CT520LANforgeWiFIRE802.11a/b/g/nWiFiTraffic
Generatorwith32VirtualSTAInterfaces
TheCT520wirelesstrafficgeneratorisanexcellentchoicefortestingAccessPointsandotherWiFinetworks.The
CT520usesamodifiedWirelessdriverforWiFiNICsbasedontheAtheroschipset.Itcansupportupto32Virtual
Stations.EachoftheVirtualStationshasitsownIPaddress,IPportspace,MACaddressandroutingtable.The
VirtualStationscanbeassignedtocommunicatetoaparticularAccessPoint,useaparticularSSID,andhave
optionalWPA2keyassigned.Moreadvanced802.1Xauthenticationisalsoincluded.ThereisasingleWiFiradio
perCT520butmultipleLANforgesystemscanbeclusteredtogetherformorerealisticradiointerferencepatterns
andincreasedtrafficgenerationcapability.Theradiosupports802.11a,b,gornmode.Transmitpowerand
channel/frequencyisconfiguredonaper-radiobasis.Mostothersettingsareconfigurablepervirtualstation.
Allvirtualstationsmustbeonthesamefrequency,butaslongastheprotocolsupportsthatfrequency,the
multipleprotocolscanbeusedconcurrently.Forinstance,iftheradioisconfiguredfora2.4Ghzchannel,the
stationscanbeb,g,orn.Iftheradioisona5Ghzchannel,thestationscanbeaorn.Thebandwidthcanbe
configuredforallprotocols.For802.11nand802.11AC,configuringtheMCSratesalsodeterminesthenumberof
spatialstreams(1x1,2x2,3x3,4x4etc).
TheVirtualStationsmaybeconfiguredwithallofthevirtualinterfacesonthesamesubnet,ordifferentsubnets,
dependingonthetestingrequirements.WhenusedwithsomethinglikeVoIP,itallowsalloftheVoIPcallstouse
thestandardIPports(withonecallpervirtualinterface).
TheCT520hasnomovingparts(otherthanthethreeremovableexternalantennaonswivelmounts)andwillfit
intoasmalltravelbagorbriefcaseforeasyportability.Itisalsocompletelysilent,soyoucanincludeitinyour
customerdemosandpresentations.Noadditionalhardwareorsoftwareisrequired,butitissuggestedthatyou
managethesystemusingtheLANforge-GUIonaseparatemachine.TheCT520canalsobemanagedoveraserial
consoleintextmodeorthroughadirectlyconnectedmonitor,mouseandkeyboard.

QuickStartGuide
1. ConnectManagementEthernetporttoManagementnetworkormanagementPC.Ifconnectingdirectly
toaPC,anEthernetcross-overcableshouldbeused.
2. Connecteth1wiredEthernetinterfacetowiredEthernetinterfaceontheAPornetworkundertest.This
usuallyisconsideredthe'server'sideofthenetwork.
3. TheClientsideofthenetworkwillbetheVirtualStationsconfiguredontheCT520WiFiNIC(s).
4. ConnectpowertostandardUSorEuropeanACpowersource.Ifusingexternalbatterypack,then
connecttothatinstead.
5. InstalltheLANforge-GUIonaseparatemanagementPCorLaptop.WindowsandLinuxGUIsare
supported:SelectthecorrectonefromtheCDROMorCandelaTechnologiesDownloadpageandinstall
it.TheCT520appliancehasawebserverthatalsoprovidestheLANforgeGUIs.
6. TheCT520shouldnowboot.IfDHCPisenabledontheManagementnetwork,theCT520will
automaticallyacquireanIPaddress.IfDHCPisnotavailable,theIPaddresswillbesetto
192.168.1.101bytheLANforgescripts.
7. StarttheLANforge-GUIonthemanagementPCandclickthe'Discover'button.ItshouldfindtheCT520
applianceandaddtheIPaddresstothedrop-downboxintheConnectwidget.Press'Connect'andyou

willbeconnectedtotheCT520.
8. SelectthePortMgrtabintheGUI.Double-clickonthedevicecalled'wiphy0'.ThisistheRadiodevice,
andshouldbeconfiguredforthecorrect,channel,country-code,etc.Next,selectoneormoreofthe
VirtualStationinterfacesandclick'Modify'.EnterthecorrectIPaddressinformation,SSIDand
WPA/WPA2password(ifEnabled).Afterapplyingthesechanges,theVirtualStationinterfaceshould
associatewiththeAPandbereadytosendtraffic.Youmaycreateupto32VirtualStationinterfacesper
CT520withthe'Create'button.
9. Oncetheinterfacesareconfiguredcorrectly,youcanclickontheLayer3,VOIP/RTPandother
LANforge-FIRErelatedGUItabsandconfigure/modify/start/stopparticulartrafficpatternsthatutilize
thevirtualstationsandwiredEthernetinterface.Inmostcases,youwillwantoneoftheFIREendpoints
tobeonthewiredinterfaceandtheothertobeontheWiFiVirtualStationinterface.Itisalsovalidto
generatetrafficbetweentwoVirtualStationinterfaces.TheGUIPluginsmenu(andright-clickonsome
tables)providessomepluginstodoautomatedtestingandreporting.Contactsupportifyouhave
suggestionsforimprovements.
10. AnyGUImodificationstakeplaceimmediatelyafteryouclick'Submit'.
