WMM Power Save is a more finely tuned power save mechanism which draws on a variety of tools to manage power consumption. In legacy power save, the driver decided when to transmit data, while in WMM Power Save, the application makes the determination about when to transfer data. This enables customization of the power mechanism to the particular application (e.g., Voice over Wi-Fi, video gaming, etc.). WMM Power Save is backwards-compatible with legacy power save.
