Nokia and SK Telecom have tested the aggregation of ten 20 MHz spectrum bands to achieve a record LTE throughput speed of 3.78 Gbps.
The test used 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.
The companies noted that their record performance demo utilized 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.
“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.”
“This amazing speed record shows that Nokia continues to maintain its position as a clear throughput leader in the TD-LTE arena”, said Zhang Qi, vice president of TD-LTE at Nokia. “Operators worldwide can be confident in our capability to tackle the increasing demands for not only faster download but also data upload speeds.”
