Exposure Risks:
  • âš  Visible to all nodes on channel
  • âš  Default channel - no encryption
  • âš  Packet visible to MQTT subscribers
  • âš  Full GPS precision shared
  • âš  RF signal metrics exposed (location inference possible)
MQTT-Specific Fields
Gateway ID: !fb13094d
Position Precision: 32 bits (~1.0m accuracy)
Position precision meters: 1.0
Zero Hop Policy: Enabled
