Hi, List!
I'm new to OpenBSC, and I'm experimenting some configuration of the
program.
Now I have to try to change the power of the BaseStation, so that I can
set how far mobile phones can catch the signal of my BaseStation.
I thought, I can change the values of "ms max power" or "nominal
power", but I don't see any difference.
Is it possible to do what I try? If yes, how?
Thanks for any help!

Hello Luca,
in the config file, set "max_power_red 0'
This means the amount to reduce the power is 0 (which means it's the max
power). So if you want to attenuate the power, you have to raise the
value e.g. 12.
By the way, I assume you're using nanobts.
Greetings,
Nordin.

Hi, Nordin!
Thanks for your answer.
I read the documentation again, and I have another question. Does the
value of max_power_red works together with "nominal power"?
I tried to set "nominal power" to 100 and max_power_red to 0, and then
to increase max_power_red.
I don't see any difference if I search the net with my phone...
What am I doing wrong?
Thanks

According to OpenBSC wiki:
"How many dBm is the nominal power of this BTS. This setting is only
used as a base for computing power levels displayed to the user. "
So this one is just to calculate the powervalue to be displayed for you,
so I assume it does nothing more than that.
But how do you test by the way?

It's difficult to explain, but I just want to restrict (or enlarge) the
field in which is my BaseStation to find.
Is it possible?

I believe he wants to limit the range of his bts by decreasing the downlink power.

As far as I understand, he means that he wants to control BTS cover area.

Ok, but to my knowledge the only way to do that is by modifying the
"max_power_red" in the config file or through VTY terminal.
You should use a dummy load with your BTS, this limits the range within
a meter, so you don't get trouble with the government ;-)
Or use farada's cage or something...

The only two ways to control a cells coverage area is to set the subscriber max distance
attribute or reduce the BTS / MS TX power.

Sorry for the short reply, I'm on my mobile. There are two elements
that govern how far your network will work. In a standard deployment
of a nanoBTS, this will always be the EIRP of the BTS.
On a macro network it's usually down to the subscribers maximum EIRP
(30dBM at GSM 1800). There's various other factors such as receive
diversity (both polarity and spatial which I won't discuss here).
The setting you need to change is the max power reduction of each TRX.
By setting this to 0, you will be TXing at 23dBm (200mw) on an 1800
nanoBTS.
