"Wi-Fi CERTIFIED TimeSync" that enables advanced timing synchronization on Wi-Fi will be announced

ByChris Oakley

Wi-Fi Alliance, which formulates the Wi-Fi standard, announced on January 5, 2017, a technology capable of synchronizing the time axis among multiple Wi-Fi devices "Wi-Fi CERTIFIED TimeSync(Hereinafter "Wi-Fi TimeSync") at the venue of the technology trade fair "CES 2017".

This standard is to synchronize the timing between multiple Wi-Fi devices precisely with millisecond accuracy or less by placing a sync signal on Wi-Fi radio waves. It is a function not found in the conventional Wi-Fi, and by synchronizing the timing, it is possible to process data at almost the same timing on multiple devices.

As a result, for example, even a plurality of speakers installed at remote locations can be sounded at the same timing, so in the home theater, the signal to the surround speaker is skipped by Wi-Fi, the timing is adjusted with high accuracy It is possible to use such as realizing high sound quality by playing sound. Also, it is possible to synchronize the timing of sound of multiple channels, and to synchronize with video. Furthermore, by synchronizing the timing, problems such as "jirisiri" such as jitter noise, delay in pronunciation, "echo" in which sound repeats are also solved.

It is Wi - Fi TimeSync which is expected to be mainly used for entertainment for home use, but it is thought that benefits are also present in industrial and other fields. As the time setting of multiple devices can be matched in detail, Wi-Fi Alliance offers advantages when it can be applied to realization of IoT (Mono's Internet), medical site, industry, and automation technology improvement .

The time when devices that support Wi - Fi TimeSync appear is unknown at the time of article creation, but it is expected that it will be extremely convenient if it becomes possible to solve scenes where physical cables were needed by radio It seems likely to be able to say. We are waiting for the earliest announcement of compatible equipment.
