MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Broadcast

Privacy Features:

✓ Direct LoRa transmission (not via MQTT)
✓ Custom channel: MediumSlow
✓ Gateway node ID tracked
✓ Zero-hop: direct from source to MQTT gateway

Exposure Risks:

⚠ Visible to all nodes on channel
⚠ Packet visible to MQTT subscribers
⚠ Full GPS precision shared
⚠ RF signal metrics exposed (location inference possible)

MQTT-Specific Fields

Gateway ID:	`!9eed0854`
Position Precision:	32 bits (~1.0m accuracy)
Position precision meters:	`1.0`
Zero Hop Policy:	Enabled Direct gateway connection
Signal Metrics:	RSSI: -119.0 dBm SNR: -10.50 dB
