Today’s mobile network operators face a more challenging set of decisions than ever before. For many years, frequency synchronization delivered by TDM-based technologies was sufficient for the timing demands of mobile networks. Then came the evolution to packet- and Ethernet-based networks, which required additional features, such as the ability to transport timing information in packets ...

2018 is shaping up to be a big year for our team. With a huge rise in dense small cell deployments and 5G applications edging ever closer, operators are now facing unprecedentedly strict requirements when it comes to ensuring the levels of precision and stability needed in their synchronization networks. That's why we're innovating to meet these major challenges head on and preparing key technology announcements for the coming months ...

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 ...
