According to SHERRY ZAMEER of Gemalto, if we don’t build robust security into our 5G networks, we will miss the big opportunity this technology offers us.
The current expectation is that the first commercial 5G networks will be rolled out in 2020, just two years away. The early adopters will naturally be those countries whose 4G networks are already in place, but there is no doubt that African players are already busy laying the foundations for their future 5G plays.
“It is clear that 5G has huge potential to unlock all sorts of new solutions, especially as an enabler for the Internet of Things, but all the behind-the-scenes preparatory work will be wasted if security is not prioritised,” says Sherry Zameer, Senior VP IOT in CISMEA region at Gemalto. “5G has the potential to transform the use case for mobility dramatically, but it will require innovative and robust security solutions to be in place.”
Big operators in Africa will be gearing up to demonstrate the performance jump 5G offers: download speeds of 20 gigabits per second meaning that there is very little delay between transmission and reception of a signal. This “immediate” response to commands is essential for many futuristic applications; driverless cars, for example, need split-second responses, as do critical health care and industrial applications.
Sherry Zameer says that Gemalto is deeply engaged in helping develop security standards, primarily interacting with industry organisations like the GSMA (which represents the interests of mobile operators) and NGMN (Next Generation Mobile Networks).
As one might expect, many of the characteristics that make 5G so attractive create some of these critical security vulnerabilities:
5G will be critical for the Internet of Things.
5G’s speed and latency alone will make it a key platform for the expanding Internet of Things. Also, it will enable virtualised network infrastructures designed for specific uses. The result will be a mix of open-source and proprietary software and hardware on the network. This will mean that traditional mobile networks built on hardware/ software combinations provided by trusted vendors will become much more heterogeneous—and will provide a greater attack surface than current cellular networks.
5G will enable a much more flexible use of “edge” resources to take load off the core network. The caching of local content will change the way that data and cellular communications are stored—and secured.
The nature of the threat will change.
As more and more devices come onto the 5G network, mobile networks’ traditional focus on preventing eavesdropping will be supplanted by a need to protect against data manipulation and similar types of attack. Such attacks could be used to instruct a machine to perform an unwanted action, like opening a factory gate to robbers, taking control of an autonomous vehicle or disabling warning systems.
A complicating factor will be that many of the devices connected to the network will not be able to encrypt communications, the traditional first line of network defence. Another issue will be the sheer volume of machine-to-machine communication—maintaining the confidentiality and integrity of this data will be no sinecure.
This complex threat landscape will mean that both network operators and the manufacturers of consumer electronics will have the opportunity to provide security as a service. These offerings would be graded to the level of threat to the particular data stream, and its importance.
“Africa is pre-eminently mobile when it comes to communications technologies and the Internet. 5G thus has a potentially important role to play as the continent seeks to establish itself as a player in the global economy,” Sherry concludes. “We must not fall into the trap of just seeing it as a technical and financing challenge: if we don’t build robust security into our 5G networks, we will miss the big opportunity this technology offers us.”
Samsung clears the table with new monitor
For those who like minimalism and tidy desks, Samsung’s new Space Monitor may just do the trick, writes BRYAN TURNER.
The latest trends of narrow-bezels and minimalist designs have transcended smartphones, spilling into other designs, like laptops and monitors.
The new Space Monitor line by Samsung follows in this new design “tradition”. The company has moved the monitor off the desk – by clipping it onto the edge of the desk.
It can be put into three configurations: completely upright, where it sits a bit high but completely off the desk; half-way to the desk, where it is a bit lower to put some papers or files underneath the display; and flat on the desk, where it is at its lowest.
The monitor sits on a weighted hinge at the edge of the desk, providing sturdy adjustment to its various height configurations. It also swivels on a hinge at the point where the arm connects to the display. This provides precise viewing angle adjustment, which is great for showing something on screen to someone who is standing.
Apart from form factor, there are some neat goodies packed into the box. It comes with a two-pin power adapter, with no adapter box on the midpoint between the plug and the monitor, and a single cable that carries HDMI-Y and power to prevent tangling.
However, it’s slightly disappointing that there isn’t a Mini Display Port and power cable “in one cable” option for Mac and newer graphics card users, who will have to run two cables down the back of the screen. Even worse, the display doesn’t have a USB Type-C display input; a missed opportunity to connect a Samsung device to the panel.
A redeeming point is the stunning, Samsung-quality panel, which features a 4K UHD resolution. The colours are sharp and the viewing angles are good. However, this display is missing something: Pantone or Adobe RGB colour certification, as well as IPS technology.
The display’s response rate comes in at 4ms, slightly below average for displays in this price range.
These negatives aside, this display has a very specific purpose. It’s for those who want to create desk space in a few seconds, while not having to rearrange the room.
Final verdict: This display is not for gamers nor for graphic designers. It is for those who need big displays but frequently
Can mobile fix education?
By Ernst Wittmann, global account director for MEA and country manager for Southern Africa, at TCL Communications
Mobile technology has transformed the way we live and work, and it can be expected to rapidly change the ways in which children learn as smartphones and tablets become more widely accepted at primary and high schools. By putting a powerful computer in every learner’s schoolbag or pocket, smartphones could play an important role in improving educational outcomes in a country where so many schools are under-resourced.
Here are some ways that mobile technology will reshape education in the years to come:
Organisation and productivity
For many adults, the real benefit of a smartphone comes from simple applications like messaging, calendaring and email. The same goes for schoolchildren, many of whom will get the most value from basic apps like sending a WhatApp message to friends to check on the homework for the day, keeping track of their extramural calendar, or photographing the teacher’s notes from the blackboard or whiteboard. One study of young people’s mobile phone use in Ghana, Malawi and South Africa confirmed that many of them got the most value from using their phones to complete mundane tasks.
One of the major benefits smartphones can bring to the classroom is boosting learners’ engagement with educational materials through rich media and interactivity. For example, apps like Mathletics use gamification to get children excited about doing mathematics—they turn learning into a game, with rewards for practicing and hitting milestones. Or teachers can set up a simple poll using an app like Poll Everywhere to ask the children in a class what they think about a character’s motivation in their English set-work book.
Mobile technology opens the doors to more
For example, teachers can provide recommended educational materials for children who are racing in ahead of their peers in some of their subjects. Or they can suggest relevant games for children who learn better through practical application of ideas than by listening to a teacher and taking notes.
In future, we can expect to see teachers, perhaps aided by algorithms and artificial intelligence, make use of analytics to track how students engage with educational content on their mobile devices and use these insights to create more powerful learning experiences.
South Africa has a shortage of teachers in key subjects such as mathematics and science, which disproportionately affects learners in poor and rural areas. According to a statement in 2017 from the Department of Basic Education, it has more than 5,000 underqualified or unqualified teachers working around the country. Though technology cannot substitute for a qualified teacher, it can supplement human teaching in remote or poor areas where teachers are not available or not qualified to teach certain subjects. Video learning and videoconferencing sessions offer the next best thing where a math or physical science teacher is not physically present in the classroom.
Knowledge is power and the Internet is the world’s biggest repository of knowledge. Schoolchildren can access information and expertise about every subject under the sun from their smartphones – whether they are reading the news on a portal, watching documentaries on YouTube, downloading electronic books, using apps to improve their language skills, or simply Googling facts and figures for a school project.
Take a mobile-first approach
Technology has a powerful role to play in the South African school of the future, but there are some key success factors schools must bear in mind as they bring mobile devices into the classroom:
- Use appropriate technology—in South Africa, that means taking a mobile-first approach and using the smartphones many children already know and use.
- Thinking about challenges such as security – put in place the cyber and physical security needed to keep phones and data safe and secure.
- Ensuring teachers and children alike are trained to make the most of the tech – teachers need to take an active role in curating content and guiding schoolchildren’s use of their devices. To get that right, they will need training and access to reliable tech support.
