7.Determinethegroundandlightningconnectionpointsoftheinstallation.TheODU
andPoEmustbothbegrounded.
8.UsingtheOhmmeter,measureandrecordtheresistanceoftherequiredinstallation
tothegroundingpoint.Theresistancemustbelessthan1Oohm.
9.Reviewtheresultsofthephysicalsitesurvey.Decideifthesiteissuitableforthe
wirelessnetworkinstallation.
• Ifthesiteissuitable,continuewithstage3,theRFsurvey
• Ifthesiteisnotsuitable,surveyanothersite
AdditionalOutdoorSiteRequirements
Theambientoutdooroperatingtemperatureshouldbe‐35to60C(‐31to140F).
AdditionalIndoorSiteRequirements
Theambientoperatingtemperatureshouldbe0to50°C(32to122°F)atahumidityofupto
90%,noncondensing
Stage3:RFSurvey
TheRFsurveyexaminesthewirelessenvironmentoftheinstallationsite,todetermine
whetherthereareavailablechannelswithintheradiooperatingfrequencyband.AnRF
surveyisperformedusingaspectrumanalyzer.
Itisadvisabletofamiliarizeyourselfwiththespectrumanalyzerbeforegoingoutonsite,
specificallytheMaxHoldandMarkerfunctions.
YoushouldperformtheRFsurveyateachoftheproposedsectorsites.
Thesurveyshouldbecarriedoutduringabusytimeofday,tobestjudgetheworst‐caseradio
inte rference.Allow2‐4hoursdurationforagoodRFsurvey.
RFPlanningforDenseInstallationsand
CollocatedSites
Interferencemayarisefrom
• 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channelforeachcollocatedRADW INunit.
