Operators do not benefit much from installing sites in rural/remote areas with low user density. They are always looking for maximizing their revenue in any possible way to make it worthwhile.
So they usually insist on wide open Electrical tilts with maximum RS power.
But it does not necessarily bring in the expected results.
Also, in many cases, engineers overshrink the coverage of a cell through extreme tilting to improve service quality but again to no avail.
A common myth about antenna tilt is that LESS gives better coverage, MORE gives better throughput.
I tend to disagree with that.
For highest revenue/performance, our main objective should be to direct the strongest beam of the cell to the most dense/interesting point in the area.
Putting an antenna on a 50 m tower on a 3000 m high mountain with minimum tilt will only serve flying birds.
Excessive downtilt without attention to the point of interest will only hit barren fields and rocks.
We are transferring energy and we should not waste it. Treat the antenna just like a lamp. Focus the beam where it is needed. Don’t just disperse it blindly.
Even without advanced tools like Atoll, it is quite straightforward to calculate the required tilt for directing the beam at the region of interest.
