If thereis no data transmission while maintaining a WiFi connection, the WiFi Modem circuit can beswitched off and the CPU is powered down according to the standard (eg U-APSD). Forexample, at DTIM3, every sleep 300 ms, wake up 3 ms to receive AP's Beacon packets, etc., theoverall average current is about 2 : Deep-Sleep is used for applications that do not have to keep the WiFi connection for along time, such as a sensor that measures the temperature once every 100 seconds.
