 As the world’s first BGAN M2M terminal designed to operate on both Inmarsat BGAN (Broadband Global Area Network) and cellular 2G/3G/LTE networks, EXPLORER 540 delivers always available connectivity for critical monitoring and control applications.

The BGAN M2M service uses Inmarsat BGAN to provide a reliable, global, two-way IP data service. It is designed to connect monitoring and control applications in remote, unmanned locations, providing visibility and management of those assets. By combining BGAN M2M with cellular connectivity in the same terminal, EXPLORER 540 gives users the opportunity to choose the best carrier for any location.

Industry Uses

  • Utility smart grid – real-time control with about 1200 millisecond latency.
  • Weather, environmental, seismic warning sensors over a global area.
  • Pump/valve monitoring and control – access remote devices, screens, parameters.
  • Asset monitoring – trigger switches, door open, motion detector, alarm send information.
  • Remote video surveillance – 448 Kbps speeds allow for fast refresh-rate of images real-time.
  • Credit card processing – its low power and small profile make it an ideal alternative to satellite dishes.
  • Low- or high-bandwidth SCADA or M2M devices.
  • Any remote device that communicates over a standard TCP-IP internet connection.
