3G Signal Strength Indicator on Linux

Have not been able to find any signal strength indicator for 3G devices on Linux. So unable to measure the signal strength. However the 'at+csq' command can be used to find the signal strength. It returns a number between 0 and 31 (0 being minimum and 31 being the maximum strength).
The problem was how to convert it to power measurements (dB). Fortunately I found a solution to convert the numbers to dB measurements at .

Planning to write a script for displaying the signal strength in python.

Hey there. Did you ever write a Python script for this? Thanks

I tried finding a way to get some documents from Qualcomm, but could never get any. Hence never got to writing one. In the meantime I stopped using 3G and moved on to fibre.
