NXP Semiconductors designed car-to-x (C2X) communication system and gave a live demonstration of car-to-x (C2X) communication on a public road in the Netherlands. This is an automotive-ready hardware platform for connected mobility. NXP has co-developed the C2X platform with Australian-based Cohda Wireless. Combined with telematics for location-based services and networking security, the platform enables the fully connected car and is therefore a major milestone towards mass deployment for safer road traffic.

Car to Car Wireless Communication

Car to Car Wireless Communication

Imagine the possibilities if instead of the car simply being a passive receiver of information, it was actually an active information source. With IEEE 802.11p technology, the dedicated wi-fi standard supporting Intelligent Transportation Systems (ITS) applications, that is exactly what is possible. With key information being passed seamlessly between vehicles over 802.11p safety on roads can be dramatically improved through features such as forward hazard warning.

C2X communication uses IEEE802.11p, a wireless standard designed specifically for automotive applications. This allows cars to communicate with each other (car-to-car communication) as well as with intelligent traffic infrastructure (car-to-infrastructure communication) around them. The newly developed C2X platform from NXP and Cohda actually “sees” around corners in order to recognize traffic blocks or risks before they are visible to the human eye. Drivers therefore receive early warnings of cars hidden from sight behind trucks or approaching from around corners. Other use cases are warnings about emergency vehicles and traffic jams, or traffic light signals allowing drivers to adjust their speed and optimize driving.

The C2X platform is able to meet the requirements of the automotive industry: reliable signal reception for fast-moving objects even in difficult surroundings, cost-efficient design, and flexible programming. It uses Cohda’s Advanced IEEE 802.11p radio and is based on NXP’s multi-standard radio reception platform. NXP’s expertise as global leader in car entertainment semiconductors and Cohda’s patented reception algorithms are critical factors for successful development.
