Modem-Sleep requires the CPU to be working, as in PWM or I2S applications. According to802.11 standards
(like U-APSD), it saves power to shut down the Wi-Fi Modem circuit whilemaintaining a Wi-Fi connection with no data transmission. E.g. in DTIM3, to maintain a sleep 300mswake 3ms cycle to receive APs Beacon packages, the current is about 20mA.
:
During Light-Sleep, the CPU may be suspended in applications like Wi-Fi switch. Without datatransmission, the Wi-Fi Modem circuit can be turned off and CPU suspended to save poweraccording to the 802.11 standard
(U-APSD). E.g. in DTIM3, to maintain a sleep 300ms-wake 3mscycle to receive APs Beacon packages, the current is about 2mA.
:
Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long timelags 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 isless than 1mA. 3.5RF Characteristics 3.5.1RF Configuration and General Specifications of Wireless LAN Table-9 RF Configuration and General Specifications of Wireless LAN Items Country/Domain Code Center Frequency Rate 11b 11g 11n HT20 11b 11g 11n 1stream Specifications Reserved 2.412-2.472 2.412-2.472 2.412-2.472 1, 2, 5.5, 11 6, 9, 12, 18, 24, 36, 48, 54 MCS0, 1, 2, 3, 4, 5, 6, 7 Modulation type 11b DSSS Unit GHz GHz GHz Mbps Mbps Mbps Wireless-Tag Technology Co.,Limited http://www.wireless-tag.com 1 0 WT-01E DATASHEET 11g/n OFDM 3.5.2 RF Tx Characteristics Table-10 Emission Characteristics Mark Parameters Condition Min Value Ftx Input Frequency 2.412 Output Power PA output power in 11b mode PA output power at 72.2 Mbps 19.5 15.5 Pout 3.5.3RF Rx Characteristics Typical Value 20.5 16.5 Max Value 2.484 21.5 17.5 Table-11RF Receiving Characteristics Mark Parameters Condition Min Value Frx Input Frequency 2.412 Typical Value Max Value 2.484 DSSS OFDM HT20 Srf 4.
