DTIM 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.
