Wireless Power Save Polls
Displays the number of Power Save Polls transmitted or received by the device. Stations transmit a Power Save Poll (PS-Poll) when they wish to enter the sleep state to conserver power. The PS Poll informs the AP how long the station will be unavailable, allowing the AP to buffer data accordingly.
A Power Save Poll is a Control Frame sent by a station after awakening from a power-saving mode. It is sent to the AP to receive any frames that may have been buffered while it was in power-saving mode.
