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).

Q2:Whatif IaminacountrywheretheregulatoryagencymaynotapprovetheAPtobeusedoutdoors
becauseofUNII‐1bandrestrictions?WhatifI
wishtousehighergainantennas?

A2: Consider the Cisco Mesh products (1550 Series) or look for access points ending in “P” (for
professionalinstall),suchasthe3502PSeriesorCiscooutdoorbridgingproducts.

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cel ls)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.

Q4:CiscohasanewerPower
Injector(AIR‐PWR‐INJ5).Howisthisdifferentfromthe(AIR‐PWR‐INJ4)?

A4:ThenewerAIR‐PWR‐INJ5isan802.3af(15.4Winjector).Itisalow costinjectorforusewiththeAP
1600 and the AP 2600 and can also be used with  the AP 3600 without
the optional module. The AIR‐
PWR‐INJ4isamorepowerfulinjectordesignedtoworkwiththeAP3600withoptionalmodules.

Q5:CanindustrialwirelessmotionorsmokedetectorscauseWLANinterference?

A5: Yes, some products  such as United Technologies DD475 and Optex MX‐50 operate in the 2.4
GHz
bandasdootherwirelesschimes,cameras,andindustrialequipmentfromothermanufacturers.

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surv eys 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.
