Globalstar and GCT Semiconductor Forge Strategic Partnership for IoT Connectivity

In a significant development in the telecommunications industry, Globalstar, Inc. (Nasdaq: GSAT), a prominent provider of mobile satellite and communications services, has announced a collaboration with GCT Semiconductor Holding Inc. (NYSE: GCTS), a leading designer of advanced 4G and 5G semiconductor solutions. The partnership aims to develop two-way satellite messaging systems that will enhance connectivity for Globalstar's mobile devices and modules. This collaboration was unveiled at the Mobile World Congress held in Barcelona from March 3 to 6, 2025.

The flagship product of this partnership is Globalstar's newly announced RM200M, which will utilize GCT's cutting-edge IoT chip, the GDM7243i. Future products are expected to incorporate GCT's 4G LTE chip, the GDM7243SL, and a 5G IoT-enabled chipset. This strategic choice allows Globalstar to effectively expand its satellite network capabilities and meet the growing demand for reliable connectivity solutions.

Alex Katko, VP of Product Engineering at Globalstar, emphasized the effectiveness of GCT’s GDM7243i for narrowband IoT applications, stating, “Globalstar evaluated many options for our next-generation product suite, and we selected GCT because GDM7243i with GDM7243SL was a compelling solution combo.” He noted that the combination of narrowband and low-power capabilities of the GDM7243i, along with the flexible multi-mode GDM7243SL, would enable seamless connectivity for Globalstar’s devices across cellular and satellite networks globally.

GCT's CEO, John Schlaefer, expressed enthusiasm about the partnership, stating, “GCT is thrilled to partner with a pioneering leader in satellite communications, a company poised for a bright future with numerous opportunities in this expanding industry.” He highlighted the potential of their advanced 4G chips and the intention to explore the non-terrestrial market with 5G products, aiming to lead in satellite communications technology.

Through this collaboration, Globalstar and GCT are positioned to develop a variety of LTE and IoT products that will significantly enhance Globalstar’s existing portfolio. This strategic partnership aligns with the growing demand for advanced tracking systems, satellite phones, and other IoT solutions in an increasingly connected world.

The partnership was showcased at the Mobile World Congress in Barcelona, where both companies presented their innovative solutions. Attendees were encouraged to visit GCT at Hall 5, stand 5J56, and Globalstar at Hall 2, stand 2C74, to explore the advancements in satellite and IoT technologies.

The partnership between Globalstar and GCT Semiconductor marks a pivotal moment in the evolution of connectivity solutions, combining satellite and cellular technologies to provide robust, two-way messaging systems. As they work together to develop next-generation products, both companies are set to play a critical role in shaping the future of telecommunications, making significant strides in the IoT and satellite communication sectors.

This collaboration underscores the importance of innovation and strategic alliances in meeting the increasing demands of a connected world, ensuring that essential services remain reliable, efficient, and accessible across various platforms.
