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.
9.Iftherequiredrangebetweenthetwolinksitesisknown,youmayenteritdirectly.
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.
