Channel Load Generator

802.11p - Qosmotec Software Solutions GmbH

When many cars are equipped with 802.11p communication technology, high traffic density will also cause significant load on the radio channel. From normal wireless communication systems it is a known problem, that many users can cause a complete breakdown of the network. Car-to-X communication technology tries to protect itself against those kind of breakdown by a carrier sensing mechanism: Each communication device has to check first, if  the radio channel is busy. In that case, it waits for a random delay to avoid packet collision on the radio channel, which causes a loss of both collided packets.
