The new wireless network will transmit data at speeds of 100Gb / s

new wireless networkThe idea belongs to the scientists from the German Karlsruhe Institute of Technology.

Researchers from the German Karlsruhe Institute of Technology (KIT) have created a wireless network, the data rate which comes to one hundred gigabits per second. An article about the experiment was published in the journal Nature Photonics; its summary can be read at KIT.

Signal transmitter built by scientists in the network is setup with two laser emitters. The electrical signal generated in the installation with help the photodiode and it is the difference in frequency between two laser signals (237.5 GHz).

At the receiver the signal is transmitted through a conventional serial antenna. The receiver uses the integrated circuit based high electron mobility transistor (HEMT- transistors ), so that it can accept signals ranging from 200 to 280 GHz.

Speed ??network, established in Karlsruhe, has been deployed in the laboratory. The data it managed to convey only a distance of twenty meters, as at these frequencies the receiver and transmitter must be in line of sight.

Earlier, in the spring of 2013, the same researchers were able to transmit data over a distance one km at a speed of forty gigabit per second. The details of the experiment can be found here.

The massive network of Wi-Fi, describes the protocol IEEE 802.11, typically operate in the range of 2.4-5 GHz. The maximum data rate in them is 54 megabits per second, although proposed in 2009 WiGig standard provides a theoretical speed of up to 7 gigabits per second at a frequency of 60 GHz.
