Hey.
Did I got it right that instead of using at commands and gprs-capable modem for clock
calibration (as in http://gnuradio.org/redmine/wiki/1/OpenBTSClockCalibration) we can
use output of [power] section of cell_log?
Have somebody tried this?
Above-mentioned page says that it "is obvious how the values were obtained" for
executing ./kal script. As a matter of fact - it's not, at least not for newbies :(
For example I got following in cell_log:
arfcn 740 -99 -105 -109 -108 -110 -107 -108 -103 -109 -108 -110 -100
Seems like pretty good signal strength.
No I should run ./kal -f NNN -u
adjust clock in my usrp and run ./kal again.
But what's the formula for obtaining NNN from arfcn 740?
Can you advise me on some improving reading?
thank you,
Max.
