Features required for AOAC Power Management Feature Description Wi-Fi Direct A peer-to-peer connectivity solution that builds on today’s AP/STA Wi-Fi CERTIFIED™ devices and Internet access Wi-Fi technology. Helps improve device connectivity experience. Connection Manager A light weight cross media connection engine for effortless connection management. Radio Management Software radio ON/OFF controls for different media types. WPS 2. 0 Windows support WPS 2. 0 which enables faster discovery of devices and better interoperability. IEEE 802. 11 w IEEE standard for protected management frames. No Pause on Suspend A new feature to enhance the reliability and lower the 9 F failures. Wi-Fi Auto PSM Windows will support the Wi-Fi Power Save Mode. USB Selective Suspend Windows will natively support USB selective suspend for USB interfaces. D 0 - Packet Coalescing A coalescing scheme for cutting down the impact of noisy traffic on system power consumption. Network List Offload A feature to offload certain network hints to NIC to optimize power efficiency and connectivity. Wo. WLAN/Wake Packet detection (WPD) A feature to remotely wake the sleeping machine as and when needed. It will help system to sleep and at the same time be reachable. WPD will track the reason of wake.
