2. Eliminationofdetectionofspecificfalseradartypesbyblockingdetectionoffalseradars
ofaspecifictype.Therearethreetypesofradars:
•Fixed:Falseradarswithfixedpulsewidthhavingfixedre petitionfrequency
•Variable:Falseradarswithvariablepulsewidthhavingvariablerepetitionfrequency
•Staggered:Falseradarswithvariablerepetitionfrequencywithinaburstperiod
(Appliesto5.4GHzETSIonly)
FCC/IC5.4/5.3GHzLinks:Background
TheFCC/ICregulationfor5.4/5.3GHzallowsunlicensedwirelessdataequipment,provided
thatitdoesnotinterruptradarservices.Ifradaractivityisdetected,theequipmentmust
automaticallychangefrequencychannel.ThisfeatureistermedDynamicFrequencySelection
(DFS).Accordingtothestandard,achannelwithactiveradarisprohibitedfromusefor30
minutes.Beforeusingachannelfortransmission,theradioequipmentmustprobeitforradar
signalsforaperiodof60seconds.
RADWINradioproductssupportDFSaswellasACS.
AnimmediateconsequenceoftheFCC/ICregulationfor5.4/5.3GHzisthatthemethodoflink
installationisslightlydifferent.
First,ACScannotbedisabled:
Note
TheFCC/ICregulationsfor5.4GHzbandrequiresthefrequencyrange5600
–5650MHztobebannedfromuse.TheFCCregulationfor5.4GHzband
requiresthatwithin35kmradiusfromany(TerminalDopplerWeather
Radars)TDWRlocationthefrequencyrange5570–5680MHzshallbe
bannedfromuse.
Followtheinstructionsinthelastsectionofthischapter.
