In this mode, the STA automatically switches between active and power-save mode. When the STA is connected in idle mode and has no need to send or transmit any data, the STA is in power-save mode. However, if the STA must perform any activity in the network, such as receiving traffic, it sends a null data frame with the power save bit off. Thus, the STA is in active mode from that point until the activity has been finished. After a pre-configured amount of time, the null data frame with the power save bit on is sent to the access point, and the STA returns to power-save mode. This ensures a balance between power consumption and best performance.
