maintaining a Wi-Fi connection with no data transmission. E.g. in DTIM3, to maintain a sleep
300ms-wake 3ms cycle to receive AP’s Beacon packages, the current is about 15mA
2
During Light-Sleep, the CPU may be suspended in applications like Wi-Fi switch. Without data
transmission, the Wi-Fi Modem circuit can be turned off and CPU suspended to save power
according to the 802.11 standard (U-APSD). E.g. in DTIM3, to maintain a sleep 300ms-wake 3ms
cycle to receive AP’s Beacon packages, the current is about 0.9mA

Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long time
lags between data transmission, e.g. a temperature sensor that checks the temperature every 100s,
sleep 300s and waking up to connect to the AP (taking about 0.3~1s), the overall average current is
less than 1mA.
