I recently did a small presentation on 3GPP Security, looking at the how the security mechanism works in mobile cellular networks; focusing mainly on signaling associated with authentication, integrity protection and ciphering / confidentiality. Its targeted towards people with basic understanding of mobile networks. Slides with embedded video below.
You can also check-out all such videos / presentations at the 3G4G training section.
Satellites has been an area of interest of mine for a while as some of you know that I used to work as Satellite Applications & Services Programme manager at techUK. I have written about how I see satellites complementing the mobile networks here and here.
Its good to see that there is some activity in 3GPP going on about satellites & Non-terrestrial networks (NTN) in 5G. While there are some obvious roles that satellites can play (see pic above), the 5G work is looking to cover a lot more topics in details.
3GPP TR 38.913: Study on scenarios and requirements for next generation access technologies looks at 12 different scenarios, the ones relevant to this topic ate Air to ground, Light aircraft and Satellite to terrestrial.
3GPP TR 38.811: Study on New Radio (NR) to support non terrestrial networks (Release 15) covers this topic a bit more in detail. From looking at how satellites and other aerial networks work in general, it looks at the different NTN architecture options as can be seen above.
3GPP also released a news item on this topic last week. It also refers to the above TR and a new one for Release 16. The following from 3GPP news:
The roles and benefits of satellites in 5G have been studied in 3GPP Release 14, leading to the specific requirement to support satellite access being captured in TS 22.261 - “Service requirements for next generation new services and markets; Stage 1”, recognizing the added value that satellite coverage brings, as part of the mix of access technologies for 5G, especially for mission critical and industrial applications where ubiquitous coverage is crucial.
Satellites refer to Spaceborne vehicles in Low Earth Orbits (LEO), Medium Earth Orbits (MEO), Geostationary Earth Orbit (GEO) or in Highly Elliptical Orbits (HEO).
Beyond satellites, Non-terrestrial networks (NTN) refer to networks, or segments of networks, using an airborne or spaceborne vehicle for transmission. Airborne vehicles refer to High Altitude Platforms (HAPs) encompassing Unmanned Aircraft Systems (UAS) - including tethered UAS, Lighter than Air UAS and Heavier than Air UAS - all operating at altitude; typically between 8 and 50 km, quasi-stationary.
These Non-terrestrial networks feature in TSG RAN’s TR 38.811“Study on NR to support non-terrestrial networks”. They will:
A second study item, the “Study on using Satellite Access in 5G” is being addressed in Working Group SA1. It shall lead to the delivery of the corresponding Technical Report TR 22.822 as part of Release 16.
This study will identify use cases for the provision of services when considering the integration of 5G satellite-based access components in the 5G system. When addressing the integration of (a) satellite component(s), use cases will identify new potential requirements for 5G systems addressing:
Anyway, back in Dec. 3GPP and Virtual Reality Industry Forum (VRIF) held a workshop on VR Ecosystem & Standards. All the materials, including agenda is available here. The final report is not there yet but I assume that there will be a press release when the report is published.
While there are some interesting presentations, here is what I found interesting:
From presentation by Gordon Castle, Head of Strategy Development, Ericsson
From presentation by Martin Renschler, Senior Director Technology, Qualcomm
Wikipedia entry. According to the Nokia presentation, Facebook’s marketing people call this “6DOF;” the engineers at MPEG call it “3DOF+.”
XR is 'cross reality', which is any hardware that combines aspects of AR, MR and VR; such as Google Tango.

There are many valuable insights in this talk and the other talks from this conference. All the videos from the IET conference are available here and they are worth your time.
Over the last year or so, I have heard quite a few discussions and read many articles around why QUIC is so good and why we will replace TCP with QUIC (Quick UDP Internet Connection). One such article talking about QUIC benefits says:
QUIC was initially developed by Google as an alternative transport protocol to shorten the time it takes to set up a connection. Google wanted to take benefits of the work done with SPDY, another protocol developed by Google that became the basis for the HTTP/2 standard, into a transport protocol with faster connection setup time and built-in security. HTTP/2 over TCP multiplexes and pipelines requests over one connection but a single packet loss and retransmission packet causes Head-of-Line Blocking (HOLB) for the resources that were being downloaded in parallel. QUIC overcomes the shortcomings of multiplexed streams by removing HOLB. QUIC was created with HTTP/2 as the primary application protocol and optimizes HTTP/2 semantics.
What makes QUIC interesting is that it is built on top of UDP rather than TCP. As such, the time to get a secure connection running is shorter using QUIC because packet loss in a particular stream does not affect the other streams on the connection. This results in successfully retrieving multiple objects in parallel, even when some packets are lost on a different stream. Since QUIC is implemented in the userspace compared to TCP, which is implemented in the kernel, QUIC allows developers the flexibility of improving congestion control over time, since it can be optimized and better replaced compared to kernel upgrades (for example, apps and browsers update more often than OS updates).
Georg Mayer mentioned about QUIC in a recent discussion with Telecom TV. His interview is embedded below. Jump to 5:25 for QUIC part only

Below are some good references about QUIC in case you want to study further.
As a continuation of 'Control and User Plane Separation of EPC nodes (CUPS) in 3GPP Release-14', here is another tutorial on Service Base Architecture (SBA) for the 5G Core.
The slides (with video) is embedded below but there are quite a few tutorials on 5G available on 3G4G page here.
What is the next step in evolution of SON? Artificial Intelligence obviously. The use of artificial intelligence (AI) techniques in the network supervisory system could help solve some of the problems of future network deployment and operation. ETSI has therefore set up a new 'Industry Specification Group' on 'Experiential Networked Intelligence' (ISG ENI) to develop standards for a Network Supervisory assistant system.
The ISG ENI focuses on improving the operator experience, adding closed-loop artificial intelligence mechanisms based on context-aware, metadata-driven policies to more quickly recognize and incorporate new and changed knowledge, and hence, make actionable decisions. ENI will specify a set of use cases, and the generic technology independent architecture, for a network supervisory assistant system based on the ‘observe-orient-decide-act’ control loop model. This model can assist decision-making systems, such as network control and management systems, to adjust services and resources offered based on changes in user needs, environmental conditions and business goals.
The introduction of technologies such as Software-Defined Networking (SDN), Network Functions Virtualisation (NFV) and network slicing means that networks are becoming more flexible and powerful. These technologies transfer much of the complexity in a network from hardware to software, from the network itself to its management and operation. ENI will make the deployment of SDN and NFV more intelligent and efficient and will assist the management and orchestration of the network.
We expect to complete the first phase of ENI work in 2019. It will include a description of use cases and requirements and terminology, including a definition of features, capabilities and policies, which we will publish in a series of informative best practice documents (Group Reports (GRs)).
Will see how this goes.
This year at MWC, I took the time out to go and see as many companies as I can. My main focus was looking at connectivity solutions, infrastructure, devices, gadgets and anything else cool. I have to say that I wasn't too impressed. I found some of the things later on Twitter or YouTube but as it happens, one cannot see everything.
I have to be honest, haven't seen a WOW demo yet at #MWC18. While there are lots of interesting stuff, it's all the same, old and tired stuff.— Zahid Ghadialy (@zahidtg) February 26, 2018
I will be writing a blog on Small Cells, Infrastructure, etc. later on but here are some cool videos that I have found. As its a playlist, if I find any more, it will be added to the same playlist below.
The big vendors did not open up their stands for everyone (even I couldn't get in 😉) but the good news is that most of their demos is available online. Below are the name of the companies that had official MWC 2018 websites. Will add more when I find them.
Network Equipment Vendors
Did I miss anyone? Feel free to suggest links in comments.
During the mobile world congress, I was pleasantly surprised to see how LoRa ecosystem keeps getting larger. There was also an upbeat mood within the LoRa vendor community as it keeps winning one battle after another. Here is my short take on the technology with an unbiased lens.
It’s seems LoRa is quietly getting some traction, particularly when it comes to industrial / vertical markets. #MWC18pic.twitter.com/KQ6G7JjTU9— Ben Wood (@benwood) February 28, 2018
To start with, lets look at this short report by Tom Rebbeck from Analysys Mason. The PDF can be downloaded after registering from here.
These points lead to a final observation about network deployments – many operators are launching multiple technologies. Of the 26 operators with publicly-announced interest in LTE-M networks, 20 also have plans for other networks;
• 14 will combine it with NB-IoT
• four will offer LTE-M and LoRa and
• two, Softbank and Swisscom, are working with LoRa, LTE-M and NB-IoT.
We are not aware of operators also owning Sigfox networks, though some, such as Telefónica, are selling connectivity provided by a Sigfox network operator.
The incremental cost of upgrading from NB-IoT or LTE-M to both technologies is relatively small. Most estimates put the additional cost at less than an additional 20% – and sometimes considerably less. For many operators, the question will be which technology to prioritise, and when to launch, rather than which to choose.
The reasons for launching multiple networks appear to be tactical as much as strategic. Some operators firmly believe that the different technologies will match different use cases – for example, LoRa may be better suited to stationary, low bandwidth devices like smart meters, while LTE-M, could meet the needs of devices that need mobility, higher bandwidth and support for voice, for example a personal health monitor with an emergency call button.
But, a fundamental motive for offering multiple networks is to hedge investments. While they may not admit it publicly, operators do not know which technology will gain the most traction. They do not want to lose significant, lucrative contracts because they have backed the wrong technology. Deploying both LTE-M and NB-IoT – or LoRa – adds little cost and yet provides a hedge against this risk. For operators launching LoRa, there has been the added benefit of being early to market and gaining experience of what developers want and need from LPWA networks. This experience should help them when other technologies are deployed at scale.
The following is from MWC 2018 summary by ABI Research:
LPWA network technologies continue to gather momentum with adoption from a growing ecosystem of communications service providers (CSPs), original equipment manufacturers (OEMs) and IoT solution providers. LPWA networks are central to the connectivity offerings from telcos with support for NB-IoT, LTE-M, LoRaWAN, and SIGFOX. Telefonica highlighted SIGFOX as an important network technology along with NB-IoT and Cat M in its IoT connectivity platform. Similarly, Orange and SK Telecom emphasized on their continued support for LoRaWAN along with Cat M in France and South Korea. On the other hand, Vodafone and Deutsche Telekom, while aggressively pursuing deployment of NB-IoT networks, currently have mostly large scale POCs on their networks.
Smart meters — Utilities are demanding that meter OEMs and technology solution providers deliver product design life of at least 15 years for battery operated smart water and gas meters. LPWA technologies, such as NB-IoT, LoRaWAN, SIGFOX and wireless M-bus, that are optimized for very low-power consumption and available at low cost are clearly emerging as the most favored LPWA solutions.
The following picture is from Ovum post MWC-2018 Webinar:
There are also few announcements / news from LoRa world just to highlight how the ecosystem is thriving:
So someone recently asked me is LoRa is the new WiMax? The answer is obviously a big NO. Just look at the LoRa alliance members in the picture above. Its a whole ecosystem with different players having different interests, working on a different part of the ecosystem.
NB-IoT & LTE-M will gain ground in the coming years but there will always be a place for other LPWA technologies like LoRa.
Finally, here is a slide deck (embedded below) that I really like. The picture above very nicely illustrates that LoRaWAN and Cellular complement each other well. Maybe that is the reason that Orange is a big supporter of LoRa.
So for operators who are just starting their IoT journey or smaller operators who are unsure of the IoT potential, may want to start their journey with LoRa to play around and understand the business cases, etc. In the meantime LTE-M and NB-IoT ecosystem will mature with prices coming down further and battery time improving. That may be the right time to decide on the way forward.
Well, it was officially 3G4G's first Mobile World Congress so I took time to go through the different booths, demos, etc. and compile a small presentation
The presentation (embedded below and can be downloaded from Slideshare) covers the following companies:Our first official #MWC18 thanks to @Parallel_tw. Do wave to @zahidtg when you see him around pic.twitter.com/ETR9oU21z9— 3G4G (@3g4gUK) February 26, 2018
Do let me know if you found it useful
Its been a while since I wrote about 5G security in this fast changing 5G world. If you are new to 3GPP security, you may want to start with my tutorial here.
3GPP SA3 Chairman, Anand R. Prasad recently mentioned in his LinkedIn post:
5G security specification finalized! Paving path for new business & worry less connected technology use.
3GPP SA3 delegates worked long hours diligently to conclude the specification for 5G security standard during 26 Feb.-2 Mar. Several obstacles were overcome by focussed effort of individuals & companies from around the globe. Thanks and congrats to everyone!
All together 1000s of hours of work with millions of miles of travel were spent in 1 week to get the work done. This took 8 meetings (kicked off Feb. 2017) numerous on-line meetings and conference calls.
Excited to declare that this tremendous effort led to timely completion of 5G security specification (TS 33.501) providing secure services to everyone and everything!
The latest version of specs is on 3GPP website here.
ITU also held a workshop on 5G Security in Geneva, Switzerland on 19 March 2018 (link). There were quite a few interesting presentations. Below are some slides that caught my attention.
The picture in the tweet above from China Mobile summarises the major 5G security issues very well. 5G security is going to be far more challenging than previous generations.Major 5G Security Issues via Min Zuo, China Mobile #RANSplit#NetworkSlicing#SBA#NFV#SDN#CloudComputing#MECpic.twitter.com/GD8EMNP1Fk— 3G4G (@3g4gUK) March 20, 2018
The presentation by Haiguang Wang, Huawei contained a lot of good technical information. The picture at the top is from that presentation and highlights the difference between 4G & 5G Security Architecture.
New entities have been introduced to make 5G more open.
EPS-AKA vs 5G-AKA (AKA = Authentication and Key Agreement) for trusted nodes
EAP-AKA' for untrusted nodes.
Slice security is an important topic that multiple speakers touched upon and I think it would continue to be discussed for a foreseeable future.
Dr. Stan Wing S. Wong from King’s College London has some good slides on 5G security issues arising out of Multi-Tenancy and Multi-Network Slicing.
Peter Schneider from Nokia-Bell Labs had good slides on 5G Security Overview for Programmable Cloud-Based Mobile Networks
Sander Kievit from TNO, a regular participant of working group SA3 of 3GPP on behalf of the Dutch operator KPN presented a view from 3GPP SA3 on the Security work item progress (slides). The slide above highlights the changes in 5G key hierarchy.
The ITU 5G Security Workshop Outcomes is available here.
ETSI Security Week 2018 will be held 11-15 June 2018. 5G security/privacy is one of the topics.
There is also 5GPPP Workshop on 5G Networks Security (5G-NS 2018), being held in Hamburg, Germany on August 27-30, 2018.
In the meantime, please feel free to add your comments & suggestions below.

Did I miss any good ones?
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.
Slides available from techUK website here.
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.
The papers referred to in the presentation/video available as follows:
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.
Finally, here is another small presentation (with embedded video) on Telepresence Robots that I did.
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:
The slides provide much more details, including the different use cases (pic below) for integrating LTE and Wi-Fi at the Edge.

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.

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:
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:
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.
