Snapdragon X20 LTE Modem

Introducing maximum modem speed. Meet the world’s first-announced modem to support Cat 18 LTE, the Qualcomm® Snapdragon™ X20 LTE modem. With the fastest LTE download speeds yet, our second generation Gigabit LTE modem, built in a leading-edge 10nm FinFET process, is yet another step on the path to 5G—helping more operators around the world bring fiber optic speeds wirelessly to your device for the latest generation of mobile experiences.

Breaking the Gigabit barrier.

By supporting speeds up to 1.2 Gbps, the Snapdragon X20 LTE modem is up to 20% faster than the previous generation, and also provides support for Cat 13 upload speeds up to 150 Mbps. With this kind of speed, the Snapdragon X20 LTE modem can bring new experiences to your mobile device at lightning speed—so you can experience immersive 360-degree video, connected cloud computing, rich entertainment and instant apps at the speed you need.

Going global with Gigabit.

The Snapdragon X20 LTE modem is designed to provide vastly expanded spectrum flexibility compared to the previous generation. With support for up to 5x carrier aggregation, up to 4x4 MIMO on three aggregated carriers and up to 12 LTE spatial streams, it can help many more operators around the world deploy Gigabit LTE service. Additionally, with support for License Assisted Access (LAA), Snapdragon X20 helps allow operators with as little as 10MHz of licensed spectrum tap into unlicensed spectrum to deploy Gigabit LTE, relieving congestion in crowded areas. So, even at the busiest times, you can get the service you need, when you need it, on your device.

Convenience and clarity.

Snapdragon X20 is the first LTE modem to support Dual SIM Dual VoLTE (DSDV)—engineered to bring you the clarity of HD and Ultra HD Voice with the convenience and flexibility of dual SIM. No longer should having a dual SIM phone mean sacrificing call quality on the second SIM. And of course, you can select to use the blazing fast Category 18 LTE data speeds on either SIM.

New spectrum. New opportunities.

Snapdragon X20 supports the new Citizens Broadband Radio Service (CBRS) band in the United States. CBRS provides a unique new way of sharing spectrum that can allow operators to tap into a vast spectrum resource to improve their service, or allow new entrants to setup private LTE networks.
