Innovations from the left field of Mobile World Congress 2019

Innovations demonstrated at a fringe event outside of the sound and fury of MWC showed promise to solve some real-life problems.

MobileFocus, a long-running fringe event during the MWC week in Barcelona, brought about two dozen companies to showcase their innovations that may not hit the frontpage but are illuminating nonetheless. There were big companies, like Lenovo, which displayed a slew of its new PCs, but most exhibitors are single product small companies. Some of them promoted ideas as straightforward as Bluetooth speakers focused on design, or water-proof cases to take smartphones into the pool. Others are trying to address more sophisticated issues. At least three of them impressed.

MobileFocus Amber

Amber is an elegant looking private cloud datacentre. It is also a high-speed Wi-Fi router and in-home media casting centre (with DLNA), and other functions. This product would appeal to the users that are interested in saving their files in the cloud but are concerned with the security of public clouds (e.g. iCloud, which has been compromised in some high-profile cases). With this device physically located in the user’s own premise, hacking would become more difficult. It also has strong enough processing power (an Intel Dual-Core CPU) and embedded AI engine, so it can also do facial indexing and searching as the Google Photos offers. Trusted parties can also remotely (i.e. outside of the home environment) access files on the datacentre. Coming up next, the company will offer passive back-up on the company’s cloud, as a double security. By passive back-up, the company explained, it meant the files cannot be shared from the cloud. The California-based start-up expects the products to hit the market in the next month.

MobileFocus e-checkup

e-Checkup is designed to measure a user’s blood pressure with a set of sensors added on the back of a smartphone and the application to go with it. Although the wellness functions on smartphones and smartwatches will measure pulses, very few have offered blood pressure measuring, presumably because it is harder to get right. The company claimed that this is the world’s first accurate cuff-less and calibration-free blood pressure measurement system. The application gamifies the measuring processes by asking the user to keep pressing against the sensors to keep an on-screen water stream steadily pouring into a lake. Readings will be made when the water level rises to a defined bar. The Lausanne-based Leman Micro Devices expected that this technology could be cleared by the FDA for a Class II risk device category soon. That would be the same class as the latest Apple Watch. It is also in advanced discussions with unnamed smartphone OEMs to integrate the sensors in their upcoming phone models to make the testing experience more ergonomically pleasant (the mock-up on the top of the picture).

MobileFocus DeviceAssure fake Galaxy 9

DeviceAssure is a B2B security tool to detect counterfeit mobile devices. The service offered by the Dublin-based company can run both on-device and cloud-based test of the product down to chipset level to decide whether it is genuine. Three new “developments” in the counterfeit trade have made the detection job both more challenging and more pertinent. Counterfeiting techniques are much more advanced. This “Galaxy 9” looks very bit the part except that it is a $80 fake, and an ordinary user would find it hard to tell with his naked eyes.

Distribution is more efficient, helped by the online shopping channels. Last but not the least, the bloatware or even malware preinstalled on these phones are more sophisticated. The last of the three new trends makes it particularly desirable for the company’s corporate customers to be more vigilant against counterfeit end user devices. For example, corporate IT teams need to be able to block counterfeit devices from connecting to the corporate networks to defend against malware being distributed; or banks should be able to stop counterfeit handsets installing online banking applications as their customers’ security could be more easily compromised. The company representatives did admit, however, that it took them a while to understand why, out of all kinds of enterprise customers, telecom operators were the least concerned with counterfeit phones, so long as the users pay the phone bills.

Some of the companies also have a booth inside MWC, but most of them only attend fringe events like this. A few companies at MobileFocus also ride on the big themes like IoT security, but most of them start with solving a more concrete problem, which makes the fringe events more refreshing. Edinburgh Fringe has given us Stephen Fry, might MWC fringe give us tomorrow’s Steve Jobs?

Almost one zettabyte of mobile data traffic in 2022 – Cisco

Cisco forecasts that 5G connections will go from nothing in 2017 to 3.4% of the global total in 2022. Over the same period annual mobile data traffic will reach 930 exabytes, a seven-fold growth.

The report provides plenty of valuable data points for the industry, both of records of recent history and predictions of the near future. For example, despite the expected fast growth of 5G, by 2022, 4G will continue to dominate both the number of connections and the data generated. 54% of total connections will be on 4G, which will generate 71% of total mobile data traffic. Mobile data traffic will represent 20% of all IP traffic by 2022.

With regard to data traffic by individual devices, on average a smartphone will generate 11 GB of traffic per month by 2022, up from 2GB in 2017. Mobile video will be responsible for even higher proportion of the total traffic. 59% of the total mobile data was video in 2017. This number will grow up to 79% by 2022, and the absolute data volume of mobile video will increase by nine times.Cisco VNI monthly data volume

The report identifies seven key global mobile networking trends, from Cisco’s perspective.

  1. Evolving toward Smarter Mobile Devices: this largely refers to the high and increasing percentage of smartphones, including phablets, in all the connected devices (from 50% to 54%), as well as the fast growth of M2M connections (from 11% to 31%). Main segment losing out will be non-smartphones (from 34% to 10%).
  2. Defining Cell Network Advances: this trend refers to the accelerated growth of mobile connections on newer technologies (4G and 5G) in contrast to the fast decline of the number of 2G connections and the gradual decline of 3G connections. Another fast-growing segment is M2M on Low-Power Wide-Area (LPWA) networks, increasing from 130 million in 2017 to 1.8 billion by 2022. Cisco VNI connections by technology
  3. Measuring Mobile IoT Adoption: captured in this trend is the continued growth of M2M and wearable connections. Globally, M2M connections will grow from just under 1 billion in 2017 to 3.9 billion by 2022, a CAGR of 32%. Wearables are treated as a subset of M2M connections by Cisco. The report forecasts 1.1 billion wearable devices globally by 2022, more than double the volume of 526 million in 2017, with a CAGR of 16%. Among them, 10% will have embedded cellular connectivity, up from 4% in 2017.
  4. Expanding Role and Coverage of Wi-Fi: the volume of mobile data may be big, but the volume of mobile data going through Wi-Fi offload is even bigger. The report forecasts that 59% of all data from mobile connected devices will be offloaded to Wi-Fi in 2022, amounting to 111.4 exabytes per month, up from 54% offload, or 13.4 exabytes per month in 2017. To enable the fast growth of offload data volume, the report forecasts, there will also need to have much more Wi-Fi hotspots. It estimates that Wi-Fi hotspots (including homespots) will grow from 124 million in 2017 to 549 million by 2022.
  5. Identifying New Mobile Applications and Requirements: in addition to video being the application category that generates the lion’s share of total mobile data traffic, VR, AR and Mixed Reality are also expected to experience a fast growth in the coming years. Globally, augmented and virtual reality traffic will grow from 22 petabytes per month in 2017 to 254 petabytes per month in 2022.
  6. Comparing Mobile Network Speed Improvements: the speed of mobile data is determined by both the networks and devices. In particular with the accelerated 5G rollout in the forecast period, the report expects to see the average speed of mobile network connection to increase from 8.7 Mbps in 2017 to 41.6 Mbps in 2022. The speeds also vary vastly between technologies. While the average 4G speed is expected to grow from 30 Mbps in 2017 to 44 Mbps in 2022, the average 5G speed will increase from 76 Mbps in 2019 to 170 Mbps in 2022. Cisco VNI speed by technology
  7. Reviewing Tiered Pricing, Unlimited Data and Shared Plans: the final trend examines what impact operators’ data packages and tiered pricing schemes will have on customers’ data consumption patterns. One interesting finding is that, a combined effect of all users increasing their data usage and more operators reintroducing data package cap has driven the proportion of data generated by the top 1% of users down from 52% in 2010 to only 6% in 2018.

The Visual Networking Index is produced by combining Cisco’s proprietary data and assumptions with that published by professional research firms as well as by the ITU.

Are you ready to look at 6G?

We can hear the groans already, but we’re going to do it anyway. Let’s have a look at what 6G could possibly contribute to the connected economy.

Such is our desire for progress, we haven’t even launched 5G but the best and brightest around are already considering what 6G will bring to the world. It does kind of make sense though, to avoid the dreaded staggering of download speeds and the horrific appearance of buffering symbols, the industry has to look far beyond the horizon.

If you consider the uphill struggle it has been to get 5G to this point, and we haven’t even launched glorious ‘G’ properly, how long will it take before we get to 6G? Or perhaps a better question is how long before we actually need it?

“5G will not be able to handle the number of ‘things’ which are connected to the network in a couple of years’ time,” said Scott Petty, CTO of Vodafone UK. “We need to start thinking about 6G now and we have people who are participating in the standards groups already.”

This is perhaps the issue which we are facing in the future; the sheer volume of ‘things’ which will be connected to the internet. As Petty points out, 5G is about being bigger, badder and leaner. Download speeds will be faster, reliability will be better, and latency will be almost none existent, but the weight of ‘things’ will almost certainly have an impact. Today’s networks haven’t been built with this in mind.

Trying to find consensus on the growth of IOT is somewhat of a difficult task, such is the variety of predictions. Everyone predicts the same thing, the number of devices will grow in an extra-ordinary fashion, but the figures vary by billions.

Using Ericsson’s latest mobility report, the team is estimating cellular IoT connections will reach 4.1 billion in 2024, of which 2.7 billion will be in North East Asia. This is a huge number and growth will only accelerate year-on-year. But here is thing, we’re basing these judgments on what we know today; the number of IOT devices will be more dependent on new products, services and business models which will appear when the right people have the 5G tools to play around with. Who knows what the growth could actually be?

IOT Growth

Another aspect to consider is the emergence of new devices. As it stands, current IOT devices deliver such a minor slice of the total cellular traffic around the world its not much of a consideration, however with new usecases and products for areas such as traffic safety, automated vehicles, drones and industrial automation, the status quo will change. As IOT becomes more commonplace and complicated, data demands might well increase, adding to network strain.

Petty suggests this will be the massive gamechanger for the communications industry over the next few years and will define the case for 6G. But, who knows what the killer usecase will be for 5G, or what needs will actually push the case for the next evolution of networks. That said, more efficient use of the spectrum is almost certainly going to be one of the parameters. According to Petty, this will help with the tsunami of things but there is a lot of new science which will have to be considered.

Then again, 6G might not be measured under the same requirements as today…

Sooner or later the industry will have to stop selling itself under the ‘bigger, badder, faster’ mantra, as speeds will become irrelevant. If you have a strong and stable 4G connection today, there isn’t much you can’t do. Few applications or videos that are available to the consumer require 5G to function properly, something which telco marketers will have to adapt to in the coming years as they try to convince customers to upgrade to 5G contracts.

4G and arguably todays vision of 5G has always been about making the pipe bigger and faster, because those were the demands of the telcos trying to meet the demands of the consumer. 6G might be measured under different KPIs, for example, energy efficiency.

According to Alan Carlton, Managing Director of InterDigital’s European business, the drive towards more speed and more data is mainly self-imposed. The next ‘G’ can be defined as what the industry wants it to be. The telcos would have to think of other ways to sell connectivity services to the consumer, but they will have to do that sooner or later.

The great thing about 5G is that we are barely scratching the surface of what is capable. “We’re not even at 5.0G yet,” said Carlton. “And this is part of the confusion.”

What 5G is nowadays is essentially LTE-A Pro. We’re talking about 256-QAM and Massive MIMO but that is not really a different conversation. With Release 16 on the horizon and future standards groups working on topics such virtualisation, MMwave and total cost of ownership, future phases of 5G will promise so much more.

The next step for Carlton is not necessarily making everything faster, or more reliable or lower latency, but the next ‘G’ could be all about ditching the wires. Fibre is an inflexible commodity, and while it might be fantastic, why do we need it? Why shouldn’t the next vision of connectivity be one where we don’t have any wires at all?

Carlton’s approach to the future of connectivity is somewhat different to the norm. This is an industry which is fascinated by the pipes themselves and delivering services faster, but these working groups and standards bodies are driving change for the benefit of the industry. It doesn’t necessarily have to be about making something faster, so you can charge more, just a change to the status quo which benefits the industry.

Coming back to the energy efficiency idea, this is certainly something which has been suggested elsewhere. IEEE has been running a series of conferences in California addressing this very issue, as delivering 1000X more data is naturally going to consume more energy to start with. It probably won’t be 1000X more expensive, but it is incredibly difficult to predict what future energy consumption needs will be. Small cells do not consume as much energy as traditional sites, but there will need to be a lot more of them to meet demand. There are a lot of different elements to consider here (for example environment or spectrum frequency), but again, this is a bit of an unknown.

Perhaps this is an area where governments will start to wade in? Especially in the European and North American markets which are more sensitive to environmental impacts (excluding the seemingly blind Trump).

Echoing Petty’s point from earlier, we don’t necessarily know the specifics of how the telco industry is going to be stressed and strained in six- or seven-years’ time. These changes will form the catalyst for change, evolving from 5G to 6G, and it might well be a desire for more energy efficient solutions or it might well be a world free of wires.

Moving across the North Sea, 6G has already captured the attention of those in the Nordics.

Back in April 2018, the Academy of Finland announced the launch of ‘6Genesis’, an eight-year research programme to drive the industry towards 6G. Here, the study groups will start to explore technologies and services which are impossible to deliver in today’s world, and much of this will revolve around artificial intelligence.

Just across the border in Sweden, these new technologies are capturing the attention of Ericsson. According to Magnus Frodigh, Head of Ericsson Research, areas like Quantum computing, artificial intelligence and edge computing are all making huge leaps forward, something which will only be increased with improved connectivity. These are the areas which will define the next generation, and what can be achieved in the long-run.

“One of the new things to think about is the combination of unlimited connectivity as a resource, combined with low latency, more powerful computing,” said Frodigh. “No-one really knows how this is going to play out, but this might help define the next generation of mobile.”

Of course, predicting 6G might be pretty simple. In a couple of years’ time, perhaps we will all be walking around with augmented reality glasses on while holographic pods replace our TVs. If such usecases exist, perhaps the old ‘bigger, badder, faster’ mantra of the telco industry will be called upon once again. One group which is counting on this is EU-funded Terranova, which is currently working on solutions to allow network connection in the terahertz range, providing speeds of up to 400 Gbps.

Another area to consider is the idea of edge computing and the pervasiveness of artificial intelligence. According to Carlton (InterDigital), AI will be every in the future with intelligence embedded in almost every device. This is the vision of the intelligent economy, but for AI to work as promised, latency will have to be so much lower than we can even consider delivering today. This is another demand of future connectivity, but without it the intelligent economy will be nothing more than a shade of what has been promised.

And of course, the more intelligence you put on or in devices, the greater the strain on the components. Eventually more processing power will be moved off the devices and into the cloud, building the case for distributed computing and self-learning algorithms hosted on the edge. It is another aspect which will have to be considered, and arguably 5G could satisfy some of these demands, but who knows how quickly and broadly this field will accelerate.

Artificial intelligence and the intelligent economy have the potential to become a catalyst for change, forcing us to completely rethink how networks are designed, built and upgraded. We don’t know for sure yet, but most would assume the AI demands of the next couple of years will strain the network in the same way video has stressed 4G.

Who knows what 6G has in store for us, but here’s to hoping 5G isn’t an over-hyped dud.

Nike has made some shoes that you can lace up with your smartphone

The dark days of having to tie your shoelaces manually may finally be behind us thanks to the latest innovation from trainer-maker Nike.

It’s all down to the advanced power-lacing system in the Nike Adapt BB you see, coupled with some firmware and an app. The shoe actually has a motor and gear train, apparently, which are able to impart no less than 32 pounds of force through the underfoot lacing, as shown below.

Nike adapt bb 3

But that’s not the half of it. “That’s where the brain, or FitAdapt tech, kicks in,” effuses the Nike press release. “By manual touch or by using the Nike Adapt app on a smartphone, players can input different fit settings depending on different moments of a game. For example, during a timeout, a player can loosen the shoe before tightening it up as they re-enter the game.

“In a forthcoming feature, they can even prescribe a different tightness setting for warm-ups. Plus, players can opt in to firmware updates for the FitAdapt technology as they become available, sharpening the precision of fit for players and providing new digital services over time.”

Nike adapt bb 2

This is all wonderfully utopian and anticipated by a clever piece of Nike product placement back in 1989 in the film Back to the Future 2, as shown below. It’s also, of course, one of the best examples of solving first-world problems you’ll ever see. Nonetheless Nike will get some cool marketing out of this and judging by this comprehensive TechCrunch review, some tech kudos too. Can you imagine what a pair would cost though?

Giesecke+Devrient lands Swatch contactless payment gig

Mobile security company Giesecke+Devrient is helping Swiss watch company Swatch with its own contactless payment technology.

Rather annoyingly called SwatchPAY!, the contactless platform was launched in China back in 2017 and is now available in Switzerland. It involves sticking an NFC chip in a watch, which you can then sync with your credit card. In that respect it’s pretty much a contactless card embedded in a watch.

Whether it functions just as easily is unclear, but Swatch seems to have partnered with all the right companies, including Mastercard, Credis Suisse, UBS and G+D. The latter is doing what it does best in providing the secure element for these watches, which also enables the activation of the contactless payment function in-store, when you buy one. Here’s how it works.

Swatchpay chart

“Continuous innovation is a key strand of the Swatch DNA,” said Carlo Giordanetti, Swatch Creative Director. “This latest advance, with the introduction of the fastest and simplest tokenization, makes it easier than ever to pay ‘forever’ – token up your Swatch, swipe it and you’re done. SwatchPAY! is simple, stylish and swatchy.”

“We are thrilled to be Swatch’s partner for this payment-enabled watch, which has been a huge success in China,” said Carsten Ahrens, CEO of Giesecke+Devrient Mobile Security. “The unique mix of iconic Swatch design and a payment functionality makes this a very appealing product, and we are proud to have contributed our extensive expertise in security, mobile payment and wearables technology.”

The Swiss watch industry has been in a flap about smart watches for a while, so it’s sensible to see one of them develop its own contactless payment platform. They’re fortunate that the killer use-case for smart watches hasn’t been found yet, but it presumably will be eventually. The key to this alternative being a success will be its ease of setup and use and it looks like they might have got that right.

Xiaomi unveils new strategy stressing AI, IoT and smartphones

The Chinese device maker Xiaomi has announced its new strategy will be built around two core areas: smartphone and AI+IoT.

At the company’s annual party, Lei Jun, Xiaomi’s founder and CEO, pledged an investment of CNY 10 billion ($1.5 billion) over the next five years, in a strategy it calls AIoT (meaning both “AI+IoT” and “All in IoT”). The objective is to develop this part of the business into a second core of the company’s strategy, to dovetail with its current core business: smartphones.

Xiaomi is no stranger to artificial intelligence. AI has been in the centre of Xiaomi’s marketing messages for its photo technologies on the new smartphones and the smart speakers. Nor has it been a novice in IoT. In fact, Xiaomi claims to be the world’s largest IoT company, “connecting more than 132 million smart devices (excluding mobile phones and laptops), including more than 20 million daily active devices as of September 30 (2018).” This mainly comes in its smart home category including products ranging from smart suitcases to smart scooters and everything in between.

Smartphone, on the other hand, has always been the linchpin in Xiaomi’s ecosystem. After its fast growth in China and the rapid market share gain in emerging markets like India, Xiaomi recently expanded into Europe, including choosing to debut its latest flagship smartphone in London. Additionally, Xiaomi sees in Latin America new growth opportunites. It is also one of the smartphone OEMs to endorse Qualcomm’s 5G chipset. However, as Lei recognised, “Before the proliferation of 5G technology, Xiaomi’s success in smartphone business segment lies in striving to consolidate its leading position in the smartphone markets across the world.”

As a means to continue strengthening its smartphone positions, Xiaomi also announced a dual-brand strategy. Its flagship and other high-end products will continue to come under the “Mi” brand, while the mid-range value-for-money products will carry the “Redmi” brand. Here Xiaomi may have taken a page from Huawei’s brand strategy, which has used “Honor” to address the mid-range segment while its flagship products have been branded “Huawei” and come in Mate or Pro series.

Nokia and StarHub boast of completed 5G NR trial Singapore

Nokia and the Singapore mobile operator StarHub conducted an outdoor pilot of both industrial and consumer use cases on 5G New Radio (NR).

The two companies made another claim for Singapore’s “5G first” drive with this outdoor 3GPP compliant trial on 3.5 GHz. Two use cases were demonstrated to their staff, industry partners, and enterprise customers. The first one for industry was a simulated manufacturing environment, where businesses can use 5G-based video analytics to optimise efficiency and reduce errors. The use case for consumers was a 5G-based VR immersive video experience of live sport events. The trial was done in non-standalone (NSA) mode, with Nokia’s 5G AirScale radio access overlaying on top of StarHub’s 4G core networks. The third-party that supplied the consumer VR terminals has not been identified.

“This successful pilot with Nokia showcases the readiness and possibilities of 5G to enhance consumer services and boost efficiencies for enterprises. It aligns with StarHub’s goal to support and accelerate Smart Nation initiatives in Singapore,” said Chong Siew Loong, Chief Technology Officer of StarHub.

“Nokia is able to offer customers such as StarHub a pre-integrated and ultra-optimised network using its 5G Future X end-to-end architecture to accelerate the launch of 5G. Leveraging this technology, customers such as StarHub can achieve greater operational efficiencies and higher performance as they begin to deliver enhanced mobile broadband services,” added Tommi Uitto, president of Mobile Networks at Nokia.

Singapore is expected to be among the first countries to switch on commercial 5G networks. With its competitor Singtel busy trialling 5G and claiming its own “firsts”, StarHub must have felt the heat to not to be seen left behind. as industry momentum towards 5G NR is gathers momentum. After more than 40 companies signed the agreement in March 2017 to accelerate 5G NR development, much progress has been made on both the standardisation and the implementation fronts. Both the standalone (SA) and non-standalone variants of the 5G NR standards were completed and approved before the original deadlines.

Vodafone pulls out a genuinely good 5G demo – get ready for holograms!

While many 5G demos show technical progress, few wow an audience in the same way Vodafone did at its Future Ready press conference, unveiling the UK’s first live holographic call.

After CTO Scott Petty set the stage with a number of impressive announcements indicating Vodafone is perhaps not the cumbersome beast we have come to expect, an underwhelming skit involving a VR headset and England Women’s football captain Steph Houghton led irritable journalists towards a slumber. But with a drop of the curtain, the demo was unveiled in all its glory. And it was incredibly impressive.

5G will enable remote surgery and 4K gaming experiences, though there is little excitement generated through this announcements nowadays. Using 5G technology to underpin the experience, Houghton, who was located in a Manchester studio at the time, appeared in Vodafone’s Newbury HQ as a 3D hologram. The image was sharp, the lag was unnoticeable and all of a sudden the audience was engaged. It was cheesy, as Houghton showed off her skills and answered some questions from 11 year-old football fan Iris, but it was an excellent demonstration of the power of 5G.

“Vodafone has a history of firsts in UK telecoms – we made the nation’s first mobile phone call, sent the first text and now we’ve conducted the UK’s first holographic phone call using 5G,” said Vodafone UK CEO Nick Jeffrey.

What is worth noting is this is not a world first, KT is developing hologram calling as a flagship 5G service and has conducted a test call between Verizon CEO Lowell McAdam and its own CEO Hwang Chang-gyu. That said, this should not take the shine off an impressive demonstration.

Some might look at such an idea and scoff; what is the opportunity aside from showing off what the network is capable of, surely this isn’t realistic for the real world? But why not?

A decade ago it would have been inconceivable to consider video conferencing as a mass market product. In the early years it was reserved for the board room, due to the price of equipment and the software to make it work. Nowadays, Skype calling is as common as a sausage sandwich. We’re not suggesting hologram calling is going to be commonplace over the next couple of years, but who knows what is possible when the price point of technology starts tumbling down.

CTO Petty referred to the famous Bill Gates quote when discussing the potential for a mass market product; most people overestimate what they can do in one year and underestimate what they can do in ten. The mind runs wild when you consider what could be possible; GP consultations from your living room, distance learning would take on a new spin and some sports events, boxing for instance, could take the live audience from tens of thousands to millions by setting up holographic arenas all over the world. Healthcare, education and entertainment could be completely revolutionised.

It’s been a while since a 5G demonstration has genuinely got a room full of journalists excited; well done Vodafone!

 

The FDA certified Apple Watch is still not a medical device

The new Apple Watch has been cleared by the FDA to sell as a low-grade health tracking device but is not producing medical grade data.

At the event where the new iPhones were launched, Apple also launched the 4th iteration Apple Watch. Though it was not the focus of the event, Apple deservedly prided itself for being the first smart watch to pass FDA test. One feature highlighted at the presentation is, by combining the readings from the gyroscope and the accelerometer the Watch can tell when a user has tripped or fallen. If the user stays static after the fall for more than a minute, the cellular equipped Watch can automatically call for help from emergency service or reach out to the family or friend. This can turn out very helpful for the aging population.

Another function of the Apple Watch being marketed is its capability to detect and alert the user irregular heartbeats which can be a symptom of a heart condition called atrial fibrillation, or AFib. This can also be a meaningful feature for a large user group: according to estimates by the US Centers for Disease Control, between 2.7 and 6.1 million people in the US have AFib, many of whom may not be even aware of it.

Apple has conducted an “Apple Heart Study” with Stanford University, the findings of which became the basis on which it gained the FDA clearance. However the total sample size was small (few than 600) and the match rate with professional medical devices was not extremely high. But the data was good enough to convince FDA that the solution worked and it was safe. Apple Watch was given a Class II risk device category, meaning it will not be life threatening even if it does not work. In contrast, if a pacemaker stops working the patient will die, therefore it is classified Class III.

In its approval file to Apple, the FDA demanded Apple to explicitly spell out the possibility of inaccurate reading as well as warn users that the is not a replacement for medical care, although the worst that can happen when the Watch reading is wrong is to cause scare for a healthy user.

Therefore, the new Apple Watch can do the job of a low to mid-range electrocardiogram reader, but it is not a medical device. In a typical professional situation, a patient will have 12 reading leads attached to different parts of the body, including the chest and the limbs, to provide accurate reading. What Apple Watch can give is equivalent to one of them, on the wrist.

No professional physicians will make judgement based on the reading on the Apple Watch. Any sensible users had better not either.
