China Mobile, ZTE and Qualcomm have jointly completed a demonstration of Pre5G gigabit capability over a commercial TD-LTE network.
The trial in Quanzhou, Fujian involved incorporating multi-carrier aggregation, 4x4 multiple input multiple output (MIM), 256 quadrature amplitude modulation (QAM) and other pre5G technologies to boost the peak data rate of the network to 1Gbps.
The trial used ZTE mobile equipment and commercial Qualcomm chips. Using these chips peak data rate reached 700Mbps with a 10-stream data transmission on a single phone.
China Mobile's subsidiary in the city Quanzhou Mobile previously collaborated with ZTE on the commercial deployment of 3D-MIMO in big video environments, achieving a single-carrier downlink peak cell rate of close to 730Mbps with 16 commercial terminals connected.
“This field test by Quanzhou Mobile and ZTE is another breakthrough result, indicating a step forward in single-user rate enhancement,” ZTE said in a statement.
“By using 4×4 MIMO, multi-carrier aggregation, and high-order baseband modulation technologies, as well as commercial chips in the commercial network, this solution significantly improves the efficiency of the network spectrum without increasing bandwidth, and provides a user data rate of 1 Gbps or above.”
