Project Stardust: Revolutionizing IoT and D2D Communication


Iridium Communications Inc., a pioneer in global satellite voice and data communication, has recently unveiled its ambitious Project Stardust. This innovative venture aims to integrate 3GPP 5G standards-based Narrowband-Internet of Things (NB-IoT) into its Non-Terrestrial Network (NB-NTN) service. This integration will utilize Iridium’s current satellite infrastructure, marking a significant step in the evolution of Direct-to-Device (D2D) strategy and IoT services.

Strategic Collaboration and Industry Impact

Iridium’s initiative opens a unique window for collaboration with smartphone manufacturers, Original Equipment Manufacturers (OEMs), chipmakers, mobile network operators (MNOs), and IoT developers. These partnerships aim to integrate industry requirements directly into the Iridium network, enhancing the satellite constellation’s flexibility and capability. Matt Desch, Iridium’s CEO, highlights this development as a testament to Iridium’s network versatility and its leading position in adopting a standards-based approach for global coverage.

Advanced Capabilities of NB-IoT Offering

The company is tailoring its initial NB-IoT offerings to support 5G NTN messaging and SOS capabilities for a variety of devices, including smartphones, tablets, and cars. This advancement will allow manufacturers to integrate satellite connectivity into standard devices, leveraging Iridium’s globally allocated spectrum. The low-latency user experience provided by Iridium’s LEO satellites will significantly enhance connectivity solutions.

Supporting Global Emergencies and IoT Ecosystem

Iridium’s network, supporting around 1,300 SOS and emergency incidents globally each year, demonstrates its readiness to expand this capacity to new devices. The company emphasizes its commitment to facilitating rapid product development and certification for chipmakers and IoT developers. With a network of approximately 500 partners, Iridium offers a flexible integration approach, catering to proprietary, standards-based, or dual-solution needs.

Competitive Advantages of Iridium’s Satellite Constellation

The company’s fully crosslinked LEO architecture and global L-band spectrum stand out against other LEO and geostationary satellite networks. Accredited for safety of life services, Iridium prides itself on reliability, unaffected by the limitations and challenges faced by geostationary systems.

Two Decades of Leadership in Satellite IoT

Iridium, with over two decades of experience, has built an unrivaled partner ecosystem, serving more than 2.2 million users worldwide. The company’s consistent subscriber growth and a substantial IoT customer base underscore its role as a trusted provider in satellite IoT and personal communications. The low power requirements and comprehensive coverage of the Iridium network make it an ideal choice for the upcoming NB-IoT NTN service.

Fostering Future Developments and Partnerships

Iridium is actively engaging with companies specializing in D2D and IoT to integrate their use cases and needs into the upcoming service. With testing anticipated to start in 2025 and service launch expected in 2026, Iridium is at the forefront of shaping the future of global IoT and D2D connectivity.

Organizations globally are tapping into the vast potential of the Operational IoT market, from transforming weather monitoring in remote mines to ensuring safe drinking water in African communities. The real game-changer is the integration of reliable, cost-effective satellite connections, predicted to rise to tens of millions by 2030. These connections make it possible to transmit data periodically rather than in real-time, reducing costs and meeting the specific needs of industries like agriculture, shipping, and environmental monitoring. The challenge for Systems Integrators (SIs) is to ensure their Satellite IoT deployments are not only technologically viable but also commercially successful. Ensuring robust satellite coverage, cost-effective deployment, and prolonged battery life are essential to this business case. Forward-thinking SIs have already started their journeys, optimizing Satellite IoT solutions, proving its business worth, and preparing for large-scale deployments.

The space industry should reach $1 trillion in annual revenue by 2040, according to a report by Citibank analysts. At the same time, a recent report from Inmarsat and Globant estimates the world could reach net zero up to ten years ahead of the 2050 target if industries make the most of existing and emerging space-based satellite technology. Suffice to say, space can offer an array of solutions for sustainability, security and connectivity. Mobile communications have evolved from generation to generation, adding better capabilities, and the trend is far from being over. The sixth generation is already in the making, and the core driving factors for 6G will revolve around enhancing human communication, including immersive experience, telepresence, multimodal collaboration and interaction. 6G will also aim to enhance machine communication, with the focus on autonomous machines and vehicles capable of sensing their surrounding environment in real time (network as a sensor). This article expands on how small satellites will augment the future of communications that starts already today.
