7.13 FADE MARGIN MEASURE
In ALFOplus is available the Fade Margin Measure. The Fade Margin is the difference between the Received
Power and the Threshold at a given BER. Once the link is planned, in the Link Budget is present a Fade
Margin that has been calculated through mathematical formulas. The Fade Margin depends from the prop-
agation’s parameters and from the presence of interferers.
This feature is useful to compare the Fade Margin provided from the Link Budget calculation with the real
Fade Margin present on field. Especially in case of interferers that have not been considered during the
planning of the MW link.
In order to execute the Fade Margin measure it necessary to have:
• Theoretical Fade Margin from Link Budget calculations
• Local and Remote IP Addresses.
