Telecommunication

The pain points are concentrated in four major dimensions: accuracy, stability, security, and management. Traditional clock sources lack accuracy and are susceptible to interference

Power Utilities

Strong electromagnetic environments can easily cause satellite timing signals to be interfered with or deceived. Different devices have very different requirements for synchronization accuracy and multi-protocol compatibility is complex.

Rail Transit

Satellite timing is easily obstructed by tunnels, terrain and other environmental interference. The compatibility of multiple devices and multiple protocols is complex, and network delay jitter affects synchronization accuracy.

Finance

Scenarios such as high-frequency trading require extremely high microsecond accuracy. The clocks of distributed system nodes are prone to deviation and network delays affect synchronization consistency.

loT&Smart Building

Devices are highly heterogeneous and multi-protocol compatibility is complex. Delay jitter and clock drift in a mixed wireless/wired network environment can easily lead to synchronization deviations.

Learn More +

Metrology

There are strict requirements for high precision at the nanosecond to microsecond level, while network delay jitter, clock drift and hardware resolution limitations exacerbate synchronization deviations.
