Wi-Wi is wireless time sync at 1 nanosecond

Wi-Fi STAMP, a Japanese-developed wireless time synchronization protocol, achieves nanosecond-level precision (5-30ns) over the 900 MHz band with millimeter-level positioning accuracy, offering IT organizations a cost-effective alternative to GPS and wired time sync for mission-critical infrastructure like broadcast, financial trading, and distributed systems. This emerging technology addresses the growing need for precise timing synchronization in industries adopting standards like SMPTE 2110, while its superior indoor penetration and wireless range (0.2-5km) reduce infrastructure costs compared to traditional wired or satellite-based solutions. As the technology matures toward production deployment, organizations relying on precise time synchronization should evaluate Wi-Fi STAMP's potential to simplify distributed system synchronization and reduce total cost of ownership.
