South Korean Network Hits 3.8Gbps Download Speed over LTE Network
Published on: 11th Jun 2014
Nokia says that it has reached a peak download speed of just under 3.8Gbps in a live South Korean mobile network.
The test, on the SK Telecom network involved aggregating 10 spectrum frequencies allocated for both LTE variants for a massive 200 MHz of bandwidth.
"This significant throughput achievement builds on our long-term collaboration with Nokia to make the most of TDD-FDD converged technologiess," said Alex Jinsung Choi, Executive Vice President and Head of ICT R&D Division at SK Telecom.
The throughput was achieved with Nokia's Single RAN solution including the Flexi Multiradio 10 Base Station, enhanced with software to aggregate carriers on both TDD and FDD LTE spectrum and to implement LTE-A MIMO technology.
There are significant benefits for operators in all geographical regions in combining their TDD and FDD LTE spectrum resources, one being the increased capacity for downlink and uplink data-intensive applications such as video streaming - and also the ability to eliminate supplementary downlink (SDL) completely.
With this demonstration, Nokia and SK Telecom have successfully achieving twice the amount of carriers and bandwidth specified by 3GPP, which foresees the aggregation of 5 carriers up to a total bandwidth of 100 MHz.
