Whoneedsit
IfyouareusingDFSfrequencybands5.3/5.4GHzETSIand5.4/5.8GHzFCCyoushouldusethis
facility.
DFSandFalseRadarMitigation
AboutDFS
UnderDFSfrequencybands,itmustbeensuredthatradiolinksdonotinterferewithcertain
radarsystemsinthe5GHzband.Ifradarisdetected,theradiolinkshouldmove
automaticallytoafrequencythatdoesnotinterferewiththedetectedradar.
WhatisFalseRadarMitigation
FalseRadarMitigationcapa bilityisanadvancedmethodtoreduceoreliminatefalseradar
detectionandDFStriggering(“Falsepositives”).
Falseradardetectioncanbecausedbyotherradiostransmissionsorexternalinterference
thatcanbeinterpretedastrueradar.
ThisoptionisactiveonlyinDF Sfrequencybands,5.3/5.4GHzFCCforSiteAonlyand5.4/
5.8GHzETSI,botesidesofthelink.
Inwhatfollowsfalseradarmeansanysourceofradar‐likesignalswhicharenotrealradar.
FalseRadarMitigationhastwo components:
1. Reductionoffalsepositiveradardetectionbyreductionoftheprobabilityofdetectingany
kindoffalseradars,whileallowingthesystemtodetectrealradarsignals.
