Wirelessoverview

TheSonicPointN2ispartofthenextevolutionarygenerationinwirelessaccesspointsaftertheSonicWallSonicPointNandNDR.

TheSonicPointN2providesphysicallayerenhancementsforhigherthroughputwithamaximumdatarateof450Mbps.Toachieve

this,theSonicPointN2uses:

•Moreantennas—threeantennasforthe5GHzradio,andthreemoreforthe2.4GHzradio

•Widerchannels—40MHz‐widechannelsforthe802.11nradiomodule

•Morespatialstreams—3X3multiple‐inputandmultiple‐output,(MIMO)forthe802.11nradiomodule,wherethecapacity

ofaradiolinkismultipliedusingmultipathpropagation.

SonicWallwirelessfirewalling

WhenawirelessdeviceusesaSonicWallSonicPointN2

wirelessaccesspointtocommunicatewithawirelessdevice

onanothersubnetoronacompletelydifferentnetwork,traffic

betweenthedevicesisforcedtotraversetheSonicWall

networksecurityappliance.Thistraversalenablessecurity

servicestobeenforcedbySonicOS.

Standardpracticeforwirelessfirewalling(whereonewireless

clientiscommunicatingwithanother)bypassesmanyofthe

criticalsecurityservices.Thefollowingillustrationshowsthe

standardpracticeforwirelessfirewalling.

Standardwirelessfirewalling

Manysecurityproductsonthemarketsharethispotential

vulnerabilitywhentwousersconnectedbyacommonhubor

wirelessaccesspointwishtoexchangedata.

SonicWalladdressesthissecurityshortcomingbymanaging

theSonicPointaccesspointsfromthenetworksecurity

appliance.Thisallowscompletecontrolofthewirelessspace,

includingzoneenforcementofsecurityservicesandcomplete

Frequencybandsandchannels

Therearecurrentlyfivewidelyadoptedstandardsfor802.11wirelessnetworktypes:a,b,g,n,andac.802.11nand802.11acare

thenewestandhighestcapacitystandards,butolderclientdevicesmaynotbeabletoutilizethenewerstandards.

Differentfrequencybandsprovidevaryingsignalstrengthandqualityoverdifferentdistanceranges.Signalsinthe2.4GHzrange

tendtopassthroughphysicalbarriersbetterandcarryfartherthanthoseinthe5GHzrange,buttheydonotprovideashigha

datarate.Signalsinthe5GHzrangeprovidefasterdataratesforbetterthroughput,butthesignalattenuatesfasterandisbest

RefertoRadiofrequencybarriersandRFinterferenceonpage16fordetailedinformationaboutRFbarriersandinterference.

Toallowmultipleseparatewirelessnetworksinasharedandconfinedspace,theRFmediumisdividedintochannels.Fordevices

inthe5GHzrange(802.11a/n/ac),thismeansthepossibilityofupto23discretechannels.

Fordevicesusingthe2.4GHzrange(802.11b/g/n),thewirelessspaceislimitedtoamaximumof14overlappingchannels.Asa

resultoftheseoverlappingchannels,2.4GHztechnologyprovidesonlyatotalofthreediscretechannels.
