Dynamic frequency modulation method based on MCS value

The invention discloses a dynamic frequency modulation method based on an MCS value. The method comprises the following steps: a wireless access point configures a frequency modulation list and an MCS threshold; the wireless access point sends the frequency modulation list to a client, and the client updates a local frequency modulation list of its own after receiving the frequency modulation list; the wireless access point detects and counts the MCS value; the wireless access point sends a frequency modulation instruction to notify the connected client; the client immediately sends an ACK message to the wireless access point after receiving the frequency modulation instruction and automatically switches the frequency point to the next item of the frequency modulation list; the wireless access point and the client switch to a new working frequency point at the same time; and the wireless access point sends a heartbeat detection instruction to the client. According to the dynamic frequency modulation method di
