This tutorial, briefly explains you about the power save mechanisms supported in 802.11 protocols.
This presentation is prepared assuming that readers have basic knowledge of WLAN protocol and its operation. So, let's start the tutorial.
Do you know that 802.11 protocols support multiple methods of power saving mechanism for wireless stations? From my experience, I can guess that most of you are not aware about all the types and number of power save mechanisms supported by 802.11 protocols? If that is true, then this tutorial is the right one and worth taking a look at the presentation.
