Snapdragon X12 LTE Modem

Qualcomm Snapdragon is a product of Qualcomm Technologies, Inc., and/or its subsidiaries.

More data and more connections.

The Snapdragon X12 LTE modem cranks peak download speeds up to 600 Mbps and peak upload speeds up to 150 Mbps, thanks to support for LTE Advanced carrier aggregation (3x in the downlink, and 2x in the uplink) and higher order modulation (up to 256-QAM in the downlink, and 64-QAM in the uplink). It even supports downloading data on 4 antennas simultaneously with support for 4x4 MIMO. That means lightning fast connections, quicker network response times, and richer app content.

Goodbye congestion.

With the help of LTE-U small cells, the Snapdragon X12 LTE Modem can access LTE connections in both licensed spectrum and unlicensed spectrum — boosting your connection speeds in normally congested areas.

The best of both worlds.

The Snapdragon X12 LTE Modem can automatically switch between LTE and Wi-Fi, picking the link that has the strongest signal quality and highest end-to-end speeds. That means better voice and video calls. Plus, if your operator supports the feature, the Snapdragon X12 LTE modem can even bond your LTE and Wi-Fi links together to boost download speeds with LTE + Wi-Fi Link Aggregation (LWA).
