5G Evolution with Matthew Baker, Nokia


I wrote a summary of CW (Cambridge Wireless) TEC conference here a couple of months back. The last session was on "Getting ready for Beyond-5G Era". Matthew Baker, Head of Radio Physical Layer & Co-existence Standardization, Nokia Bell Labs was one of the speakers. His talk provided a summary of 3GPP Rel-15 and then gave a nice and short summary of all the interesting things coming in Rel-16 and being planned for Rel-17. The slides from his presentation is embedded below:



Nokia also created a short video where Matthew talks about these new features. It's embedded below:

Guest Post: Exploring Network Convergence of Mobile, Broadband and Wi-Fi

This is a guest post by Ben Toner, Founder and Director, Numerous Networks


Are multiple networks better than one?

How many articles have you read with a title similar to "Which technology is better, 5G or Wi-Fi6?" If, like me, you regularly use Wi-Fi and cellular (I still use 4G though) then you might find it hard to take sides.

Enter Network Convergence - the concept of bringing multiple networks together to get the best of them all. Imagine, as an end user, not having to decide which network to use but instead feeling satisfied that your data was traversing the best combination of networks at that moment in time.

Imagine a business traveler being connected to Wi-Fi which is slow or busy while trying to take that all important conference call while sitting in an airport. Because you are roaming you want to use that Wi-Fi but you do not want to compromise the video call quality. If your network and device could work together to use just enough cellular data to supplement the slow Wi-Fi so that you stayed within your daily roaming quota but never lost a moment in the video call - then you would probably be very happy with that service. Better still, as you start walking off, if the call transitioned from Wi-Fi to cellular with no dropouts or hangup then you might be delighted!

Earlier I underlined best because that in itself is somewhat complicated.  The example above is easy to desribe but quite hard for to achieve within a framework where all possible scenarios are handled that well, for every user. The common questions which need to be factored into any such choice are:
  • What do I as the end user want? 
  • What performance can each network deliver. 
  • How important is the transfer of content at that time and 
  • How much am I willing to pay for it (how many MB of my data plan am I willing to use?). 

This is one of the challenges that we cannot easily solve today, but technology is being developed to help in that process. The operators and device vendors are working within standardisation to develop technology which can provide such a converged service. However at this time there is still a rules mechanism behind it all which does not really describe how user input and preference is going to be captured.

In the last 10 years I have witnessed many battles within service providers when deciding what "one size fits all" service to offer everyone when deciding how to make service provider Wi-Fi available to their customers; all fuelled by my points above.

A lot of concepts are well designed and somewhat mature but deciding exactly what will be implemented in standards is currently ongoing.

In the following slides and video I introduce this whole concept of Network Convergence. The following content introduces the concept and then takes a detailed look at the ATSSS; technology being defined in 3GPP. I also have highlighted the technologoies you can get hold of today to try out network convergence.

I encourage you all to download the example technologies and try convergence for yourself. I'm eager to hear opinions of what technologies work best for each of you. And better still, what is not being provided which you think should be...

Looking forward to your feedback and answering your questions...

Cell-free Massive MIMO and Radio Stripes


I wrote about "Distributed Massive MIMO using Ericsson Radio Stripes" after MWC 2019 here. I found it a very interesting concept and it will certainly take a few years before it becomes a reality.

Emil Björnson, Associate Professor at Linköping University have produced couple of videos on this topic. I am embedding both of them below for anyone who may be interested.

"A New Look at Cell-Free Massive MIMO" - based on technical paper from PIMRC 2019 on how to design Cell-free Massive MIMO systems that are both scalable and achieve high performance.



Worth noting the following about this video (based on video comments):
  • There are some minor issues with the sudio
  • Cell-free Massive MIMO is particularly for stadiums, streets, and places with many users or where it is hard to provide sufficient network quality with other methods.
  • This concept is still 4-5 years away from being ready to be practically deployed. It should be ready for later part of 5G, probably 5.5G

"Reinventing the Wireless Network Architecture Towards 6G: Cell-free Massive MIMO and Radio Stripes" looks at the motivation behind Cell-free Massive MIMO and how it can be implemented in 6G using radio stripes.



Worth noting the following on this video (based on video comments):

  • It may be possible that multiple frequency bands can be handled in the same radio stripe. If it is found to be possible then every other antenna  processing unit could manage a different band.
  • In principle, you can make the stripe as long as you need. But you probably need to divide it into segments since the power is supplied from one end of a stripe and it will only reach a limited distance (roughly up to 1 km). There are many implementation ideas and it remains to be seen what works out well in practice.

I am looking forward to see it work as it can solve coverage issues in many tricky scenarios.

Summary of #CWTEC 2019 Conference: 5G, Satellites & Magic MIMO

I was involved in helping organise yet another CW TEC conference this year. The topic was quite interesting and we had some brilliant speakers. Some of the excellent presentations were shared too, links below. Here is a very quick summary of the event, linking also to couple of excellent summaries below.

The topic was a bit unusual and it rhymed very well with the attendees which were from many different backgrounds, from 5G, communications, satellites, electronics, T&M companies, etc. Here is the opening video that will show you the motivations behind this



The day started with a breakfast briefing from Cambridge Consultants that looked at how Massive MIMO is the key to unlocking 5G User Experiences. Presentations available here.


Session 1 was titled "What has Massive MIMO ever done for us?". The narrative for the session was as follows:
Clearly the desire for more and more capacity in cellular networks has driven the industry to find more and more novel techniques. The work done over the years and boosted by Tom Marzetta’s article titled “Noncooperative Cellular Wireless with Unlimited Numbers of Base Station Antennas” has set high expectations for this emergent technology, so much so the term Magic MIMO has been coined. However, how significant is it into today’s early 5G rollout and what can we expect over the coming years? Are there still further enhancements we should expect to see?

There were 3 talks as follows:
  • Sync Architectures for 5G NR by Chris Farrow, Technical Manager, Chronos Technology (slides)
  • Three UK’s RAN transformation: Spectrum, RAN architecture strategy, Why? by Dr Erol Hepsaydir, Head of RAN and Devices Strategy and Architecture, Three UK (slides)
  • Active antenna systems in RAN: performance, challenges and evolution by Anvar Tukmanov, Wireless Research Manager, BT (slides)


Session 2 looked at "Non-Terrestrial & Hybrid Networks". The narrative for the session was as follows:
There are different initiatives underway to make satellite and other non-terrestrial networks as part of 5G. In addition, many different mobile operators have demonstrated compelling use-cases with drones, balloons and other aerostats. Other innovative approaches like European Aviation Network uses a hybrid-network using terrestrial network supported by a satellite connection as a backhaul for in-flight Wi-Fi. In addition to latency, what other challenges are stopping mass adoption of Non-terrestrial and Hybrid networks? What about advanced features like slicing, etc.?

There were 3 talks as follows:

  • Opportunities for blending terrestrial and satellite technologies by Dr Jaime Reed, Director, Consulting, Space, Defence and Intelligence, CGI (slides)
  • Non-terrestrial Networks: Standardization in 5G NR by Dr Yinan Qi, Senior 5G Researcher, Samsung R&D Institute UK (slides)
  • Satellites and 5G: A satellite operator’s perspective by Simon Watts, Principal Consultant, Avanti Communications (slides)


Session 3 looked at "5G: A Catalyst for Network Transformation". The narrative was as follows:
5G has set high expectations in the user as well as operator community. While eMBB can be supported with an upgrade of existing 4G infrastructure, URLLC and mMTC may require massive change in the network architecture. Operators have already started the transformation process with backhaul upgrades, new data centers, distributed core and cloud rollouts, etc. How are networks evolving to accommodate these deep changes? What other changes will be required in the network to support the growth until the next new generation arrives?
This session featured 3 talks as well
  • An Introduction to Open RAN Concept by Zahid Ghadialy, Senior Director, Strategic Marketing, Parallel Wireless UK & EMEA (slides)
  • Powering the successful deployment of 5G infrastructure by David George, Vice President of EMEA and APAC, Sitetracker (slides)
  • The 5G transformation: no sweet without sweat by Antonella Faniuolo, Head of Network Strategy, Planning, Digital & Optimisation, Vodafone (slides)


The final session topic was "Getting ready for Beyond-5G Era". The narrative was as follows:
Many technologies like Full duplex, etc. that were originally intended to be part of 5G were not able to make it into the standards. Along with these, what other revolutionary changes are needed to make Beyond-5G technologies not only fulfil the vision, ambition and use-cases that were originally envisaged for 5G but to take it a step further and make it a game changer.
This session featured 3 talks as well, as follows:
  • Thinking Beyond 5G: Projects and Initiatives by Alan Carlton, Vice President, InterDigital Europe (slides not available)
  • 5G Evolution: Progressive enhancement and new features for new markets by Matthew Baker, Head of Radio Physical Layer and Coexistence Standardization, Nokia (slides)
  • Why 6G’s design goals need far more than just radio & core innovation by Dean Bubley, Analyst & Futurist, Disruptive Analysis (slides not available)
And my personal highlight was that I launched World's first coloured 5G tie


Hopefully you found the presentations shared as useful. Please also read the summaries of CWTEC provided below.

Examples of 5G Use Cases & Applications


I recently did another 5G training for CW (Cambridge Wireless) & UK5G. One of the sections in that was about Use Cases. A very common questions that people ask is what can 5G do that 4G can't. The answer frankly is sometimes not very straightforward.


While you can get a very high speed and very reasonable latency 4G system, it's not necessarily a commonplace. Similarly 5G is a bit over-hyped. There is a lot of potential in the technology but the theory may not translate into practice. Take for example millimeter wave. There is a large amount of bandwidth that can be available to each operator in this spectrum. The laws of physics however restrict how far mmWave can travel and also the fact that mmWave does not penetrate through glass, walls, etc. Does that mean that an indoor 5G system would be required to complement an outdoor one? Would Wi-Fi be able to complement cellular in-building? There are many unanswered questions at the moment.

There is also the debate around 5G icon displayed on your smartphones. When you see 5G, would it really be 5G or just re-branded 4G? Light Reading has explained this issue nicely here.

So while there are many potential applications & use cases that will benefit from 5G in the long run, the answers are not that easily available today. Anyhow, the collection of videos and slides embedded below will provide you with an insight on how different vendors and operators are looking at potentially using 5G.






The latest version of these slides are available to download from UK5G website here.

Webinar: Where Edge Meets Cloud by Dean Bubley


Dean Bubley, Outspoken Telecoms & Mobile Industry Analyst, Consultant & Chair/Speaker on Networks, Wireless, Internet, AI & Futurism (as stated in his LinkedIn profile), recently did a webinar on Edge computing for Apis Training. The video recording is available online and embedded below.


Couple of things worth highlighting (but do listen to the webinar, it's got lots of interesting stuff) is as shown in the picture above and below. One of the benefits of Edge is Low latency. If that is the driver then you need to know where your Edge should be because latency will be affected based on the location. Another important point worth remembering is how many Edge-compute facilities can you afford. Latency & the number of facilities are linked to each other so worth thinking about in the beginning as it may not be straightforward to change later.



Anyway, here is the recording of the webinar.

Wi-Fi 6 (a.k.a. 802.11ax) and other Wi-Fi enhancements

Last year I wrote about how Wi-Fi is getting new names. 802.11ax for example, the latest and greatest of the Wi-Fi standards is known as Wi-Fi 6. There were many announcements at MWC 2019 about WiFi 6, some of which I have captured here.

I came across a nice simple explanatory video explaining Wi-Fi 6 for non-technical people. Its embedded below.


The video is actually sponsored by Cisco and you can read more about Wi-Fi 6 and comparison of Wi-Fi 6 and 5G on their pages.

At MWC19, Cisco was showing Passpoint autoconnectivity on Samsung Galaxy S9, S9+ or Note 9 device. According to their blog:

Together, we’re working to provide a better bridge between mobile and Wi-Fi networks. At Mobile World Congress in Barcelona we’ll show the first step in that journey. Anyone using a Samsung Galaxy S9, S9+ or Note 9 device (and those lucky enough to have an early Galaxy S10) over the Cisco-powered guest wireless network will be able to seamlessly and securely connect – without any manual authentication. No portal, no typing in passwords, no picking SSIDs, no credit cards — just secure automatic connectivity.  How?  By using credentials already on your phone, like your operator SIM card.  Even if your operator doesn’t currently support Passpoint autoconnectivity, your Samsung smartphone will!  As a Samsung user, you already have an account for backups and device specific applications. This credential can also be used for a secure and seamless onboarding experience, supporting connectivity to enterprise, public and SP access networks.

It's worth mentioning here that the WPA2 authentication algorithm is being upgraded to WPA3 and we will see broad adoption this year, in conjunction with 802.11ax. See the tweet for details

Broadcom announced their new BCM43752, Dual-Band 802.11ax Wi-Fi/Bluetooth 5 Combo Chip. Motley Fool explains why this is interesting news:

The chip specialist is rounding out its Wi-Fi 6 portfolio to address lower price points.

When Samsung announced its Galaxy S10-series of premium smartphones, wireless chipmaker Broadcom announced, in tandem, that its latest BCM4375 Wi-Fi/Bluetooth connectivity combination chip is powering those new flagship smartphones. That chip was the company's first to support the latest Wi-Fi 6 standard, which promises significant performance improvements over previous-generation Wi-Fi technology.

The BCM4375 is a high-end part aimed at premium smartphones, meaning that it's designed for maximum performance, but its cost structure (as well as final selling price) is designed for pricier devices that can handle relatively pricey chips.

Broadcom explains that the BCM43752 "significantly reduces smartphone bill of materials by integrating [radio frequency] components such as power amplifiers (PAs) and low-noise amplifiers (LNAs) into the device."

The idea here is simple: Since these components are integrated in the chip that smartphone makers are buying from Broadcom, those smartphone makers won't need to buy those components separately.

In the press release, Broadcom quoted Phil Solis, research director at the market research company IDC, as saying that this chip "reduced costs by going down to single core, 2X2 MIMO for Wi-Fi, integrating the PAs and LNAs, and offering flexible packaging options while keeping the same functionality as their flagship combo chip." 

Broadcom explains that this chip is targeted at "the broader smartphone market where high performance and total solution cost are equally important design decisions."

In addition to these, Intel showed a demo of Wi-Fi 6 at 6GHz. Most people are aware that Wi-Fi uses 2.4 GHz, 5 GHz & 60 GHz band. According to Wi-Fi Now:

So why is that important? Simply because 6 GHz Wi-Fi is likely the biggest opportunity in Wi-Fi in a generation – and because Intel’s demo shows that Wi-Fi chipset vendors are ready to pounce on it. The demonstration was a part of Intel’s elaborate Wi-Fi 6 (802.11ax) demonstration set at MWC.

“When this enhancement [meaning 6 GHz spectrum] to Wi-Fi 6 rolls out in the next couple of years, it has the potential to more than double the Wi-Fi spectrum with up to 4x more 160 MHz channel deployment options,” said Doron Tal, Intel’s General Manager Wireless Infrastructure Group, in his blog here. Doron Tal emphasises that the prospect of including 6 GHz bands in Wi-Fi for the time being realistically only applies to the US market.

Intel also says that a growing number of currently available PCs already support 160 MHz channels, making them capable of operating at gigabit Wi-Fi speeds. This means that consumers will get ‘a pleasant surprise’ in terms of speed if they invest in a Wi-Fi 6 home router already now, Intel says.

It may however take a while before US regulator FCC finally rules on allowing Wi-Fi to operate in the 6 GHz bands. Right now the FCC is reviewing dozens of response submissions following the issuing of the NPRM for unlicensed 6 GHz operation – and they will likely have their hands full for months while answering a litany of questions as to prospective new 6 GHz spectrum rules.

Also an important part of the 6 GHz story is the fact that the IEEE only weeks ago decided that – as far as the 802.11 standards are concerned – only Wi-Fi 6 (802.11ax) will be specified to operate in the 6 GHz band. That means 6 GHz will be pristine legacy-free territory for Wi-Fi 6 devices.

That brings us to the Wi-Fi evolution that will be coming after 802.11ax. IEEE 802.11 Extremely High Throughput (EHT) Study Group was formed late last year that will be working on defining the new 802.11be (Wi-Fi 7?) standards. See tweet below:

The interesting thing to note here is that the Wi-Fi spectrum will become flexible to operate from 1 GHz to 7.125 GHz. Of course the rules will be different in different parts of the world. It will also have to avoid interference with other existing technologies like cellular, etc.

According to Fierce Wireless, Huawei has completed a global deployment of its enterprise-class Wi-Fi 6 products under the new AirEngine brand. Speaking at the company’s Global Analyst Summit, Huawei said its Wi-Fi 6 products have been deployed on a large scale in five major regions worldwide.

Back at MWC, Huawei was showing off their Wi-Fi 6 enabled CPEs. See tweet below:

Huawei has many different enterprise networking products that are already supporting Wi-Fi 6 today. You can see the details along with whitepapers and application notes here. In addition, the Top 10 Wi-Fi 6 misconceptions are worth a read, available here.

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.

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?


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.

X-Ray vision Nokia 9 PureView

The Nokia 9 PureView has plenty of cameras on its back, but did you know that the black sensor isn’t a 3D ToF camera but rather an X-Ray sensor? Can be unlocked with the new Nokia X-Ray app in Play Store


"Digi-U" from Ericsson Digital


Parallel Wireless Adds AMPS (1G) Capabilities to Their Unified ALL G Architecture


From the press release:

Worlds First Fully Virtualized AMPS (vAMPS) to enable Modernization and Cost Savings

Parallel Wireless vAMPS is compatible with: Total Access Communications Systems (TACS) in the U.K.; Nordic Mobile Telephone (NMT) System in Scandinavia; C450 in Germany; and NTT System in Japan, among others, and will allow global operators to modernize their 1G infrastructure. The 1G vAMPS solution is also software upgradable to vD-AMPS, for operators who wish to follow that path.


Truphone foldable SIM (F-SIM) for Foldable Smartphones

F-SIM – the foldable SIM – designed especially for the new foldable smartphones and tablets demonstrated at this February’s MWC Barcelona, including Huawei’s Mate X and Samsung’s Galaxy Fold.

Widely tipped as the next generation in SIM technology, the foldable SIM works on minute hinges that allow it to fold smaller than any previous SIM form factor. Made specifically for foldable phones and other devices, Truphone’s latest innovation fulfils on its broader brand promise to engineer better connections between things, people and business—anywhere in the world.

The F-SIM comes in ‘steel grey’ and, for only £5 more, ‘hot pink’. Pricing structures vary depending on data, storage, roaming charges and device model.

Drones at Mobile World Congress 2019 and my upcoming webinar on 5G at #MWC19


Mobile World Congress featured many different drones for many different purposes and applications. While I wouldn't claim to have seen all or even most of them, I managed to go to the GSMA seminar 'The Internet of the Skies – Connecting Drones'. Key topics of the seminar included:

  • The support of safe BVLOS (Beyond Visual Line Of Sight) and autonomous operation of unmanned aircraft (UA)
  • The use of mobile connectivity to enhance the efficiency and effectiveness of UA, by enabling BVLOS operation, supporting real-time data transmissions from on-board cameras and sensors
  • Mobile connectivity requirements for registration and identification, flight planning and approval, the transmission of meteorological information, geo-fencing, geo-caging and tracking

The best thing is that the presentations are available for anyone interested. Link at the bottom of this post. I have embedded some videos from the seminar in the playlist as well.


During the seminar, Telefônica talked about their fire fighting Antifire drones which are helping detect, survey and combat fires before, during and after a fire breaks out.


Turkcell talked about their Dronecell. The 5G connected drone can be used for many different purposes from inspection, photos and videos to providing temporary coverage in case of disasters. One of the interesting use cases was also surveillance (see video). They are also working with a local drone company, see here. For Dronecell they are testing with different vendors like Huawei, Airspan, etc. and also have their own hardware (see pic above).


The Latvian mobile operator Mans LMT talked about how Drones in combination with Sensors and AI can provide endless opportunities. In addition drones can also be used for delivering goods and rescue missions. Finally, LMT with Lufthansa Systems are working on a mobile, connected UTM platform for drone solutions and traffic management (see video below).



In addition enjoyed a virtual ride in Ooredoo’s 5G-enabled Aerial Taxi. Also happened to bump into Robert Joyce who used to work for Telefonica O2 UK and used to be very active in O2's small cells rollout during 2012 London Olympics. See here, here & here.

Huawei showed SkySite: A Drone with 5G base station & '5G Book' RRU. I blogged about it here.

Saudi Telecom Company (STC) had a drone flight simulator. I didn't see it but tweet below


There were 10 Catalonian companies showing smart drones. Tweet below



Finally, Samsung Electronics, Cisco and Orange unveiled "A Drone carrying a very low latency, high-quality video system is piloted from the Orange booth at the Fira de Barcelona. The drone, which is located outdoors at an Orange datacenter, carries a 5G router (CPE) that is used to transfer commands to the drone and transmit a high-quality video feed with low latency. At the Orange booth, the pilot can be seen controlling the drone by using a 5G tablet. Aeromedia, a leading drone operator, collaborated in this demo." Sadly, I didn't manage to find this and couldn't see any videos either.


Here is a video playlist of Drones from MWC.






I am also running a webinar next week looking at 5G @ MWC 2019 on behalf of Parallel Wireless (#PWTechTrain) . Along with drones, I plan to talk about lot more things. Register here.
