You can use the Uhana by VMware machine learning to determine the cause of external uplink interference.

This topic describes the steps to view data on the Alerts page to find specific symptoms, like poor voice quality, and view root cause and impact analysis data.

Sometimes the use of illegal jammers working in another spectrum can cause external uplink interference which stops them from decoding the network. Antennas can leak into the spectrum and cause interference. Also certain DMI cables can cause leaks.

  1. Select Focus on the main menu. The Alerts page displays with the map showing any red alerts indicating problems. There is also a dashboard summarizing current alert details and a table with alert details.
  2. Use the selection panel to focus the data based on cells, enodeBs, ISMI, and presets. Also set the time range and click APPLY.

  3. Find the alert detail column of interest and click the Visibility icon to view alert details.

    The root cause, if known, is displayed. In this case it is Uplink Interference Unknown.

    The Uplink Interference - PRB Heat Map helps to determine interference levels.

    Other charts highlight lines where the problem exists. Time-series charts such as Agg Throughput, Avg PUSCH/PUCCH Interference, and so on might be available for review.
