Similar to the GSM Field Test Mode & Phonecall video, this video demonstrates how to place a smartphone into field test mode to find the UMTS uplink frequency it has been allocated. Tuning an RTL-SDR and a professional spectrum analyzer to this frequency, we are able to see what happens when we stream a video to the device.
We invite you to view more at http://www.desktopSDR.com, where you are able to download a free copy of the book and its support files.
