A novel application for wireless communications in vehicle early warning

A novel application of wireless communication in vehicle early warning is introduced. This application establishes an innovative function for mobile handhelds that is the protection of their holders from accidents with cars. Two main components of this vehicle early warning system are a mobile base station (MBS) deployed in vehicles, and a transceiver installed in mobile handhelds that defines mobile handhelds as active targets. The MBS: (a) communicates with all mobiles located in its proximity; (b) discriminates the mobiles via unique codes assigned to each mobile; and (c) locates and tracks those mobiles. An early warning signal is generated in critical conditions that triggers or controls mechanical systems such as brakes, wheels or airbags. This paper discusses the structure and design problems associated with this system. This scheme highly enhances road and pedestrian safety and defines a new application for wireless systems.
