Nokia, SK Telecom achieve 3.78 Gbps throughput speed on converged TD and FD LTE spectrum

Nokia and SK Telecom have achieved a throughput speed of 3.78 Gbps on the converged TDD and FDD LTE spectrum.

The trial used combined 10 spectrum frequencies allocated for both LTE variants for 200 MHz of bandwidth.

The throughput speed of 3.78 Gbps enables mobile broadband users to download a full-length 5 GB high-definition (HD) movie in 11 seconds.

“This significant throughput achievement is a proofpoint of our leadership in providing the fastest connections and the highest quality for subscribers who use advanced data services,” said Alex Jinsung Choi, executive vice president and head of ICT R&D Division at SK Telecom.

SK Telecom to expand LTE speed

For the trial demonstration, SK Telecom used 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-Advanced Multiple Input Multiple Output (MIMO) technology.

The increased capacity for downlink and uplink data-intensive applications such as video streaming – and the ability to eliminate supplementary downlink (SDL) completely are some of the benefits by combining TDD and FDD LTE spectrum resources.
