Nokia and Singapore's StarHub have successfully tripled peak upload speed to 150Mbps over the operator's 4G network, in a trial using carrier aggregation technology and the 64 quadrature amplitude modulation (QAM) technique.
Following the trial, StarHub will introduce the technology commercially in the Marina Bay and Orchard areas of Singapore in time for the city state's year-end celebrations, allowing customers with compatible devices to have a smoother mobile data experience while sharing high definition videos and photos in real time. At such speeds which are three times faster than what most 4G networks offer today, a 200MB 4K resolution video can be uploaded to the Internet in as little as 11 seconds.
The speed achievement was made possible by Nokia's carrier aggregation technology, which aggregated spectrum in the 1800MHz and 2600MHz bands together with 64 QAM. Carrier aggregation is a technique used in 4G LTE-Advanced standards to allow non-contiguous bands of spectrum to be bonded to create wider channels, resulting in faster 4G speeds. Trial was done using compatible mobile devices with 4G LTE-Advanced technology (Cat. 13).
