3.3.4 Fade Margin Calculation
The fade margin is the difference between the actual received signal and the radio’s threshold. Using
the formula provided in Section 3.3.3, the anticipated RSL can be calculated. Compare this RSL to
the specified threshold of the Lynx radios, which is shown in Section 2.2, and calculate the fade
margin as the difference between the two signal levels.
Dispersive fade margin is another factor that many microwave path engineers may use to plan their
link budget. For the Lynx radios, the dispersive fade margin is in excess of 55 dB and therefore is
not a determining factor in path planning.
