FIELD: physics, communications.
SUBSTANCE: invention relates to a method of transmitting messages with resolution of access conflicts and a system for realising said method. The method, which employs messages sources, includes sending messages to a receiver and returning therefrom optical signals separately for each message source over a wireless channel at two frequencies; signals at the first frequency are pulsed and are used to transmit messages from a message source to the message receiver; signals at the second frequency are transmitted and subsequently modulated with signals at the first frequency, then returned to the message sources and received by the receiver from all message sources. A message source detects an access conflict based on superposition of received signals and sends a signal for switching to access conflict resolution.
EFFECT: preventing delay of non-conflicting messages.
