Millimeter waves for future 5G networks

5G technology will respond to the demands of next-generation data transmission services, such as the mobile service in the cloud, games, social media applications and 3D immersion applications.

These require a massive capacity and higher data transmission rates than the current 4G networks are capable of sustaining and that the new 5G communication networks, currently under development, have to resolve.Within the framework of the European project of mmMAGIC 5GPPP research, researchers from IMDEA Networks, in collaboration with 18 partner organizations, have developed and designed a new mobile radio access technology for deployment in millimeter wave frequencies (mm-wave), which is a very promising solution for efficient delivery of high capacity data.

5G with a "ready to use" solution

Millimeter wave-based systems exploit frequencies above 10 GHz. Communications at such high frequencies pose unique challenges.On the one hand, mm-wave systems reach data speeds that are orders of magnitude higher than the current systems operating at lower frequencies.On the other hand, the links established by millimeter waves experience a great variability in the quality of the channel due to the high loss due to propagation and the unfavorable atmospheric absorption.fundamental that the mmMAGIC project has tried to answer is: How can we effectively overcome the challenges and benefit from the potential gains derived from the use of millimeter wave frequencies?

The mmMAGIC solution is a new concept of a radio system for mobile broadband communications aimed at operating in contiguous broad bands at millimeter wave frequencies.This new radio is a "ready-to-use" solution that, within the defined horizon by 2020, meets anticipated demands of the end user and network society traffic, in addition to addressing the specific challenges of the millimeter wave bands.

In particular, the new radio concept takes advantage of new channel models proposed within the framework of the project and provides a new antenna design with hybrid beam-forming capabilities.The design of this antenna addresses important practical limitations for actual deployment , such as the antenna size, cost and complexity. The validity of the design of this system has been corroborated through real-time experiments, which have shown its effectiveness under conditions real as for the channel and hardware used.

5G tests in Spain

5G networks will be fundamental in the future of communications and, therefore, the main companies in the technology sector are already working on their implementation. As we reported in Nobbot, Orange has marked a new milestone in Spain in the framework of the collaboration agreement signed with Ericsson for the development of 5G mobile connectivity.Both companies have made a pioneering experience to show the great features that 5G mobile connectivity will offer.

Millimeter waves for future 5G networks

For this, and for the first time in Spain, two tests have been carried out: the first, with a device that simulates the experience of a user at street level, in which speeds greater than 15 Gbps have been achieved; and a second, in a vehicle in mobility, in which it has been possible to watch a 4K video in real time (streaming) in motion, in an urban outdoor route. Both tests have been carried out using equipment real radio, all orchestrated by a 5G base station that has provided the necessary coverage to the test terminals.

a mobile of the size of a washing machine

Specifically, both companies have tested a terminal, similar to a domestic washing machine, with which they have surpassed, on board a van, maximum connection ranges of 17 Gbps through the 28 Ghz band, with uses up to 800 Mhz.

5G technology , the new generation of networks of Mobile broadband communications continues to be developed to solve the demand for mobile communications, services and applications expected; In the age of mobility, moving connectivity will become a priority need for users and professionals.

Internet of plants: a tomato knows as much about networks as you

The possibility of plant species communicating through complex networks, what some scientists have called the internet of plants , is an issue that has been discussed for a long time, at least 20 years.It was in 1997 when the scientist Suzanne Simard , from the University of British Columbia in Vancouver (Canada), published a study in the journal Nature on how Forest plants use complex systems where species exchange nutrients, send warning signals and relate to the environment. Although there is no scientific consensus, several investigations seem to support this hypothesis.If confirmed, as we read in a fascinating report by the Sinc Agency, the forests would act as huge structures that are articulated under the soil through a network in which factors invisible to the human eye interact and can determine the future of the climate.Understanding how it works is the challenge that even science faces. internet of plants and the wisdom of forests The premise of Suzanne Simard ...

New setbacks for conspiranoicos: radiofrequencies do not affect health

New evidence published by the Scientific Advisory Committee on Radio Frequency and Health (CCARS) in its 2016 Radio Frequency and Health Report indicates that there are no adverse health effects derived of exposure to radio frequencies emitted by mobile phone antennas or radio and television broadcasting.No evidence has been found on the danger in wireless systems (Wi-Fi) or airport scanners. The new 2016 Radio Frequency and Health Report collects, updates and analyzes the scientific evidence on the subject for the period between January 2013 and June 2016. radio frequencies are not dangerous According to the conclusions of the report " the critical analysis of the evidence supports that there are no technical or sanitary reasons that justify the arbitrary and discretionary imposition of more demanding exposure limits than those recommended by WHO-ICNIRP and the Union European ", while the application of more restrictive limits" would imply increasing the n...

GIF history: where they come from and where they are going

Funny, witty, curious... GIFs have already become a regular resource in social networks and messaging applications and have become part of our daily lives and jokes.It is an image format that has evolved significantly throughout its history and is experiencing a new awakening. In fact, to find its origins, we must go back more than twenty years ago .A moment in which they had little to do with what we know today and an evolution that we could not stop review.So let's find out where they come from and try to catch a glimpse of where they are going. What is a GIF The word GIF responds to the acronym of Graphics Interchange Format , or what is the same, graphic exchange format.A term for the graphic format used in the network for both static images and animations.In more concrete terms, it supports 8 bits per pixel and allows you to display images with up to 256 colors simultaneously-limited by a palette of 16 million-. This particularity makes it a perfect ally of infogr...

Amazon Prime Video arrives in Spain: this is all you need to know

What we know and what we suspect in the new Facebook algorithm change

"In my time, we read the newspaper in Facebook ".By 2020, nostalgia has taken over billions of people.In its memory, 2018, when Facebook stopped being Facebook to become Facebook again.Paraiso of engagement for brands and media, land paid for clickbaits and fake news, the social network of Mark Zuckerberg has given a rudder to his algorithm. He wants to return to his origins .And this is what will happen. Related If something goes well, to change it.40.653 million dollars entered in 2017.More than 2.100 million active users per month, a quarter of the world's population.But Zuckerberg is not one of those, of which they are.Want a Facebook with more social connections between people and less presence of brands and media .And what do your users want? Nearly two-thirds of American adults consume news on social networks.More than half do so on their Facebook walls.Pew Research Center data points to a clear trend: Facebook is becoming a media platform.54% of Facebook u...

No kidding: selfitis exists and can be a problem

Sometimes one thinks that social networks were created to share photos of faces putting on little bones and images of dishes overflowing with appetizing foods or, better, of faces putting little bones in front of plates overflowing with appetizing foods in the same shot.is to see faces, faces, faces...all of them smiling, as if looking at the smartphone mirror was the height of happiness.And it does not seem that there are so many beautiful and happy people, or maybe yes, that you go Namely.What envy. Well, what we're going to do: Janarthanan Balakrishnan psychologists from the Thiagarajar School of Management in India; and Mark D.Griffiths, of the Nottingham Trent University, in the United Kingdom, have published an article in the International Journal of Mental Health and Addiction entitled 'A study on' Selfitis', which names this mania of going around the world taking pictures of oneself, as if beyond our curls the world had been destroyed by that meteorite th...

Twitter shows the best of ourselves (it wasn't always going to be the worst)

In the era of social networks, accustomed to interact daily with Facebook, Twitter, Instagram, Google or WhatsApp, we forget that these tools are phenomenal in the History of Humanity capable of mobilize hundreds of thousands of people in very different geographical locations in a matter of hours or even minutes. Already in the past, Twitter has asserted its more social dimension to mobilize people, companies or organizations and also, from a broader perspective, feelings of solidarity and support or also of rejection and repulses towards causes with an important mediatic impact.Recently, Twitter was once again the engine of solidarity after Dortmund's explosions as the Borussia Dortmund team bus passed on its way to the local stadium on the occasion of the Champions League match between the Borussia and the Monaco. These explosions did not have the devastating effect that they could have caused , so that everything remained in a major social commotion at international lev...

Most apps for children violate your privacy

Do you know if apps with which children enjoy their safety? A team of researchers from the International Computer Science Institute (ICSI) of the University of Berkeley has studied compliance with the Online Privacy Protection Act (COPPA) in these mobile applications for the little ones, through a scalable dynamic analysis that allows the automatic evaluation of privacy behaviors of Android apps. After studying 5,855 applications aimed at children, the research concludes that most of these apps, 57%, violate the privacy of their users mainly due to the use of data by third parties. apps for children and privacy Although many apps offer options in their configuration to respect the federal law that protects minors in the United States, by disabling tracking, their results suggest that a majority of applications either do not use these options or propagate them in wrong way. In addition, researchers believe that 19% of apps for children send user IDs to third parties to show ...

Are social networks damaging democracy?

The revelations according to which Russian agents inserted ads on Facebook that tried to influence the 2016 US elections raise a disturbing question: is Facebook bad for democracy? As an expert in the social and political repercussions of technology, I think that the problem is not exclusively from Facebook, but that it is much broader: Social networks are weakening some of the conditions that have historically enabled the existence of national states democratic. I understand that it is a dramatic statement, and I do not expect anyone to believe it immediately, but considering that almost half of all potential voters received false news promoted by the Russians in Facebook is an argument that must be debated. Associate Professor of Philosophy, Director of Center for Professional and Applied Ethics, University of North Carolina-Charlotte How we create a shared reality Let's start with two concepts: the "imagined community" and the "bubble filter". ...

This is how visual challenges star in some of the most viral content

Constantly, we all receive in our mail, our WhatsApp or our Facebook account, games that try to test our ingenuity, imagination or visual skill.There are a thousand types, more fun or darker.But they have one thing in common: we cannot avoid trying them and see if we are able to solve them .This is how the visual challenges star in some of the most viral content of the network. Visual challenges, why are we crazy? The visual challenges are games.So, they attend to this playful and fun part that people have no choice but to feed from time to time.They are pure and hard entertainment, with no more pretensions, and that desire to Having fun represents one of the main features that are sought when surfing the Internet . Another of the qualities for which they succeed is because they challenge the mind directly.Human beings love that feeling of feeling a little troubled, somewhat lost, but convinced that there is a solution to that enigma to which, sooner or later, it will come.Rathe...
