ESPOO, Finland -- Nokia and SK Telecom have again demonstrated the unparalleled benefits of converging the TDD and FDD LTE spectrum. By aggregating 10 spectrum frequencies allocated for both LTE variants for a massive 200 MHz of bandwidth, Nokia and SK Telecom reached a throughput speed of 3.78 Gbps. At this speed, a mobile broadband user can download a full-length 5 GB high-definition (HD) movie in just 11 seconds.

“This significant throughput achievement builds on our long-term collaboration with Nokia to make the most of TDD-FDD converged technologies. It is also a proofpoint of our continued 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. “Once again, SK Telecom and Nokia have set a benchmark for the global telecoms industry.”

The unmatched throughput was achieved with Nokia’s Single RAN solution including the high-capacity 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. With this demonstration, Nokia and SK Telecom have pushed the boundaries of carrier aggregation by 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.
