Reducing Tilt vs Reducing Power

Dear Experts.

What is the impact of reducing tilt vs reducing power?

Reducing tilt will increase indoor penetration but will reduce cell coverage at the edge.

Reducing power will just reduce cell coverage at the edge.


Power reduction will impact SINR as compared to Tilt reduction?

Yes, power reduction will decrease SINR in all cell.
Downtilt will increase SINR for indoor but will decrease SINR for cell edge.

Ok, so when do we prefer power reduction and tilt reduction?

Power and electrical tilt is best rather a mechanical tilt due to elec is for more reduce the interference with same site built for coverage.
