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: ShortFast
  • ✓ Gateway node ID tracked
  • ✓ Reduced position precision: ~2900.0m accuracy
Exposure Risks:
  • âš  Visible to all nodes on channel
  • âš  Packet visible to MQTT subscribers
  • âš  Multi-hop path visible (4 hops)
  • âš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !fb13094d
Position Precision: 13 bits (~2900.0m accuracy)
Position precision meters: 2900.0
Signal Metrics: RSSI: -125.0 dBm
