Tools: Wireshark, QXDM, Qualcomm APEX, Anritsu MT8000A

Protocol Analysis Tools

Wireshark is the universal protocol analyzer for IP-layer and SIP/HTTP2 message decoding, essential for analyzing 5GC SBI interfaces. QXDM (Qualcomm eXtensible Diagnostic Monitor) captures chipset-level protocol logs from Qualcomm-based UEs, providing visibility into internal RRC, NAS, and PHY layer processing that is invisible on the air interface. Qualcomm APEX (Automated Protocol EXerciser) is a test automation platform that scripts complex multi-step protocol procedures for regression testing. These tools together provide full-stack visibility from application to physical layer.
