Upgrading a city’s physical infrastructure is one way of making it smart, but it is a short fix says WAYNE HULL, MD for Accenture Digital SA, who believes a smart city needs to tap into networks like the IoT and 5G.
An increasing number of major African metros are beginning to outgrow themselves. Ageing populations, increasing urban density, resource issues and mobility constraints – these are among the primary issues faced by urban areas.
Upgrading or adding to physical infrastructure is possible, but urban adjustment is notoriously slow, and cities’ budgets are increasingly tight. To cope with the demands they’ll face tomorrow, cities need to find ways of making the most of what they’ve got today.
By optimising the flow of everything from traffic to electricity and information around a city, urban life can become far easier, with the potential for cost savings through reduced waste.
Intelligent digital-physical interfaces have the potential to enable new opportunities for resource maximisation, efficiency gains and an enhanced quality of life for end users – in this case, the citizens of major metro areas.
The challenges faced by today’s metros are multifaceted. On one hand, metros are faced with increasing demands for accountability and transparency by citizens and activist groups. On the other, cities face the task of better serving citizens against a backdrop of sub-optimal and fragmented legacy systems, siloed data stores and budgetary, resource and skills constraints.
It’s a confluence that has given rise to the ‘smart city’ concept. In a smart city, digital-physical interfaces, sensors, smart software and Internet of Things-centred technologies work together to enhance and streamline how the city runs. By tapping into and analysing multiple networks of real-time information – covering everything from traffic flow to parking and electricity usage – smart city technologies are focused on one thing: optimising available resources.
IoT, 5G and a new network paradigm
Unlike current mobile networks which employ ‘large-cell’ technology – with macro cell towers, each of which services a large area – smart city networks require an inverse type of architecture: a dense lattice of small cells (data processing devices and sensors) spread throughout the city, fitted anywhere from utility poles to buildings’ basements, and which run 5G technology.
Within 5G networks, the emphasis shifts from media consumption to mobility, and from increased bandwidth to reduced latency. Further changes come in the form of the integration of network function virtualisation (NFV) and software defined network (SDN) capabilities within the network itself, allowing for the move from always-on coverage to instant service instantiation as and when needed.
Future 5G networks will host a variety of service types. Those falling under massive machine-type communication (mMTC), for example, include applications such as telemetry, meters, public lighting systems and security devices.
Further examples of mMTC solutions include the management of vehicle traffic and electrical grids, with the possibility for substantial savings through reductions in energy use, traffic congestion and fuel. Smart public lighting concepts, for example, automatically dim public lighting when no pedestrians or vehicles are near, conserving power, while still keeping a neighbourhood safe.
Still further mMTC applications include sensors designed to detect leaks in water mains, with such ultra-low power devices allowing sensors to run for many years without needing battery replacement.
A second service type, critical machine type communication, includes applications such as vehicle-to-vehicle communication, autonomous vehicles and public transport. Smart city technologies have the ability to improve public transport systems, for example, by reducing wait times, optimising utilisation and – with information from traffic flow sensors – allowing for dynamic routing. More broadly, smart cities have the potential to reduce traffic congestion overall, through smart traffic management systems.
Smart cities and the city ‘OS’
Co-innovation and co-creation are likely to play key roles in the development of smart city technologies, the combination of which can be thought of as a city operating system, or city OS. To enable the necessary changes, however, thinking must move from evolutionary – improving on services and applications enabled by current mobile networks – to revolutionary, employing new approaches directed toward new entirely new use cases.
From citizens’ perspectives, living in a smart city means the potential for anything from access to a more efficient public transport system to enhanced safety and security. For municipalities, benefits centre around improved citizen outcomes, the ability to engage in predictive maintenance, better use of data and more efficient resource use, meaning cost savings for many cash-strapped metros.
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.
