Help on finding the features for cell phone companies

GNU Radio

Hi All,

I am using USRP to sweep the whole cell phone band and pick up the cell
phone signals by spectrum analysis. How about, if I want to separate the
signals by different companies? Does anyone have suggestions on how to
do
it? How can I find the feature in frequency domain for at&t, verizon, or
t-mobile, etc?

Thanks,
Brook

The FCC has a search page where you can specify the state you’re in
and a frequency range, and it will tell you all the licensed people
for that spectrum:

Hope this helps.
