Abstract
A radio data communications system is disclosed in which messages, normally lost to interference caused by independent remote units contending for the radio channel, may be salvaged. If a remote unit communicating a message to a fixed site is interrupted by a second remote unit having a stronger radio signal, the fixed site detects the increase of radio signal strength and activates a synchronization detector which responds to a synchronization data bit sequence which precedes each data message. If the synchronization sequence is detected, the remainder of the first remote data unit message is discarded and the message of the second remote data unit is processed.
