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: ~2900.0m accuracy
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Default channel - no encryption
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ Multi-hop path visible (1 hops)
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !a2e1a910
Position Precision: 13 bits (~2900.0m accuracy)
Position precision meters: 2900.0
Signal Metrics: RSSI: -114.0 dBm
SNR: -15.00 dB
