Optical Wireless Offers Bright Future for Lighter-Weight Cars
University of Warwick scientists are pioneering research into optical wireless ? where data signals travel through light ? and its use in cars. Optical wireless can use just a basic LED, such as those used in torches, to send data. In situations where it?s best for the beam to be invisible, infrared light can be used instead. While optical wireless has been explored for use in aviation for some time, scientists at University of Warwick are leading the way in terms of its use in private vehicles. Inside a car, it can be used to communicate between parts inside the engine compartment, such as between temperature sensors and the engine management system, or between the brakes and the vehicle speed control systems.
