Satellite + LTE‑MModule

LTE‑M where there's coverage and Iridium Short Burst Data (SBD) satellite where there isn't, with GNSS built in, so devices report from anywhere on Earth.

  • Switches between LTE‑M and satellite on its own
  • Low-power, two-way Iridium SBD messaging
  • Global Iridium coverage, pole to pole
  • Built-in location from GPS, GLONASS, Galileo and BeiDou

Jooni Satellite + LTE-M module

Satellite + LTE‑M

Easy to integrate, quick to deploy, and ready to scale

A container ship leaving port for open ocean
Your app
3‑in‑1
LTE‑M, Iridium satellite and GNSS on one module, with just two antennas to fit.
Automatic failover
Uses LTE‑M where there's coverage and switches to Iridium SBD where there isn't, with no logic for you to write.
Global coverage
Iridium reaches the entire globe, oceans and poles included, so devices report from anywhere.
Satellite-ready data
Readings are compressed on the module, so they fit Iridium's short messages and use less airtime.
Edge memory
A time-series database on the module holds every reading through outages and power loss until it's back online.
Built to scale
Jooni Cloud is ready at power-up: fleet management, over-the-air updates and routing to any endpoint.

Satellite + LTE‑M

Inside the module

Interfaces

Serial API. Your device talks to the module through a simple serial API.
Command line. Set up and test the module over USB while you develop.
GPIO. Spare pins for your own signals and controls.
Reset + Enable. Hardware pins let your device reset or enable the module.

Intelligence

Jooni firmware

One API across the Jooni module family

Compression. Readings are compressed before they're sent, saving airtime and power.
Store and forward. Readings wait on the module during outages, then send.
Network routing. When one network drops, the module switches to another by itself.
Efficiency. Deep sleep between transmissions means battery-powered devices run longer.
Over-the-air updates. New firmware arrives over the air, with no site visit.
Cloud-synced settings. Change a setting in Jooni Cloud and the module picks it up.
Onboard storage. Data stays on the module, even through power loss.

Wireless communication

Satellite. Short messages go over Iridium, with coverage anywhere on Earth.
Cellular. Works on LTE-M wherever there's coverage, for lower-cost sends.
GNSS location. GPS, GLONASS, Galileo and BeiDou give each device its own position, anywhere.
Antenna ports. One antenna for satellite and GNSS, and one for LTE-M.

Cloud

Jooni Cloud

Included with every module

Fleet management. See every device's status in one place.
Remote configuration. Control any device and roll out updates from anywhere.
Data to your apps. Readings flow to your own systems through the APIs.

Frequently asked questions

  • Over Iridium Short Burst Data, each message carries up to 340 bytes from the device and 270 bytes to it, which suits readings, alerts and commands. Larger transfers, such as firmware updates, are best scheduled over cellular.

  • Iridium covers the entire globe, including the oceans and polar regions, so the module can report from sites with no cellular service.

  • For satellite and GNSS, yes. The satellite and GNSS antenna needs an unobstructed view of the sky. Cellular has no such requirement, so the module can still use LTE-M where the sky is blocked.

  • Two: one shared by satellite and GNSS, and one for LTE-M.

  • GPS, GLONASS, Galileo and BeiDou.
