Figure 3: Power Save Mode1 after Connection to an AP
3.3.3 Power mode 2
The RS9110-N-11-2X module puts to sleep the Baseband and RF components in
this mode. The Core Control block interacting with the Host is always functional.
Hence, the module can receive commands from the host at any time and there is
no SLEEP-ACK message exchange with the Host.
NOTE: The average current consumption in Power Mode 2 is higher than
Power Mode 1.
