Galaxy S27 Ultra could have faster 5G chip with built-in satellite connectivity

Qualcomm has announced its latest 5G modem, the X105, at Mobile World Congress (MWC) 2026. The new modem is expected to be used in Snapdragon 8 Elite Gen 6 series processors, which will likely power the Galaxy S27 Ultra when it launches early next year. With the X105, the device will offer improved wireless connectivity performance.

The X105 succeeds Qualcomm’s X85 modem, which was used in the Snapdragon 8 Elite Gen 5 processor. It is the company’s first modem to support 3GPP Release 19, which lays the groundwork for 6G networks in the future. However, it is still a 5G modem. It supports 5G Advanced and introduces several enhancements.

The modem is expected to debut in the third quarter of 2026 alongside the Snapdragon 8 Elite Gen 6 series. This combination will likely power the Galaxy S27 Ultra.

In terms of performance, the Qualcomm X105 delivers faster 5G data speeds. It supports peak download speeds of up to 14.8Gbps, including up to 13.2Gbps on sub-6GHz networks, and peak upload speeds of up to 4.2Gbps. The new RF transceiver paired with the modem consumes up to 30% less power. Additionally, it supports quad-frequency GNSS, which improves location accuracy.

The X105 also incorporates on-device AI capabilities designed to predict and optimize network connectivity. Qualcomm is providing AI APIs that allow smartphone manufacturers to further optimize connectivity performance.

Built-in satellite connectivity for emergency communications

One of its key features is support for New Radio Non-Terrestrial Network (NR-NTN) connectivity. This allows compatible devices to connect directly to Low-Earth Orbit (LEO) satellites for 5G services. Users can make and receive calls, send and receive text messages, and access data for apps and web browsing through satellite connectivity where conventional cellular networks aren't available.

The X105 also supports NB-IoT networks, which can serve as a fallback when traditional cellular or satellite connectivity is unavailable. This enables messaging services, including RCS, in areas where cellular signals are blocked or weak, such as elevators and underground parking garages.
