Thisisusefulifyouareusingalaptoporotherdevicewithasmallscreen.
ThevaluesinFigure 10‐5areasexpected:TheHBSisusingalittleoverhalfitscapacityinthe
uplinkdirection.Theex cessisoverheadrequiredtomonitorthesector.Inthedownlink
direction,theexcessover50%isincidentalaswillbeseenfromthetoprightgraphshowing
sectorutilizationasatimeline:

The“glitches”areduetoJperfandhostcomputerlimitations.
Thelowerpairofgraphsshowutilizat ionofaselectedHSU
eithersectorrelativeorself‐
relative.UsetheselectorintheHSUutilizationtitlebartomakeachoice.
WefirstlookattheHSUbasedutilization.(Inourview,theSectorrelativemeasurementswill
makemoresenseifwefirstunderstandwhatishappeningattheHSUlevel.)
Figure 10‐7shows
theHSUrelativeutilizationfortheselectedHSU.Thegreenpercentage
barsareeas ytounderstand.Theyarebothwellover100%sincethewholesectorisgrossly
under‐allocated.Bothvaluesareover1000%!Morespecifically,iftheHSUcouldonlyuseits
twoallocatedtimeslotsinboth
directions,itisfairlyeasytodemonstratethatitwouldnotbe
abletooperateatmaximumcapacity.Sinceitisableto“borrow”theunuseduplinkand
downlinktimeslots,itreachesmaximumthroughputandoperatesatovertentimesthe
assuredratedefinebytwotimeslotsinbothdirections.
