At the ITU Telecom World 2014, Nokia Networks, Ooredoo Qatar and China Mobile showcased what they claim is a record-breaking speed of 4.1 Gbps over TDD-FDD LTE.
Supported by the Global TD-LTE Initiative, the speed was achieved by combining TDD- and FDD-LTE spectrums and aggregating 10 carriers with 200 MHz bandwidth.
At this speed, operators can match and exceed the expectations of even the most demanding mobile users who would be able to, for example, download a full-length 5 GB high-definition (HD) movie in just 11 seconds and simultaneously upload a 5-minute 30 MB video clip from a concert in less than a second.
The record was achieved using Nokia Networks’ commercial single RAN Advanced hardware, including the Flexi Multiradio 10 base station (pictured) for high-capacity throughput. It also used software to aggregate carriers on both TDD- and FDD-LTE spectrums and LTE-Advanced Multiple Input Multiple Output (MIMO) technology.
Waleed Al Sayed, chief operating officer, Ooredoo Qatar, said: “We are building the biggest, fastest network in Qatar, so that customers across the country can access next-generation wireless data services. We are very proud that the first-ever ITU Telecom World to be held in Qatar should showcase this record-breaking success with the support of Ooredoo. By deploying our advanced LTE network in Qatar, we are truly laying the foundation for the future.”
Madam Huang Yuhong, deputy general manager of China Mobile Research Institute and secretary general of Global TD-LTE initiative (GTI) said: “This groundbreaking throughput is a milestone that boosts our efforts as we drive the commercialisation and globalisation of TD-LTE and TDD-FDD converged technology across the globe. In collaboration with Nokia Networks, our long-standing and trusted partner, we continue to exploit the immense capacity potential of TD-LTE.”
Zhang Qi, vice president of TD-LTE at Nokia Networks, said: “We just broke our own speed record which shows our capability to help operators address the ever-increasing demand for faster data download and upload speeds. TDD-FDD LTE not only delivers high uplink and downlink throughput, but also helps balancing the load between two networks, efficiently using the spectrum.”
