A communications system and node for its use therein relates to a communications system and network wherein communications links between subscribers are established by retrodirective oscillating loops between each subscriber and a node station. Means are also created for the establishment of links between nodes so that remotely located subscribers can communicate. Information is transmitted between subscribers by using a mixing process in the node whereby the information transmitted by one subscriber to a node is transferred to a carrier signal transmitted between the node and another subscriber.
