CHAPTER1:INTRODUCTION
USBADAPTORINTRODUCTION
ThankyouforyourpurchaseoftheAIR802USB‐ADG‐2adaptor.ThisUSBadaptoroffersgreat
valuewhetheryouareanindividualpurchasingforuseathomeorforuseinabusinessofany
size.
USBadaptorsareasimpleandeasywaytoaddwirelesstoacomputer.Themajorityof
computersnowshipwithwirelesscardsbuilt‐in,butuserscommonlyfindweaksignals.This
weaksignalcanoccurduetoseveralfactors.Oneitmaybetoofarfromawirelessrouteror
accesspoint,mostinternalwirelesscardsdonotprovidesignificantradiofrequency(RF)gain.
Anotherfactoristhatalmostallbuilt‐incardshavetheantennasoperatinghorizontally,where
thewirelessrouteroraccesspointhasverticallypolarizedantennas.Thisresultsinsignificant
signalloss.Whatevertheresultingcauseoftheweaksignalis,theUSB‐ADG‐2withitsexternal
andremovableantennawillenhanceyourwirelessexperience.Thiskeytosuccessfulwireless
exerienceistheexternalandremovableantennawiththeflexibilityofusingalternative
antennas.
Thecompactdesignmakesiteasyforyoutotravelwiththeadaptor.Itdrawsitspowerfrom
theUSBport,soyoudonotneedanexternalpowersupply.
Thisadaptorsupportsveryhighspeedsupto54MbpspertheIEEE802.11gspecification.Of
course,mostbroadbandconnectionsareDSLorcablemodemsthatarelimitedgenerallytoless
than6Mbps,whichdeterminestheultimatethroughputratesinaccessingtheInternet.

CHAPTER2:NETWORKPLANNINGANDARCHITECTURE
AD‐HOCVERSUSINFRASTRUCTUREMODE
Wirelesslocalareanetworks(WLAN),asspecificedintheIEEE802.11b/gstandardshavetwo
differentconfigurationmodes:
•Ad‐Hoc
•Infrastructure

Ad‐HocisagroupofcomputersequippedwitheitherWLANcardsorwirelessUSBadapters.
ThegroupofcomputersiscalledaBasicServiceSet(BSS).Theycommunicatewitheachother
eliminatingtheneedforanaccesspointorrouterdevice.ComputersinAd‐Hocmodecannot
communicatewithcomputersonawirednetworkorconnecttotheInternet.Inour
configurationsoftwareitisreferredtoas,“APmode”.Howeverthisdoesnotimplythatitisan
accesspointinthenormalsense.Ad‐Hocisshowninthediagramontheleftsidebelow.




InfrastructureiswhereacomputerorothernetworkdeviceequippedwithwithWLANcardor
USBadaptercommunicatesdirectlywithanaccesspointorwirelessrouter.Infrastructure

USBEXTENSIONCABLE
TheremaybecircumstanceswhereyoumayprefernottoplugtheUSBadapterdirectlyintoa
USBport.Thismightincludescenariossuchasadesktopcomputersittingonthefloorandthe
desiretogettheadapteruphigherontopofadeskprovidinglesssignalobstructionsand
improvedperformance.AnUSBextensioncablewouldfacilitatethiseffort.Anotherscenario
mightbethatyouarenotusingtheantennashippedwiththeproductandhaveinstalleda
coaxialcablefromtheUSBadaptertoanantennainstalledoutdoorsforexternalnetwork
connectivity.Thecoaxialcable,dependingonthetypeandsizecouldcausesomestrainonthe
adapterinanUSBport.Inthiscase,theuseofaUSBextensioncablewouldbeuseful.

TherearetwotypesofUSBconnectors,TypeAandTypeB.TheTypeAisarectangular
connectorandTypeBisasquareconnector.TypeAisshowninthephotobelow.


IfyourapplicationrequiresusingtheUSBadapteroutsideoftheUSBportonyourcomputer,
thenanUSBextensioncableisappropriate.YouwillneedaUSBTypeA(male)toplugintothe
computerandaUSBTypeA(female)toplugintheUSBadapter.USBextensioncablesby
standardsspecificationarelimitedto15feetinlength.AIR802currentlymanufacturesUSB
extenssioncablesin3and6footUSBlengthsandtheyareavailableat

ALTERNATIVEANTENNAS
TheUSB‐ADG‐2issoldwitha5dBigaindipoletypeantena.Thisantennaradiatesradio
frequency(RF)in360degrees.Usersmaydependingontheirapplicationandneedsfind
alternativeantennastobeuseful.AIR802manufacturesawiderangeofantennaswhichcould
beusedwiththisadapter.Antennasalonedonotdeterminethedistancethatyoumayreach.It
isafactoroftheRFtransmitpowerandreceiversensitivity(withtheUSBadapterandthe
accesspoint/routerdevice),anycablingloss,freespacelossandantennagainandotherfactors
suchasinterferenceinthe2.4GHzISMband.Withline‐of‐sight,antennnasandaproper
installation,apoint‐to‐pointnetworkcanbeachievedfor1mileormore.

Outdoorantennascanbeusedindoorsandwillalmostalwayswillprovidebetterresultsthan
anindoorantennaofthesamegain.ToinstallanantennaremoteoftheUSBadapter,youwill
needtopurchaseaspecialAIR802antennacableasssembly.Thecableassemblywillrequirea
RP‐SMA(plug)attheUSBadapterend.AIR802outdoorantennaswillrequireaN(male)

APPLICATIONS

ResidentialNetwork–ComputertoRouterConnectivity
•Residentialuserscommonlydonotreceiveadequatesignalcoveragethrougouttheir
home.Itisoftenassumedthatreplacingtheexistingrouterantennaforamodelwith
highergainwillresolvetheissue.Whileinsomecircumstancesthismayhelp,often
theproblemisthattheinternalwirelesscardinthecomputerproducestoweakofa
signaltoreachtherouter.InstallingtheAIR802USB‐ADG‐2devicewillnormally
significantlyimprovethisscenario.Externalantennassimplyprovidebetter
performance.
