Capture raw 2G/3G/4G radio frames from Qualcomm-based phones and modems.

A diagnostic-port client for Qualcomm devices that turns them into a passive 2G/3G/4G radio sniffer with PCAP output.

QCSuper communicates with Qualcomm-based phones and modems over their diagnostic interface to capture raw 2G, 3G, and 4G radio frames. It produces PCAP output suitable for analysis in Wireshark and similar tools.

What it does

• Speaks to the Qualcomm DIAG protocol on rooted Android devices and supported USB modems.
• Captures raw radio frames across GSM, UMTS, and LTE.
• Writes PCAP files (and a live PCAP stream) using the GSMTAP encapsulation Wireshark already understands.
• Supports several capture modes including the Qualcomm DIAG monitor and live-monitor outputs.

Best for

• Radio-side researchers studying real-world 2G/3G/4G traffic.
• Trainers running RAN security and IMSI-catcher lab exercises.
• Analysts correlating handset-side captures with core-network traces.
