Realcase2:Oscillationcausedbysignalreflection
Basicinformationdescription
1. Theoutdoorantennaisrightfacingthe
celltower;
2. Thereisabigbuildinginfrontofthe
outdoorantenna,about100ftawayfrom
theoutdoorantenna;
3. Distancebetweentheindoorand
outdoorantennaisgoodenough;
4. Indicatorsforband12andband13on
thepanelalwayssolidgreenafterpower
on.Otherbandindicatorsflash.
Caseanalysis:
Theoutersurfaceofthebuildingfacingthe
outdoorantenna,becomeabigreflect
surface.Itreflectthesignalfromtheoutdoor
antennatotheindoorantenna.
Solution:
Verticalrotatingoutdoorantennaup15to30degree.Keepthecelltoweratthe
bottomedgeofthemainbeam,sametimemovepartoftheoppositebuildingoutof
themainbeam.Thisreducestheenergyofthereflectedsignal.
