T-Mobile, Nokia hit 1.175Gbps using Qualcomm's Snapdragon X20 LTE modem
T-Mobile's 4G LTE network was employed by Nokia and Qualcomm on Friday, to send data at speeds of 1.175Gbps. The test was run on 60Hz downlink spectrum and used 3x carrier aggregation to increase the capacity of the network. The device used in the test was powered by the Snapdragon X20 LTE modem, and included 4 x 4 MIMO to increase the number of connections between the device transmitting the data, and the device receiving it. It also included 256QAM, a technology that helps T-Mobile achieve gigabit speeds. A single Nokia 4.9G AirScale Base Station was used in the testing.
"Using the Snapdragon X20 LTE modem we are breaking through the gigabit barrier, further enhancing network capacity and real user data rates. And working with Nokia and T-Mobile, using our second-generation Gigabit LTE modem, we've now shown the steady strides we are making as we progress on the path to 5G. User devices supporting these speeds are expected to be made commercially available in the first half of 2018."-Cristiano Amon, Executive VP, president CDMA technology, Qualcomm
LTE Cat. 18 phones (possibly including the Galaxy S9) with the Snapdragon X20 modem could end up with consistent download speeds of 100Mbps. All of this is taking place as carriers continue to test 5G. The next-gen wireless networks could see some commercial use as soon as 2019.
