Abstract: A mobil radio communication network utilizing meteor burst communication medium. A master station communicates with a plurality of mobile radio stations using digital messaging. Each of the master stations generates polling data sent over a plurality of sectors to identify mobile radio stations to which messages are to be transmitted. Messages for transmission are composed at the master station, and when an acknowledgement is received in one of a plurality of receive sectors at the master station from the polling command, the messages are subsequently transmitted. Transmission of a message following receipt of an acknowledgement occurs only over a transmit sector containing the received acknowledgement signal. Messages may be composed in each of the mobile radio stations and sent digitally to the master station which responds by sending an acknowledgement over the transmit sector which is coextensive with the receive sector having processed the acknowledgement signal.
