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.
Smash hits the
Super Smash Bros. delivers what the fans wanted in the latest “Ultimate” instalment, writes BRYAN TURNER.
Super Smash Bros. Ultimate, the latest addition to the popular Nintendo Smash series, has landed on the Nintendo Switch with a bang, selling 5-million copies in the first week of its release. The game has been long-anticipated since the console’s release, as many fans consider
It features 74 playable fighters, 108 stages, almost 1300 Spirit characters to collect while playing, and a single-player Adventure mode that took about three days (or 28 hours) of gameplay to complete. The game offers far more gameplay than its predecessors, making it the Smash game that gives its players the best bang for their buck.
For those new to the game, the goal is to fight opponents and build up their damage score (draining their health) to knock them off the stage eventually. This makes the game seem chaotic, as many players jump around the platforms as if they were on quicksand, in order to avoid being hit by the other players.
It also services two kinds of players: the competitive and the casual.
Competitive players can be matched on the online service by skill ranking to enjoy playing with similarly high-skilled opponents. This is especially important in e-sports training for the game, and for players wanting to master combos against other human players. The casual gamer is also catered for, with eight-player chaos and button-mashing to see who comes out luckiest. This segment is also important for those wanting to learn how to play.
Training mode is also a place to go for those learning to play. It offers “CPU” players that are graded by intensity to train as a single player to learn a character’s moves, combos and general fighting style. More challenging CPU players can also be used by competitive players to train when there isn’t a Wi-Fi connection available.
Direct Play features in this game, allowing two players with two Switch consoles to play against each other over a direct connection – no Wi-Fi needed. This is especially useful to those who want to have a social gaming element on the go, similar to that of the cable connector of the Gameboy.

Win Funko Fortnite in Vinyl
Gadget and Gammatek have nine Funko Fortnite figurines to give away.
A Funko Pop figurine based on a character set is indicative of reaching the heights of pop culture. It is no surprise, then, that the world’s biggest online game, Fortnite, has its own line of Funko Pop figurines. The Funkos are modeled on the characters in game, including Drift, Ragnarok, Dark Vanguard, Volar, Tracera Ops, and Sparkle Specialist.
Now, local Funko distributor Gammatek has released the Fortnite figurines in South Africa. To celebrate, Gadget and Gammatek are giving away a set of three Funko Fortnite figurines to each of three readers (9 figurines in total). To enter,
