[01] Wi-Wi Is Wireless Time Sync at 1 nanosecond
At NAB, I found a demo of Wi-Wi STAMP, a wireless time synchronization
protocol that came out of Japan's NICT. Wi-Wi stands for Wireless 2Way
interferometry, and it uses the 900 MHz band for picosecond-level time
sync, and mm-level distance accuracy, in a tiny box, currently the size
of a smartphone. The system is still in development, but existing
prototypes have 20ps of phase synchronization jitter, and time
synchronization down to 30ns. The next generation will have time down
to 5ns in real-world use.
