5G: 5th Generation Fixed or Mobile Wireless Radio Access Systems & Networks: Timing - Synchronization

Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time. Systems that operate with all parts in synchrony are said to be synchronous or in sync—and those that are not are asynchronous.

Today, time synchronization can occur between systems around the world through satellite navigation signals and other time and frequency transfer techniques.
 
   

 

Accurate and reliable synchronization in 5G

 

Seamless synchronization operation is fundamental to unlock the full potential of 5G. To efficiently address RAN synchronization requirements, a good understanding of all the technology options for synchronization distribution in transport networks is essential.

Accurate and reliable synchronization has long been a fundamental prerequisite for the correct operation of telecommunications networks and it will be so in 5G. All synchronization requirements for 5G networks are driven from the New Radio (NR) interface synchronization requirements defined by 3GPP. These requirements are not more stringent, but are becoming more essential in 5G than in 4G, therefore seamless synchronization operation is fundamental to unlock the full potential of 5G. To efficiently address RAN synchronization requirements, a good understanding of all the technology options for synchronization distribution in transport networks is essential as the most suitable and cost-efficient sync solution may be different from case to case.

To understand how Ericsson Transport products support synchronization solutions in various positions of the network, Timing Solutions for 5G by Ericsson gives a comprehensive picture of the 5G transport network synchronization landscape, including:

  • an overview of RAN drivers for synchronization,
  • the corresponding transport network synchronization requirements,
  • the transport technology toolbox for synchronization and
  • guidelines on how to find the right solution in various network deployments (both fronthaul and backhaul) using the Ericsson Transport portfolio to reach a reliable, cost efficient and easy-to-monitor synchronization network in transport.
