DTIM(DeliveryTrafficIndication
Map)
ThisistheDeliveryTrafficIndicationMap.Itisusedtoalerttheclientsthat
multicastandbroadcastpacketsbufferedattheAPwillbetransmitted
immediatelyafterthetransmissionofthisbeaconframe.Youcanchange
thevaluefrom1to255.TheAP
willcheckthebuffereddataaccordingto
thisvalue.Forexample,selecting“1”meanstocheckthebuffereddataat
everybeacon.
FragmentSize Alargedataframeisfragmentedintoseveralfragmentseachofsizeequal
tofragmentthreshold.Bytuningthefragmentthresholdvalue,wecanget
varyingfragmentsizes.
ShortGI(GuardInterval) AGIisaperiodoftimebetweensymboltransmissionthatallows
reflections(frommultipath)fromthepreviousdatatransmissiontosettle
beforetransmittinganewsymbol.The802.11ndraftspecifiestwoguard
intervals:400ns(short)and800ns(long).Supportofthe400nsGIis
optionalfor
transmitandreceive.Thepurposeofaguardintervalisto
introduceimmunitytopropagationdelays,echoes,andreflectionsto
whichdigitaldataisnormallyverysensitive.
Aggregation Apartofthe802.11nstandardthatallowssendingmultipleframesper
singleaccesstothemediumbycombiningframestogetherintoonelarger
frame.Itcreatesthelargerframebycombiningsmallerframeswiththe
samephysicalsource,destinationendpoints,andtrafficclass(QoS)into
onelargeframe
withacommonMACheader
