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)
✓ Gateway node ID tracked
✓ Reduced position precision: ~1500.0m accuracy

Exposure Risks:

⚠ Visible to all nodes on channel
⚠ Default channel - no encryption
⚠ Packet visible to MQTT subscribers
⚠ Multi-hop path visible (5 hops)
⚠ RF signal metrics exposed (location inference possible)

MQTT-Specific Fields

Gateway ID:	`!db2b2610`
Position Precision:	14 bits (~1500.0m accuracy)
Position precision meters:	`1500.0`
Signal Metrics:	RSSI: -87.0 dBm SNR: 6.25 dB
