Many of the advanced radio techniques that support the improved user experience in 5G depend on a tightly synchronized network. Without very tight alignment, densely deployed radio towers that 5G requires will interfere with each other, negatively impacting end-user satisfaction.
To help meet the taxing network synchronization challenges required by 5G technology, the ITU-T has defined enhanced accuracy classes for boundary clocks and end points for 5G applications. The time error produced by Class C boundary clocks must be less than 10ns, and less than 5ns for Class D clocks. Qualifying synchronization networks with this level of accuracy will require not only a highly precise measurement device, but also an exceedingly accurate and stable reference device – exactly what the TEM V2 delivers.
Beyond delivering the foundation for a highly accurate measurement, the TEM V2 also provides the best-in-class holdover time. Holdover time is most essential for field deployment as majority of field measurements are done indoors without line-of-sight to the Global Navigation Satellite System (GNSS).
With the TEM V2, mobile operators can test network synchronization to the nanosecond accuracy levels required by the new Class C clocks for hours without leaving an indoor environment for GNSS synchronization.
