Precisely synchronized audio, video, and data

Home entertainment systems, automotive infotainment systems, and industrial sensor-based systems rely on precisely synchronized components to deliver optimum results. Wi-Fi CERTIFIED TimeSync™ enables devices to tightly couple with each other through Wi-Fi® connectivity, providing sub-microsecond clock synchronization to ensure the best quality output.

Wi-Fi TimeSync™ supports multichannel audio and video capabilities wirelessly and simultaneously without perceptible drift or lip-sync issues, but its benefits are not limited to audio and video entertainment. Industrial facilities can use Wi-Fi enabled sensors to monitor equipment activity and to time sequential equipment functions for precise output. There are a host of possible industrial, automotive, healthcare, and IoT applications that Wi-Fi TimeSync facilitates by providing tightly-coupled timing to support applications for coordination of Wi-Fi devices.

Standards-based, flexible device synchronization
Wi-Fi TimeSync brings standards-based technology to device synchronization and enables a seamless experience across a variety of components. Multiple wireless speakers, headphones, video displays, and sensor devices can render precision output. Wi-Fi TimeSync operates in both infrastructure and peer-to-peer mode, providing flexibility when Wi-Fi networks are not available.
 
I worked on a project more than a decade ago. Back then we had wished such a feature exist in WiFi standards. The company obviously can't live to see this happen.

Time is the fire in which we all burn, eh?

Oddly enough, I don't think this is a major change to the 802.11 specs - everyone just syncs to the AP...
