Iridium and Mlink Initiate Live Testing of Next-Gen IoT Chipset for Global Connectivity

In a significant advancement for IoT technology, Iridium Communications Inc. has collaborated with Mlink Technology Inc. to initiate live testing of the MS150-IR IoT-NTN chipset. This chip is designed specifically to support Iridium’s NTN Direct service, aimed at extending low-power IoT connectivity across the globe where traditional terrestrial networks fall short. During an announcement made on June 24, 2026, Iridium detailed the progress of Mlink in transitioning from laboratory tests to live, on-air testing, marking a pivotal moment in the deployment of satellite communication technologies.

The MS150-IR chipset is a derivative of the MS150 chipset family, marking it as a dedicated tool for Iridium’s application. With the importance of satellite networks in mind, the integration of Iridium NTN Direct not only enhances the existing ecosystem but also provides device manufacturers and mobile network operators (MNOs) with a unique chance to tap into global satellite communication without additional terrestrial infrastructure. Through this innovative approach, users can leverage satellite connectivity in various sectors including, but not limited to agriculture, logistics, and utilities.

Expanding Connectivity with Mlink’s Chipset

Mlink's entry into the Iridium NTN ecosystem reflects the growing collaboration among chipset providers aimed at enabling the 3GPP standards-based non-terrestrial network. The potential certification and availability of the MS150-IR chipset are anticipated by the end of 2026, which will provide numerous partners and customers with advanced solutions for global NB-IoT and device-to-device (D2D) connectivity.

Tim Last, Executive Vice President of Iridium, expressed enthusiasm regarding Mlink's successful transition to live testing, noting, "This achievement demonstrates the technical maturity of both teams and the readiness of Iridium NTN Direct." The emphasis on certification of the MS150-IR is a testament to the commitment both companies hold in ensuring quality, compliance, and performance before bringing products to market.

Zhiping An, Co-Founder of Mlink, acknowledged the importance of this collaboration, stating, "Having the opportunity to collaborate with Iridium in the emerging NTN field is a tremendous opportunity for Mlink." Mlink’s dedication to developing a comprehensive reference design kit highlights its intent to assist customers in speeding up product development and commercialization processes, further streamlining access to reliable satellite connectivity solutions.

The Shift Towards Global IoT

Iridium NTN Direct operates using a network of 66 cross-linked Low Earth Orbit (LEO) satellites, making it possible to provide low-latency services worldwide. By utilizing this unique infrastructure, Iridium's services are ideally suited for IoT applications including asset tracking, logistics, and remote monitoring, enhancing reliability in areas where terrestrial service is limited.

This partnership not only helps bring satellite communication to the forefront of the IoT era but also eases the integration process for chipset vendors, module manufacturers, and network operators. By reducing the technical and commercial hurdles associated with satellite connectivity, Iridium NTN Direct empowers partners to enhance coverage and reliability of their networks and services.

As this testing progresses, the industry is keenly watching the developments in the partnership between Iridium and Mlink. This initiative reinforces both companies' positions as leaders in satellite communication technology and paves the way for broader applications and innovations in IoT connectivity.
