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: MediumFast
  • ✓ Gateway node ID tracked
  • ✓ Reduced position precision: ~1500.0m accuracy
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (2 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !909ec2ec
Position Precision: 14 bits (~1500.0m accuracy)
Position precision meters: 1500.0
Signal Metrics: RSSI: -40.0 dBm
SNR: 11.00 dB
