ABSTRACT:
A point-to-multipoint radio broadcast communication system comprises a directional transmitter focused on a particular one of a plurality of receivers in a linear arrangement, such that the angle between each successively closer receiver and the transmitted beam increases as the distance between the transmitter/receiver pair decreases. Thus, a low-power directional transmitter can effectively transmit to a line of receivers due to the trade-off between a receiver being off-center and its closer proximity to the transmitter.
