Abstract
A vehicle having a plurality of antennas each in association with a communications transmitter device disposed within the vehicle to thereby provide multiple signal transmission sites. At least one antenna is disposed substantially at a top site of the vehicle and at least one antenna is disposed substantially at a bottom site of the vehicle, thus providing antenna coverage irrespective of the spatial orientation of the vehicle. The invention includes a communications system employing a multiplicity of antenna sites as well as methodology for providing a communication link from a vehicle to a receiving site by incorporating the communications system. In this manner, vehicle occupants are provided with a communications link from the vehicle, irrespective of the position of the vehicle. Thus, if one antenna is shielded from transmission because it is situated at a top site of a vehicle and the vehicle is upside down because of a mishap, another antenna which is situated to be operable from a non-shielded site (e.g. a bottom site of the vehicle) will provide effective signal transmission. The invention thereby provides enhanced safety and security for vehicle occupants in most travel environments.
