gsmtap

Educational passive GSM analyser: decodes GSMTAP from gr-gsm and RTL-SDR into cells, paging, identities and signalling sessions

Clean-room Qualcomm /dev/diag capture daemon with live IMSI-catcher detection heuristics and RRC/NAS decode. MIT.

Live LTE/5G NAS & RRC from rooted Shannon-modem Pixels (adb → SCAT → GSMTAP → Wireshark), with measurement-report and handover analysis.

Geo-targeted emergency evacuation over Cell Broadcast, in Go. Decides who is warned and which exit they take, then transmits on the matching cell where simulated handsets decode it off the air.

Idiomatic Rust implementation of selected libosmocore functionality, modeled on recorded C behavior for compatibility

Rust GSMTAP parser and encoder, a web workbench for live GSMTAP traffic, and libosmocore reference harnesses that record C behavior
