Harman adds V2X capability to Connected Car platform

Technology News |
Infotainment system vendor Harman shows a V2X-enabled version of its LIVS Connected Car platform at the Geneva Motor Show. Based on NXP’s Roadlink technology, the platform automatically exchanges information with other vehicles and the infrastructure, contributing to improve traffic safety.

For the communication, the platform uses the IEEE 802.11p standard, a modified version of the widespread WiFi wireless data communications technology that has been optimised for automotive real-time requirements. With V2X, the LIVS platform gets aware of critical traffic situations such as traffic stalls or slippery roads at distances far beyond conventional vehicle sensors such as radar, lidar or the like. According to NXP, the platform has a range of about 1.5 to 2 kilometres (roughly 1 to 1.5 miles).


IEEE 802.11p is not the only technology that lends itself to V2X application; in particular large mobile radio network providers are eager to implement these applications with 4G or, even more so, 5G technology. However, for the time being NXP believes that 802.11p is the only available technology suited for the extremely demanding real-time requirements in V2X applications. “We do not believe that V2X ever can be based solely on mobile radio – cellular networks simply have latencies that are much too high for this purpose”, a spokesperson explained. “It will take years before 5G will be comprehensively available – and even then it takes a lot of testing and tweaking to each the same performance level as 802.11p.”
