Samsung’s Galaxy S27 Ultra may benefit from Qualcomm’s new 5G model, the X105. Qualcomm unveiled the modem at MWC 2026, promising a big leap in wireless performance, efficiency, and satellite connectivity. The company may integrate the modem into its next-gen Snapdragon 8 Elite Gen 6 processor coming later this year.

The X105 touts improvements in speed, reliability, and spectrum efficiency across both sub-6GHz and mmWave 5G bands. On paper, the new modem delivers peak download speeds up to 14.8Gbps and upload speeds up to 4.2Gbps. While real-world performance depends on carrier networks, these figures indicate stronger headroom for high-density urban environments and next-gen 5G deployments.

Qualcomm also claims major improvements in power efficiency, with the new RF transceiver paired with the X105 modem consuming up to 30% less power. This could translate into better battery life during streaming, gaming, and large downloads. The modem also adds quad-frequency GNSS support, improving location accuracy, especially useful for navigation, delivery services, and outdoor tracking.

Moreover, its on-device AI capabilities can predict and optimize network conditions in real time. Device makers like Samsung can use AI APIs from Qualcomm to fine-tune connectivity behavior, including intelligently switching networks, managing signal stability, and optimizing data flow.

Satellite connectivity and emergency support

The X105 supports NR-NTN (New Radio Non-Terrestrial Network), enabling direct communication with Low-Earth Orbit satellites. Compatible devices can make calls, send texts, and access data services even where traditional cellular coverage is unavailable. It also supports NB-IoT fallback connectivity, allowing limited messaging in challenging environments like elevators or underground parking garages.

If integrated into the Snapdragon 8 Elite Gen 6, the X105 could make it to Samsung’s Galaxy S27 Ultra. That said, there are rumors that the next Ultra could feature an Exynos processor. We should get a clearer picture in the coming months.
