APSD), module can close Wi-Fi Modem and stop CPU to save power. For example, at DTIM3, keep up

sleeping at 300ms, it would receive the Beacon package from AP after each 3ms, then the whole average

current is about 0.9mA.

③ Deep-Sleep mode is applied to the case that Wi-Fi is not necessary to connect all the time, just send

a data packet after a long time (e.g., transmit one temperate data each 100s) . it just need 0.3s-1s to

connect AP after each 300s, and the whole average current is much smaller 1mA.
