New, Contiguous Spectrum at 5 Gigahertz Will Drive Transition to Gigabit Wi-Fi, Encourage Economic Growth

-- New report finds that policymakers must act to prevent “broadband bottlenecks” and ensure adequate capacity for HD Video and other next generation apps --


Today’s Internet, especially with wireless access, allows us to connect easily over social media, have instant access to information, and increasingly use live, and mostly real-time, video.  It’s been an amazing transformation over the past two decades, but – believe it or not – it pales in comparison with the promise around the corner, a promise enabled by Gigabit Wi-Fi.  A new study by Plum Consulting predicts that Europe could reap more than €16.3 billion in future economic benefit if we take steps to facilitate the transition now.


Tomorrow, Internet video will be in HD, all the time, with no delay.  And the applications will go well beyond talking to your friends, parents, or grandparents on your smartphone or tablet.  HD wireless video will be in your child’s classroom.  It will be in hospitals, in apartment buildings, and manufacturing facilities, at train stations, in airports and on the streets.  The possibilities and applications are endless, and it will dramatically change the way people connect, collaborate, and live.


To speed this next wave of technological innovation, governments need to make smart choices now.  Put simply, there are bottlenecks with today’s Wi-Fi that make the promise of HD video all the time, just that, a promise.


This is especially important in Europe, where the goal – as laid out in the European Digital Agenda – is to have 50% of households having access to Internet at 100 Mbps by 2020.


Governments need to make new, contiguous spectrum at 5 gigahertz available to make Gigabit Wi-Fi a reality.  That’s the major conclusion of the  new report by Plum Consulting entitled “Future-proofing Wi-Fi: The Case for More Spectrum.”


Specifically, the report finds that:

  • There’s simply not adequate contiguous Wi-Fi spectrum today to enable the technologies and applications that are coming around the corner.  We all connect to Wi-Fi in our homes, coffee shops, and airports.  Businesses use Wi-Fi for their internal networks and manufacturing lines.  Wi-Fi has become a dominant form of internet access -- - by 2016, 60% of total Internet traffic will begin or end on Wi-Fi. So it’s critical to take action now to prevent broadband bottlenecks down the road.

  • 5th generation Wi-Fi – known as 802.11ac -- can deliver much faster speeds and capacity and avoid these bottlenecks.  For instance, it can deliver much more robust networking in enterprise like hospital, schools, or factories.

  • 802.11ac requires larger contiguous bands of spectrum to operate more efficiently and effectively.


Therefore, the Plum report concludes that the European Commission should direct CEPT (the European Conference of Postal and Telecommunications Administrations) to launch a study to assess whether, and under what conditions Wi-Fi would be able to share the spectrum with incumbent users, and how to make this a reality.  If the process to allow Wi-Fi to use more spectrum is not begun now, then we will begin to see demand outstripping capacity in certain scenarios down the line. For example, at major transport hubs we are likely to see capacity and speed constrained by 2016.


There’s not just a technological imperative to do this, but an economic one as well.  For Europe alone, the Plum report conservatively estimates that economic benefit from providing additional spectrum for Gigabit Wi-Fi for Europe is €16.3 billion, or almost $22 billion.  This includes €12.3 billion in gains from improved quality of service from contested environments and €4 billion from increased mobile offload capabilities. So this will drive economic growth as well.


Here’s the bottom line:  The promise of the next-generation is enormous.  But putting in place a new contiguous block of spectrum will take time.  So it’s imperative that governments act now so that the foundation for next-generation applications and wireless HD video will be in place and the promise of tomorrow’s Internet can be fully realized.

WebRTC is about the data channel as much as about video and audio conferencing. However, basically all commercial WebRTC applications have been built with a focus on audio and video. The handling of “data” has been limited to text chat and file download – all other data sharing seems to end with screensharing. What is holding back a more intensive use of peer-to-peer data? In her session at @ThingsExpo, Dr Silvia Pfeiffer, WebRTC Applications Team Lead at National ICT Australia, will look at different existing uses of peer-to-peer data sharing and how it can become useful in a live session to...

Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...
WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.
WebRTC converts the entire network into a ubiquitous communications cloud thereby connecting anytime, anywhere through any point. In his session at WebRTC Summit,, Mark Castleman, EIR at Bell Labs and Head of Future X Labs, will discuss how the transformational nature of communications is achieved through the democratizing force of WebRTC. WebRTC is doing for voice what HTML did for web content.
The broad selection of hardware, the rapid evolution of operating systems and the time-to-market for mobile apps has been so rapid that new challenges for developers and engineers arise every day.

When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings. Until now clean technology was offered piecemeal and led with point solutions that require significant systems integration to orchestrate and deploy. There didn't exist a 'top down' approach that can manage and monitor the way a Smart Building actually breathes - immediately flagging overheating in a closet or over cooling in unoccupied ho...
