  • Wi-Fi communication technology In Wi-Fi communication technology, a device (STA) idle listening channel wastes a lot of power. In order to reduce the energy waste caused by the idle listening channel of the device, Wi-Fi technology introduces a dormancy mechanism, that is, the Wi-Fi module (Wi-Fi interface) of the device goes to sleep without data transmission and turns off the receiving transmitter. The traditional Wi-Fi sleep mechanism can reduce the power consumption of the Wi-Fi module. However, if one STA's Wi-Fi module is in a dormant state, the access point (AP) cannot send data to the STA, and the AP needs to wait until the STA's Wi-Fi module wakes up. This will increase the communication delay and will not enable on-demand real-time data transmission.

  • the STA In order to reduce the communication delay caused by the traditional Wi-Fi sleep mechanism, the STA usually follows a certain sleep mode and periodically wakes up to check whether the AP has data to transmit to the STA.
