The blazing light will help the wireless data transfer rate go beyond optical fiber

If put into practical use, this will be the key to speed Internet access super fast to a lot of people.

According to Engadget, optical fiber has a very fast speed but there is still a limit: you will still need ... wires to transmit data, making this transmission difficult in certain areas, as well. High cost. Consequently, scientists have over the years studied a way to overcome this limitation, eliminating "wires" while ensuring high, even higher transmission rates.

Recently, they have discovered a way to "break" the paths of photons (light molecules), making it capable of transmitting more data at each transmission, and not being affected. by the turbulence of the air. Specifically, if you project the light through a special hologram, light will be able to achieve an " optical angular momentum" that will allow it to carry more information than With binary codes 1 and 0 normally, as long as the phase and the light intensity are correct, the beam will be able to carry data over long distances.

There are still limits to the transmission of light.

The team has successfully tested this beam for a distance of 1.6 km in Germany to ensure that the beam can be used in urban environments - where tall buildings, streams The air is often extremely turbulent.

Of course, this method still needs to be studied much before being brought into practical use. For example, how can a light stream carry data to a large number of users, or is the flow of data affected by rain and snow?

Anyway, this is a promising method. There are still limits to the transmission of light (such as being unable to transmit in indoor space for a variety of reasons), but this will be a potential direction to the system. next generation wireless network.

In the not so distant future, instead of relying on wires at home or in the office to access the Internet at gigabit speeds, service providers will be able to use wireless transmitters that use light They are bright in most of their networks, and they only use strings when they are really needed.
