Hacking the Wireless World with Software Defined Radio - 2.0
summary
Live demos use GNU Radio and USRPs (B200/B210/x310/e310) to capture up to 56 MHz of spectrum, run an OpenBTS 2G base station from a USB-powered board, and pull real GSM control bursts and a 20 dB signal lift from a drone at ~25 m altitude. A QPSK video link off the drone works; a keyless‑entry LF→UHF relay prototype fails due to latency. Backscatter toll tags and restaurant pagers are decoded and replayed, and ISEE‑3’s 2 GHz transponder is contacted after recreating vintage modems.
