Couple of talks by NTT Docomo on 5G and Beyond (pre-6G)

The Japanese operator, NTT Docomo is a very bold MNO. Not only do they do interesting research but they are very open about what they have been doing and share it publicly. For example, last month they announced development of a safe, blade-free drone propelled by Ultrasonic Vibrations (tweet). This was just amazing as it has a potential to use drones in many new areas where the conventional drones are deemed too dangerous. This is why I was very pleased to see couple of talks by Docomo available online.

The first one is by Takehiro Nakamura, SVP and General Manager of the 5G Laboratories in NTT DOCOMO, Inc. at the 6G Summit in Finland. Slides available here. Video embedded below




The next one is by Seizo Onoe, Chief Technology Architect, NTT DOCOMO, INC. and President, DOCOMO Technology, Inc. from Brooklyn 5G Summit. Unfortunately the slides are not shared but the video is worth a watch below.

China Telecom: An examination of the current industrial trends and an outlook of 6G

Last month I posted about the slides and videos from 6G Wireless Summit. Some of the videos were added later on. The presentation by Dr. Qi Bi, President of China Telecom Technology Innovation Center and the CTO of China Telecom Research Institute, was not shared but the video of the talk is available and it is quite insightful.

Of the many gems from the talk, I wanted to highlight couple of things. One was the ARPU, that Dr. Bi pointed out has remained the same, regardless of the technology. The other being 5G performance targets, some can be achieved, some are achievable at a price and some are just not achievable. This should be taken into account while designing 6G.

Slides and Videos from the 1st 6G Wireless Summit - March 2019

The first 6G wireless summit was held in Levi ski resort, in beautiful Lapland. According to the report by University of Oulu, 287 participants from 28 different countries spanning all inhabited continents took part. According to the report:

At the Summit, the participants’ were asked to project themselves into the world in 2030, potentially very different from today. As professor Matti Latva-aho, the director of 6G Flagship at the University of Oulu, and the driving force behind the vision of global 6G, puts it: ”The vision for 2030 is that our society is data-driven, enabled by near-instant, unlimited connectivity. We will be facing a growing and ageing population, demands for increased productivity and the need to connect the billions who are not currently connected. We challenged all of the conference attendants, pressing them to consider this future world beyond 5G and the most essential aspects of 6G research -- a decade in advance.”

Peter Vetter, Head of the Access Research at Nokia Bell Labs and a Bell Labs Fellow, took on Latva-aho’s vision for the future. Vetter says that in the future, the network needs to be thought of as a platform that creates network instances for specific environments. Specialized uses can be easily imagined including hospitals, elderly care, traffic and power plants. At the heart of it all is enhancing the human condition, Vetter says. “6G is still ten years and longer out, and I think that this is a consensus among the 6G Summit participants. However, it is time to start the research right now, because it takes 10-20 years before a new innovation sees a commercial launch,” Vetter says.

For wireless revolution to happen, there needs to be a revolutionary communication technology, a revolutionary application of that technology and a whole ecosystem for continued innovation, says Dr. Wen Tong, Head of Wireless Research and Head of Communications Technologies Laboratories at Huawei. “Wireless as a field has plenty of room for innovation. We need a young generation of researchers and an environment that will sustain continued innovation. This is very important, as without the young generation of research leaders the sustainability of the ecosystem will become problematic,” Dr. Tong explains.

Takehiro Nakamura, SVP and General Manager of the 5G Laboratories in NTT DoCoMo brought up the requirements for many future use cases, such as low latency, reliability, massive connectivity etc. and made a point that most of these will be met with 5G. “Then, there will be new combinations of extreme requirements for specific use cases. We need to provide extreme high reliability for a guaranteed quality of service for industry, peak data rates of over 100 Gbps, gigabyte-rate coverage everywhere, and to have everything run at extreme low energy consumption and cost,” Nakamura says. As Nakamura sees it, the future will have high-quality, real-time VR and AR. Massive IoT for anything and anywhere, like satellites in space. Broadband for flying mobility, which will need high coverage and high reliability.

Qi Bi, President of China Telecom Technology Innovation Center and CTO of China Telecom Research Institute thinks that 6G could be a turning point and a real revolution from 5G also in other terms besides technological. Even if we don’t yet know what 6G will be, it is going to be based on past generations and some traits will be there, Dr. Bi says. As far as gauging 6G research today, Dr. Bi says that the Summit was a great event for percolating a lot of ideas.

Some of the hot topics in 5G and in 6G are machine learning and artificial intelligence. Head of Ericsson Research Magnus Frodigh is a big believer in the coming 5G evolution. As networks are Ericsson’s strong point, Frodigh says it will be very interesting to see what distributed AI is going to bring to the game.

Some interesting April Fools' Day 2019 Technology Jokes

This year April Fools' Day wasn't as fun as the last one, even though it was on Monday. Many tech companies that make effort didn't make one this year. In fact Microsoft went even further and banned any public facing April Fools' pranks. Anyway, here are some of the jokes that I found interesting.

Parallel Wireless 7G Vision
This one was important for me as it features me (Yay!) and also enhanced my video editing skills. Grateful to CW (Cambridge Wireless) for being part of it too.

Parallel Wireless would today like to announces our 7G Vision (#7GVision) - https://t.co/Ffj63NX5F3 - Cambridge Wireless (@cambwireless) will form new Special Interest Group (SIG) to support the 7G Vision with @zahidtg joining the team too. pic.twitter.com/puz3cOoOGn

— Parallel Wireless (@Parallel_tw) April 1, 2019

Video is slightly long but funny hopefully



In short, the focus for the next few years will be do design a 7G logo that can explain the vision and connect with people. Did I mention 7GPPPPP?

"#7G Public Private Political Polling Partnership (7GPPPPP) with many different companies and organizations has also been formed to work on this vision."

Well played @Parallel_tw @cambwireless! ;)#AprilFools https://t.co/Lhxqk2Eifq

Google Sssnakes on a map

Google temporarily added a version of the classic game Snakes into its Google Maps app for April Fools’ Day this year.

The company says that the game is rolling out now to iOS and Android users globally today, and that it’ll remain on the app for the rest of the week. It also launched a standalone site to play the game if you don’t have the app.

Jabra Ear bud(dy)

World’s first shared headphone - engineered for shared music moments. The website says:

The headphones come with an ultra-light headband that extends seamlessly to accommodate the perfect fit for every pair of buddies, so you’ll never have to enjoy another music moment alone. The Jabra Earbud(dy)™ comes with a unique Buddy mode that promises a shared music experience that is tailored to suit each person’s preferences. Fans of voice command will be thrilled to know that with just one touch, the Jabra Earbud(dy)™ can connect to dual voice assistant.


T-Mobile Phone BoothE

T-Mobile USA and their CEO John Legere never disappoints. They always come up with something interesting. Here is a video of the prank


From MacRumours:

T-Mobile is again fighting one of the so-called pain points of the wireless industry with the launch of the Phone BoothE, a completely sound-proof and high-tech phone booth that lets T-Mobile customers escape from noisy areas to make their phone calls. Inside the Phone BoothE you can charge your devices, connect to a smart screen called "Magenta Pages" to mirror your smartphone display, and adjust the lighting to take great selfies.

In regards to the name, T-Mobile is taking a shot at AT&T's misleading 5GE label: "The Phone BoothE is an evolution towards the new world of mobility. Like many in the tech and wireless industry today, we decided that by adding an "E" to the name, you would know it's a real technology evolution." 

Although this is an April Fools' Day joke, T-Mobile has actually built the Phone BoothE and deployed them in select locations around New York City, Seattle, and Washington, DC, where anyone will be able to use them. The company on Monday also revealed the T-Mobile Phone BoothE Mobile EditionE, which is more in line with a straightforward April Fools' Day hoax, as it's "literally a magenta cardboard box with a hole in it." 

While the actual site disappeared after April 1, the archived version can be seen here.

Beyond-5G and 6G at #MWC19

MWC is huge and there is absolutely no way that I even managed to cover 1% of the floor, even though I spend half a day, every day looking at the demos and talking to companies. I came across just a couple of companies looking at post 5G research. One was Mehdi Bennis, from University of Oulu and a good friend of this blog and the other one was Interdigital, which has featured heavily on 3G4G blogs too.

From the standards point of view, I am only aware of ITU 'Network 2030' (FG NET-2030) that is looking at how future network architectures, requirements, use cases, and capabilities of the networks will change by 2030 and beyond. I blogged about it here.

It's too early to call anything as 6G because we don't even realise the ways in which 5G will change the world and the limitations that will feed into the requirements of IMT-2030 (just guessing the probable name).

So here is the first video from Mehdi Bennis.

Thank you all for visiting #6GFlagship at #MWC19 Finland Pavilion - Looking forward collaborating with you who we met!

I also caught up with Interdigital and I got a very detailed video on their vision of what comes beyond 5G



Would love to know what else did I miss on 6G and Beyond-5G at MWC 2019.

ITU 'Network 2030': Initiative to support Emerging Technologies and Innovation looking beyond 5G advances

Source: ITU

As per this recent ITU Press Release:

The International Telecommunication Union, the United Nations specialized agency for information and communication technology (ICT), has launched a new research initiative to identify emerging and future ICT sector network demands, beyond 2030 and the advances expected of IMT-2020 (5G) systems. This work will be carried out by the newly established ITU Focus Group on Technologies for Network 2030, which is open to all interested parties.

The ITU focus group aims to guide the global ICT community in developing a "Network 2030" vision for future ICTs. This will include new concepts, new architecture, new protocols – and new solutions – that are fully backward compatible, so as to support both existing and new applications.

"The work of the ITU Focus Group on Technologies for 'Network 2030' will provide network system experts around the globe with a very valuable international reference point from which to guide the innovation required to support ICT use cases through 2030 and beyond," said ITU Secretary-General Houlin Zhao.

These ICT use cases will span new media such as hologrammes, a new generation of augmented and virtual reality applications, and high-precision communications for 'tactile' and 'haptic' applications in need of processing a very high volume of data in near real-time – extremely high throughput and low latency.   

Emphasizing this need, the focus group's chairman, Huawei's Richard Li, said, "This Focus Group will look at new media, new services and new architectures. Holographic type communications will have a big part to play in industry, agriculture, education, entertainment – and in many other fields. Supporting such capabilities will call for very high throughput in the range of hundreds of gigabits per second or even higher."

The ITU Focus Group on Technologies for 'Network 2030' is co-chaired by Verizon's Mehmet Toy, Rostelecom's Alexey Borodin, China Telecom's Yuan Zhang, Yutaka Miyake from KDDI Research, and is coordinated through ITU's Telecommunication Standardization Sector – which works with ITU's 193 Member States and more than 800 industry and academic members to establish international standards for emerging ICT innovations.

The ITU focus group reports to and will inform a new phase of work of the ITU standardization expert group for 'Future Networks' – Study Group 13. It will also strengthen and leverage collaborative relationships with and among other standards development organizations including: The European Telecommunications Standards Institute (ETSI), the Association for Computing Machinery's Special Interest Group on Data Communications (ACM SIGCOMM), and the Institute of Electrical and Electronics Engineers' Communications Society (IEEE ComSoc).

According to the Focus Group page:

The FG NET-2030, as a platform to study and advance international networking technologies, will investigate the future network architecture, requirements, use cases, and capabilities of the networks for the year 2030 and beyond. 

The objectives include: 

• To study, review and survey existing technologies, platforms, and standards for identifying the gaps and challenges towards Network 2030, which are not supported by the existing and near future networks like 5G/IMT-2020.
• To formulate all aspects of Network 2030, including vision, requirements, architecture, novel use cases, evaluation methodology, and so forth.
• To provide guidelines for standardization roadmap.
• To establish liaisons and relationships with other SDOs.

An ITU interview with Dr. Richard Li, Huawei, Chairman of the ITU-T FG on Network 2030 is available on YouTube here.

A recent presentation by Dr. Richard Li on this topic is embedded below:

Towards a New Internet for the Year 2030 and Beyond from 3G4G

First Workshop on Network 2030 will be held in New York City, United States on 2 October 2018. Details here.

100 Gbps wireless transmission using Orbital Angular Momentum (OAM) multiplexing

From a press release by NTT Group:

Nippon Telegraph and Telephone Corporation (NTT, Head Office: Chiyoda-ku, Tokyo, President and CEO: Hiroo Unoura) has successfully demonstrated for the first time in the world 100 Gbps wireless transmission using a new principle — Orbital Angular Momentum (OAM) multiplexing — with the aim of achieving terabit-class wireless transmission to support demand for wireless communications in the 2030s. It was shown in a laboratory environment that dramatic leaps in transmission capacity could be achieved by an NTT devised system that mounts data signals on the electromagnetic waves generated by this new principle of OAM multiplexing in combination with widely used Multiple-Input Multiple-Output (MIMO) technology. The results of this experiment revealed the possibility of applying this principle to large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G scheduled for launch. They are expected to contribute to the development of innovative wireless communications technologies for next-generation of 5G systems such as connected cars, virtual-reality/augmented-reality (VR/AR), high-definition video transmission, and remote medicine.


NTT is to present these results at Wireless Technology Park 2018 (WTP2018) to be held on May 23 – 25 and at the 2018 IEEE 87th Vehicular Technology Conference: VTC2018-Spring, an international conference sponsored by the Institute of Electrical and Electronics Engineers (IEEE) to be held on June 3 – 6.

Quantum Technology and Future Telecommunications

Last year I posted an excerpt from an article in FT which implied that Quantum technology will play a big role in post-5G world. Earlier this month CW held their annual Technology & Engineering Conference (CW TEC). The topic was "The Quantum Revolution is coming". I have to admit that I knew next to nothing before the conference, however now I hope I know just enough to dabble in quantum technology related discussions.

The main question that I had before the conference was 'when will quantum technology be here?'. While there were different answers, depending on what you think Quantum is, I think the answer I feel comfortable is more like 2030 (just in time for 6G?)

There are already some great write-ups of the conference by others, please see links at the bottom of the post. Here are the presentations from the event:

• How to build a universal quantum computer by John Morton, University College London
  
• The end of cryptography as we know it by Michael Brown, Isara Corporation
  
• The quantum challenge and opportunity by Paul Martin, Plextek
  
• The UK Quantum Technology Programme and Funding Opportunities by Richard Murray, Innovate UK

Have researchers moved on past 5G on to 6G Wireless?

As I am active on multiple social networks including blogs, twitter, facebook, linkedin, etc., Its always tricky to be able to share information from one on to another. Some time back I tweeted about the 6G research that seems to have started according to an article in FT.

While everyone is focusing on 5G, research has already started on 6G :-) http://t.co/FvxJvXaxXS via @FT pic.twitter.com/g50hYqsnrN

— Zahid Ghadialy (@zahidtg) May 3, 2015

While I had a few retweets and interactions, I realised that its always challenging to search the tweets so I decided to add this in the blog post, always easier to look it up.

So the FT Article states that:

Even as 5G remains a distant prospect for most mobile users, some scientists have already begun to work on plans for 6G services in the future.

To an extent, terms such as 4G and 5G have become as much about marketing equipment as any single technology breakthrough, with incremental improvements to technical specifications often arbitrarily given names such as 3.5G or 4.5G.

But that has not stopped people from thinking about what 6G could look like — and in the UK at least, the prediction is for a “quantum” leap.

Britain has created a “national quantum strategy” to identify areas where advances in technology will have the greatest impact on daily lives in the future. The strategy was developed by the Quantum Technologies Strategic Advisory Board, a government funded agency, which oversees the £270m programme. 

One of the key goals will be the development of faster communications for mobile devices. The advisory board predicts that the market for quantum products and technology has the potential to become a £1bn industry, even if details of how mobile technology can use quantum theory — science at an atomic level — are thin on the ground.

So why did I suddenly think about 6G? Because I have had a few discussions where the research community feel that they should focus on technologies beyond 5G, something that would be a game changer and would change the way we do communications. To be honest, new ways of communications have been found (like LED-Fi / Li-Fi ) but they have not really been ground breaking.

Do you have any ideas or suggestions, add it as comments.
