Abstract
A multiple transmitter wide area communication system comprises a central station having a plurality of acknowledge back receivers, each receiving acknowledge back responses on one of a plurality of acknowledge back channels, and a plurality of transmitters each transmitting on an individual channel. The system further comprises a plurality of remote stations each having an acknowledge back receiver which is capable of selectably receiving acknowledge back responses on each of the individual channels, and a transmitter which is capable of selectably transmitting on each of the individual channels. Each central station transmitter substantially simultaneously transmits at a high data bit rate on each individual channel the addresses for acknowledge back pagers for which messages are intended, and further transmits at a high data bit rate the associated messages intended only for those acknowledge back pagers which responded with an acknowledge back response. The central station then transmits at a high data bit rate on a preselected channel, in a predetermined sequence, to the remote stations the addresses and messages of only those acknowledge back pagers failing to respond to the …
