wireless network

Classification

Wirelessnetworkisageneraltermforatypeofdatatransmissionnetworkusingradiotechnology.Accordingtodifferentnetworkcoverage,differentnetworkapplicationscenarios,anddifferentnetworkarchitectures,wirelessnetworkscanbedividedintodifferentcategories.Inthefollowing,theclassificationofwirelessnetworkswillbeexplainedindetailfromtheabovethreeperspectives.

Accordingtothedifferentnetworkcoverage,wirelessnetworkscanbedividedintowirelesswideareanetworks(WWAN:WirelessWideAreaNetwork),wirelesslocalareanetworks(WLAN:WirelessLocalAreaNetwork),andwirelessmetropolitanareanetworks(WMAN:WirelessMetropolitanAreaNetwork)andWirelessPersonalAreaNetwork(WPAN:WirelessPersonalAreaNetwork).WirelessWANisbasedonmobilecommunicationinfrastructureandisoperatedbynetworkoperators,suchasChinaMobile,ChinaUnicom,Softbankandotheroperators,whoareresponsibleforcommunicationservicesinallareasofacityorevenallareasofacountry.Awirelesslocalareanetworkisanetworkresponsibleforwirelesscommunicationaccesswithinashortdistance,anditsnetworkconnectioncapabilityisverypowerful.Atpresent,thewirelesslocalareanetworkisbasedontheIEEE802.11technicalstandardoftheIEEEacademicorganization,whichisalsotheso-calledWIFInetwork.WirelessWANandwirelesslocalareanetworkarenotcompletelyindependentofeachother.Theycanbecombinedtoprovidemorepowerfulwirelessnetworkservices.Wirelesslocalareanetworkallowsaccessuserstoshareinformationwithinthelocalarea,andwirelessWANallowsaccessusersShareinformationoutsidethelocalarea.Awirelessmetropolitanareanetworkisawirelessnetworkthatallowsaccessuserstoaccessfixedlocations,anditconnectsmultiplefixedlocationsinacityorregion.Awirelesspersonalareanetworkisawirelessnetworkinwhichuserspersonallyconnecttheirownportabledevicesthroughcommunicationdevicesforshort-distancewirelessconnection.

Accordingtodifferentnetworkapplications,wirelessnetworkscanbedividedintowirelesssensornetworks(WSN.WirelessSensorNetwork),wirelessMeshnetworks,alsoknownasmulti-hopnetworks(Multi-hopNetwork),wearableWirelessnetworkandwirelessbodyareanetwork(WBAN:WirelessBodyAreaNetwork),etc.

Accordingtodifferentwirelessnetworktopologies,wirelessnetworkscanbedividedintodifferenttypes.Asweallknow,inwirednetworks,therearefivemajornetworktopologies,namelyBus,Ring,Star,TreeandMesh.However,unlikewirednetworks,inwirelessnetworks,thereareonlytwotopologies:starandmesh.Inthestararchitecture,acentralcomputerismainlyresponsibleforthecommunicationbetweentheclients,andthecommunicationbetweeneverytwoclientsmustpassthroughthiscentralcomputer.Themeshtopologyarchitectureisdifferentfromthestararchitecture.Itdoesnothaveacentralcomputerresponsibleforcommunicationbetweenclients,buteachclientcommunicatesdirectlywiththeclientswithinitscommunicationrange.

Features

1.Strongmobility,abletobreakthroughthelimitationsoftimeandspace.

Wirelessnetworkstransmitnetworksignalsbytransmittingradiowaves.Aslongastheyarewithinthetransmittingrange,peoplecanusethecorrespondingreceivingequipmenttoconnecttothecorrespondingnetwork.Thisgreatlygetsridoftheconstraintsofspaceandtime,whichcannotbeachievedbytraditionalnetworks.

2.Thenetworkexpansionperformanceisrelativelystrong.

Differentfromwirednetworks,wirelessnetworksbreakthroughthelimitationsofwirednetworks.Theycanaccesspeoplethroughwirelesssignalsatanytime,andtheirnetworkexpansionperformanceisrelativelystrong,whichcaneffectivelyachievenetworkexpansionandConfigurationsettings,etc.Userswillalsobecomemoreefficientandconvenientwhenaccessinginformation.Thewirelessnetworknotonlyexpandspeople'sspaceforusingthenetwork,butalsoimprovestheefficiencyofthenetwork.

3.Theequipmentiseasytoinstallandlowincost.

Generallyspeaking,theprocessofinstallingawirednetworkismorecomplicatedandcumbersome.Inadditiontoalargenumberofnetworkcablesandnetworkcableconnectors,thewirednetworkrequiresaveryhighmaintenancecost.Thewirelessnetworkdoesnotneedtolayalargenumberofnetworkcables,justinstallawirelessnetworktransmissiondevice.Atthesametime,thisalsocreatesveryconvenientconditionsforlaternetworkmaintenance,whichgreatlyreducesthecostofearlynetworkinstallationandlatermaintenance.

Comparedwiththewirednetwork,themainfeatureofthewirelessnetworkisthatitcompletelyeliminatesthelimitationsofthewirednetwork,realizesthewirelesstransmissionofinformation,andenablespeopletousethenetworkmorefreely.Atthesametime,networkoperatorsarealsoveryconvenienttooperate.Firstofall,lineconstructioncostsarereduced,runningtimeisshortened,andcostreturnsandprofitproductionarerelativelyfast.Theseadvantagesincludeimprovedwirelessinformationtransmissionmanagementforadministratorsandgreaterflexibilityforuserswhodonothavespaceconstraintsonthenetwork.
