RFPlanningforDenseInstallationsandCollocatedSites Chapter3
• SelfinterferencefromcollocatedRADWINradios
• Othercollocatedradiodevicesinstalledonthesamesite.
Toavoidorminimizeinterference,followtheserecommendations:
• ForcollocatedRADWINunits,useanHSSunittosynchronizebetweenthem.Selecta
differentoperatingchannelsforeachcollocatedRADWINunit.
• IfoneormorecollocatedunitsarenotRADWINunits,ensurethatthereisaphysical
separationofatleastthreemetersbetweenaRADWINunitandanyothercollocated
radioonthesite.
• Usethelargestpossiblefrequencygapbetweentheseunits.
• Choosethebestfrequencychannel(asclearaspossibleforminterference).Youmay
havetousetheChangeBandfacilityavailableforallRADWIN2000products.
• Toselectafrequencychannel,movethelinktoInstallationMode(usingSiteconfigura‐
tion)andstarttheInstallationwizard.IntheChannelSettingswindow,usethequality
baratthebottomtohelpyouchooseabetterchannel(clearerofinterference).
• UsetheSpectrumViewtooltofindthebestworkingchannel(Tools|SpectrumView).
• DecreasingtheTxPowerofalinkwillreducecollocationinterference(SiteConfigura‐
tion|AirInterface).
Note
UsetheLinkBudgetCalculatortodeterminetheminimumTxPower
requiredtomaintainlinkstabi lity.
