The great ambition of the networked society is to connect everything, everywhere, all the time. But the ideal of seamless communications poses fundamental challenges to legacy networks that the new 5G communication networks currently under development need to solve. One of such challenges is supporting the significant growth of traffic demands. Next generation services such as mobile cloud service, gaming, social-networking applications and 3D immersive applications require massive capacity and higher data rates than current 4G networks are unable to sustain. In the framework of the mmMAGIC2 5GPPP European research project, researchers at IMDEA Networks3 in collaboration with 18 partner organizations, have developed and designed a new mobile radio access technology for deployment in mm-wave frequencies, a highly promising candidate solution for efficient high capacity data delivery.

Millimeter-wave (mm-wave) systems exploit frequencies above 10 GHz. Communications at such high frequencies pose unique challenges. On the one hand, mm-wave systems achieve data rates that are orders of magnitude higher than current systems operating at lower frequencies. On the other hand, mm-wave links experience high variability in channel quality due to high propagation loss and unfavorable atmospheric absorption. Hence, the fundamental question the mmMAGIC project aimed to answer is: how can we efficiently overcome the challenges and benefit from the potential gains arising from the use of mm-wave frequencies? The mmMAGIC solution is a new radio system concept for mobile broadband communications targeting operation in wide-contiguous bands in mm-wave frequencies. The new radio is a ready-to-use solution that meets the anticipated end-user and traffic demands of the networked society in the 2020 time-frame and addresses the specific challenges of mm-wave bands.

In particular, the new radio concept takes advantage of novel channel models proposed in the framework of the project and provides a new antenna design with hybrid beamforming capabilities. The antenna design addresses important practical constraints for real deployment, such as antenna size, cost and complexity. The validity of the system design has been corroborated by hardware-in-the-loop experiments, showing its effectiveness under real channel conditions and with actual hardware. Within the mmMAGIC project, conceptual enablers that will compose the new mm-wave 5G architecture have been identified and assessed. In addition to the enablers, radio access network and transport functionalities for network integration of mm-wave radio access technology have been introduced. Within the former category, a predictive beam-steering approach has been proposed to improve performance of mm-wave links and relieve part of the time burden caused by beam training procedures. The approach exploits history information about the users’ movement patterns and can also be employed for accurate indoor localization systems.

mmMAGIC was an industry-driven project, bringing together major infrastructure vendors (Samsung, Ericsson, Alcatel-Lucent, Huawei, Intel, Nokia), major European operators (Orange, Telefonica), leading research institutes and universities (Fraunhofer HHI, CEA LETI, IMDEA Networks, Universities Aalto, Bristol, Chalmers and Dresden), measurement equipment vendors (Keysight Technologies, Rohde & Schwarz) and one SME (Qamcom). The project operated from June 2015 to June 2017.

Space X’s Satellite Broadband Network Has a Name: Starlink

I actually may be interest in this if they pull it off.

1 of the big problems about satellite internet is they have so few satellites up there and your signal fights between everyone else’s signal and that signal goes up and down depending on the any given moment on where the satellite is.

4,000 satellites would mean that I have more to pull from, perhaps better range of signal, and less fighting to get through.

The question now is how quickly will they get all those (4,425) satellites in orbit. Their competition takes years to launch even 1 into orbit. Can they really streamline the process and get this off the ground, is my question.

Expanded broadband can help combat rural flight

“I have a feeling we’re not in Kansas anymore” is one of the most iconic lines in movie history. But for rural parts of the Sunflower State, like my hometown of Parsons, this quote has taken on a new, more ominous meaning.

In recent years, growing numbers of rural Kansans have been leaving home, and this trend appears to be accelerating. A Wichita State University study projects that over the next 50 years, 62 out of Kansas’ 105 counties will lose more than a quarter of their residents. The brain drain flowing out of the state’s rural communities is real, growing, and troubling. I know the value of growing up in a rural community and want to ensure future generations will be able to have that same experience. That’s why, as Federal Communications Commission chairman, I’ve made it my No.

1 priority to close the digital divide — that is, the gap between those who have access to high-speed Internet, or “broadband,” and those who don’t. In my view, every American deserves digital opportunity.

Broadband’s power to conquer distance and overcome isolation holds special promise for rural America. It empowers small businesses to reach new customers and markets. It enables educational options through distance learning. It extends health care through telemedicine, which makes it possible to be treated remotely by a specialist even if you live hours from the nearest hospital. And it expands farm productivity through precision agriculture and the like

Expanding Internet access to all rural communities alone won’t reverse population losses. But broadband-enabled technologies can be a big equalizer for rural communities. It can raise the standard of living, opening doors of opportunity that were previously closed, and create a sense of hope about the future.

The hard truth is that rural America has a lot of catching up to do. In rural America, 28 percent of households lack access to high-speed, fixed service, compared to 2 percent in urban centers. In Kansas, more than 200,000 people in rural areas aren’t able to get high-speed home broadband. Bridging the digital divide in rural America is challenging. That’s why the FCC is using every tool in our toolkit to close the gap.

Through our Mobility Fund, a successful public-private partnership, the FCC will invest $4.53 billion over the next decade to bring 4G LTE service to rural Americans who don’t have it today. Additionally, we’ve approved $2 billion through our Connect America Fund to boost fixed broadband in currently unserved locations. The FCC has also started several initiatives to get rid of bureaucratic red tape and barriers to network investment. This will make it easier to install infrastructure needed for wired and wireless broadband.

And to expand access and competition, we’re getting creative. For example, the FCC approved a plan this June allowing a company to use hundreds of satellites in low-Earth orbit to provide high-speed broadband. This could be promising for those living in hard-to-serve areas. Some say we can’t afford to bring high-speed connectivity to places like rural Kansas. I say we can’t afford not to. By closing the digital divide, I’m confident more Kansans will build their futures in the communities where they grew up.

Perhaps future generations too will find that there’s no place like home.
