Synchronization for 5G - Requirements, Solutions & Architecture

Couple of months back, Oscilloquartz, an ADVA company, announced that BT is leveraging its high-capacity, future-proof Oscilloquartz synchronization technology to bring 4G coverage to previously underserved areas and begin the rollout of 5G services across the UK. Prior to this deployment, BT’s timing network was based purely on frequency synchronization. With the new solution, it can now distribute stable and accurate phase and time-of-day information, enabling BT to dramatically improve the use of its spectrum. The new synchronization network is built on the OSA 5430 and OSA 5440 and integrated with ADVA’s network management solution. The technology provides the sub-microsecond accuracy required for next-generation mobile applications together with hardware redundancy for unbeatable resilience.

At the Small Cell World Summit held earlier this month, Gil Biran's presentation outlined the key synchronization requirements and solutions for mobile networks in the era of 5G. Check out the slide deck embedded below to discover how longest holdover and highest precision can be achieved with the "industry's most comprehensive timing technology portfolio".



This video of OSA 5430, the first high-capacity grandmaster clock available on the market to support PTP, NTP and SyncE over multiple 10Gbit/s Ethernet interfaces is also worth a watch. It's also the first device of its kind to provide redundancy and protection.
