Starting in 2021, Toyota and Lexus vehicles in the USA will be able to communicate with each other using short-range wireless technology and potentially avoid accidents as a result.
Dedicated Short-Range Communications (DSRC) systems are able to broadcast data up to 300 meters, sharing its location, direction and speed, with nearby vehicles. Other DSRC-enabled vehicles will be able to use this information to avoid collisions, identify potential hazards, and map traffic patterns.
DSRC communicates using the 5.9 GHz wireless spectrum band dedicated to vehicle-to-vehicle data sharing, and does not require a cellular or data network. It is also based on industry standards, so any vehicle with DSRC will be able to communicate with each other regardless of manufacturer.
(Toyota and Lexus became the world’s first automaker to sell and commercialize vehicles equipped with DSRC when the technology launched in Japan in 2015. As of March 2018, more than 100,000 DSRC-equipped Toyota and Lexus vehicles were on the road in Japan. )
