RF / SDR Security Research

ACTION REQUIRED (execute immediately after reading)

1. NOW: spectrum and transmission are strictly regulated by law; authorized bands/shielded rooms/lab targets only
2. NOW: scope states devices, frequency bands, whether transmission is allowed (receive-only by default)
3. ACT: receive-only identification → demodulation analysis → lab reproduction assessment

Applicable Scenarios

• Non-Wi-Fi RF such as wireless remotes/sensors (authorized)
• ADS-B/remote-control and similar protocol research (legal reception)
• Division of labor with wifi-wireless: this skill leans toward general-purpose SDR RF; Wi-Fi offense/defense goes to R29

Workflow

□ Regulatory and licensing confirmation
□ Receive only: identify center frequency and modulation
□ Analyze with GNU Radio / URH
□ Replay only in a shielded room and with written permission
□ Conclusions focus on: whether unauthorized control is possible / hardening recommendations

Routing Context

Upstream: MASTER R38
MUST NOT: interfering with public communications, unauthorized transmission

Task Completion Self-Check

• Receive-only by default with regulatory boundaries recorded?
• Checklist?
