Considerations when testing the performance of a T-BC or T-TSC

Boundary clocks and slave clocks are key components in synchronization networks, whether conforming to G.8273.2 for full timing support or G.8273.4 for partial timing support deployments. This presentation will provide an overview of the requirements for each of these, compare some of the metrics defining their performance, and look at why meeting these limits is critical in achieving the required end application behaviour.

5G-NR The challenges and the need for measuring Time Alignment Error OTA

5G promises much in many different market areas and deployment scenarios. Never before has there been so much hype around a new cellular standard. For this to be realized, 5G has to be successfully deployed in many different guises and it all has to be synchronized within a single network and in some cases, across multiple networks. To manage all this in a cost effective manner will require being able to make synchronization measurements over the air. This paper explores some of the differences between 4G and 5G and addresses the challenge of ensuring that intra and inter network timing can be verified.

Proving performance of Fronthaul under different types of network conditions

The advent of 5G has brought new opportunities in areas such as IoT , the automotive sector and medical industry. To enable this there have been significant architectural changes in the shape of mobile networks. We see the introduction of new communication protocols such as eCPRI, as well as new vendors such as those from the O-RAN alliance. This session will examine three areas. We look at the factors that have brought us to where we are now. We examine requirements based on the different standards in play. Finally we discuss the components of a testing methodology looking at each data plane and determining the impact on communications under the range of network conditions which may be found on fronthaul networks.

5G Fronthaul timing challenges including ORAN Relative Time Error and test requirements

This presentation will look at the different fronthaul network architectures being proposed by bodies such as CPRI and ORAN, and the synchronization requirements associated with them. It will cover the four fronthaul synchronization options proposed by ORAN, the performance requirements for each option, and how to test both the individual components and the networks themselves.

Sync over PTS and APTS networks - what is it and what are the testing requirements?

Some operators require to operate synchronization over packet networks that have little or no direct support for PTP (Precision Time Protocol). This is known as “Partial Timing Support” (PTS). This talk describes what PTS is, and the main use cases for it, such as APTS (Assisted Partial Timing Support). It will also look at how to test synchronization both in a network, and for individual network elements.
