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 802.11w
IEEE standard for protected management frames.
No Pause on Suspend
A new feature to enhance the reliability and lower the 9F 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.
D0- 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.
WoWLAN/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.
