With the caveat that “hero” lab tests and selected field trial results typically do not translate to commercially-available “whole network” performance, T-Mobile US, Nokia and Qualcomm Technologies, Inc., a subsidiary of Qualcomm Inc., exceeded gigabit-per-second speeds using commercially-available 4G LTE technology.
In tests at T-Mobile US laboratories, download speeds of 1.175 Gbps Gbps were achieved on T-Mobile’s LTE network using Nokia’s 4.9G network, the Nokia AirScale Base Station and Qualcomm’s Snapdragon X20 LTE modem. That test nearly hit the theoretical maximum downlink speed for the X20 LTE modem.
The test also featured use of 4X4 MIMO, 256 QAM and three carrier aggregation across 60 MHz of downlink spectrum on T-Mobile’s network.
The larger point is that the evolution of 4G networks to gigabit speeds is considered a foundation for the coming 5G network, which will use most of the new techniques (MIMO, small cells, channel bonding, spectrum aggregation) being developed for gigabit LTE.
The latest test is part of the evolution of 4G towards 5G.
