Anritsu Podcast, 5G RAN

5G transport deployment uncovers new challenges within every element of the network – core, transport, and radio access network (RAN) – when transitioning from 4G to 5G. It will also change the fiber optic technology that serves as the backbone connecting it all. Service providers, data center management, and technicians responsible for the deployment, installation, and maintenance of these networks will need to consider synchronization and performance issues and solutions.

Testing capabilities to meet 5G standards and performance metrics need to be efficient, easy to use, and versatile enough to address maintenance of existing 4G infrastructure and achieve 5G network KPIs with optimal deployment, installation, and operation. The importance of fiber will continue to grow in mobile fronthaul, as expanding 5G use cases require greater network speed.

To achieve faster data speeds and higher bandwidth associated with 5G, millimeter-wave (mmWave) bands will be utilized. The consensus is to distribute timing via the RAN using Precise Timing Protocol (PTP) as defined by IEEE. PTP is utilized for synchronization of frequency and phase.

In this podcast, we will discuss the 5G RAN drivers that have an impact on transport test requirements such as network timing and synchronization, timing methods that are used for 5G RAN, and PTP synchronization failures and how to prevent them.

Maintaining synchronization quality will help ensure your network meets 5G latency requirement.

Topics of discussion:

  • 5G time and synchronization challenges
  • Network timing and synchronization impact on 5G NR
  • New LTE-A and 5G features dependent on tight time and phase synchronization
  • 5G’s wide use of TDD spectrum
  • What new timing protocols are required
  • New standards and solutions that are evolving for 5G transport
  • How operators implement these requirements within new RAN architecture
