Dual-mode 5G for SA/NSA
Ready for the next phase of 5G
5G networks are fast expanding as service providers are beginning to deploy standalone networks for faster, more reliable connections. Unlike non-standalone networks (NSA), which utilize existing 4G infrastructure along with 5G connectivity, standalone (SA) networks are built from the ground up for 5G to power the full deployment of smart, connected services. Exynos Modem 5123 supports both SA and NSA networks to deliver not just faster data transfer speeds but all the benefits of 5G connectivity.

Multi-mode modem
Multiple modes in a single chip
In addition to 5G, Exynos Modem 5123 supports a wide range of legacy networks, including 2G (GSM, CDMA), 3G (WCDMA, TD-SCDMA, HSPA), and 4G (LTE-FDD, LTE-TDD). Support for legacy networks all come in a single chip, meaning there is no need for additional modems and adds flexibility to device designs. In LTE mode, the modem provides enhanced speed and features, delivering downlink speed of up to 3.0Gbps via 8CA and supports up to 1024-QAM. By offering multi-network support, the Exynos Modem 5123 promises to bring seamless connectivity to everyone.


Enhanced power efficiency
Stay connected for longer
Manufactured with Samsung’s cutting-edge 7nm EUV process, Exynos Modem 5123 provides enhanced performance with lower power consumption. EUV technology creates finer circuits and denser patterns with extreme ultraviolet lithography, enabling the modem to integrate more components inside the chip for faster, more energy-efficient performance. The result is a 30 percent improvement on average in power efficiency compared to its predecessor. In the era of 5G, where more services and applications will require always-on connectivity, Exynos Modem 5123 ensures mobile devices to stay connected around the clock and maintain peak performance with longer battery life.
