RF / SDR Security Research

ACTION REQUIRED (execute immediately after reading)

1. NOW: Spectrum and transmission are strictly regulated by law; only authorized frequency bands/shielded rooms/experimental targets
2. NOW: scope specifies the device, frequency band, and whether transmission is allowed (receive-only by default)
3. ACT: receive-only identification → demodulation analysis → laboratory reproduction and evaluation

Applicable scenarios

• Non-Wi-Fi RF such as wireless remote controls/sensors (authorized)
• Protocol research such as ADS-B/remote control (lawful reception)
• Division of labor with wifi-wireless: this skill focuses on general-purpose SDR RF; Wi-Fi attack and defense goes through R29

Workflow

□ 法规与许可确认
□ 只收：识别中心频率与调制
□ GNU Radio / URH 分析
□ 重放仅屏蔽室且书面允许
□ 结论侧重：是否可未授权控制 / 加固建议

Toolchain

Tool	Purpose
RTL-SDR / HackRF (compliant)	Transceiver hardware
URH / GNU Radio	Analysis
Inspectrum	Signal

Routing context

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

Task completion self-check

• Is it receive-only by default and are regulatory boundaries documented?
• Checklist？
