Deutsche Telekom and Huawei break gigabit mobile speed record

Deutsche Telekom and Chinese electronics group Huawei have breached the one-gigabit speed barrier for mobile data transfers in the LTE network. During a live demonstration in Berlin, they succeeded in transmitting data with 1.22Gbit/s via mobile radio.
In 2010, DT began paving the way to the gigabit society. Since then, fixed-network customers in particular have increasingly benefited from fast connection speeds. Together with Huawei, Deutsche Telekom has now achieved a breakthrough in Berlin for its mobile customers as well.
"User behaviour is evolving rapidly on the way to a gigabit society," said Claudia Nemat, Deutsche Telekom board member. “That's why fast internet access can't be limited to just fixed lines and fibre optics. Our customers also want the highest possible speeds for maximum comfort on the go as well. As you can see, our network delivers. We are ahead of our time and ahead of the competition.”
The more high-quality video people retrieve on their smartphones, the more data have to be transported through the mobile networks. The same applies to live streams and detail-rich games. These constantly increasing demands are driving the evolution of the LTE wireless technology forwards on the way to 5G.
Deutsche Telekom and Huawei used the latest evolutionary step of this technology – LTE Advanced Pro – with a conventional mobile base station, which was bundled with a small cell; the data traffic flowed over five carrier frequencies instead of just one. This required one thing above all from both the transmitter station and the receiving devices: they have to support 4x4 MIMO (multiple input, multiple output) technology. If all these components are used, individual users can enjoy peak speeds of more than 1Gbit/s. Wireless capacities in the equipped cells are also improved for all users.
"Huawei strongly believes in the best user experience as the foundation for the successful future of Deutsche Telekom," said Lin Baifeng, president of Huawei’s Deutsche Telekom account. “Together we innovate for the advanced wireless technology and Huawei is happy to support Deutsche Telekom to prove the benefits of the latest evolutionary step of this technology, LTE Advanced Pro, in real field application.”
The current move by Deutsche Telekom and Huawei represents the next step in a long-term collaboration in the development of mobile communications and the roll-out of Germany's fastest LTE network. In an earlier test last year, the two companies bundled three carrier frequencies in Berlin, reaching speeds of over 340Mbit/s. They have now beaten this record by far, taking a step towards creating the gigabit society.
