VLC makes visible light from LEDs used in automotive headlights, making it possible to create a low-cost automotive mesh network. Intel has been working on VLC research since 2008, and Roberts is looking to develop this technology as a communication platform between cars and cars. Roberts is an advocate of the system, and his colleagues tried to use a series of fast pulsations of visible light to achieve information transfer between the car and the car. The pulsation of this LED flash is so short that the human eye can't wipe it, but it can provide other cars with information about traffic conditions along the way, possible collisions, and can become part of an unmanned system. Although the data rate of data passing from one car to another is low enough, a common camera can be used to capture it, and LEDs already used in today's cars can deliver this data. VLC is a cheaper option than any new car equipped with radar or laser. While radars and lasers are more efficient ways to make cars aware of the surrounding conditions, they are also an expensive way in price-sensitive markets. To make a basic viable mesh network solution, cars running at least 10 roads need to be equipped with radar or laser systems. VLC relies on line-of-sight, which is a disadvantage compared to radar or wireless networks, because harsh weather and ambient lighting conditions can interfere with LED flashing, which makes VLC less a spontaneous drive technology solution. feasible. However, VLC can provide additional protection for future driverless cars and accelerate its development.
