Q1:WhichAPisbestformanufacturingandwarehouseareas?

A1:Ingeneral,theAP2600eortheAP3600eisthefirstchoicebecausetheseexternalantennamodels
havethehighestoperatingtemperaturerange‐20to55°C.TheAP1600canalsobeusedbuthasa
slightlyloweroperatingtemperature‐20to50°C.Iftemperatureisnotaconcern,useaninternal
antennamodel(AP1600i,2600i,and3600i).

Q3:WhichAPisbestforhigh‐densitydeployments?

A3:BoththeAP2600andtheAP3600havevirtuallyidenticalAPdensityforcoverage‐baseddesign.
Capacity‐baseddesign(smallercells)yieldsaslightlyhigheraveragecellcapacitywiththeAP3600when
using3SSdevicesandyieldsanevenhigherdensitywhenusingtheoptional802.11acmodule.

Q6:Anyotherthoughtswheninstallingwirelessaccesspoints?

A6:Whendeployingwirelessinstallations,keepthefollowingguidelinesinmind:

 PlacetheAPasreasonablyclosetotheactualusersaspossible.
 Makesureyouhavecoverage(toaknownrequirement),andcompensatefornullsordead
spots,regardlessofwhatproductyouchoosetodeploy.Conductasitesurvey.
 Basetheinstallationsonlessonslearnedfromthesitesurvey.Thebetterthesurvey,theless
likelyconnectivityproblemswilloccur.
 CiscohasanAdvancedServicesteamthatcanperformWLANsurveysorhelpwiththewireless
designifaCiscopartnerisnotavailableorabletodosame.
 Whenpossible,usetheCiscobrandantennaslistedinthisguide.Theyhaveorangebands.
 Donotmountantennasagainstmetalobjects.Antennasworkbestwhenthereareno
obstructionsinthepath.
 TheAP1600,2600,and3600arenotweatherproofandhaveanIPratingof40.
