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.

A method for communicating long messages in a wireless one-way communication system, comprising: transmitting a time division multiplexed data frame which includes both format packets and data packets positioned in specific temporal locations in said data frame, each format packet containing both an address corresponding to an associated receiver and containing pointers to a plurality of data packets each containing a portion of a given long message targeted for transmission to a given receiver; polling the data frame with said given receiver at a first data rate for receiving an initial format packet addressed to said given receiver; and reading said plurality of data packets containing the long message at a second data acquisition rate defined by the initial format packet, the data acquisition rate defined according to temporal locations in the data frame of data packets containing portions of said long message.
