Rohde & Schwarz and Huawei Technologies Co., Ltd., today announced the successful demonstration of 1.2 Gbps LTE-A-Pro downlink throughput, using Huawei Kirin 970 SoC, the industry's first smartphone SoC to support category 18 (1.2 Gbps).
In the Rohde & Schwarz and Huawei lab, the 1.2 Gbps download speeds were achieved by using a combination of up to three downlink FDD carriers on which carriers can be received separately on four transmission layers (4x4 MIMO, or multiple in, multiple out) and 256QAM data modulation. 3GPP 4x4 MIMO mandates four receive antennas on the device side, so four RF connections are needed.
