Abstract (en)

[origin: WO9603010A1] A receiver operates in both a first polling protocol and in a selectable data acquisition protocol to both conserve power while quickly read long messages in wireless one-way communication systems. The receiver first polls data transmissions at a relatively slow periodic rate to identify messages. When the receiver identifies a corresponding address in the data transmission, a format packet directs the receiver to acquire data using a second data acquisition protocol independent of the polling protocol. The data acquisition protocol enables long messages to be communicated in a fast, highly reliable manner. After the long message is successfully transmitted, the receiver automatically reverts back into a polling protocol to conserve power.
