Iridium Circuit Switched Data (CSD)

Asynchronous, Circuit-Switched, Bi-Directional

An asynchronous, circuit-switched, 2400bps, bi-directional service that allows for dial-up services. It can be used for larger amounts of data, including files of dozens or hundreds of megabytes.

Real Time, Simultaneous Connections

Ideal for applications where a limited number of field devices need to send their data a few times per day, or where the user, from a central location, reaches out to the field applications to retrieve their data.

  • Global Availability
  • A mesh of 66 active Low-Earth Orbit Iridium satellites blankets the Earth, providing reliable coverage from pole-to-pole

  • Two-Way Connectivity
  • Gain insights and send over-the-air commands for business operations and remote assets anywhere in the world

  • Real-Time
  • Iridium’s LEO network enables low-latency connections through shorter transmission paths than GEO networks

  • Range of Module Options
  • Small, light-weight, low-power, and low cost options to deliver Iridium CSD through your custom solutions

  • Simultaneous Connections
  • Similar to placing a phone call, CSD uses circuit-switching tech via a dial‐up modem & ISDN for low‐bandwidth data transfer, to enable a host application to originate/terminate numerous connections
