◆ ChannelBandwidth —TheAP optionsforchannelbandwidthinclude5,10, 
20,40and80MHz.Using20MHzgivesan802.11gconnectionaspeedof 
54Mbps andan802.11nconne ctionaspeedofupto108Mbps,andensures

backwardcomplianceforslower802.11bdevices.Settingthechannel  bandwidth
to40MHzprovidesaconnectionspeedfor802.11nofup to300 Mbps.Usinga
channelbandwidthof80MHzprovidesaconnectionspeedupto
866.7Mbps.(Default:20MHz;Range:5MHz,10MHz, 20MHz,40MHz,80MHz)

◆ Channel—Theradiochannelthattheaccesspointusestocommunicatewith 
wirelessclients.Whenmultipleaccesspointsaredeployedinthesamearea,set 
thechannelonneighbori ngaccesspointsatleastfivechannelsaparttoavoid 
interferencewitheachother.Forexample,for11g/n20MHzmodeyoucan 
deployup tothreeaccesspointsinthesameareausingchannels1,6,11.Note
thatwirelessclientsautomaticallysetthechanneltothesameasthatusedby

theaccesspointtowhichitislinked.(Theavailablechannelsaredependenton 
the802.11Mode,ChannelBandwidth,andCountryCodesettings.)
