Kingwaytek Technology, a provider of digital maps for car navigation, is testing autonomous driving using C-V2X wireless communication infrastructure at an open experimental field in northern Taiwan, according to company president San Huang.

This is the first case of using C-V2X to test autonomous vehicles in Taiwan.

C-V2X, currently based on 4G MEC (multi-access edge computing) architecture, is used to provide the real-time time length of traffic lights for autonomous vehicles to have enough lead time for making driving decisions, Huang said. Image recognition of traffic lights runs the risk of misrecognition due to reflections or weather conditions, and it cannot tell how long a traffic light will last, Huang noted.

Sensing devices, including LiDARs, radars and automotive cameras, have physical limitations, but 5G's low latency and high data transfer speed will allow C-V2X, copuled with edge computing, to shorten the minimum distance allowable for making response or hike the maximum running speed, Huang noted.
