Samsung Unveils Exynos 5410 5G Modem with Enhanced Satellite Connectivity for Galaxy S26
Samsung has revealed its latest 5G modem, the Exynos Modem 5410, designed to bring advanced satellite communication capabilities to future smartphones, including the anticipated Galaxy S26 series. This external modem will pair with the recently announced Exynos 2600 processor, marking a shift in Samsung's chipset strategy.
Technical Specifications and Performance
The Exynos Modem 5410 is fabricated on Samsung Foundry's 4nm FinFET process, which the company claims offers improved power efficiency over previous generations. It supports both mmWave and sub-6GHz 5G networks, achieving peak download speeds of up to 14.79Gbps while maintaining backward compatibility with 2G, 3G, and 4G networks.
Enhanced Satellite Communication Features
The most significant advancement in the Exynos Modem 5410 is its expanded satellite connectivity support. While the previous Exynos 5400 modem supported two satellite communication technologies (NB-IoT and NR NTN), the new modem adds LTE DTC (Direct-to-Cell) compatibility. This third satellite system enables devices to make voice and video calls, share locations, and send messages directly via satellites without relying on traditional cellular networks. This enhancement could prove crucial in remote areas or during emergencies where terrestrial network coverage is unavailable.
Security and Implementation
Security remains a priority with the Exynos Modem 5410. It incorporates ROM-based Hybrid PQC (Post-Quantum Cryptography) for reliable and secure communication, along with a dedicated Security Processor capable of encrypting sensitive data such as IMEI numbers. The modem is expected to be paired with the Exynos 2600 processor in the Galaxy S26 and Galaxy S26+ models in select global markets, continuing Samsung's regional chipset distribution strategy.
Conclusion
Samsung's Exynos Modem 5410 represents a notable step forward in mobile connectivity, particularly through its enhanced satellite communication capabilities. By supporting LTE DTC alongside existing satellite technologies, it enables more comprehensive off-grid communication features. When combined with the 2nm Exynos 2600 processor, this modem could help position the Galaxy S26 series as a leader in connectivity innovation, offering users greater reliability in diverse environments. As satellite connectivity becomes increasingly important in smartphone ecosystems, Samsung's latest modem demonstrates the company's commitment to advancing this technology.
