It is developed from adhoc network and is one of the key technologies to solve the "last mile" problem. In the process of evolution to the next generation network, wireless is an indispensable technology. Wireless mesh can communicate with other networks. It is a dynamic and extensible network architecture, and any two devices can keep wireless interconnection.

Mesh networking needs to comprehensively consider channel interference, hop number selection, frequency selection and other factors. This section will take WLANMESH based on 802. 1 1s as an example to analyze various possible networking schemes. The following focuses on the analysis of the scheme and performance of single-frequency networking and dual-frequency networking.
