The Shenzhen branch of China Mobile has claimed that it has achieved the ‘world’s first’ 1Gbps cellular throughput speeds using only 20MHz of time division duplex LTE (TD-LTE) spectrum. The technical field trial saw the mobile giant team up with domestic vendor Huawei to test a Massive multiple-input, multiple-output (MIMO) solution on commercial user equipment. China Mobile notes that the solution can effectively resolve congestion in LTEnetworks and lay a solid foundation for the smooth evolution to 5G.
