Cross-Protocol Failure Patterns

The same root causes repeat across Wi-Fi, BLE, RFID/NFC, Sub-GHz, IR, and SDR. Use this taxonomy before protocol-specific debugging.

Failure taxonomy by root cause

• Environment: interference, poor positioning, unstable power.
• Configuration: wrong channel/band/profile/permissions.
• Assumption: expecting insecure behavior on modern secure systems.
• Instrumentation: weak logging, stale cache, insufficient baselines.

Myth vs reality

Myth: “New tool = fixed results.”
Reality: Process quality beats tool upgrades in most failure cases.

Validation criteria

1. You can reproduce failure and success on demand.
2. Only one variable changes per iteration.
3. Evidence artifacts (logs/captures) align with conclusions.
