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: ShortTurbo
  • ✓ Gateway node ID tracked
  • ✓ Reduced position precision: ~2900.0m accuracy
  • ✓ Zero-hop: direct from source to MQTT gateway
Exposure Risks:
  • ⚠ Visible to all nodes on channel
  • ⚠ Packet visible to MQTT subscribers
  • ⚠ RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !0d2388cd
Position Precision: 13 bits (~2900.0m accuracy)
Position precision meters: 2900.0
Zero Hop Policy: Enabled
Direct gateway connection
Signal Metrics: RSSI: -44.0 dBm
