Successful debut for Car-to-X test systems
It had something of a premiere: For the first time Qosmotec officially showcased its test bench setup for Car-to-X communication testing. At the 8th Car2Car Forum at Stadthalle Braunschweig we had built up our 5-port QPER system with two IEEE 802.11p capable radio modules communicating with each other via a radio link, on which signal strength was controlled by our emulation software. Additionally, the two modules were controlled via the CANoe software from Vector Informatik. “Last year at the Car2Car Forum in Munich, we planned to establish this co-operation with Vector. At this time, we did not even have the slightest idea, whether those to systems really fit together. All the more proud we are that we could demonstrate a fully integrated environment, executing several typical traffic scenarios like emergency break situations, slow vehicle warnings or communication between cars and infrastructure like traffic lights, only eleven months later ”, says Qosmotec’s Managing Director Mark Hakim.
The demonstration attracted many of the 250 congress participants, who appreciated to see a complete example for a hardware-in-the-loop test benches on our booth. Together with car manufacturers and vendors of radio equipment, we identified an important application case, that shall be followed up in the near future. “We want to proof the negative impact of WLAN noise from IEEE 802.11ac and 802.11n on the Car-to-car communication”, says Mark Hakim.
Besides to this setup we showed a first concept, how to extend interoperability tests with other signal propagation effects like Doppler and Multipath fading. Also we specified on the congress, how to support the ETSI Plugtest, that will be hosted by TASS international in March next year in Helmond, with Qosmotec test equipment.
