Telecom network operator M1 has achieved peak download speeds of more than 1Gbps, and peak upload speeds in excess of 130Mbps — on 4G networks.
LTE CAT9 devices support download speeds of up to 450Mbps and upload speeds of up to 50Mbps. The trial is part of M1’s strategy to deliver increased mobile upload speeds to meet expectations of its mobile customers in Singapore.
Chinese telecom network vendor Huawei has supported M1 for conducting the trial in M1’s LTE Advanced test lab in Singapore using its existing hardware infrastructure and a prototype CAT14 device.
What technology implemented during trial:
# Higher Order Modulation (256QAM) technology that increase the numbers of bits to be carried over the same LTE symbol
# LTE-A 4×4 MIMO technology that enables the download speed to double from existing 2×2 MIMO configuration
# 3CC Tri-Band Downlink Carrier Aggregation that allows the use of three spectrum bands simultaneously to improve the downlink throughput speed
# 2CC Uplink Carrier Aggregation that allows aggregation of two spectrum bands simultaneously to improve the uplink throughput speed
In order to achieve better results, M1 integrated four advanced network technologies: 3CC aggregation, 4×4 MIMO (Multiple-Input Multiple-Output), Higher Order Modulation 256 QAM (Quadrature Amplitude Modulation) and 2CC uplink carrier aggregation for the trial.
“Through technology innovation, we can further stretch the capability of current 4G technology, prior to the advent of 5G technology, to achieve an incredible peak download speed of more than 1Gbps,” said Denis Seek, chief technical officer of M1.
“The trial marks the beginning of 4.5G era in Singapore, demonstrating Huawei and M1’s innovation in delivering the benefits of the latest mobile technology advances to Singapore consumers, for instance, in enabling machine-to-machine connections and improving HD video experience,” said Wang Jun, president of LTE Networks of Huawei Technologies.
