TheMaximumThroughputModeisirrelevanthereandshouldbeleftasis.TheSharing
Percentage,(between15‐75%,default50%)isthemaximumcapacitytheHBSispreparedto
relinquishinfavourofothertransmitter sonthisband.(Theremaybeseveral.)TheMinimal
Contentionslotlength(5‐20ms,default10ms)istheamountoftimetheHBSispreparedto

Basicallytheideaisthis:SupposethattheHBSissettoSharingPercentageofsay20%and
MinimumContentionSlotlengthof10msasshown.Itsays,“Iampreparedtobepoliteand
relinquishupto20%ofmycapacitybutIwillbuttinandtransmitaburstfrom10msafter
inte rferencedetection.”
Theremainingtabsworkasexpected.
