Thank you pix. Your answer helped. Also, I found this on Ascom’s website:
“It is possible to measure C/I in both idle and dedicated mode. In idle mode, you will get a C/I value on the BCCH carrier in the serving cell.”
So, my initial assumption that C/I in GSM is only measured for dedicated mode was wrong (although that is what I deduced from observing TEMS logs).
I am throwing whatever I got at you guys so that I may stand corrected at the end. This is a great forum.
