Description

With the promise of faster and more reliable mobile networks and an increased number of connections, the implementation of 5G technology requires a higher density of base stations, which can be costly. To make this process more cost-effective, it’s important to optimize spectrum and eliminate connectors, but this requires excellent interference management and synchronization within strict standards. Additionally, the elimination of guard bands between operators presents challenges in avoiding interference. That’s why the use of an over-the-air measurement system like Calnex Sentinel is essential. Calnex Sentinel is equipped with a GPS receiver and rubidium source that provide a time reference to determine the cell id and calculate time errors, making it a critical tool for 5G network testing and deployment.

Key Features and Benefits:

  • PTP, NTP, SyncE and TDM in one box
  • Measure ALL parameters at the SAME time:
    • Network Time Error, network PDV, network Wander (SyncE, TDM) and clock output (frequency and phase)
    • Identify what the issue is and where it’s coming from (network, switch, nodeB etc.)
  • Flexible network connection options:
    • As a pseudo-slave connected to network switches
    • As a network monitor, monitoring live network PDV and Time Error
  • Long-term measurement capability to find intermittent issues
  • Ethernet for control, USB connectivity for external storage
  • Remote operation: VNC or API
  • Embedded GNSS Receiver and high stability Rubidium (Rb) Clock
