The rapid growth of the internet of things (IoT) makes network timing an urgent issue. As more and more devices come online, synchronization becomes critical and with many emerging applications demanding far more accuracy, it’s important that precise timing can be ensured right across the network ...

Financial markets are currently governed by strict rules; one of these being the requirement to record when a deal has been brokered. Typically, the finance industry has logged this by day, date and time. However, new rules to be introduced in 2018 will mean much more stringent parameters are put in place ...

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 ...
