Somewhere in the Kruger National Park, Cole du Plessis steps out of his vehicle, and slowly waves a contraption that looks like a TV antenna. He watches a small digital display on a handheld device. Suddenly, it pings. He moves around. It pings twice.
“We’ve got signal,” he says with quiet satisfaction.
But he’s not talking about a cellphone signal. He’s just used a receiver that picks up VHF signals – low-power, short-range radio waves. The transmitter is fixed to a tracking collar that has been attached to an African wild dog – South Africa’s most endangered large carnivore. Du Plessis works for the Endangered Wildlife Trust (EWT), with the unique title of national wild dog meta population coordinator.
Cole’s focus on this single species is testament both to its endangered status – there are fewer than 500 surviving in South Africa – and the special nature of the animal. It’s one of the most socialised of all wild animals, with a highly structured social order, a collective style of hunting and an orderly approach to feeding on a kill, with the young always feeding first.
It is also one of the underdogs of the wild, with what the EWT calls “a mistaken reputation for attacking livestock”, which results in them being persecuted by humans as much as by lions. That’s aside from its susceptibility to poachers’ snares and even road accidents.
A combination of human and natural threats have resulted in the wild dog going extinct in 23 countries of Africa, and there are fewer than 5000 on the entire continent. That makes it even rarer than the rhino, which has become the poster animal for endangered wildlife.
Help is at hand, however, and technology is playing a major role in attempts to bring the species back from the brink of total extinction.
The EWT’s Kruger Rare Carnivore Program is a major project to investigate threats to wild dogs and factors affecting their numbers, as well as to track their movement in the Greater Kruger ecosystem.
Du Plessis previously worked with Wildlife ACT in kwaZulu-Natal, using telemetry to track and locate wild animals in smaller reserves. In smaller reserves, intensive monitoring was possible, as well as necessary, due to the proximity of local communities living around the reserves. The challenge in the Kruger Park is very different, largely due its size.
“In smaller reserves, VHF gives you the luxury of getting live tracking data every day,” says Du Plessis, who has a Masters degree in protected area management. “In the Kruger and in the Gorongoza in Mozambique, the rural nature of the area and the lack of road access means that, to find wild dogs, you have to use satellite collars with GPS devices fitted. So you have luxury of sitting on computers at home or the office and tracking them. The problem is, the more GPS data you want to download, the shorter the collar battery’s duration.”
He points out that animal tracking technology does not have the luxury of GPS tracking on cellphones, which have their batteries charged by human beings every day.
“There are three categories of collar: VHS is very old tech but very reliable, and uses very high frequency radio telemetry. GSM collars works off the cellphone network, have SIM cards built in, and relay information through cellular signals, based on proximity to a tower or handheld device.
“The third collar is the best type, using GPS, and there are different types. We traditionally used Sirtrack, a New Zealand company which developed satellite tracking collars for wildlife. But they cost around R55-60 000, so we couldn’t use too many. In KZN and Kruger we use all these categories of tracker.”
Fortunately, tracking collars are now being manufactured locally by African Wildlife Tracking, at half the cost of the imported versions.
David Marneweck, manager of the EWT’s Carnivore Conservation Programme, points out that the objectives for putting on the collar determine what technology is used.
“The more often we ask the collar to relay data, the shorter the battery life. If we want data once a day, it lasts a year and a half. If you’re doing a coarse study on habitat use, once a day is fine, but if you want to vaccinate a population, once every six hours makes more sense, and battery life is affected accordingly.”
When Du Plessis or other members of the world dog project pick up a signal, they are able to home in on the general location of a wild dog pack. Usually, due to the cost and complexity of collaring a dog, the focus is on the alpha male in each pack. This means that the entire pack can be tracked, even if only one dog is collared.
The collars have to be checked regularly, and the batteries replaced, and this can only be done by darting the animal to sedate it. Sometimes, it can take several days to track down a single wild dog. In the process, however, the team regularly comes across animals in distress.
During an expedition with the wild dog tracking team coordinated by Vodacom, we receive an urgent call: members of the team have come across an elephant caught in a poacher’s snare. It’s a crude wire trap, but it has cut deep into the elephant’s leg. The Kruger Park’s state vets are called, and they are quickly on the scene to sedate the animal, remove the snare and treat its injuries.
A few hours later, we finally find one of the elusive wild dogs. It is sedated, collar and battery checked, and after a few minutes the beautiful animal staggers to its feet and hobbles away.
Among the observers is John Mitchell, coach of the Vodacom Bulls rugby team. He is there with several of his players to see the tracking project in action. It is not a mere public relations exercise, though. Mitchell uses the wild dog as a metaphor for the strategies he has used to transform the team in the past year.
“They are not only underdogs, but they work as a team, win as a pack, and support each other even in most dangerous circumstances,” he explains. “Even if one is injured, it is never abandoned.”
Mitchell and his team are participating in the Vodacom Red Wild Dogs tour, part of a campaign that gives Vodacom Red clients a chance to win a once in a lifetime experience, based on their personal interests. The small group on this tour all combine a passion for rugby with a strong interest in wildlife.
Mitchell and the group watch with admiration as the tracking team and the vets, too, work in close cooperation. The vets and the wild dog tracking team have a symbiotic relationship, and it is clear that a deep mutual respect exists between them.
“Just implementing technology doesn’t mean you’re going to be successful,” says Marneweck. “You still have to use your expertise to achieve your goal, and to get wild dogs immobilised ethically and effectively within a reasonable period of time.”
Given the rapid advances in cellular, radio and satellite technology in just the last five years, one would expect tracking to become far easier and cheaper. Marneweck insits they have tried it all, and the advances that aid cellular connectivity still do not offer the range or battery efficiency that makes it practical for wildlife tracking across a vast area like the Kruger.
“Everything is based on battery life, and we’ve tried everything from kinetic technology to solar technology, like small solar panels. It’s a great idea, and we use it for vulture backpacks extremely successfully; it can last seven years. With dogs, however, they roll in the mud and get dirty. The panels fill with dirt very quickly and become useless.”
The benefits of tracking are massive.
“Without collars, wild dog conservation would not have been possible,” says Du Plessis. “Today is a case in point. It was so hard to find. Imagine if they didn’t have collars, it would have been impossible. As ugly as some people think collars are, wild dogs have been saved from snares by anti-snare plates fitted to the side of the collar, which absorbs the force of snare.”
The current project is a collaboration between SANparks, the state veterinary authority and the EWT. It started in July 2016, after an outbreak of canine distemper virus wiped pout a pack of wild dogs in the Kruger. The project is both a health survey and a targeted vaccination of wild dogs, to understand the threat and protect the animals from disease.
Next week it will have been running for two years, with 100 dogs successfully vaccinated. That makes it the largest vaccination ever of wild dogs. It also means every pack of wild dogs in the Kruger National Park is collared for the first time in the park’s history.
Samsung in lock-step with its rivals?
Tonight Samsung will kick off the next round in the smartphone wars with the S10 range, writes ARTHUR GOLDSTUCK.
When Samsung unveils the new S10 smartphone at an event in San Francisco today, it will mark the beginning of the 2019 round of World War S. That stands for smartphone wars, although Samsung would like it to be all about the S.
Ever since the launch of the Samsung Galaxy S4 in 2013, Samsung has held both technology and thought leadership in the handset world. Back then, Apple’s iPhone 5 was the last device from the American manufacturer that could lay claim to being the best smartphone in the world. With the 2013 launch of the iPhone 5s, Apple entered an era of incremental improvement, playing catch-up, and succumbing to market trends driven by its competitors.
Six years later, Samsung is fighting off the same threat. Its Chinese rival, Huawei, suddenly wrested away leadership in the past year, with the P20 Pro and Mate 20 Pro regarded as at last equal to the Samsung Galaxy S9 Plus and Galaxy Note 9 – if not superior. Certainly, from a cost perspective, Huawei took the lead with its more competitive prices, and therefore more value for money.
Huawei also succeeded where Apple failed: introducing more economical versions of its flagship phones. The iPhone 5c, SE and XR have all been disappointments in the sales department, mainly because the price difference was not massive enough to attract lower-income users. In contrast, the Lite editions of the Huawei P9, P10 and P20 have been huge successes, especially in South Africa.
Today, for the first time in half a decade, Samsung goes into battle on a field laid out by its competitors. It is expected to launch the Galaxy S10 Plus, S10 and S10 e, with the latter being the Samsung answer to the strategy of the iPhone XR and Huawei P20 Lite.
Does this mean Samsung is now in lock-step with its rivals, focused on matching their strategies rather than running ahead of them?
It may seem that way, but Samsung has a few tricks up its electronic sleeve. For example, it is possible it will use the S10 launch to announce its coming range of foldable phones, expected to be called the Galaxy X, Galaxy F, Galaxy Fold or Galaxy Flex. It previewed the technology at a developer conference in San Francisco last November, and this will be the ideal moment to reclaim technology leadership by going into production with foldables – even if the S10 range itself does not shoot out the lights.
However, the S10 handsets will look very different to their predecessors. First, before switching on the phone, they will be notable by the introduction of what is being called the punch-hole display, which breaks away from the current trend of having a notch at the top of the phone to house front-facing cameras and speakers. Instead, the punch-hole is a single round cut-out that will contain the front camera. It is the key element of Samsung’s “Infinity O” display – the O represents the punchhole – which will be the first truly edge-to-edge display, on the sides and top.
The S10 range will use the new Samsung user interface, One UI, also unveiled at the developer conference. It replaces the previous “skin”, unimaginatively called the Samsung Experience, to introduce a strong new interface brand.
One UI went live on the Note 8 last month, giving us a foretaste, and giving Samsung a chance to iron out the bugs in the field. It is a less cluttered interface, addressing one of the biggest complaints about most manufacturer skins. Only Nokia and Google Pixel handsets offer pure Android in the local market, but One UI is Samsung’s best compromise yet.
It introduces a new interaction area, in the bottom half, reachable with the thumb, with a viewing area at the top, allowing the user to work one-handed on the bottom area while still having apps or related content visible above. One UI also improves gesture navigation – the phone picks up hand movements without being touched – and notification management.
The S10 range will be the first phones to feature the latest Qualcomm Snapdragon 855 chip, at least for the South African and American markets. That makes it 5G compatible, for when this next generation of mobile broadband becomes available in these markets.
They will also be the first phones to feature Wi-Fi 6, the next generation of the Wi-Fi mobile wireless standard. It will perform better in congested areas, and data transfer will be up to 40% faster than the previous generation.
The phones will be the first to use ultrasound for fingerprint detection. If Samsung gets it right, this will make it the fastest in-screen fingerprint sensor on the market, and allows for a little leeway if one pushes the finger down slightly outside the fingerprint reader surface. It does mean, however, that screen protectors will have to be redesigned to avoid blocking the detection.
Not enough firsts? There are a few more.
Most notably, it will be the first phone range to feature 1 Terabyte (TB) storage – that’s a thousand Gigabytes (GB) – at least for the top-of-the-range devices. Samsung last month announced that it would be the first manufacturer to make 1TB built-in onboard flash storage. Today, it will deploy this massive advantage as it once again weaponises its technology in the fight for smartphone domination.

IoT set to improve authentication
By Sherry Zameer, Senior Vice President, Internet of Things Solutions for CISMEA region at Gemalto
As it rapidly approaches maturity, the Internet of Things (IoT) is set to continue a transformational trajectory, introducing new efficiencies in multiple fields by allowing measurement and analysis on a scale that has never been possible before. From agriculture to logistics, from retail to hospitality, from traffic to health, from the home to the office, the applications for monitoring ”things” are limited only by the imagination.
And South African (and African) businesses are showing abundant imagination in their practical deployments of IoT solutions in multiple settings, creating a better tomorrow through almost universal measurement and the introduction of new levels of convenience – including how to access locations, devices and services securely.
Any company, whether South African or international, should bear in mind that understanding consumer expectations can be the key to unlocking the full potential of IoT devices and related smart services.
According to Gemalto’s latest Connected Living study, improving the way consumers authenticate themselves to services is one of the most anticipated benefits of IoT, highlighting a desire for a more seamless and secure IoT experience.
Consumers are interested in advanced ways of authenticating themselves through automatic (based on behavioral patterns) or biometric techniques, lessening the need to have to intervene manually, all in the name of a much more streamlined authentication process. Smartphone manufacturers like Apple and Samsung have already placed fingerprint and facial recognition high on the agenda. There is also a widespread positive sentiment towards IoT’s potential for improving the quality of home life through connected, smart appliances.
Personalised services is something else that wins consumers over. In fact, a fluid, personalised and unified experience with continuity of services, together with security and privacy, is critical for the successful implementation of any technology.
And those types of services are today quite possible. With everything being connected – from small gadgets to digital solutions for large enterprises – IoT is no longer just a buzzword. That much is clear in a piece from Vodacom IoT managing executive Deon Liebenberg. Writing for IOL Online, Liebenberg provides insight into the sheer range of applications for IoT: the 20 use cases he cites range from the obvious, like transport and logistics, to the connected home and wearables; he even suggests tagging pets with IoT transmitters, for those who always need to know the whereabouts of the family cat.
Low-cost tags fitted to cats, dogs, lamp posts, shipping containers or other items are just one part of the puzzle, however. There are other two pieces; arguably the most complex part is the availability of communication networks in areas where there aren’t any WiFi networks, or indeed, anything else.
And that’s where the bigger takeaway from Liebenberg’s piece and other IoT trends articles becomes apparent. The communication networks are there, as are those tags: dedicated IoT networks (like LoraWAN, SigFox and narrowband IoT) are all available in South Africa.
So, too, is the third and final essential component. Software which is able to process the data generated by the tag and transmitted over the IoT network and into the internet. In this regard, there’s no shortage of solutions available from cloud providers like AWS and Azure; electronics giant Siemens, too, is in on the action, having recently launched a new cloud-based IoT operating system to develop applications and services for process industries, including oil and gas and water management.
This combination means it is quite possible right now to enable just about any use case. Business owners, who will know best how IoT can add value in their organisation, can now see their ideas becoming reality. Most crucial of all, IoT solutions delivering new levels of efficiency and convenience are not only possible, they are able to be offered with the simple and effective security that will drive consumer acceptance.
