Volkswagen will communicate vehicles

The first vehicles equipped with wireless communication technology (pWLAN) will appear in 2019. Within a few milliseconds, vehicles will keep up to date on traffic jams.

The most important advantage of this system is the transmission of data, important for traffic safety, both between car manufacturers (Car-to-Car) and between cars and road infrastructure equipment. Thanks to this solution, knowledge of the traffic, accidents or other important traffic events will be available to other drivers within 500 meters.

Volkswagen's technology is based on the IEEE 802.11p (pWLAN) standard developed by the automotive industry to allow direct communication between cars and road infrastructure equipment. This technology has been tested on international markets by various car manufacturers. Thanks to it, within a few milliseconds it is possible to exchange important information, warnings, and data collected by sensors locally. The area within which the vehicle collects important data has been expanded by several hundred meters and allows you to peek into where the "senses" of the car do not directly reach.

Data exchange takes place in a frequency band specifically designed to increase road safety and efficiency. Because it has local coverage, data is not centrally collected and is available regardless of cellular coverage. What matters - their customers do not bear the cost.
"Through network collaboration, we want to increase road safety, and this is best achieved through the rapid diffusion of common technologies," said Johannes Neft, head of Volkswagen's Brand Development Division. "It is important that this technology is used by the widest possible number of car manufacturers and partners," added Neft.

The basis of the system at the time of its introduction in 2019 will be warnings and information on current dangers in local traffic. With the new technology, potential threats can be identified, for example, when a car starts to brake violently or when the car's sensors detect a roadblock on the roadway. Within a few milliseconds, this information can be passed around the environment so that other participants have a chance to react accordingly to the risk. When police and rescue services are equipped with pWLAN technology, drivers will be informed in advance about the distance and direction of the privileged vehicle - long before it can be heard or seen.

Institutions responsible for road infrastructure in Germany, the Netherlands and Austria have announced the pWLAN technology for special trailers locking the motorway belts at road works to prevent the risk of slipping on them.
