Abstract
A limited acknowledgement-based communication methodology increases the throughput efficiency of extended range, wireless packetized data transmissions to a ‘master’ data-reception site from a ‘slave’ data-sourcing site, geographically remote with respect to the data-reception site. Rather than return an acknowledgement for each received packet, the master returns an acknowledgement only after receipt of a group of packets. When returning an acknowledgement, the master identifies which packets of the group were not successfully received. Missing packets may be retransmitted by the slave transmitter either immediately, or in response to a subsequent poll by the master.
