Ers,

Absolutely. If you are certain that the frequencies are clean ( = no interference) and that the coverage area cannot be enhanced (with high power transmitters, or better antennas, or thicker feeders, or TMA, or remove some combiners, etc)

Keep in mind that what you need is to increase the coverage.. There is no miracle :
– increase current cell coverage (see above)
– or, add a repeater
– or, add a BTS

Now, there is a trick. It’s not “good” IMO, but it will make your stats look better. By changing some parameters, you can actually forbid the user with poor RXLEV to establish a call.
Less “low rxlev” calls = less call drops
… but also = less traffic.

the 2 parameters you can use are :
RACH TA FILTER
RXLEV ACCESS MIN

But really, if anyone asks you who told you to do that, don’t mention me. The point of my job is to increase traffic, because traffic= revenues !

Just say it’s an idea from..
