The disclosure is related to a method and a system for long-distance full-duplex wireless communication. The system is mainly composed of a control circuit, at least one wireless transmission module and one or more wireless gateway modules. The wireless gateway module can receive data from a terminal node via one of multiple channels. The control circuit instructs a wireless transmission module to transmit data. The system utilizes the wireless transmission module to deal with the data from the gateway modules. In the method, in order to achieve full-duplex communication, the system obtains transmission parameters of every terminal node, sets up a transmission schedule with respect to signals having various frequencies within designated time slots according to the operating environment of the node, assigns a transmission priority within the time slots and stores the setting in the node.
