Why do communication base stations require PTP time synchronization?

There are various reasons why communication base stations need Beidou satellite PTP time synchronization technology, which mainly boil down to the following points:

Communication base stations need accurate time synchronization to ensure the normal operation of the entire network. In modern communication networks, including 2G/3G/4G and even 5G networks, time synchronization technology is required to ensure the accurate transmission of data between various nodes. Incorrect time information may cause data packet confusion, loss, or repeated transmission, thereby affecting network performance.

5G networks have much higher requirements for time synchronization than previous communication technologies. 5G technology requires the support of technologies such as Massive MIMO (Massive Multiple-Input Multiple-Output), Network Slicing, and Ultra-Reliable Low-Latency Communication (URLLC), all of which rely on high-precision clock synchronization for implementation. Especially for Massive MIMO and URLLC, the time delay must not exceed the nanosecond level.

Beidou satellite PTP time synchronization technology features high precision and high stability. It can provide communication base stations with immediately available time information through satellite signals around the clock and from multiple directions. This is crucial for precise time synchronization between base stations and with the core network.

Beidou satellite PTP time synchronization technology also helps communication base stations achieve accurate fault location and diagnosis. Timestamp-based fault tracking and event logging enable operators to quickly locate and resolve issues, ensuring network stability and continuity.

Therefore, communication base stations require Beidou satellite PTP time synchronization technology to achieve precise time synchronization, thereby guaranteeing high-performance network communication, accurate fault location, and effective network management.
