FalseRadarMitigation
Facilities
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capability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
(HBSonly)and5.4/5.8GHz
ETSI(HBS&HSU).
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probabi lityofdetectingany
kindoffalseradars,whileallowingthe
systemtodetectrealradarsignals.
