The first step for telephone networks and ultrafast wifi

Demand better connections and networks in society should lead ultraconectada wireless networks capable of moving massive amounts of data. A team of engineers from Brown University (USA) have succeeded in developing a key component for terahertz wireless networks, which would be a hundred times faster than today.

Despite the huge leap in this area in the past two decades, working on terahertz frequencies allow the future capacity data transmission that has little to do with the present. Imagine percent networks multiply the capacity of telephone networks 4G, 5G Wireless imminent or around us.

All that goes through a series of advances that will take time, but the first steps begin to occur in different parts of the world. A key component to the future of ultrafast internet phones and tablets just see the light in the laboratories of Brown University in Providence, Rhode Island (United States).

Engineers have developed a key player in this area to ensure that it is the first multiplexing system of terahertz waves. “A multiplexer is a device for combining many signals on one channel and a demultiplexer separates the signals. All communication systems, from mobile, the wireless radio or somehow used a similar system, as through the fiber travel thousands of calls and dozens of TV channels, for example.

Where there terahertz frequency networks a system that can do the same will also be required and what we have developed is the first multiplexer that can work at these levels, “explains told Efe Future Daniel Mittleman, a professor of engineering in Telecommunications Brown University and lead author of the paper describing the discovery in the journal Nature Photonics .

How it works

The multiplexer in which they have worked Mittelman and colleagues has an antenna consists of two parallel metal plates so as to serve as a guide for the wave. One of the plates has a small slit. The high frequency wave travels over the waveguide and part of the radiation escapes through the crack and does so in a different angle depending on the frequency.

That means that if 10 different frequencies, that is, different signaling pathway by each will get a different angle, which means that we are separating these signals have traveled through a single channel. “A determining factor is that most of the solid materials tend to absorb the terahertz waves, but the advantage of our design is that only the signal propagates through the air or through the space between the two plates is air.

So in this case it works when other multiplexers had failed to deal with terahertz frequencies, “said Mittleman.

A minimum of 10 years

But unfortunately all the elements of a high-speed network a reality is something that will take time. For starters, the multiplexer for terahertz been proven to work, but no longer a project to some rudimentary point, a proof of concept that opens doors, but to which we have a long way to go. Future Mittleman said to EFE that “many of the components of these networks do not even exist yet. And those that do exist are bulky and expensive to become small-scale components that may occur in string.

I’m not very good at making predictions for the future, but I would say that this will not become a reality for another 10 years or even 15. But clearly the need for higher bandwidth will become increasingly acute. 4G networks and access points wifi soon be saturated and 5G networks will not solve that problem for long. So terahertz technology will be very necessary. And obviously we must develop it, “he concludes.

In its next stage of research, researchers Brown will hand his colleagues at Japan’s Osaka University, which will test the device on a network prototype terahertz being built. A step in a challenge in the current field of telecommunications.
