Disaggregated Networking for 5G - What is Needed to Make it Work?

The Open Optical & Packet Transport (OOPT) group is a project group within Telecom Infra Project (TIP) that works on the definition of open technologies, architectures and interfaces in Optical and IP Networking. We looked at a detailed webinar from OOPT here.

The Disaggregated Cell Site Gateways (DCSG) within OOPT works on the definition of open and disaggregated whitebox cell site gateway devices that operators can deploy in their current 2G/3G/4G cell sites, as well as in the upcoming 5G deployments. The team produces technical specifications that define software, hardware and API requirements that represent the needs of mobile network operators and also works with industry partners to develop devices that meet the specifications.

At TIP Summit Latam in 2021, Ulrich Kohn, Director, Solutions Marketing, ADVA presented a talk on Disaggregated Networking for 5G where he looked at disaggregating high-end routers, DCSG, strategies of making white boxes timing aware and finally, disaggregated synchronization solutions.

His talk is embedded below.

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".

Synchronization for 5G: the requirements and the solutions from ADVA

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.
