Holographic Display - The *Wow* Demo from MWC 2022

(click image to see larger picture)

We often associate holograms with futuristic technology and even 6G nowadays but what if holograms could be done in a very simple way just by playing with light? 

This is a *wow* demo from Japan Pavilion in Hall 4 at #MWC22 pic.twitter.com/0SYPBPCB8E

At Mobile World Congress 2022, the demo that impressed me most was by a Japanese company called Asukanet. Their ASKA 3D Plate projects images in mid air. This in combination with a 3D sensor allows to manipulate the display without touching. It may be easier to understand this by looking at how this works in the largest convenience store in Japan as shown in the video below:

This is the demo video that I got at MWC

This is us playing with the hologram

While it may not be straightforward, it would complement our smartphones or tablets display nicely. 

You can watch some of the use cases on their page here.

Let me know what you think?

Are there 50 Billion IoT Devices yet?

Detailed post below but if you are after a quick summary, it's in the picture above.

Couple of weeks back someone quoted that there were 50 billion devices last year (2020). After challenging them on the number, they came back to me to say that there were over 13 billion based on GSMA report. While the headline numbers are correct, there are some finer details we need to look at.

It all started back in 2010 when the then CEO of Ericsson announced that there will be 50 Billion IoT Devices by 2020. You could read all about it here and see the presentation here. While it doesn't explicitly say, it was expected that the majority of these will be based on cellular technologies. I also heard the number 500 Billion by 2030, back in 2013.

So the question is how many IoT devices are there today and how many of these are based on mobile cellular technologies?

The headline number provided by the GSMA Mobile Economy report, published just in time for MWC 2021, is 13.1 billion in 2020. It does not provide any further details on what kind of connectivity these devices use. I had to use my special search skills to find the details here.

As you can see, only 1.9 billion of these are based on cellular connections, of which 0.2 billion are based on licensed Low Power Wide Area (licensed LPWA, a.k.a. LTE-M and NB-IoT) connections. 

Ericsson Mobility Report, June 2021, has a much more detailed breakdown regarding the numbers as can be seen in the slide above. As of the end of 2020, there were 12.4 billion IoT devices, of which 10.7 billion were based on Short-range IoT. Short-range IoT is defined as a segment that largely consists of devices connected by unlicensed radio technologies, with a typical range of up to 100 meters, such as Wi-Fi, Bluetooth and Zigbee.

Wide-area IoT, which consists of segment made up of devices using cellular connections or unlicensed low-power technologies like Sigfox and LoRa had 1.7 billion devices. So, the 1.6 billion cellular IoT devices also includes LPWAN technologies like LTE-M and NB-IoT.

Figures are connections/SIMs sold - not all will be live yet.

I also reached out to IoT experts at analyst firm Analysys Mason. As you can see in the Tweet above, Tom Rebbeck, Partner at Analysys Mason, mentioned 1.6 billion cellular (excluding NB-IoT + LTE-M) and 220 million LPWA (which includes NB-IoT, LTE-M, as well as LoRa, Sigfox etc.) IoT connections.

If I understand this correctly, as of June 2021 there were 1.55 billion cellular IoT connections. Do these include NB-IoT as well as LTE-M?

— Zahid Ghadialy (@zahidtg) October 2, 2021

I also noticed this interesting chart in the tweet above which shows the growth of IoT from Dec 2010 until June 2021. Matt Hatton, Founding Partner of Transforma Insights, kindly clarified that the number as 1.55 billion including NB-IoT and LTE-M.

As you can see, the number of cellular IoT connections are nowhere near 50 billion. Even if we include all kinds of IoT connectivity, according to the most optimistic estimate by Ericsson, there will be just over 26 billion connections by 2026.

Just before concluding, it is worth highlighting that according to all these cellular IoT estimates, over 1 billion of these connections are in China. GSMA's 'The Mobile Economy China 2021' puts the number as 1.34 billion as of 2020, growing to 2.29 billion by 2025. Details on page 9 here.

Hopefully, when someone wants to talk about Internet of Thing numbers in the future, they will do a bit more research or just quote the numbers from this post here.

Qualcomm Demoes Sub-band Half Duplex (SBHD)

Qualcomm has been busy promoting its advanced 5G solutions these last few months in the run up to Mobile World Congress (MWC). You can find a detailed write-up on their website here as well as a feature which they did with RCR wireless here.

One of the innovations that caught my attention was Sub-band Half-Duplex (SBHD). In the first glance it looks like the Enhanced Interference Mitigation & Traffic Adaptation (eIMTA) solution we discussed long back here.

Their article talks about how their 5G multi-cell over-the-air (OTA) test network can now support subband half-duplex, allowing for more flexible service multiplexing as well as improved latency and coverage. 

While you can get an idea of what SBHD is from the diagram above, here is a video explaining it further.

Let us know what do you think about how important will this feature be in future 5G networks.

Open RAN Terminology and Players

When we made our little Open RAN explainer, couple of years back, we never imagined this day when so many people in the industry will be talking about Open RAN. I have lost track of the virtual events taking place and Open RAN whitepapers that have been made available just in the last month.

One of the whitepapers just released was from NTT Docomo, just in time for MWC 2021. You can see the link in the Tweet

NTT Docomo has published 5G Open RAN Ecosystem (OREC) Whitepaper - https://t.co/17CJZuGnTT#Free5Gtraining #3G4G5G #4G #5G #NTT #NTTDocomo #OpenRAN #ORAN #OpenNetworks #Interfaces #Virtualization #Intelligence #TCO #IOT #Integration #RIC #Security #Performance #Deployment pic.twitter.com/1niHXnWr1v

Even after so much information being available, many people still have basic questions about Open RAN and O-RAN. I helped make an Open RAN explainer series and blogged about it here. Just last week, I blogged about the O-RAN explainer series that I am currently working on, here.

There were some other topics that I couldn't cover elsewhere so made some short videos on them for the 3G4G YouTube channel. The first video/presentation explains Open RAN terminology that different people, companies and organizations use. It starts with open interfaces and then looks at radio hardware disaggregation and compute disaggregation. Moving from 2G/3G/4G to 5G, it also explains the Open RAN approach to a decomposed architecture with RAN functional splits.

If you look at the Telecom Infra Project (TIP) OpenRAN group or O-RAN Alliance, the organizations driving the Open RAN vision and mission, you will notice many new small RAN players are joining one or both of them. In addition, you hear about other Open RAN consortiums that again include small innovative vendors that may not be very well known. 

The second video is an opinion piece looking at what is driving these companies to invest in Open RAN and what can they expect as return in future.

As always, all 3G4G videos' slides are available on our SlideShare channel.

5G Remote Surgery and Telehealth Solutions

One of the most controversial 5G use cases is the remote surgery. In this post I want to quickly look at the history and what is possible. Before I go to that, here is a short summary video that I am embedding upfront.



As far as I can recall, Ericsson was the first vendor that started talking about remote surgery. This is a tweet from back in 2017.

With #5G and the tactile internet, doctors can perform remote
surgery on a patient anywhere in the world. https://t.co/U81bayv3ws pic.twitter.com/pSXFg1NCJX

— Ericsson (@ericsson) August 28, 2017

Huawei didn't want to be far behind so they did one at MWC Shanghai in 2018. Their tweet with video is embedded below.

Meet the Remote Surgery Robot. At #MWCS18, Huawei stiches together a vivid picture of how #5G’s reliable connection can save lives: https://t.co/cobykl1KKP #WirelessXLabs pic.twitter.com/Pbme8BmcoT

— Huawei (@Huawei) June 28, 2018

In January 2019, South China Morning Post (SCMP) showed a video of a remote surgery on an animal. While the video and the article didn't provide many details, I am assuming this was done by Huawei as detailed here. The video of the surgery below.



This was followed by Mobile World Congress 2019 demo where a doctor used 5G to direct surgery live from a stage at MWC to Hospital Clinic Barcelona over 3 miles away. The team of doctors was removing a cancerous tumor from a patient's colon. This video from that is embedded below.



Vodafone New Zealand had a silly remote surgery of a dog video but looks like they have removed it.  Nothing can beat this Telecom Italia ad embedded below.



There are some realistic use cases. One of them being that with 5G the number of cables / wires in a hospital can be reduced saving on the disinfection.

NTT Docomo showcased 5G Mobile SCOT (Smart Cyber Operating Theater) which is an Innovative solution to enable advanced medical treatment in diverse environments. You can read more details here.

There are lots of other things going on. Here is a short list:

• April 2020: Because of Coronavirus COVID-19, NT Times has an article on Telemedicine Arrives in the U.K.: ‘10 Years of Change in One Week’ - even though this does not involve 5G, it just shows that we are moving in that direction.
• February 2020: 5G-aided remote CT scans used to diagnose COVID-19 patients in China (link)
• February 2020: Verizon teamed with Emory Healthcare to test new 5G use cases for the medical industry at the latter’s Innovation Hub in Atlanta, in a bid to discover how the technology can be used to improve patient care. The collaboration will explore applications including connected ambulances; remote physical therapy; medical imaging; and use of AR and VR for training. (link)

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:

IEEE 802.11be Extremely High Throughput (EHT) is the next generation of Wi-Fi Technology, beyond 802.11ax. One of the interesting enhancements will be that new tech will be able to work from 1GHz to 7.125 GHz. More in this paper: https://t.co/ESs95805d4 pic.twitter.com/QtTMJRHTZG

— 3G4G (@3g4gUK) April 20, 2019

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 touting it's broad portfolio of connected devices.

Distributed Massive MIMO using Ericsson Radio Stripes

One of the interesting things that caught my attention in MWC 2019 was the Ericsson Radio Stripes.

Emil Björnson explains it nicely in his blog as to how this works.

Distributed MIMO deployments combine the best of two worlds: The beamforming gain and spatial interference suppression capability of conventional Massive MIMO with co-located arrays, and the bigger chance of being physically close to a service antenna that small cells offer. Coherent transmission and reception from a distributed MIMO array is not a new concept but has been given many names over the years, including Distributed Antenna System and Network MIMO. Most recently, in the beyond-5G era, it has been called ubiquitous Cell-free Massive MIMO communications and been refined based on insights and methodology developed through the research into conventional Massive MIMO.

One of the showstoppers for distributed MIMO has always been the high cost of deploying a large number of distributed antennas. Since the antennas need to be phase-synchronized and have access to the same data, a lot of high-capacity cables need to be deployed, particularly if a star topology is used. 
...

For those who cannot attend MWC, further conceptual details can be found in a recent overview paper on Cell-free Massive MIMO. An even more detailed description of radio stripes can be found in Ericsson’s patent application from 2017.

The paper explains the Radio stripe system design and also lists the advantages of such a system:

The radio stripe system facilitates a flexible and cheap cell-free Massive MIMO deployment. Cheapness comes from many aspects: (i) deployment does not require highly qualified personnel. Theoretically, a radio stripe needs only one (plug and play) connection either to the front-haul network or directly to the CPU; (ii) a conventional distributed massive MIMO deployment requires a star topology, i.e., a separate cable between each APs and a CPU, which may be economically infeasible. Conversely, radio stripe installation complexity is unaffected by the number of antenna elements, thanks to its compute-and-forward architecture. Hence, cabling becomes much cheaper; (iii) maintenance costs are cut down as a radio stripe system offers increased robustness and resilience: highly distributed functionality offer limited overall impact on the network when few stripes being defected; (iv) low heat-dissipation makes cooling systems simpler and cheaper. While cellular APs are bulky, radio stripes enable invisible installation in existing construction elements as exemplified in Fig. below. Moreover, a radio stripe deployment may integrate for example temperature sensors, microphones/speakers, or vibration sensors, and provide additional features such as fire alarms, burglar alarms, earthquake warning, indoor positioning, and climate monitoring and control.

According to the Ericsson post:

One of the inventors and researchers behind the concept, Jan Hederén, Strategist at Ericsson 4G5G Development, says: 

"Although a large-scale installation of distributed MIMO can provide excellent performance, it can also become an impractical and costly "spaghetti-monster" of cables in case dedicated cables are used to connect the antenna elements.

To be easy to deploy, we need to connect and integrate the antenna elements inside a single cable. We call this solution the "radio stripe" which is an easy way to create a large scale distributed, serial, and integrated antenna system." Says, also inventors and researcher behind the concept."

This visionary concept is an extension of how to build and enhance the capability of current networks. The Radio Stripe systems offers, so to say, new colors and flavors in how we increase the performance of mobile networks.

The Radio Stripe vision is focused on improvements to the reach and quality of radio connectivity in the access part of the mobile network. It shares all other resources (transport, baseband, management, core) with current mobile solutions.

I am looking forward to reading a lot more about this kind of approach in the future and probably some deployment videos too.

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

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).

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.

Can Augmented & Mixed Reality be the Killer App 5G needs?

Last October Deutsche Telekom, Niantic and MobiledgeX announced a partnership to create advanced augmented reality experiences over mobile network technologies. I was lucky to find some time to go and play it at Deutsche Telekom booth. The amount of processing needed for this to work at best also meant that the new Samsung Galaxy S10+ were needed but I felt that it also occasionally struggled with the amount of data being transferred.

The pre-MWC press release said:

Deutsche Telekom, Niantic Inc., MobiledgeX and Samsung Showcase World’s First Mobile Edge Mixed Reality Multi-Gamer Experience

At the Deutsche Telekom booth at MWC 2019 (hall 3, booth 3M31) the results of the previously announced collaboration between Deutsche Telekom, Niantic, Inc., and MobiledgeX are on display and you’re invited to play. Niantic’s “Codename: Neon”, the world’s first edge-enhanced Mixed Reality Multiplayer Experience, delivered by ultra-low latency, Deutsche Telekom edge-enabled network, and Samsung Galaxy S10+ with edge computing enablement, will be playable by the public for the first time. 

“The ultra-low latency that Mobile Edge Computing (MEC) enables, allows us to create more immersive, exciting, and entertaining gameplay experiences. At Niantic, we’ve long celebrated adventures on foot with others, and with the advent of 5G networks and devices, people around the world will be able to experience those adventures faster and better,” said Omar Téllez, Vice-President of Strategic Partnerships at Niantic.

The collaboration is enabled using MobiledgeX’s recently announced MobiledgeX Edge-Cloud R1.0 product. Key features include device and platform-independent SDKs, a Distributed Matching Engine (DME) and a fully multi-tenant control plane that supports zero-touch provisioning of edge cloud resources as close as possible to the users. Immediate examples of what this enables include performance boosts for Augmented Reality and Mixed Reality (MR) experiences as well as video and image processing that meets local privacy regulations. 

Samsung has been working together with Deutsche Telekom, MobiledgeX, and Niantic on a natively edge-capable connectivity and authentication in Samsung Galaxy S10+ to interface with MobiledgeX Edge-Cloud R1.0 and dynamically access the edge infrastructure it needs so that augmented reality and mixed reality applications can take advantage of edge unmodified. Samsung will continue such collaborations with industry-leading partners not only to embrace a native device functionality of edge discovery and usage for the mobile devices and consumers, but also to seek a way together to create new business models and revenue opportunities leading into 5G era.

Deutsche Telekom’s ultra-low latency network was able to deliver on the bandwidth demands of “Codename: Neon” because it deployed MobiledgeX’s edge software services, built on dynamically managed decentralized cloudlets. “From our initial partnership agreement in October, we are thrilled to showcase the speed at which we can move from idea to experience, with full end-to-end network integration, delivered on Samsung industry leading edge native devices,” said Alex Jinsung Choi, Senior Vice President Strategy and Technology Innovation at Deutsche Telekom.

From the gaming industry to industrial IoT, and computer vision applications, consumer or enterprise, the experience is a great example of interactive AR experiences coming from companies like Niantic in the near future.  As AR/VR/MR immersive experiences continue to shape our expectations, devices, networks and clouds need to seamlessly and dynamically collaborate.

This video from Deutsche Telekom booth shows how the game actually feels like



Niantic CEO John Hanke delivered a keynote at Mobile World Congress 2019 (embedded below). According to Fortune article, "Why the Developer of the New 'Harry Potter' Mobile Game and 'Pokemon Go' Loves 5G":

Hanke showed a video of a prototype game Niantic has developed codenamed Neon that allows multiple people in the same place at the same time to play an augmented reality game. Players can shoot at each other, duck and dodge, and pick up virtual reality items, with each player’s phone showing them the game’s graphics superimposed on the real world. But the game depends on highly responsive wireless connections for all the phones, connections unavailable on today’s 4G LTE networks.

“We’re really pushing the boundaries of what we can do on today’s networks,” Hanke said. “We need 5G to deliver the kinds of experiences that we are imagining.”

Here is the video, it's very interesting and definitely worth a watch. For those who may not know, Niantic spun out of Google in October 2015 soon after Google's announcement of its restructuring as Alphabet Inc. During the spinout, Niantic announced that Google, Nintendo, and The Pokémon Company would invest up to $30 million in Series-A funding.



So what do you think, can AR / MR be the killer App 5G needs?

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!

An Introduction to ONF and CORD (Central Office Re-architected as a Datacenter)

Continuing on the theme of Open Source from last week's post from Telefonica, lets look at the CORD by ONF.

The CORD (Central Office Re-architected as a Datacenter) platform leverages SDN, NFV and Cloud technologies to build agile datacenters for the network edge. Integrating multiple open source projects, CORD delivers a cloud-native, open, programmable, agile platform for network operators to create innovative services.

CORD provides a complete integrated platform, integrating everything needed to create a complete operational edge datacenter with built-in service capabilities, all built on commodity hardware using the latest in cloud-native design principles.



The video above from MWC 2018 is a very short summary of what ONF and CORD is. The video below from OCP Telecom Workshop at the Big Communications Event (BCE) on May 14th, 2018 in Austin, Texas looks at CORD in detail.

LoRa is quietly marching on...

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. #MWC18 pic.twitter.com/KQ6G7JjTU9

To start with, lets look at this short report by Tom Rebbeck from Analysys Mason. The PDF can be downloaded after registering from here.

As can be seen, all major IoT technologies (LoRa, NB-IoT, Sigfox & LTE-M) gained ground in 2017. Most of the LoRa and all of Sigfox networks are actually not deployed by the mobile operators. From the article:

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:

Here is a short video from MWC by yours truly looking at LoRa Gateways


There are also few announcements / news from LoRa world just to highlight how the ecosystem is thriving:

• Successful international roaming test between Orange and KPN LoRaWAN™ networks with Actility opens new horizons for IoT business applications
• European LoRa roaming by year-end, as network deployments double
• MTN Business announces dedicated IoT network using LoRaWAN and NarrowBand-IoT
• Semtech and Lacuna Sending LoRaWAN Messages from Space
• Kazakhtelecom builds largest Internet of Things network in CIS utilising LORA, Zigbee and LTE technologies

Source: SenRa

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.

LoRaWAN and 3GPP technologies cover all Industrial IoT use cases from Actility

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.
