Iridium Brings Hybrid Satellite, LTE-M and GNSS IoT Module to Commercial Availability
Iridium has made its 9604 IoT module and development kit commercially available, combining Iridium Short Burst Data satellite connectivity, LTE-M cellular and multi-constellation GNSS in a single compact module. The launch targets OEMs and developers building connected devices that must operate across both terrestrial and remote environments.
For many IoT deployments, the difficult part is not connecting a device when coverage is available. It is deciding what happens when coverage changes, when assets move between cellular and non-cellular regions, and when the device footprint cannot accommodate multiple radios, antennas and power-management paths without adding cost and engineering risk.
That is the problem Iridium is addressing with the commercial release of the Iridium 9604 module and its accompanying development kit. The module brings together Iridium Short Burst Data, LTE-M and GNSS positioning, giving device makers a pre-integrated hardware path for applications that need both terrestrial cellular connectivity and satellite reach.
The announcement is notable because it is not simply another satellite IoT modem or a cellular module with a positioning receiver added. Iridium is positioning the 9604 as a hybrid IoT building block that replaces three separate components: satellite communications, LTE-M and GNSS. According to the company, that integrated design can reduce board space requirements by 60 percent or more while simplifying RF routing, power architecture and firmware development.
Built on the u-blox SARA-R5 platform, the 9604 measures 16 mm x 26 mm x 2.4 mm and supports LTE-M Cat-M1, Iridium’s L-band satellite network and GNSS services including GPS, GLONASS, Galileo and BeiDou. The development kit is intended to let developers prototype, test and validate hybrid satellite, cellular and positioning applications before moving toward commercial device integration.
The key architectural distinction is control. Iridium says developers can manage the satellite, LTE-M and GNSS subsystems independently, using that separation to implement failover logic, location-aware connectivity decisions and application-specific routing strategies. In practical terms, this means the module is not forcing a single connectivity behavior on every device design. A tracking device, a remote sensor and a maritime monitoring unit may all use the same module, but make different choices about when to use LTE-M, when to use satellite messaging and how often to acquire a location fix.
That flexibility matters in hybrid IoT because satellite capacity, cellular airtime, battery consumption and reporting latency are not interchangeable design variables. A device that transmits over LTE-M whenever it is available and falls back to Iridium SBD outside terrestrial coverage will have different operational characteristics from a device that uses location or application state to decide when satellite communication is justified. The 9604’s value, therefore, is less about adding radios for their own sake and more about giving OEMs a smaller integration surface for those trade-offs.
The module also reflects a broader shift in satellite IoT. Dedicated satellite-only hardware remains relevant for remote and mission-critical use cases, but many industrial and logistics applications now require continuity across mixed network environments rather than a single access technology. Iridium’s own IoT portfolio now spans SBD modules, standards-based Iridium NTN Direct capabilities and larger-payload connectivity through the Iridium Certus 9704 module. The 9604 sits in a different part of that portfolio: compact, multi-mode IoT devices where small payloads, location awareness and coverage resilience are central requirements.
For OEMs, the commercial availability of the module and development kit could shorten the early engineering cycle by reducing the need to combine discrete cellular, GNSS and satellite components at board level. For system integrators, it may simplify solution design in sectors such as transportation, utilities, infrastructure, maritime and remote monitoring, where assets often cross the boundary between terrestrial and non-terrestrial coverage. Connectivity providers and service partners may also see more demand for service plans and management tools that account for cellular and satellite usage within the same device lifecycle.
The announcement should not be read as eliminating integration work. Hybrid connectivity still requires careful decisions around antenna design, power budgets, firmware behavior, data prioritization and commercial service models. But by making the 9604 and its development kit commercially available, Iridium is giving the IoT ecosystem a more packaged route into that design space, particularly for devices where global coverage is needed but board area and engineering resources remain constrained.
In a market where many satellite IoT announcements focus on future network capabilities or standards evolution, the 9604 is distinct because it is a commercially available module-level product aimed at near-term device development. Its significance lies in how it packages satellite, cellular and GNSS functions for OEM implementation, rather than in a promise of coverage alone.
