I have a question about downtilt based only on TA counters without drivetest data.
Here is an example of how difficult it is to decide on downtilt even with drive test data.
PCI in black is not dominant outside the area circled in red yet is degrading RSRQ and SINR in lot of other places due to strong RSRP outside it’s serving area. Can we donwtilt further this PCI in black?
One would answer that we must do this. In reality we need to check: who else will be dominant in the area circled in red after PCI in black will be dominant.
Next question: where else we will lose coverage of PCI in black if we downtilt this PCI in black? This drivetest is nit exhaustive and another one needs to be done to understand teh whole footprint of the PCI in black not just the one in this limited drivetest.
Bottom line is that downtilting withoutdrivetest data and rearanging uptilts andf azimuths of other sectors is a bad idea.
