Sync performance on the air interface is finally revealed

Ensuring accurate synchronization on the air interface is a complex task that presents numerous challenges. Fortunately, the Calnex Sentinel with Over-the-Air Time Error capability provides a solution to address these challenges. This innovative solution is the only one available that enables network testing to meet the strict ±1.5µs ITU-T standard for both FDD and TDD bandwidths, ensuring precise synchronization.

However, small cells like Pico, Femto and Macro cells present unique challenges when it comes to measuring Time Error. These cells do not have 1pps outputs, which makes it particularly difficult to measure Time Error accurately. As a result, over-the-air measurement with Calnex Sentinel becomes the only feasible option to ensure accurate synchronization on these small cells. It’s important to note that the lack of 1pps outputs in these small cells makes it impossible to use other conventional measurement methods, further emphasizing the critical role of Calnex Sentinel with Over-the-Air Time Error capability in network testing and synchronization.

  • Output 1pps TE
  • Input/output SyncE Wander and ESMC decode

Wireless networks are designed to provide a seamless experience for users by ensuring that all services are synchronized and working as expected. The 3GPP standard specifies that there should be no more than a 3µs phase difference between two air interfaces to keep the network synchronized. This standard helps to ensure that the network runs smoothly and all the services work correctly.

However, despite this standard, wireless networks are not perfect, and there are many factors that can affect the timing and synchronization of the network. These factors are known as impairments, and they can have a significant impact on the performance of the network. Some common impairments include interference from other devices, variations in temperature, and changes in the physical environment. When these impairments occur, they can cause the timing and synchronization of the network to be thrown off, leading to issues with service quality and reliability.
