TheFademarginistheminimumrequiredforline‐of‐sight(LOS)conditions.For
degradedlinkconditions,alargerFademarginshouldbeused.Again,itisnotavail‐
ablewhenusingAdaptive Rate.
TheEIRPiscalculatedindBmandWatts.
8.TheRateitemmaybeusedforcalculatingtheLinkBudgetunderbestandworst
scenarios.ItisalwayssettomaximumunderAdaptiveRate.

Alternatively,youmayenterthelatitudeandlongitudeofeachsiteinthelink,in
whichcasethedistancebetweenthemwillbecalculatedanddisplayed.
