In the existing Mesh device communication method, the communication link between Mesh devices, namely the backhaul link, is either wired or Wi-Fi 2.4G or Wi-Fi 5G/6G, and 2 links cannot transmit data at the same time. Therefore, the bandwidth of the MESH device is difficult to fully utilize in the prior art, so that the internet access bandwidth on the slave device is often limited by the bandwidth of the backhaul link, and the problem of low traffic throughput of the wireless communication device exists.

Wherein the step of dividing each backhaul link into different environmental interference levels based on the current received indication signal strength and transmission rate of each backhaul link comprises:
step S21, obtaining the current receiving indication signal strength range and the transmission rate range corresponding to each environmental interference level;
step S22, dividing each backhaul link into different environmental interference levels according to the current received indication signal strength, transmission rate, current received indication signal strength range corresponding to each environmental interference level, and transmission rate range of each backhaul link.
