The Phantom Prospects of 5G

Source: Light Reading

Telcos are once again touting a new generation of mobile protocols as their saviour. And once again, we should raise an arched eyebrow. 

A great piece by Mike Dano from Light Reading dissects the reasons behind — and the challenges facing — telcos’ push for 5G. And why you shouldn’t be expecting 5G to rock your world any time soon.

The reasons are relatively simple. The above chart from Wall Street analysts MoffettNathanson show how, for US telcos (and the story is similar elsewhere) there’s a lot more data traffic (the black line) , but a lot less money being made per user (the blue line).

So telcos need something new. Hence 5G. But how are they going to make money out of it? The old thinking about 4G was that the improved speeds and bandwidth was going to enable telcos to make more money out of each user. But that hasn’t happened (see chart again.) So why do they think 5G will be any different?

5G is going to be very expensive to deploy. This is not just a question of attaching a new box or upgrading an existing one to an existing basestation or tower. Mike quotes MoffettNathanson in a recent research note on Verizon. “Deploying 5G networks with enough density to meet expectations for blazing fast 5G speeds will cost real money. If not from charging more for using more, then where will the money come from?”

Atop that are the problems of heat, which I’ve written about before.

So the most likely outcome of 5G, at least in the first few years, is that it’s aimed at business. Think the Internet of Things (IoT): connected (and self-driving) cars, smart cities, healthcare, industrial automation. Or outdoor surveillance cameras, according to a Gartner report cited by Mike, which says this is likely to be the largest market for 5G in the short term.

But even then, there are questions about this. This won’t be cheap for enterprises. And 3G and 4G hardly shone when it came to connecting devices. Attaching a modem to a device and then having that ping back is expensive — installing and replacing a battery, if necessary, having and managing a SIM card for each device, etc.

Ericsson, one of the cheerleaders for mobile IoT, acknowledges in a June report that despite its grand claims for a mobile IoT future, most mobile IoT devices are actually using 2G and 3G:

Today, the majority of cellular IoT devices are connected via 2G and 3G technologies (GPRS, EDGE and HSPA). The number of legacy connections is expected to increase slightly until 2022, and then remain stable throughout the rest of the forecast period.

Hard to imagine that’s a huge source of revenue.

And then there’s narrowband IoT, which I’ve written about before. Yes, 5G offers the kind of speed and low latency that would be attractive for a lot of use cases, but when you just need to send a few bytes narrowband is much more appealing. And needn’t involve the telcos at all.

Most likely outcome? Telcos are going to have to demonstrate, somehow, to customers that the new use cases they’re hoping will save them will actually work. And that means working closely with them or investing in them, or vice versa. Build it and they will come might be the mantra, but that is going to require a lot of faith that they will indeed come, and in a timeframe that makes sense. New verticals don’t pop up overnight.

5G’s Achilles Heel: Heat

5G promises a lot. a mobile internet of things, new immersive VR and AR experiences, lower latency, washboard stomachs. But something the industry isn’t addressing is that the devices themselves heat up. A lot. This from Digits to Dollars‘ Jonathan Goldberg: 

5G phones get hot. Really hot. Probably not hot enough to ignite your battery (probably), but enough to generate a definite burning sensation in your pants pockets. At Mobile World Congress in February, we spoke with an engineer from Sony who was demo’ing a phone (behind glass) that was clocking 1 Gbps speeds. Wow, fast. We asked the engineer why it was not going faster and he said “It overheats.” A good solid answer, from a nuts-and-bolts-and-antenna person. We will wager any amount that at next year’s show, no one on the floor will be as open about this problem.

The industry, Goldberg writes, is tackling this issue by er, ignoring it. And indeed the standard response appears to be that “we’ve seen heat problems with every new generation and what we have with 5G is nothing significant, 3G was way worse,” as one commenter said he’d been told at a 5G conference. But that may be underestimating the problem — Goldberg says the “heat budget” is 67% higher than current phones. (Heat budget is the total amount of thermal energy transferred to the chip when the device is in operation.) And he points out that both no-one seems yet to be offering a solutions and “solving the issue in 3G broke a couple vendors.” 

Some background: what we call 5G is actually two stages of technology. What most carriers are currently rolling out is phase 1, or what is called, confusingly, sub 6, an evolution of 4G that bring (quoting Goldberg again in a different post): “modest improvements in data rates as well as some important, but hard to observe, changes in the software the operators use to run their networks.” The big step will be the second phase, mmWave, “will bring much more tangible changes, notably including data rates at or above 1 Gbps.”It’s these mmWave radios that are (indirectly) causing the problem. 

As I understand it, these mmWave operate at very high frequencies — close to microwave — which require high clock speeds in the chips. The heat this creates is concentrated in a small subset of the electronic components within the phone, and there’s no easy way to move that energy around. Goldberg again: 

Of course there are some solutions, but none of them are complete and they all have serious drawbacks. It turns out that the way we cool electronics has not advanced in 40 years. There are really two methods used currently to cool Things down- Fans and Dissipation.

Fans are what you think they are. Anyone who has ever opened up their desktop PC or overclocked their laptop knows what these look like. But fans have two problems: they are big and they have moving parts. Both of those require design decisions that go counter to every mobile design trend in the past 15 years.

Dissipation is just the idea of moving the heat around to hasten air cooling. In a PC, this is typified by those funny looking prong-things that sit on top of CPUs. Those things are too tall to fit inside a 10mm thick phone. So for mobiles, OEMs are looking at using ‘straws’, or copper pipes that span the length of the phone. These take up a lot of space and inserting a large conductive element (copper!) inside a phone wreaks havoc on mobile radios, (i.e. hurting data rates).

We all know the problems of overheating phones, but what is surprising is how little this issue seems to be addressed. Goldberg says that this is a problem on a whole new level to previous generations, and one that is only now being addressed: “The problems with 5G mmWave are larger and will not go away as quickly. Handset makers are just waking up to the existence of this problem.”

The only place to find discussion of this issue appears to be in academia, which itself notes the lack of discussion. In a paper published last year three researchers at the Huazhong University of Science and Technology wrote (PDF):

the heat dissipation of smartphones restricts the maximum receiving rate of smartphones. Although the maximum receiving rate of smartphones is restricted by the computation capability and heat dissipation, detailed studies of basic models used for evaluating the maximum receiving rate of smartphones are surprisingly rare in the available literature.

The researchers ran their own tests and reached some sobering conclusions: 

– anything above 4 Gbps and the temperature of the smartphone reaches above 45 C “within a few seconds.” (5G has promised peak data rates up to 20 Gbps and Qualcomm’s first 5G modem “is designed to achieve up to 5Gbps downlink peak data rate.” So the smartphone has to “decrease the computation capability of the chip to reduce the heat generation, e.g., decrease the working frequency of the chip, to prevent low-temperature burns on the user’s skin. Thus, smartphones cannot sustain the original receiving rate and may even have to shut off wireless communications.” This is obviously not an optimal outcome. This is already happening with the first mmWave 5G rollouts (what AT&T calls 5G+) — which, remember, is not the one that involves mmWave radios: The Wall Street Journal wrote in July that their Galaxy S10’s 5G switched off in the Icelandic summer. Others have reported similar problems.

The researchers recommend that to address this”using new materials or redesigning the components’ structure to improve the heat conduction rate from the chip to other low-temperature components in smartphones. Additionally, mobile edge computing, one of the 5G technologies, can be applied to improve the maximum receiving rate of smartphones by offloading the computation assignments in the chips.” It’s hard to imagine that would be a welcome advance, since as I understand it it would mean transferring a lot of the hard work from the phone to the base station — and who exactly would pay for that? 

The researchers are, in their academic way, somewhat scathing of how the field has failed to address the serious matter of device heat: “In 5G and future 6G cellular networks, most of research is focused on the core networks and BSs. However, many potential impacts triggered by the maximum receiving rate of smartphones have not yet been investigated. How to design reasonable mobile terminals for matching with 5G and future 6G wireless communication systems is still an open issue for industries and academic researchers.” 

That was a year ago. One can only hope the device manufacturers are addressing this. For now, it seems to make sense to take 5G promises with a pinch of salt and a bucket of ice.

Narrowband Goes Broad

Seems LoRa is really taking off. Citing data from research firm Analysys Mason, Chris Donkin writes that 85 new networks were announced as live, in a trial phase or in development in 2016 compared with 29 in 2015.

While early LPWA deployments were concentrated in the US and Western Europe, Analysys Mason found interest in the technology spread during 2016, with strong traction being seen in the APAC market.

During 2015, two thirds of initiatives took place in the US and Western Europe whereas in 2016 the figure was down to less than a third. Simultaneously APAC showed growth from 4 per cent in 2015 to 30 per cent in 2016.

The report identified developments in Japan, Singapore, South Korea, Australia and New Zealand as being especially significant in the regional shift identified last year.

While a lot of these led by SigFox or operators using the NB-IoT standard — a stripped down 3G, more interesting, I think is the LoRa version, which actually provided the single largest group — 29 deployments vs 27 Sigfox.

The LoRa Alliance says 17 nationwide deployments have been publicly announced, and there are live networks in more than 150 cities. So I’m guessing AM’s numbers are somewhat conservative. The Things Network, an open source implementation of LoRa, boasts dozens of communities — people who are working on networks, however small — and while most are in Europe and the US, Australia is strong — Sydney’s Meshed Network Pty has installed five gateways around the city.

The author of the AM piece, Aris Xylouris, says “we can expect more announcements to be made before Mobile World Congress (MWC) 2017. It is likely that the launch of the first real commercial deployment of an NB-IoT network will be among the announcements at MWC 2017.”

Here’s my take from August on narrowband.

Why we hate video calls

Good piece in the New Scientist about why we’ve always hated video calls:

When another New York Times reporter went to Pittsburgh in mid-1971, however, he found only 33 Picturephones in operation, with just 12 able to dial outside their own buildings. Aside from impracticalities such as cost, it seemed that, against all predictions, no one actually wanted video calling. Users were more interested in seeing graphics than face-to-face video conversation. At Bell Labs, Lucky recalls that the only person who called his Picturephone was his boss, Arno Penzias. “I found it very awkward because I had to stare at him,” he says.

More than that, I think the enduring non-appeal of video is that it doesn’t start to replace talking face to face. Face to face talking is not about seeing the other person, or looking them in the eyes — it’s about non-verbal communication — gestures, body language, touching, etc. It’s also about allowing other things to intervene — movement, distraction, interaction with objects.

Video calls are exhausting, because you are trying to replace all that with just maintaining eye contact, or at least giving the appearance of remaining engaged. It’s a new form of communication, and we’ve tried and rejected it. Whenever Cisco drag me over to their HQ for some elaborate video conference I always feel it’s a waste of time, and a major overengineering of a flawed medium.

Talking on the phone, meanwhile, suits us perfectly (although I’ve come to hate it almost as much as video calling.) As George Costanza once said, after going through a phone conversation with a blind date:

George: She had to be impressed by that conversation, had to! It was a great performance. I am unbelievable on the phone. On the date they should just have two phones on the table at the restaurant, done.

Phone calls have become useful because we are able to transfer a lot of the body language and non-verbal cues into speech (and silence). We’re still working on text chat, but we’re getting there. It works — it’s not exhausting. It’s communicating what we want to communicate, and filtering out what we don’t — and not reading, at least for the most part, anything into anything else.

Singapore’s M1 aims narrowband deployment at the sea

Singapore telco M1 is getting Nokia to install an NB-IoT network atop its 4G one, interestingly with an eye not just to land but to sea. 

NB-IoT stands for Narrowband Internet of Things, and is the GSM world’s answer to narrowband technologies such as LoRa and Sigifox that threaten to take away a chunk of their business when the Internet of things does eventually take off. Why use expensive modems and services when you’re just trying to connect devices which want to tell you whether they’re on or off, full or empty, fixed or broken?  

Techgoondu reports: “While that network caters to heavy users who stream videos or songs on the go, a separate network that M1 is setting up at the same time is aimed at the smart cars, sensors and even wearables.

They said pricing will likely vary with each solution or package, with some companies saving costs from deploying large amounts of connected sensors. However, others that require the bandwidth, say, to deliver surveillance videos over the air, would likely stick with existing 4G networks.

And while many NB-IoT devices are still on the drawing board – standards for the network were only finalised in June – M1 executives were upbeat about jumping on the bandwagon early.

Alex Tan, the telco’s chief innovation officer, said the technology would open up new business opportunities in the years ahead.”

A press release from M1 says it’s working with the ports authority — Singapore is one of the biggest ports in the world — to  “explore the deployment of a network of offshore sensors to augment the situational awareness of our port waters,” according to Andrew Tan, Chief Executive of the Maritime and Port Authority, MPA.

This follows Sigfox’s deployment in the city state last month. It also pips to the post rival Singtel who have been talking since February about running a trial of NB-IoT with Ericsson.  (Update: “Our preparation to trial NB-IoT is well underway. We are working with our vendors and industry partners to conduct lab trials in December, with a view to launch an NB-IoT network by mid-2017.”)

Remote control : LoRa offers a cheaper link to the Internet of Things

By Jeremy Wagstaff

LAUNCESTON, Australia, Reuters – The future of communications may be 5G, where mobile networks push bandwidth-heavy video to phones and pull data from self-driving cars, but some firms see an alternative: farm irrigation equipment, donation boxes and oysters, connected by a technology called LoRa.

LoRa (for Long Range) is among a clutch of narrow band technologies that connect devices cheaply over unlicensed spectrum and vast distances, needing very little power.

The catch: they can only send small parcels of data rather than the gigabytes most wired and mobile standards aspire to.

But, advocates say, that may be more than enough.

‘It turns out you don’t need that huge an infrastructure, and it can be driven by small devices that are very smart and not very expensive,’ says Mike Cruse, CEO of Definium Technologies, which is building LoRa-based devices for farmers, universities and mines.

The so-called Internet of Things (IoT) has long promised to hook up devices, from aircraft to hair dryers, enabling owners to monitor, control and collect data from them remotely. Spending on the IoT will hit $6 trillion between 2015 and 2020, according to PricewaterhouseCoopers.

But the reality has been slow catching up. Ericsson this year almost halved the number of connected devices – including smartphones – it sees by 2020 to 28 billion.

Part of what’s holding things back, critics say, is that solutions are too expensive and elaborate for what is needed. Most involve cellular connections, which are either impractical in rural areas or beyond a user’s budget.

Take Richard Gardner, who runs a 2,500 hectare (6,178 acre) farm in Tasmania and pays A$1,200 per sensor for a cellular-based soil moisture measuring system. He’s working with Definium to design one costing a tenth of that.

‘There’s a lot of technology out there that works now, it’s just very expensive. We’ve got something now that we think has better attributes and is cheaper,’ says Gardner, who has invested in Definium and says he already has other farmers keen to buy the company’s products.

 

Making all this possible is LoRa, a narrow band standard adopted by the likes of Cisco and IBM, where the thumbnail-sized radios that send and receive data sell for a dollar or less.

Dutch enthusiasts are building a global community of open-source LoRa gateways, called the Things Network. Nodes send and receive messages – about a tenth of the size of an SMS – every couple of minutes to once every few hours. Followers have rolled out their own experimental networks using the community’s software in cities from Colombia to Russia.

Founder Wienke Giezeman says a $300 gateway – the router connecting the LoRa nodes to the Internet – will be available next month. Half a dozen would be enough to cover an average-sized city. ‘This,’ he says, ‘is going to push the next phase of growth.’

And LoRa isn’t the only narrow band technology in town.

Weightless, a British-based alliance, is one. Another is a proprietary U.S. technology run by a company called Ingenu, as is Sigfox, a French firm, which has raised $150 million from companies including Samsung Electronics.

The biggest potential losers are the telecoms companies, the traditional gatekeepers to the coverage these networks now claim. Ericsson says only 1.5 billion of the 16 billion IoT devices it reckons will be connected in 2021 will rely on cellular networks.

Some telecoms firms are counting on NB-IOT, a narrow band standard adopted by the industry that would use their existing cellular networks. Others are hedging their bets by building LoRa and other narrow band networks.

SK Telecom, for example, has rolled out a network across South Korea which it said would cost users a tenth of what they would pay to attach devices to its 4G network.

RELATED COVERAGE

Likely winners from LoRa networks in IoT Lagging, however, is how best to use these networks.

Charles Anderson, an analyst at IDC, says governments and companies are still pondering what might work, and what end users might want.

In the meantime, smaller players are feeling their way. One visitor to a booth at a recent IoT show in Singapore suggested connecting donation collection boxes so she’d know when they need emptying.

Rishabh Chauhan of The Things Network says the community is still experimenting – from remotely monitoring mouse traps to whether moored rowboats have filled with water. ‘It seems people have a use case, but want to see it on a small level. They’re still prototyping,’ he said.

Much of the pioneering work is outside cities, where existing networks are poor.

Gardner, the farmer, for example, sees the potential for monitoring water flow and levels, the voltage in his electric fences, or his crop sprinklers. Knowing whether they’re working properly would save two trips a day and cut fuel bills, he says.

In a back-room lab, Definium’s Cruse shows some of the sensors he’s designing for clients, all of which could easily connect to a LoRa network.

They include one for measuring salt levels for shrimp farmers in Bangladesh; an LED street lamp for a mining company that could be controlled remotely; a squirrel trap which would alert a catch, and a biosensor attached to an oyster to gauge its health.

Tweetwars: the social challenge in Twitter ‘capital’, Indonesia

My effort to take a closer look at Twitter’s capital. 

Tweetwars: the social challenge in Twitter ‘capital’, Indonesia | Reuters:

BY JEREMY WAGSTAFF

TWITTER INDONESIA  1

Indonesia has long been the Twitter capital of the world, but rival apps and rancorous political debate are driving users away, illustrating the challenges the microblogging service faces even in markets once considered strongholds.

While Twitter doesn’t break down country figures, Global Web Index data shows Indonesia remains joint first with Mexico in active users among the 34 countries the UK-based metrics company monitors – and significantly ahead in terms of penetration, at 74 percent of all Internet users.

But that masks a deeper shift, analysts and users say, as changing tastes, culture and politics push Indonesians to rival services. The proportion of active Twitter users in Indonesia has dipped 10 percentage points in the past two years, to about one third of Internet users, the Global Web Index data show.

‘Unless Twitter makes changes or there’s some new exciting things on Twitter that can’t be found on other platforms then I don’t think people are coming back to Twitter,’ said Enda Nasution, a blogger and entrepreneur who has nearly 200,000 followers on his Twitter account.

A Twitter spokesman declined to comment on the data, saying he had not seen it, but said younger people in major markets like Indonesia and India were eager users. He said the company was expanding in Indonesia and working with airlines, banks and celebrities to add services and content.

He noted Indonesia was one of the top markets for Twitter’s recent acquisition Periscope, which allows users to stream live video.

Twitter on Wednesday reported its first quarter since going public with no growth in users, and announced changes to its global service.

Among younger users – active Twitter users in the 16-24 year age range – Indonesia lags Spain, Mexico and the UK. JakPat, an Indonesian survey company, found last month that teenagers were less likely to use Twitter regularly than those aged 26 and above, and were switching to other apps such as Facebook and its photosharing sibling Instagram.

But there’s also a push factor: Indonesians are leery of Twitter’s core appeal; its default public feed, where everything a user posts is visible to everyone on the network. What was once an attraction in Indonesia’s sociable culture became a liability in 2014’s fractious presidential election.

FISTICUFFS

As politicians saw the power of Twitter to mobilize support, the network was flooded by digital armies of volunteers and automated accounts, or bots, spawning what Shafiq Pontoh, chief strategic officer at Jakarta-based social media consultancy Provetic, described as a ‘tsunami’ of ‘black campaigns, hoaxes, prejudice, racism, spam, harassment, anonymous accounts and political action to frame topics, issues (and) spin doctoring.’

‘Twitter,’ he said, ‘became an uncomfortable place to be.’

This antagonism hit rock bottom when two Twitter users took a dispute over government car-making policies offline and slugged it out near a sports stadium. Cellphone footage of their fist-fight was broadcast on TV.

‘After that it felt like that if you don’t want to get into trouble, people would retreat and find a more comfortable space online,’ said Nasution, the entrepreneur.

Those online spaces include Facebook’s WhatsApp and Messenger apps, South Korean Kakao’s Path, Japan’s Naver Corp’s LINE and BlackBerry’s Messenger.

Nasution said students he has spoken to use WhatsApp to communicate with their lecturer, and LINE to chat with each other. Or Facebook and Path, says student Jeremiah Mandey, who joined Twitter in 2010. ‘I used Twitter to interact with friends, but now I use it to get news,’ he said.

MISSING A CULTURAL BEAT

Government departments, companies and even President Joko Widodo have embraced Twitter as a public announcement service. The Jakarta police traffic feed, alerting commuters to jams, accidents, potholes and protests, has over 5 million followers.

This provides a service, but is too passive for younger people, says Aulia Masna, an editor. ‘People are on social media to have fun and be entertained,’ he says. ‘Twitter in Indonesia is better known as the place for news, debate and politics. So it attracts the more serious, older crowd.’

The company spokesman said Twitter opened a Jakarta office last year and added staff, in part to expand its user base beyond the capital. The recruits included a government relations expert. It was also working with local bank BNI to allow customers to transact via Twitter.

‘We see great potential in Indonesia, it’s one of the top markets,’ he said, adding Widodo was due to visit Twitter’s headquarters in San Francisco next week.

Simon Kemp, regional managing partner of social media marketing agency We Are Social, said Twitter should focus more on understanding how people in places like Indonesia use their service before tweaking things.

‘People are still looking at these things as a technology base,’ he said, ‘while it’s the cultural driver that determines what you use and when you use it.’

The End of the Google+ Era?

Alex Chitu of the Google Operating System sees in Google’s decision to buy into the Twitter firehose the End of the Google+ Era:

Google announced that it will start to display tweets in Google Search for mobile. “When you’re searching on the Google app or any browser on your phone or tablet, you can find real-time content from Twitter right in the search results,” informs Google.

He sees this as the final nail in the coffin of Google+ as a real time social media service: 

It’s the end of the Google+ era. Even if Google+ will continue to exist in one way or another, Google will stop promoting it aggressively and will probably use it as a backend service. Bloomberg reports that Google “is set to reveal an online picture sharing and storage service that will no longer be part of the Google+ social network” and “will let users post images to Facebook and Twitter”.

He could well be right. I know that a lot of folk see positives in Google+ as an active network for certain interests, but Google has never been interested in anything less than mega scale, and won’t settle for that, I’m sure.

The Facebook Experiment: Some Collated Views

A few pieces in the Facebook Experiment. I’m still mulling my view. 

Paul Bernal: The Facebook Experiment: the ‘why’ questions…:

 Perhaps Facebook will look a little bad for a little while – but the potential financial benefit from the new stream of advertising revenue, the ability to squeeze more money from a market that looks increasingly saturated and competitive, outweighs that cost.

Based on the past record, they’re quite likely to be right. People will probably complain about this for a while, and then when the hoo-haa dies down, Facebook will still have over a billion users, and new ways to make money from them. Mark Zuckerberg doesn’t mind looking like the bad guy (again) for a little while. Why should he? The money will continue to flow – and whether it impacts upon the privacy and autonomy of the people on Facebook doesn’t matter to Facebook one way or another. It has ever been thus….

(Via Paul Bernal’s Blog)

A contrarian view from Rohan Samarajiva: Confused objections to Facebook emotional contagion research:

I am puzzled by the predominantly negative reaction to the manipulation of Facebook content, in the recent published research article in the mainstream media (MSM), though perhaps less in blogs and such.

It seems to me that MSM’s reaction is hypocritical. They manipulate their content all the time to evoke different emotional responses from their readers/viewers/listeners. The difference is that conducting research on resultant emotional changes on MSM is not as easy as on Facebook. For example, magazines have used different cover images, darkening or lightening faces and so. Their only indicator of success is whether version A sold more than version B. Not very nuanced.

(Via LIRNEasia)

And Ed Felten: Privacy Implications of Social Media Manipulation:

To be clear, I am not concluding that Facebook necessarily learned much of anything about the manipulability of any particular user. Based on what we know I would bet against the experiment having revealed that kind of information about any individual. My point is simpler: experiments that manipulate user experience impact users’ privacy, and that privacy impact needs to be taken into account in evaluating the ethics of such experiments and in determining when users should be informed.

(Via Freedom to Tinker)

And finally from Robin Wilton: Ethical Data Handling and Facebook’s “Emotional Contagion” Study:

Once, in a workshop, while discussing mechanisms for privacy preference expression, I said I would be happier for data subjects to have some means of expressing a preference than none. An older, wiser participant made the following wry remark: “That only brings a benefit if someone is prepared to give weight to their preference. If not… well, ten million times zero is still zero”. And that’s the weight Facebook appears to have given to the legitimate interests of its data subjects.

BBC: Old Scams Made New

This is a column for a BBC World Service piece. It’s not Reuters content. 

Of all the scams you’d have thought the old ‘I’m a general’s widow and am sitting on a whole pile of cash I want to share with you” one would have gone away by now. But it hasn’t. The scammers are now recruiting church organists. 

Take, for example, LinkedIn, the business networking service. Think Facebook but for suits. People use to flaunt their resume only in the hope of winning contracts, promotions, job offers and to share trade gossip with others. Companies use it to recruit, promote themselves etc. And so do scammers. 

They make a fake profile, add a fake photo, and then start inviting potential victims to connect to them. Once connected, they approach marks with the usual ‘I’ve got lots of money tied up in a bank and i want to share it with you if you’d only send a bit my way to help me grease some bankers’ palms.’ They can also now mine your address book and connect to your contacts and do the same to them. 

I was recently approached, for example, by a lady called Alisha, who claimed to work at a dental clinic (the giveaway there: she called it a detal clinic),by Qatari billionaire Sheikh Faisal Bin Qassim Al Thani (email address sheikfaisalbinalthani at gmail.com) and before her recent troubles by the now deposed prime minister of Thailand — Yingluck Shinawatra, not the other one — who could be reached at angeleena rosa 1967 at yahoo.com

Why do I know these folk are not for real? Well, one red flag is a limited number of connections: 67 in Alisha’s case, 127 in the Sheikh’s and 56 in Ms Yingluck’s. But each was able to reach me because despite the relatively measly number of people they’d persuade to accept their invitation to connect were contacts of mine.

I knew it was getting serious when I was approached by someone claiming to be a manager at Standard Chartered. Let’s call him Mr Christopher to save some blushes. Mr. Christopher claims to have 10 years’ experience in banking and finance management — and, most impressively, more than 500 connections. Among them a colleague, a CEO at a local energy group and the finance director of an Indonesian company. He even has a Facebook page. 

These scammers are putting in the hours. 

 But even then, these scams aren’t really that hard to spot.

Usually a glance at the profile is enough. A guy called Nigel Rozzell, for example, approached me, ostensibly from NatWest Bank. (It turns out there really is a Nigel Rozzell who works for Nat West Bank, but I’m pretty sure his email address isn’t Natwest Nigel at accountant.com, which is what this profile had.) 

And if I still wasn’t sure, I could search google for images that look like his mug shot — it’s actually easier than it sounds. And sure thing, the headshot of fake Nigel Rozzell belongs to an engineer who works on rail projects in Qatar.

And our bank manager friend Mr Christopher, with the 500+ connections and the Facebook page? After I recklessly accepted his LinkedIn invitation he offered me half of 9,649,400 pounds he said he was about to get his hands on. My confidence in him deflated when I discovered via Google that his mug shot belonged to that of the organist at a church near Bristol, who was none too pleased when I told him his visage being used as part of a scam. 

Now, LinkedIn to their credit have taken down all these profiles. And they defend their failure to stop these profiles ever appearing or gathering steam by saying that it’s basically up to users to be careful who they link to and to report anomalies. They also say they see no spike in these kinds of scams. 

But the truth is that scammers like networks and networks don’t police themselves. It took me anything between 10 seconds and two minutes to spot these scams, but I’m a nerd. That vetting process that could easily be automated. LinkedIn should, in my view, try doing that. I’ll miss rubbing shoulders with deposed prime ministers, billionaire sheiks and church organists, but I’ll suffer for the greater good of keeping scammers off my buddy list. 

[Update: Got another scam this morning, from a Douglas Mattes, who once again had 500+ connections and a quite well populated profile. And whom actually I thought might be legit as I hadn’t looked at the image which belongs to one Shaun Goeldner. I’m frankly unclear how these profiles work — are they legitimate accounts hacked or built from scratch?] 

[Update: Is this all part of some Iranian spying scam? ]
