in the openbsc.cfg i find a parameter "ms max
power" which is set to
15 dBm (apporox 30mW) by default.
http://openbsc.osmocom.org/trac/wiki/osmo-nitb_VTY says the
following: "maximum transmit power (in dBm) to be used by MS in this
BTS. This is used in the System Information on the BCCH as well as
for the MS power level at the time a dedicated channel is
activated."
My question is how low may i set ms max power level? Is 15dBm
already the lowest possible minimum or can i set it down to 1dBm if
i like?
I just looked it up.
GSM 05.05 speaks of values 0..39dBm, although the underlying thing is
the 'Power control level', MS_TXPWR_MAX_CCH, which has a range of 0..31.
This is also mentioned in GSM 05.08. I also found [1].
