Qosmotec Develops Virtual Drive Tests for Car-to-Car Communication

Together with RWTH Aachen Universtity and Vector Informatik Qosmotec develops a signal strength emulator for hardware-in-the-loop (HIL) test facilities in the automotive industry. This poses a challenge, because public mobile networks and Car-2-Car technology have different parameters. “In Car-2-Car communication we are dealing with Ad-hoc networks”, explains Qosmotec’s Managing Director Mark Hakim. “This means there is no distinction between fixed base stations and mobile subscribers. All devices communicate directly with each other while they are moving. They also assume different roles, e.g., message broadcaster, router or mobile receiver.” For this ad-hoc network emulation, a new hardware setup had to be developed with configurable radio links between all network participants. Currently Qosmotec works on traffic and channel models that simulate driver behavior and resulting radio propagation impacts on the communication channel. Click here for details.
