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.
