Figure27‐9:Rateselector
TheRateshown,definestheair‐interfacerateinMbps.ThesystemoperatesinTDD
modeandhastheoverheadoftheair‐interfaceprotoco.lThus,theEthernetactual
throughputisprovidedbytheEthernetRate.
TheFademarginistheminimumrequiredforline‐o‐sight(LOS)conditions.For
degradedlinkconditions,alargerFademarginshouldbeused.
TheEIRPisgivenindBmandWatts.
6.Iftherequiredrangebetweenthetwolinksitesisknown,youmayent er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.

Climatefactorlist.Bothofthesequantitiesarecalculated.
Note
Foragivenair‐rate,Ethernetthroughputwilldecreasewithincreasingrange
duetopropagationdelay.
