What it shows

  • Hardware trackers emit high-frequency telemetry independently of assets.
  • Vehicles bind to active GPS devices through swappable associations.
  • Geofences evaluate point-in-polygon coordinates to fire alert triggers.

The takeaway

Decouple physical vehicles from tracker hardware to survive hardware swaps.
