8.4.2MoreontheThresholds
RSLThresholds
TwoRSLThresholdscanbedefined.Theyareusedasanindicatorofproblemsintheradio
channel.YoucanchecktheRSSfromtheLinkBudgetCalculatorresultsduringinstallation.
Valuesof‐5dBand‐8dBfromthecurrentRSSaretypical.
TSLThreshold
Acounterismaintained,ofthenumberofsecondintervalsduringwhichTxpowerexceeds
thisthreshold.
BBERThreshold
TheBackgroundBlockErrorRatioismeasuredasa percentage .Thethresholdcanbesetfrom
0.1%upto50%.
An8%thresholdisrecommended.Iftherearenoproblemsduringtheinterval,thenforthat
threshold,therecommendedBBERvalueshouldbe0.Sincethesystemprovidesalossless
Ethernetservice,thereisthroughputdegradationincaseofinterference.Thedegradationis
proportionaltotheBBER.
