Qualcomm demonstrates their X16 Cat16 Gigabit LTE modem integrated in the upcoming Sony Xperia XZ Premium using Qualcomm Snapdragon 835 which features 4×4 MIMO (multiple input multiple output). The phone uses 4 LTE antennaes instead of the usual 2 to boost throughput speeds to 1Gbps using carrier aggregation. The technology is expected to be more power efficient since the faster downloads would finish quicker, effectively lessening the time cellular data is used.
