MQTT Privacy & Exposure Analysis

Analysis of privacy features and exposure risks when packet is shared via MQTT

Exposure Level: Broadcast
Privacy Features:
  • āœ“ Direct LoRa transmission (not via MQTT)
  • āœ“ Gateway node ID tracked
  • āœ“ Reduced position precision: ~2900.0m accuracy
Exposure Risks:
  • āš  Visible to all nodes on channel
  • āš  Default channel - no encryption
  • āš  Packet visible to MQTT subscribers
  • āš  Multi-hop path visible (3 hops)
  • āš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !45ea5a1b
Position Precision: 13 bits (~2900.0m accuracy)
Position precision meters: 2900.0
Signal Metrics: RSSI: -107.0 dBm
SNR: -15.00 dB
