This year’s Mobile World Congress in Barcelona has been cancelled after mass cancellations from exhibitors worried about the coronavirus. GSMA, the organising body pulled the plug on Wednesday, two weeks before the event was due to begin. Before GSMA acted big names such as Cisco, Nokia, Vodafone group and Facebook all dropped out.
The Financial Times (behind a paywall) reports:
The conference’s cancellation will be a big blow for Barcelona, where hotels and restaurants ramp up prices in expectation of a bumper week that attracts high-spending telecoms executives. Local media has estimated that it generates €492m for the city, and creates about 14,000 temporary jobs.
This makes a lot of sense. MWC is a huge four day event, more than 100,000 people from all over the world attend. Many are from China where the virus is most prevalent. Last year the organisers boasted there were more than 1 million business meetings at the event.
If only one of those people tested positive for the virus, all the attendees would need to be quarantined for two weeks. Apart from anything else, the expense and logistics of that would be on an unprecedented scale.
Apart from the financial risk, the danger for GSMA is that cancelling this year’s MWC could put next year’s event in jeopardy. But let’s not dismiss that financial risk, the show’s insurers appear unwilling to pay out for cancellation.
Samsung is on its second generation of foldable phones. Motorola and Huawei are a step behind, but remain in the game. Will your next phone be one you can fold?
The technology is impressive. All the foldable phones I’ve seen to date look great. They are also useful.
Folding means a handheld phone can morph into a small iPad Mini sized tablet. They make reading and simple online tasks easier than on everyday phones.
From a phone maker perspective they do three important things.
First, they give phone buyers a reason to upgrade. People have been hanging on to phones for longer because there is less pressing reason to upgrade. Adding a new functionality breaks that cycle.
Out of the cul-de-sac
Second, they give phone makers a route of the design cul-de-sac.
Phone formats have stabilised as slabs of glass and metal. They would be almost featureless if it were not for the ever swelling camera bumps. Makers add more lenses and more receptor pixels in a bid to competitive1.
Folding phones open up new ways to differentiate and compete.
The third benefit of folding phones for phone makers is they sell for premium prices. Phone makers can increase the average unit price at a time of intense competition downward pressure on prices.
Phone makers announced two more foldable models in the last week or so. Samsung’s Galaxy Z Flip and Lenovo’s $1,500 Motorola Razr are both flip phones with folding screens.
Foldables have not got off to a good start. Samsung’s Galaxy Fold was a botched launch. A second wave of models was better, but they are still fragile and expensive at NZ $3400.
The Motorola Razr is as fragile and has poor battery life.
In other words, the models we’ve seen so far are undercooked. They will sell to well-heeled early adopters. These people will pay a king’s ransom to act as guinea pigs. Meanwhile the phone makers can go back to the drawing board and perfect their designs.
They will make it into the mainstream in one of two ways. Either Apple will create a folding iPhone that gets the technology right and resets the market or Samsung will brute force its way to success. The other possibility is that folding phones go the way of 3D television sets.
There’s no doubt this is a development worth watching. My advice is to hang on to your money for now, maybe squeeze another year from your existing phone. The benefits of having a bigger screen are not enough to outweigh the risk of spending a lot of money on something that’s easy to break.
It’s questionable this is what most buyers want. ↩︎
Research by two psychology professors sifted through 40 studies examining links between social media use, adolescent depression and anxiety. They conclude the link is “small and inconsistent”.
In other words this isn’t about phones, it’s about social media. Phones are what people in the computer security business call the attack vector.
Earlier research published in the American Academy of Pediatrics in 2011 suggests there is a link between Facebook and depression. That was later revised.
Since then here have been many similar high profile reports. One researcher linked social media to teen suicide.
“There doesn’t seem to be an evidence base that would explain the level of panic and consternation around these issues,” said Candice L. Odgers, a professor at the University of California, Irvine, and the lead author of the paper, which was published in the Journal of Child Psychology and Psychiatry.”
“The debate over the harm we — and especially our children — are doing to ourselves by staring into phones is generally predicated on the assumption that the machines we carry in our pockets pose a significant risk to our mental health.”
With academics you have to take note of all the words. Odgers talks of ‘significant risk’. That doesn’t mean there is no risk. Her point is that the panic is overdone. That doesn’t mean we can ignore the risks.
Odgers says: “In most cases, they say, the phone is just a mirror that reveals the problems a child would have even without the phone.”
This is true. But do phones, or social media, reveal or amplify the problems?
While this story may make sense from an academic psychiatry point of view, there’s another dimension. We know social media outlets and their advertisers manipulate emotions because they have admitted as much and, in some cases, promised to improve future behaviour.
So by all means dial down your concerns about children and phones, but don’t wash your hands of the matter. There are things to worry about, they just are not as bad as excitable commentators would have you think.
This meant Google suspended its business with Huawei. That was a blow for the Chinese phone maker, Huawei phones run on Google’s Android software.
The ban goes beyond Android. It means Huawei phones can’t use the Play app store. Nor can they use Google Maps, Gmail or the official Search app. Google Mobile Services features are central to the Android phone experience.
Huawei makes some of the best Android phones. It has a huge market share, now second only to Samsung. Yet the company sells little in the US.
With Huawei phones unable to ship with Google apps installed, sales have fallen outside China.
Otherwise, Huawei appears to be in good shape. In October it announced revenues were up 24 percent on the previous year. The company signed 60 contracts to build 5G networks last year.
Huawei could sit out the ban. Many think it is as much about US trade protectionism as anything to do with security.
Subscribers to this school of thought believe the US could lift the Huawei ban as part of trade negotiations.
While that is plausible, Huawei never wants to be in this position again. It cannot afford to be dependent on Google when the US could turn off the tap again at any moment.
Huawei has offered Chinese customers a non-Google version of its phones for years. It isn’t a problem there. It is more of an issue in places like New Zealand, Australia and Europe where people rely on Google services.
To get around the ban, Huawei is replacing Google Mobile Services with its own services. It aims to spend US$ 3 billion this year getting developers to improve Huawei Mobile Services. It has set aside another billion to market those services.
Harmony in my head
Huawei is also developing its own Harmony OS. It scheduled release for early this year. Now Huawei says it is running late and could take years to emerge.
The acid test for Huawei’s post-Google life is the P40 phone launch. It will have no Google services. Huawei expects to lose some market share.
The original plan was to launch in March. This could be set-back by the recent coronavirus outbreak.
Joining Huawei are Oppo, Vivo and Xiaomi. For now, the other Chinese phone makers are not locked out of Google. Yet the move amounts to admission they fear the ban could extend to them.
Between them, the four account for 40 percent of handsets sold worldwide. Yet for now they restrict their project to nine regions including India, Indonesia, Malaysia and Russia.
It is still early days. Yet it seems the US ban on Huawei is speeding up Chinese tech companies becoming independent of US ones. They already buy less American hardware, software and services. Google and Android remain strong, but one outcome of the ban is to undermine the near monopoly.
Can you get cancer or other illnesses from cellphones? What about Wi-Fi networks? Are there 5G health risks?
The answer is a definitive no. There are no ifs and buts. Wireless communications pose no health risks.
How can we so certain there is no problem?
The first answer is that wireless networks have been widespread for 30 years now. Over that time many scientists have researched the subject. They have found a heating effect from high power wireless equipment. But that’s not used for communications. We’ll come back to this later.
Conspiracy theorists suggest scientists and governments suppress bad results. They don’t. As you will see if you read on, we can be sure of this.
This brings us to the second reason why we know wireless is safe. There are no queues of patients showing up at hospitals with cellphone cancer. The technology has had 30 years to do its worst and still there are no signs of an epidemic.
It’s not hard to understand why there are conspiracy theories. Governments and industries have lied to people in the past.
Its’s also not hard to understand why radiation seems frightening. There are harmful versions of radiation. That’s why dentists and their assistants wear lead lined overalls to take X-rays.
Ionising and non-ionising
This is because X-Rays are ionising radiation.
In plain English ionising means radiation knocks molecules about. In living cells ionising radiation can trigger cancer.
Wireless signals are non-ionising radiation. Which means it doesn’t knock molecules about. There is no cancer effect.
Both types of radiation are part of the electromagnetic spectrum. Everyday wireless communications only uses non-ionising parts of the spectrum.
Non-ionising wireless radiation does generate heat. You can see this everyday with microwave ovens. They cook food. A microwave over could cook you if you climbed inside.
You need a lot of power to heat anything with electromagnetic energy. A lot more energy than you need to send and receive wireless signals. Microwave overs use hundreds of watts. If you stand at the bottom of a cellular tower the energy will be much less than a single watt.
The networks in place today operate at levels that are about one percent of the power needed to warm a human body.
Cooking with wireless
We learnt the hard way about electromagnetic heating. In the 1940s, high power equipment cooked people working on the UK’s radar defence. Since then we’ve learned how to shield radio waves. Your home microwave over includes a shield.
There are people who blame cellular electromagnetic fields for health problems.
One complaint is that electromagnetic radiation causes people to feel tired or confused. You also hear about headaches. Laboratory tests using placebos suggest these problems are not caused by radio waves.
Other causes can explain these symptoms. Hay fever has a similar effect and is often hard to track down. There are other possibilities.
As humans we often look for the most obvious answers for problems we don’t understand. If someone suggests a phone caused your ailment, it may sound plausible. Even if it is not. You might as well blame aliens.
5G is different, not that different
This brings us up to date at the dawn of the 5G era. Some anti–5G campaigners point out the technology is different to earlier cellular technologies. That’s true. 5G uses a wider range of frequencies. When and if cellular companies build denser tower networks, they will bath us more often in this wider range of frequencies.
Even so, the frequencies are still non-ionising radiation.
And although there will be more antennae, we will still be subject to low total levels of radiation. If if you are in range of a dozens of towers, there will not be enoough power for a measurable heating effect. There is no 5G health risk from heating.
Another comforting thought is that 5G uses higher frequency radiation. One of the characteristics of higher frequencies is that they penetrate less distance. They will only get a millimetre or two into your body.
In other words, 5G radiation is not going to kill you. It won’t even make you sick.
The risk is zero. Compare that with the risk of picking up your 5G phone while driving a car. That’s something you do need to worry about.
Can you trust them?
You might accept all this and still worry that governments and the industry are lying about 5G risks.
First, while we’ve never had to deal with the 5G spread of frequencies in the past, the science doesn’t change. It’s still non-ionising.
Likewise, if a 5G service provider bent the truth, rivals in competing technologies like fibre broadband wouldn’t hold back. This isn’t happening.
5G health rumours
The hardest aspect of this for some readers is that it feels like all radiation is dangerous. It may also feel like we are being lied to. Even with plenty of convincing evidence some people still think 5G feels wrong. Some of this is manipulation. There are people playing with your mind on matters like this.
You might ask yourself why people spread these rumours (paywall). It’s a huge problem and not only for 5G. Similar misinformation stops people from vaccinating children. In part, spreading these stories makes some people feel powerful and important.
There’s another angle, dark forces want to break any trust you might have in authorities. They want to turn you away from fact-based reasoning. This paves the way for their power plays. This aspect is well beyond the scope of this story.
At this point go back to what you can see with your own eyes. There are no busy hospital phone radiation departments. You don’t know anyone phone radiation has harmed or killed. Nor do your doctors or anyone else.
In short, you can stop worrying about 5G radiation. There are plenty of other things you should worry about more than 5G health risks.
