Problems solved by technology

[0003] The current wireless local area access network (WLAN) is basically: a central switching cellular distributed local area network and a wireless single-hop star structure wired AP accessing a wireless local area network (such as a WiFi wireless local area network). It is necessary to carry out large-scale hole-laying construction in the completed underground power station to arrange access to APs, and complex network debugging is required. Once a wired access point in the network fails, the wireless communication in an area will be interrupted. Once the network coverage area needs to be changed, it is necessary to carry out wiring construction, and it is difficult to change the network topology structure. Once multiple users access a wired access point, it will cause communication congestion at the node.
