Set a record speed of data transmission "over the air"

German researchers have set a record, deploying a wireless network with a data transfer rate of 40 gigabits per second kilometer radius. This result was achieved by scientists from the Fraunhofer Institute (FIIS) and the Karlsruhe Institute of Technology (KIT).
The opening will make high speed Internet available in remote regions, for example in rural areas, and reduce the installation costs of fiber optic networks. The project Millilink scientists have created a small radioperedachi of size 4x1,5 mm, it operates in the range of 240 GHz.





In the chip involved the semiconductor technology, which was developed in FIIS. It is the increase of circuits on semiconductors of group III–V including transistors with high electron mobility.
Scientists claim that the transmission of 40 Gbit/s "by air" is just the beginning. "Improving spectral efficiency by using more complex modulation formats or combining multiple channels, such as multiplexing, will provide an opportunity to achieve even higher speeds," says engineer Jochen Ansen of KIT.





Technology created by the Germans, hardly will soon see the future. It is more likely that the era of 5G networks come faster, by 2020.
