The joint 802.11p test demonstrator from Rohde & Schwarz, Vector and Commsignia will be on display at the ITS World Congress in Bordeaux October 5 to 9, 2015 at the Rohde & Schwarz booth (F22).

The V2X end-to-end tester for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) applications is based on the fully automated R&S TS-ITS100 RF conformance test system from Rohde & Schwarz.

Future intelligent transport systems (ITS) will be implemented using standards such as IEEE 802.11p WLAN to enable vehicles and infrastructures to share information in order to warn drivers of hazards such as accidents, construction zones and slippery roads.

The RF conformance test system is augmented by the Vector CANoe application and communications test system, which monitors radiocommunications and internal vehicle buses and even simulates some of them. The Commsignia ITS-OB2-M onboard unit for 802.11p serves as the DUT. The overall system is the first to enable automotive manufacturers and their suppliers to verify the functionality and performance of vehicle-to-vehicle applications with an end-to-end test – from transmitting RF signals over a simulated channel to receiving the RF signal via an onboard unit and subsequent presentation on an in vehicle display.
