At present

the working mode of WLAN AP is based on independent access control mode. In this mode of operation

the frequency channel is fixed and the transmission power is constant

which easily causes waste of power consumption and spectrum resources and channel blocking. After in-depth research

the author designed a green Wi-Fi system based on SDPA algorithm through the wireless controller AC ’s intelligent perception and dynamic data analysis of AP

realized the AP’s dynamic power adjustment and intelligent channel selection

which effectively reduced electromagnetic radiation pollution and improved spectrum efficiency.
