Wi-Wi is wireless time sync at 1 nanosecond | Hacker News

Hacker News discussed Wi-Wi, a wireless time-synchronization approach that claims nanosecond-level precision.

The post contrasts it with ordinary networking gear, which is usually only accurate to microseconds unless it truly supports PTP in hardware.

It highlights how hard reliable sub-microsecond timing is without specialized switches or clocks such as boundary clock and transparent clock devices.
