Synchronizing distributed network architecture is a major challenge. Highly accurate phase delivery at aggregation sites is becoming more and more vital with the growth of IoT and the emergence of 5G applications. But the aggregation site can be a tough environment for grandmaster clocks. Firstly, it requires timing technology with new levels of power, size and cost optimization, integrated with a highly scalable network management system. Grandmasters need to be ruggedized and able to operate in wide temperature variations. And, most importantly, they need a backup plan ...

The new “enhanced” primary reference time clock (PRTC) recommendation from the International Telecommunication Union (ITU), G.8272.1, looks set to be one of this year’s key innovations in the world of network synchronization. Aimed at producing the levels of accuracy necessary for 5G, enhanced PRTCs (ePRTCs) go far beyond the current technology. While the time output of today’s PRTCs should be accurate to within 100ns of Coordinated Universal Time (UTC), this new generation of clocks promises to deliver time to within just 30ns. ePRTCs also offer a greater level of reliability – unlike current PRTC technology, which has no holdover specifications, the emerging enhanced clocks are able to hold time accurately for 14 days, ensuring time service performance during GNSS outages ...
