LiFi system with outstanding coverage angle for robust vehicle to vehicle communication. The light-based approach enables vehicles to transmit data at high rates while moving and is robust against jamming & hacking.
Technical Background
The optical wireless communication system from Fraunhofer HHI is optimized for an extremely large coverage. Thereby it can realize high speed data communication in an significantly extended area and allows for a high degree of mobility. The lightbased LiFi system can be used in harsh industrial environments and is especially well suited for vehicle to vehicle communication.
Due to the large coverage angle of more than 120°, vehicles can communicate with a stable connection at high speeds while moving. Using light-based instead of commonly used radio-based systems enables a robust hacking-, jamming-, and interference-free transmission.
