Nanosecond Global Time Synchronization Network PrecisionTime Receives ITU Approval: 5G/6G Base Stations and Autonomous Driving Achieve Sub-Nanosecond Synchronization for the First Time

Nanosecond Global Time Synchronization Network PrecisionTime Receives ITU Approval

On October 28, 2030, the International Telecommunication Union (ITU) officially approved the PrecisionTime global high-precision time synchronization network standard. PrecisionTime distributes nanosecond-precision time signals from atomic clocks through existing fiber optic networks, providing a unified time reference for 5G/6G base stations, autonomous driving systems, and financial trading systems.

Current GPS timing precision is approximately 10 to 50 nanoseconds, which is sufficient for most applications. However, 5G network carrier aggregation, autonomous driving multi-sensor fusion, and high-frequency trading timestamps require precision below 1 nanosecond. PrecisionTime elevates precision to the sub-nanosecond level through fiber optic time-frequency transfer technology.

PrecisionTime's architecture overlays a time signal transmission layer on existing fiber optic backbone networks, using bidirectional optical amplifiers to compensate for propagation delay variations in the fiber. Each city's timing node connects to the nearest atomic clock source through redundant fiber paths.

The chairman of the ITU PrecisionTime Working Group stated: "Time synchronization is the invisible backbone of digital infrastructure. PrecisionTime will ensure that critical systems remain synchronized at sub-nanosecond precision."

PrecisionTime is expected to begin commercial deployment in 2032. Multiple telecommunications operators and autonomous driving companies have indicated they will integrate the PrecisionTime standard into their infrastructure.
