Dear Friends,
I'm in a big problem, I must perform a CW
"continues wave' drive test for UMTS model tuning
project for 40 sites and I must start in two days.
I know how to perform 2G (GSM) drive test but
the CW drive test is a new for me.
So, please
please could you describe the drive test process
for the CW in steps, I will use W-CDMA Area Tester
for this drive test.
Please,
it's not only important but it's a very urgent.
I'm sure you could help me.
Waiting
your reply ASAP.

It sounds to me like you need to radiate an unmodulated
carrier from each BTS, and with a spectrum or transmission
analyzer and GPS linked to a laptop, drive out radially
recording the CW carrier level. Suitable software
then translates the data into a map overlay to produce
carrier level contours for each BTS.
I guess
this has to be done for each carrier, but the test
spec should state this.
