Singtel today launched a 450Mbps mobile network with the nationwide deployment of 4G LTE-Advanced service in Singapore. This speed enhancement is made possible by Singtel’s nationwide LTE network upgrade to support 256 Quadrature Amplitude Modulation, or 256 QAM. A pre-5G technology, 256 QAM increases the number of unique radio waveform shapes to carry up to 33.33% higher data and elevates spectral efficiency.

The 450Mbps service is available to all Singtel 4G customers at no additional charge. Customers with Samsung Galaxy S7 and Samsung Galaxy S7 edge will be able to get 450Mbps speeds starting today. LG V20 users will also be able to harness the higher speeds with a soon-to-be released software update. More compatible smartphone models are expected to be launched by early 2017.

Singtel and Ericsson have also demonstrated download speeds of up to 1Gbps in a live 4G network pilot at two sites in Pasir Ris. This ultra-fast download speed was achieved by deploying 256 QAM downlink, 4×4 Multiple Input Multiple Output (4×4 MIMO) and triple carrier aggregation technologies. 4×4 MIMO doubles the number of data paths between a cellular base station and mobile phones, delivering a speed boost of up to two times normal speeds.

Singtel will progressively rollout 4×4 MIMO technology on its network starting next year to deliver up to 1Gbps speeds at selected high-traffic locations. Supporting mobile devices are expected to be ready by end 2017.
