South Africa is in the midst of the fourth industrial revolution as it becomes more and more connected. RESHAAD SHA, Chief Executive Officer, SqwidNet, believes the heart of a smart city is the Internet of Things.
Along with the rest of the world, South Africa is in the midst of the fourth industrial revolution, in which the smart use of information and technology is reshaping societies. One of the most apparent ways in which this is happening can be seen is in the growth of the Internet of Things (IoT), where smart, connected devices are being deployed in cities and industries globally, to gather data and glean contextual insights which are used to achieve higher levels of efficiency, productivity and utilization of scarce and natural resources.
The reach of IoT is staggering. In the near future, for example, the growing population of nations will be fed by crops that are smartly planted at the right time and in precisely the right place to produce maximum yield. Leveraging IoT, farmers will be informed via connected sensors, of the precise dosage of water, fertilizer and nutrients that the piece of cultivated land will require to produce an optimal yield in terms of volume and quality.
As the need to respond to the increasing demand for food as well as and the effects of climate change on food security becomes a dominant concern, smart agriculture is just one of the ways in which IoT will, no doubt, prove its value.
Full steam ahead
More immediately, large metros in South Africa often face challenges with meeting citizen’s demand for electricity, dealing with water shortages and wastage, and managing other resources. Each of these challenges are only expected to grow in the years ahead due to increasing urbanisation, and in Africa this has become a significant driver behind conversations focusing on Smart Cities.
The good news is that exciting progress is already being made in South Africa, as we are seeing IoT projects underway and the development of smart cities being placed top of the agenda. Both, it should be noted, work hand in hand. In fact, IoT is essential to the success of a Smart City, as it enables the bridging of the physical world with the digital one.
Doing so enables a metro to gather real-time data from millions of objects, such as water meters, electricity meters, waste bins, traffic lights, and street lights. This forms the basis upon which contextual data can be collected, analysed, and used to manage the city in a smarter, predictive, and proactive way. A few practical examples of this include better traffic management by informing travellers of congestion; dealing with crime by leveraging sensors that detect gunshots in high crime zone areas; and smart waste management, in which metros are automatically informed by sensor-equipped bins when refuse needs to be collected.
The prime objective
Beyond the general benefits of living in a Smart City, with the greater quality of life brought about by a metro that is more efficiently managed, the burgeoning IoT industry presents some real opportunities for entrepreneurs in South Africa, particularly those businesses which enable big data to be efficiently gathered, processed, and analysed.
Job creation need not be limited to businesses in the big data space. Having smart cities in place will ensure that South Africa is ripe to attract global investment from the business sector. The most compelling advantage of smart cities is that they may very well offer an opportunity to boost South Africa’s economy, which would benefit all its citizens.
Rising to the challenge
However, before we can reap these benefits, there are some real challenges that must be addressed. The sheer volume of connected ‘things’ means the technologies make these objects smart must be available at a low device, connectivity, and implementation cost, so that substantial demands on cities’ budgets are avoided.
It is here in particular that SqwidNet, the result of a partnership between DFA and Sigfox, has an important role to play. Sigfox technology enables low-cost IoT connectivity for, among other things, water and electricity meters and city building and facilities management, which enables the deployment of smart city solutions at scale. The network now covers all the 8 metros in South Africa, and the rollout plan is currently focussed on covering all the national roads as well as moving to other cities and towns. Network coverage will exceed 85% of the South African population by the end of the year.
Other considerations that will need to be taken into account include the power requirements for smart objects, as it is impractical for the bulk of these objects to be connected to a fixed power source. Rather, sensors will have to consume very low power, allowing them to run on a small battery for several years. The Sigfox network and device ecosystem is designed so that devices only become active when they need to send or receive a message to or from the network. As a result of this, devices can last up to 15 years or more on a battery, depending on the use case.
Finally, the network that these objects and sensors connect to also has to be cost efficient, and it is imperative that the data transmitted by smart, connected things can be delivered securely to mitigate any risks to the city and its citizens. Sigfox has security embedded at all layers of the solution. Data is encrypted from the chipset and device layer, the data in motion layer and the data storage and data at rest layers as well. In addition to this, long range base stations, cloud based operating and management systems, and a broad range of device and chipset manufacturers and partners collectively contribute to low cost connectivity and end to end solutions and propositions to market.
International device roaming on the global Sigfox network is also addressed through roaming and clearing agreements between international Sigfox networks operators, with no additional costs to the end-user. This is a compelling proposition for asset tracking, supply chain, transport and logistics focussed IoT applications and services. Cities are also enabled to share this data across platforms, since the data protocols are non-proprietary, thus supporting the innovation and development of value-added applications and services for analytical and contextual driven city management.
If South Africa wants to keep its position as the gateway to Africa, our cities, the services it provides and the lifestyle it creates for citizens must be nothing less than the global standard that is being set by leading cities around the world. Considering the predicted growth of the continent, it is easy to see why developing smart cities in South Africa now is not only a necessity but also a smart investment in the country’s future.

Tech promotes connections across groups in emerging markets
Digital technology users say they more regularly interact with people from diverse backgrounds
Smartphone users – especially those who use social media – say they are more regularly exposed to people who have different backgrounds. They are also more connected with friends they don’t see in person, a Pew Research Center survey of adults in 11 emerging economies finds.
South Africa, included in the study, has among the most consistent levels of connection across age groups and education levels and in terms of cross-cultural connections. This suggests both that smartphones have had a greater democratisation impact in South Africa, but also that the country is more geared to diversity than most others. Of 11 countries surveyed, it has the second-lowest spread between those using smartphones and those not using them in terms of exposure to other religious groups.
Across every country surveyed, those who use smartphones are more likely than those who use less sophisticated phones or no phones at all to regularly interact with people from different religious groups. In most countries, people with smartphones also tend to be more likely to interact regularly with people from different political parties, income levels and racial or ethnic backgrounds.
The Center’s new report is the third in a series exploring digital connectivity among populations in emerging economies based on nationally representative surveys of adults in Colombia, India, Jordan, Kenya, Lebanon, Mexico, the Philippines, Tunisia, South Africa, Venezuela and Vietnam. Earlier reports examined attitudes toward misinformation and mobile technology’s social impact.
The survey finds that smartphone and social media use are intertwined: A median of 91% of smartphone users in these countries also use social media or messaging apps, while a median of 81% of social media users say they own or share a smartphone. And, as with smartphone users, social media and messaging app users stand apart from non-users in how often they interact with people who are different from them. For example, 52% of Mexican social media users say they regularly interact with people of a different income level, compared with 28% of non-users.
These results do not show with certainty that smartphones or social media are the cause of people feeling like they have more diverse networks. For example, those who have resources to buy and maintain a smartphone are likely to differ in many key ways from those who don’t, and it could be that some combination of those differences drives this phenomenon. Still, statistical modelling indicates that smartphone and social media use are independent predictors of greater social network diversity when other factors such as age, education and sex are held constant.
Other key findings in the report include:
- Mobile phones and social media are broadening people’s social networks. More than half in most countries say they see in person only about half or fewer of the people they call or text. Mobile phones are also allowing many to stay in touch with people who live far away: A median of 93% of mobile phone users across the 11 countries surveyed say their phones have mostly helped them keep in touch with those who are far-flung. When it comes to social media, large shares report relationships with “friends” online who are distinct from those they see in person. A median of 46% of Facebook users across the 11 countries report seeing few or none of their Facebook friends in person regularly, compared with a median of 31% of Facebook users who often see most or all of their Facebook friends in person.
- Social activities and information seeking on subjects like health and education top the list of mobile activities. The survey asked mobile phone users about 10 different activities they might do on their mobile phones – activities that are social, information-seeking or commercial in nature. Among the most commonly reported activities are casual, social activities. For example, a median of 82% of mobile phone users in the 11 countries surveyed say they used their phone over the past year to send text messages and a median of 69% of users say they took pictures or videos. Many mobile phone users are also using their phones to find new information. For example, a median of 61% of mobile phone users say they used their phones over the past year to look up information about health and medicine for themselves or their families. This is more than the proportion that reports using their phones to get news and information about politics (median of 47%) or to look up information about government services (37%). Additionally, around half or more of mobile phone users in nearly all countries report having used their phones over the past 12 months to learn something important for work or school.
- Digital divides emerge in the new mobile-social environment. People with smartphones and social media – as well as younger people, those with higher levels of education, and men – are in some ways reaping more benefits than others, potentially contributing to digital divides.
- People with smartphones are much more likely to engage in activities on their phones than people with less sophisticated devices – even if the activity itself is quite simple. For example, people with smartphones are more likely than those with feature or basic phones to send text messages in each of the 11 countries surveyed, even though the activity is technically feasible from all mobile phones. Those who have smartphones are also much more likely to look up information for their households, including about health and government services.
- There are also major differences in mobile usage by age and education level in how their devices are – or are not – broadening their horizons. Younger people are more likely to use their phones for nearly all activities asked about, whether those activities are social, information-seeking or commercial. Phone users with higher levels of education are also more likely to do most activities on their phones and to interact with those who are different from them regularly than those with lower levels of education.
- Gender, too, plays a role in what people do with their devices and how they are exposed to different people and information. Men are more likely than women to say they encounter people who are different from them, whether in terms of race, politics, religion or income. And men tend to be more likely to look up information about government services and to obtain political news and information.
These findings are drawn from a Pew Research Center survey conducted among 28,122 adults in 11 countries from Sept. 7 to Dec. 7, 2018. In addition to the survey, the Center conducted focus groups with participants in Kenya, Mexico, the Philippines and Tunisia in March 2018, and their comments are included throughout the report.
Nokia to be first with Android 10
Nokia is likely to be the first smartphone brand to roll out Android 10, after its manufacturer, HMD Global, announced that the Android 10 software upgrade would start in the fourth quarter of 2019.
Previously named Android Q, it was given the number after Google announced it was ditching sweet and dessert names due to confusion in different languages. Android 10 is due for release at the end of the year.
Juho Sarvikas, chief product officer of HMD Global said: “With a proven track record in delivering software updates fast, Nokia smartphones were the first whole portfolio to benefit from a 2-letter upgrade from Android Nougat to Android Oreo and then Android Pie. We were the fastest manufacturer to upgrade from Android Oreo to Android Pie across the range.
“With today’s roll out plan we look set to do it even faster for Android Pie to Android 10 upgrades. We are the only manufacturer 100% committed to having the latest Android across the entire portfolio.”
HMD Global has given a guarantee that Nokia smartphone owners benefit from two years of OS upgrades and 3 years of security updates.
