An interesting presentation by Patrick Lopez, VP Networks Innovation, Telefónica at NFV & Zero Touch World Congress 2018 about how and why Telefónica is moving to open source. Slides and video embedded below
I recently presented my personal vision of an alternative 5G for rural communities on behalf of Parallel Wireless at the IEEE 5G Summit in Glasgow. I believe that the next few years are going to be crucial for MNOs to decide if they want to cover the rural areas or just continue to focus on built-up areas.
In some cases it may not really be worthwhile for example for a smaller operator to build a cellular IoT network as the returns may not be worth the effort and investment.
I should mention that the caveat is that a lot of alternative 5G approach in my presentation depends on at least one of the satellite megaconstellations being successfully deployed and being fully operational. I am assuming a sensible pricing would be in place anyway as the satellite operators cant keep charging whatever they want for ever.
So here is my alternative 5G vision
Slides (and pictures) are available here for anyone interested. For my slides, jump to page 244. Quite a few other good presentations on 5G too.
An article in EE times summarises this IEEE 5G conference quite well. Available here.
I wrote about PWS 9 years back here. Since then there has been little chance to PWS until recently. According to 3GPP News:
Additional requirements for an enhanced Public Warning System (ePWS) have been agreed at the recent 3GPP TSG SA#79 meeting, as an update to Technical Specification (TS) 22.268. 3GPP Public Warning Systems were first specified in Release 8, allowing for direct warnings to be sent to mobile users on conventional User Equipment (PWS-UE), capable of displaying a text-based and language-dependent Warning Notification. Since that time, there has been a growth in the number of mobile devices with little or no user interface - including wrist bands, sensors and cameras – many of which are not able to display Warning Notifications. The recent growth in the number of IoT devices - not used by human users – also highlights the need for an alternative to text based Warning Notifications. If those devices can be made aware of the type of incident (e.g. a fire or flood) in some other way than with a text message, then they may take preventive actions (e.g. lift go to ground floor automatically). 3GPP SA1 delegates also considered how graphical symbols or images can now be used to better disseminate Warning Notifications, specifically aimed at the following categories of users:
Users with disabilities who have UEs supporting assistive technologies beyond text assistive technologies; and
Users who are not fluent in the language of the Warning Notifications.
Much of the work on enhancing the Public Warning System is set out in the ePWS requirements specification: TS 22.268 (SA1). You should also keep an eye on the 3GPP protocol specifications (CT1, Stage 3 work) in Release 16, covering:
Specifying Message Identifiers for ePWS-UE, especially IoT devices that are intended for machine type communications
Enabling language-independent content to be included in Warning Notifications
The work on ePWS in TS 22.268 (Release 16) is expected to help manufacturers of User Equipment meet any future regulatory requirements dedicated to such products.

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.

Came across Multi Access Management Services (MAMS) a few times recently so here is a quick short post on the topic. At present MAMS is under review in IETF and is being supported by Nokia, Intel, Broadcom, Huawei, AT&T, KT.
I heard about MAMS for the first time at a Small Cell Forum event in Mumbai, slides are here for this particular presentation from Nokia.
As you can see from the slide above, MAMS can optimise inter-working of different access domains, particularly at the Edge. A recent presentation from Nokia (here) on this topic provides much more detailed insight.
From the presentation:
•MAMS
(Multi Access Management Services) is a framework for
-Integrating
different access network domains based on user plane (e.g. IP layer)
interworking,
-with
ability to select access and core network paths independently
-and
user plane treatment based on traffic types
-that
can dynamically adapt to changing network conditions
-based
on negotiation between client and network

Last month, just before the Easter break, I along with some other SIG champions of the Future Devices & Technologies group at CW (Cambridge Wireless) organised an event titled 'Smart Devices of 2025'. Technologies are moving at such an amazing speed that it is not easy to foresee anything beyond 6-8 years. Hence 2025, 7 years from now.
As this was the inaugural event for the revamped SIG, the slides above are my quick introduction to the SIG. We not only talked about the future but we had some nice futuristic devices too. The nuFood 3D Food Printer by Dovetailed printed out some fancy toppings that could go on cheesecake and on other food, making it more appetising. Here is the video on how it works.
All the talks were very informative and very well explained. Its amazing how all of them came together to form a complete picture. The talks are all available here (limited time for non-CW members)
The starting talk by David Wood (@dw2), chair of London Futurists was not only informative and relevant to the subject being discussed but equally entertaining, especially for those who have been in the mobile industry for a long time. He has kindly agreed for me to share his slides which are embedded below.
David talks about NBIC (slide 18) and how it could be combined with Social-tech and Planetary-tech in future to do a lot more than what we can do with it today. While David explains NBIC in his slides, I found this short video on this topic that I think is worth embedding.
It was also good to hear Dr Jenny Tillotson again after a long time. I blogged about smell transmission some 6 years back here. This is something that is still work in progress and probably will be ready by 2025. In the meantime 'Context-Driven Fragrances' can be used for variety of purposes from entertainment to health.
CW (a.k.a. Cambridge Wireless) held a very interesting event titled 'Time for Telecoms' at the Science Museum in London. I managed to record this one talk by Prof. Andy Sutton, who has also kindly shared slides and some other papers that he mentions in his presentation. You can also see the tweets from the event on Twitter.
The video playlist and the presentation is embedded below.
Got an opportunity recently to hear about the connectivity progress, challenges and issues in Africa. Agree that Africa is a very large continent with many different countries in different stages of development but it was nevertheless interesting to look at a high level picture on the progress of connectivity in the continent. The presentation by iDate Digiworld is embedded below.
This year April Fools' Day wasn't as fun as the last one. Couple of reasons being that it was on a Sunday and it coincided with Easter Sunday. Here are some of the jokes that I found interesting.
Sprint's Magic Ball:
It was good to see that the US mobile operator joined the party this year. Their magicball (based on their highly successful Magic Box) advert was really good. Here is the video:
Good to see that they managed to squeeze in references to 5G and small cells
T-Mobile USA has consistently come up with the best tech pranks. Last year they had the OneSie with Human HotSpot and BingeOnUp the year before. This year the re-booted sidekicks was the joke of the day. The video is embedded below. As the description says, T-Mobile’s Sidekick gets a remake! Inspired by the past but stepping boldly into the future, it has revolutionary AI, headphones that double as chargers, personalized GPS guidance by John Legere, and more!
"A top-secret team of Chegg engineers from Zurich spent two years developing a new patent-pending revolutionary proprietary method of making memory foam using special blends of matcha and lavender. Thanks to their discoveries, Chegg’s memory foam actually improves your memory. Got a final exam tomorrow? Sleep on it. Got a lab report due? Sleep on it. Need to outline your entire thesis? Sleep on it."
"Tongueprinting technology analyzes thousands of tiny bumps called papillae, as well as factors such as shape, size, and temperature to accurately identify yourself by licking your phone. This technology will be the mouthpiece of Pindrop’s latest authentication and anti-fraud solutions." Video:
