Iridium introduced the Iridium 9604, a compact satellite IoT module that combines Iridium Short Burst Data (SBD) satellite service, LTE-M cellular connectivity, and GNSS positioning in a single 16×26×2.4 mm package, featuring integrated multi-mode radios and a unified AT command set. The module launched commercially after an oversubscribed beta program and is built on the u‑blox SARA‑R5 platform to reduce component count and board footprint.
The 9604 ships with an SDK, reference designs and a development kit to speed integration, and it supports dual-mode network selection so devices can use cellular where available and switch to satellite beyond terrestrial coverage. Iridium positioned the product alongside its broader IoT stack, including NTN Direct and Iridium Messaging Transport, as part of a multi-path connectivity strategy.
For hardware teams and fleet or asset operators, the 9604 simplifies BOM, trims PCB area by about 60%, and eases power design, making global, location-aware tracking and remote monitoring more cost-effective. By collapsing three connectivity functions into one module, the product addresses scaling challenges for high-volume IoT deployments.

Trend Themes
-
Multi-mode Convergence — Combining satellite SBD, LTE‑M, and GNSS into one module reduces component count and creates opportunities for unified connectivity stacks that disrupt traditional multi-module designs.
-
Miniaturized All-in-one Connectivity — A 16×26×2.4 mm form factor that collapses three radios into one presents a pathway for ultra-compact devices that significantly lower BOM, PCB area, and power budgets for high-volume deployments.
-
Multi-path Network Resilience — Dual‑mode network selection and integration with NTN offerings point to resilient, seamless roaming architectures that challenge single-network-dependent IoT solutions.
Industry Implications
-
Fleet Management — For fleet operators, compact multi-mode modules promise pervasive global tracking with fewer hardware variants, disrupting existing telematics hardware lifecycles and procurement models.
-
Asset Tracking and Logistics — Logistics providers could see simplified global shipment visibility from modules that switch between cellular and satellite coverage, reducing the need for separate long‑range hardware platforms.
-
Wearable Health and Safety — Tiny integrated connectivity and GNSS in a single package enable personal safety devices with continuous global location reporting and lower device size and power constraints than current multi-component designs.
