Captures raw 2G/3G/4G (and, on some modems, 5G) radio frames from Qualcomm-based phones and modems via the /dev/diag DIAG interface, wraps them in GSMTAP and streams a live PCAP into Wireshark. Turns a cheap Qualcomm modem such as the SIM7600 into a passive cellular-signalling sniffer, an alternative to an SDR cell-search receiver.
