T-Mobile and its technology partners Nokia and Qualcomm today said they've reached peak download speeds in excess of 1.175 Gbps using LTE-A equipment in a lab. In order to reach these speeds, T-Mobile and its partners used the "4.9G" Nokia AirScale Base Station together with the Qualcomm Snapdragon X20 LTE modem mobile test device. The X20 supports Category 18 for theoretical peak downloads of 1.2 Gbps. The network ran 12 independent streams of LTE data and relied on 4x4 MIMO, 256 QAM, and three-channel carrier aggregation across 60 MHz of T-Mobile's network. T-Mobile says the test "demonstrated that commercially available 4G technologies can deliver unprecedented download speeds well beyond what customers experience today." T-Mobile and other carriers are developing 4.5G and 5G technologies even though the ITU has yet to define the standard's specifications.
