I am hoping to find an SDR that could not only detect IMSI but also providing signal strength information to figure out directions. I would really appreciate any advice on this.
We’re trying to capture cellphones on 3G and 4G/LTE networks and then perform radio location finding for each detected device.
I’m looking to perform a direction finding of a given smartphone with at least some degree of accuracy. Small places ~10m radius.
Has this been tested by Othernet for phones?
