Abstract
A system and process for continuous reception of information by a mobile receiver unit passing among a plurality of spaced transmitters with each transmitter configured to individually transmit signals to the mobile receiver unit. The mobile receiver unit has a pair of scanning receivers controlled by a switching control module. The module causes one of the scanning receivers to lock onto signals transmitted from one of the transmitters while causing the second scanning receiver to scan signals transmitted by the transmitters in the reception range of the scanning receiver. Once the strength of the signal locked onto by the first scanning receiver falls below a predetermined minimum signal strength, the second scanning receiver locks onto the best suited received signal and the first scanning receiver is caused to commence scanning, the roles of the scanning receivers thus being reversed. The process continues, with the roles of the scanning receivers constantly being reversed, as the mobile receiver unit traverses the signals broadcast by the plurality of spaced transmitters.
