Ensuring Precise and Robust Network Timing with GNSS Test Solutions

Learn about the testing requirements and solutions around modern network time synchronization


Times are changing in the world of telecommunication networks. To meet demand for high-speed, high-bandwidth services, network operators are seeking to roll out next-generation LTE-TDD and LTE-A networks. But for these new networks to deliver a quality service with no dropped packets, they need highly precise time and phase synchronization across the network.

Time synchronization begins with the Primary Reference Time Clock (PRTC) or Grandmaster Clock; a device whose job is to sync continuously to Universal Coordinated Time (UTC) – most commonly obtained from a global navigation satellite system (GNSS) like GPS or GLONASS – and distribute precise time to all other devices in the network.

The webinar deals with the testing requirements and solutions around modern network time synchronization. A simple test setup can address the needs and help you to improve the performance and reliability of your timing solution.

You will learn:

  • Why precise timing is so important in next-generation LTE networks

  • Time errors and test recommendations (ITU-T G.8272)

  • Potential sources of GNSS signal interference

  • Testing challenges, and how they can be overcome
