Link Budget Calculation report

Link Budget Calculation report overview

The Link Budget Calculation report provides the details on radio link deviations, based on the Install/Design and Actual RSL values per MPT/UBT basis, for selected time range and granularity. The report lists the number of deviations and details on the links for Actual vs Design and Actual vs Install dB values.

The default display is a set of tables for 1+0 and 1+1, 2+0 and 2+2, and N+0 and N+N radio links providing details including Site A, Site B, Radio Link Name, Link Distance (km/mile), Site ID, Port, Design RSL (dBm), Installed RSL (dBm), Actual RSL (dBm), and Number of deviations for the selected inputs.

Click on the number of deviations on the selected radio link to drill down to the Link Budget Calculation details report. The default display is a time-series chart with Actual vs Design and Actual vs Install dB values. The values are plotted on the time slots in the time range and presented in a table with details like Date, Time, Actual vs Design RSL deviation, and Actual vs Installed RSL deviation.

Note: The coordinates are displayed as parameters on the General tab of the Node Properties form.
