In recent years, there are many researches and applications on establishing wireless network monitoring around the private network of power supply station area, but most wireless communication methods transmit a small amount of data. In this paper, mesh networking is the core, and it is studied and analyzed. On this basis, combined with the changing law of service characteristics and network delay characteristics, the network performance of single and dual-frequency networks in mesh networking structure is studied, which provides a theoretical basis for the research of network design, and the efficient mesh networking mode in wireless communication in power supply area is adjusted accordingly with the changes of environment and load, thus constructing an ideal mesh network scheme. In the throughput of Mesh cluster, the throughput of Mesh Device A is twice that of single AP.
