The mains can be a guide in the era of 5G

International Telecom giant AT&T recently presented the concept of so-called 5G Evolution. The operator is in full swing modernizing their own network around the world, introducing new developments and radically upgrade the existing transmission channels. One of the points of the concept paper on the relationship of the “fifth” generation is the implementation of the project AirGig, through which a signal with a speed of 1Gb/s will be to provide the inhabitants with the most remote corners of the planet. While infrastructure costs will be minimal.

In AT&T for over ten years, reflect on the technology that could provide a wider field of action for providing users with high-speed Internet. Years of work and research have led a team of engineers of the operator to the idea of data transmission using microwave waves. Frequency range of radio waves with a wavelength in free space from 1 to 10 mm corresponds to frequencies from 30 to 300 GHz. With the transmission of radio waves of this range can easily handle the antenna of small dimensions. However, the main task of which would be solved by the engineers is a strong attenuation of radio waves such that it allows the signal to overcome long distances.

Then one of the engineers AT&T in thought walking along one of the streets “one-storeyed” America looked up and saw a power line that delivers to every house, such people require electricity.

“Why not to do that and with the Internet signal? After all, this thing was no less necessary in the modern world,” thought the man in the white Bathrobe that says AT&T on the back.He came up with the idea to combine in one technology the power lines and millimeter waves. So in the minds of a team of engineers AT&T has a project AirGig by which the operator plans for several years to ensure that all rural citizens communication “fifth” generation.

The main idea of the project was that a small antenna for transmission of millimeter radio waves is placed on the power lines.

Work on the development of smaller transmitters was carried out for ten years. The result is a compact plastic device. The transmitter is installed on transmission towers, and then the signal is transmitted through electrical cable. Thus it is not transmitted through the wire along or near it.

In addition to the signal transmission antenna is used as the access point, distributing the signal in a particular range.

Imagine if such a device would be installed on each rod, you get a unified system for seamless connectivity with high speed data transmission. That is, the Gigabit Internet will be able to afford any resident of a remote village where there is electricity. At first glance, it resembles a plot for a science fiction utopia. In fact, all prosaic and quite feasible in practice.

About the beginning of work on the project provider was announced in September 2016. In fact, at the same time began and the first test of transmitters. In the first stage, on poles of power lines began to place a small cell-enabled C-RAN. The deployment of such a network allows the operator to prepare for the implementation of the project AirGig and lay the groundwork for deployment of the “fifth” generation worldwide.

AT&T say they have already received over two hundred applications for the use of the patent. The main advantage of the project is that electric networks have already been deployed in the vast number of localities on the planet. This significantly reduces infrastructure costs, as for the placement of antennas don't have to pull fiber-optic cable or set up communication towers. Therefore, the company sincerely believe that the project AirGig is the future of telecommunications. Thanks to him, broadband access will be possible where the Internet know only by hearsay.

Themselves of the antenna have small dimensions, and therefore their installation on poles also will not cause difficulties and high financial costs.

When the network is operational AirGig it is also proposed to depart from standard methods of operation, having refused from the widespread use of routers, switches and firewall, and opting for a software-oriented approach. plans to AT&T by 2020 to virtualize 75% of its network.

"We believe that the project AirGig has the potential to quickly bring connectivity to the Internet around the world. Now the project AirGig in combination with our software-defined network architecture has no equal in the transmission of data associated with mobile 4K video, virtual reality, telemedicine. With AirGig all this can be available as in the city, and remote rural areas", — said the Director for strategic development at AT&t, John Donovan.Telekom runs forward, and methods and technologies for the deployment of the network operators and IT companies sometimes staggering. But often the winner is not the one who was able to capture the imagination, and whose method combines simplicity and maximum efficiency. At first glance it looks AirGig such technology. However, there are many questions on the maintenance of such a network and fact find understanding the idea of deploying this technology from power grid companies and regulators.

At&T believe that they have a great offer for energy companies. Using the system will monitor the status of the transmission network and to measure the energy consumption. published
