In 5G Technology World's 5G handbook, read about the timing challenges that come with synchronizing 5G networks.
Frequency synchronization in the radio access network (RAN) minimizes disturbances at the air interface, ensures mobile handover between radio base stations, and fulfills legal and regulatory requirements associated with a frequency license.
Radio-access networks (RANs) must minimize disturbances at the air interface. Disturbances in timing can upend synchronization of the radio RAN and ultimately to the downstream network. Strict timing requirements specified in industry standards ensure that base-station handovers occur smoothly and that a wireless network complies with legal and regulatory requirements associated with a frequency license.
