The Internet of Things is one of the latest buzzwords in the IT industry. It promises to transform how we live and work, but for some its still very difficult to understand. VINCE RESENTE, Enterprise Technology Specialist at Intel attempts to demystify the IoT.
Ah, the Internet of Things. It’s the topic on everyone’s lips – the buzzword of the year. It promises to transform the way we live and work, to free us from mundane tasks, and create entirely new jobs in entirely new industries.
Ask anyone in technology to explain the IoT and they’ll probably use words like sensors, big data and networks, and tell you how, together, these produce real-time insights and business intelligence.
No wonder the man on the street isn’t as excited about the IoT as those in the industry are. For something that is expected to have massive impacts on the lives of every person on the planet, the IoT should be easier to understand.
Demystifying the IoT
The high-level definition of the IoT is a collection of sensors that feed information into a database to make sense of things.
That’s not the most user-friendly explanation.
Let’s rather think of the IoT as a human body – we’ll call him John.
John’s central nervous system is the database and his senses (sight, smell, touch, etc) are, well, the sensors.
When information enters John’s nervous system (database) through his senses (sensors), he interprets it immediately and responds accordingly – he pulls his hand away from a hot stove; he sidesteps an uncovered manhole; he turns down the volume on the TV if it’s too loud.
The heat from the plate, the sight of the open manhole, and the TV volume is all data, which John analyses in real-time, allowing him to make instant decisions. He uses this information to protect himself by predicting outcomes before they occur – like falling into the manhole and seriously injuring himself.
Making businesses smarter
This is, in essence, how the IoT works.
Businesses in any vertical can monitor and analyse just about any variable. This analysis allows them to make better business decisions in response to changing conditions, in real time. They can also predict what is likely to happen in the future and put measures in place to protect themselves from financial loss or to better position themselves to leverage future opportunities.
These decisions – or business intelligence – keep them ahead of their competitors, help them save time and money through unnecessary downtime, and ensure their systems always perform optimally.
Let’s consider some of the variables a courier company – we’ll call it ABCDeliveries – might monitor. By monitoring traffic patterns through apps like Waze, GPS data and traffic light sensors, ABCDeliveries can calculate the fastest route between destinations, saving it time on the road and allowing it to complete more deliveries in a day, which equates to more revenue. By monitoring the weather, ABCDeliveries will know when to move packages undercover to prevent damage from rain or hail, saving it money in insurance claims.
A key aspect of the IoT is that big data is time-stamped. Traffic information from yesterday is useless to ABCDeliveries today. It needs to know what is happening right now so that it can react appropriately.
Humans as sensors
Thousands of South Africans use the IoT every day, possibly without realising it. Anyone who travels with the Waze navigation app is essentially part of a bigger IoT ecosystem.
Users opt in to share their movements and to report road hazards, faulty traffic lights and police sightings, meaning they are, essentially, the sensors that submit data – of John’s senses. This information is disseminated to other Waze users travelling on the same route.
If 20 people give a hazard report a thumbs up, it’s likely still there. If 10 give it a thumbs down, it’s probably not and Waze will remove it from the hazard list. That’s a big data decision made in real time in response to data coming in from thousands of sensors.
The effects? People are able to avoid congested roads and discover new routes that get them to work faster. Imagine how much simpler our lives will be when we can look inside our fridges from our phones while doing grocery shopping, or when we can turn on the heaters from work to arrive to a warm home in winter?
There is not a single vertical that will not benefit from the IoT, but we first need to understand how it works so that we can get more people excited about it – and more people developing for it – so we can all realise these benefits sooner.
Android Go puts reliable smartphones in budget pockets
Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.
Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.
Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps.
Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.
Vodafone Smart Kicka 4
At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.
The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018.
Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games.
Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.
Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer.
The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past.
Huawei Y3 (2018)
The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are.
Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.
Comparing the 3
All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker.
Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.
SA gets digital archive
As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.
The southafrica.co.za site carries content about the country’s collective heritage in South Africa’s eleven official languages.
Designed as a nation building, educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.
The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.
At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.
Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.
“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.
Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island. The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
