Nokia breaks new world record for LTE with SK Telecom

News

Nokia has once more claimed a new world record speed for LTE, reaching a speed of close to 4Gbps through aggregating 10 spectrum frequencies across 200MHz of bandwidth with SK Telecom.

The vendor first demonstrated TDD FDD carrier aggregation earlier this year, aggregating spectrum resources on multiple frequency bands of TD-LTE and FDD LTE and showing a 50 to 100% increase in throughput depending on the level of availability of spectrum.

This time the record-breaking throughput was again achieved using Nokia’s Single RAN solution which includes its Flexi Multiradio 10 Base Station together with software to aggregate carriers on both TDD and FDD LTE spectrum and to implement LTE MIMO (multiple input multiple output) technology. At this speed a mobile broadband user could download a 5GB high definition film in under 11 seconds.

The vendor said the demonstration achieve twice the amount of carriers and bandwidth specified by 3GPP, which suggested aggregating five carriers up to a bandwidth of 100MHz.

Zhang Qi, Vice-President of TD-LTE at Nokia, said: “This amazing speed record shows that Nokia continues to maintain its position as a clear throughput leader in the TD-LTE arena. “Operators worldwide can be confident in our capability to tackle the increasing demands for not only faster download but also data upload speeds.”

Alex Jinsung Choi, Executive Vice President and Head of ICT R&D Division at SK Telecom, said: "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 proof point of our continued leadership in providing the fastest connections and the highest quality for subscribers who use advanced data services."
