Abstract
A system and method for collision avoidance within nodes of an Automatic Link Exchange (ALE) network establishes a handshake between transmitting and receiving nodes for a linked call over an assigned frequency band. The transmitting and receiving nodes mutually determine transmission and reception sub-channel vectors within the assigned frequency band, e.g., for calling and response. Before the linked call commences, and when other scanning stations of the ALE network dwell on the assigned frequency band, the transmitting and receiving nodes transmit collision avoidance protocol data units (PDU) identifying the nodes, the transmission and reception sub-channel vectors, and the duration of the linked call such that scanning nodes may prevent interference with the linked call by avoiding transmission over the identified sub-channels.
