4.Changetheindoorantennatypetoanantennawithamoredirectionalantennapattern.
Orienttheindoorantennaandoutdoorantenna sotheypointinoppositedirections.
5.Reducethebooster’sdownlink gainviasettingthegainparameterinapp.Keeptheuplink
gainvalueanddownlinkgainvaluethe
samethenrestartthebooster.
Note:Uplinkgainmustbeequaltoornotlessthan5dBbelowthedownlinkgain,toavoid
interferencewiththelocalcarrier'scellsitenetwork.
Target:TheAlarmissuesaresolvedwhenthereisnoAlarmwarningfromtheapp.
EliminateALCwarningproblems:
1.Adjusttheantennas’directionsorlocationstolowerdownlinkreceivedsignallevel.
2.Slowlyreducethedownlinkgainviasettingthegainparameterinapp.
3.Iftheabovemethodsdon’twork,reducethebooster’sgainwithanexternalattenuatorin
linewiththeoutdoorantennaorrepla cewithlower
gainantenna.
Target:TheoverloadissuesarefixedwhenthereisnoALCwarningfromtheapp.Please
notethatalowgainmayresultinsmallercoveragearea.Thiscanbeimprovedbyadjusting
theoutdoorantennatoreceiveastrongersignal.Eliminatepoorcoverageproblemswhen

¢Theweakdownlinksignalleadstothelowoutputsignallevel.Changethedirectionor
positionoftheoutdoorantenna.Youmayalsotryreplacingtheoutdoorantennawitha
highergainantennatoincreasetheincoming
signal.
*Checktoseeifitisnecessarytoaddmoreindoorantennas.Barrierssuchaswallscanblock
thesignalindoors.Youshouldalsochecktheboostertomakesurethepowerismaximized.
Tryinstallingmoreindoorantennasorreplacetheboosterwithahigherpoweredone.
2.
Ifthesignalinasmallse ctionofthebuildinghasn'tbeenimproved,trythefollowing:
*Checktoseeiftheindoorantennaisi nstalledcorrectly.Trymovingtheantennatoimprove
coverage.
Tryadjustingthedirectiontheindoorantennaispointing
.
Checkwhetheritisnecessarytoaddoneormoreantennastoenhancethecoverageof

By capturing the best input signal you will be able to enjoy the maximumcoverage
andbestqualitysignalinsidewhereyourIndoorantennasarelocated.Thebetterthe
inputsignal, the bettertheoutputsignal. In order to findthe bestinput signal,you
want to place your outdoor antenna as high as possible with the leas t amount of
obstructionbetween the antennaand thecellular base tower. A clearline  ofsite is
ideal.
Isolatingthesignalfromtheantennasisdonebyensuringthattheantennasarenot
