What’s new: A reminder of how important PNT from GPS/GNSS is to telecoms. And the more sophisticated the system, the greater the requirement for precise and reliable PNT.
Why it’s important: Our infrastructures tend to be inter-reliant. For example, telecoms need electricity and electrical grid management relies on telecoms. PNT underlies it all. A PNT failure would likely cascade through numerous infrastructures.
What else to know:
- Some telecommunications companies have started providing time to some of their base stations by fiber. That’s a good and important start.
- Broadcast systems can also provide PNT to an infinite number of users, both fixed and mobile without regard to location in the service area.
- Any 5G-based PNT system will still need to have a traceable and robust timing source independent from GPS/GNSS.
Timing is everything: Why synchronization and resilience are critical for 5G’s next leap (Reader Forum)
For all the attention paid to bandwidth, latency and coverage, it is synchronization that quietly underpins much of what will define 5G
The early promise of 5G is giving way to more mature, real-world deployments, and with that comes a deeper understanding of what it really takes to deliver the next generation of mobile connectivity. Across the globe, operators are deploying standalone 5G networks, preparing for 5G-Advanced and looking ahead to use cases that were once just concepts on whiteboards. From autonomous industrial operations to critical communications infrastructure, the expectations of 5G are shifting dramatically. And with those expectations comes one unifying requirement: precise, robust and resilient time synchronization.
For all the attention paid to bandwidth, latency and coverage, it is synchronization that quietly underpins many of the features that will define 5G’s future. In reality, the level of precision and network reliability needed to unlock these features represents a major shift from the relatively forgiving architectures of earlier mobile generations. Operators are quickly learning that yesterday’s timing strategies, especially those dependent on fragile GNSS (Global Navigation Satellite System) infrastructure, are no longer sufficient for what lies ahead.
