China Mobile achieves peak rate of 1Gbps on Pre5G gigabit network

China Mobile VoLTEChina Mobile has achieved peak rate of 1Gbps during a demonstration using Pre5G gigabit rate solution in TD-LTE network conducted by ZTE and Qualcomm — in Quanzhou, Fujian.

They tested Quanzhou Mobile TD-LTE network with multi-carrier aggregation, 4×4 MIMO, 256QAM and other industry advanced technology combinations, showing that the peak rate of the network can reach 1Gbps.

China Mobile and ZTE also verified the Pre5G gigabit solution by utilizing Qualcomm Snapdragon 835 chip and the peak rate reached 700 Mbps with a 10-stream data transmission on a single phone.

5G should support a user-experience data rate of 0.1–1 Gbps, said the IMT-2020 (5G) promotion group in a white paper on 5G vision and requirements.

Giga+ mobile broadband (MBB), one of ZTE’s four core Pre5G technologies,uses massive multiple-input, multiple output (MIMO), multi-carrier aggregation, and high-order modulation technologies to improve spectrum efficiency and network-wide capacity, achieving a peak rate higher than 1 Gbps.

Earlier, Quanzhou Mobile and ZTE launched the deployment of 3D-MIMO in big video environments. With 16 commercial terminals connected, the single-carrier downlink peak cell rate was close to 730 Mbps, and for the first time, the single-carrier 16-stream downlink peak rate of 3D-MIMO reached 700 Mbps, equalling a three-carrier rate up to 2.1 Gbps.

By using 4×4 MIMO, multi-carrier aggregation, and 256 quadrature amplitude modulation or QAM technologies, as well as chips in the commercial network, this solution improves the efficiency of the network spectrum without increasing bandwidth.

Providing a user data rate of 1 Gbps or above, this solution also provides virtual reality (VR), cloud-based storage, free lossless audio codec (FLAC) music, and HD video services.

Pre5G enhances system capacity by up to eight times, average user bandwidth by five times, and the number of connections per unit area by 100 times compared with 4G.

More than 60 networks in more than 40 countries, including China, Japan, Austria, Singapore, Spain, Malaysia, Thailand, and Indonesia, have already deployed Pre5G-related products and solutions.
