Ericsson doubles mobile speed on same spectrum

Published

on

Even though 5G is only expected to become available in 2020, Ericsson has found a way to deliver drop-free, higher capacity mobile connections for both people and things – while making the most of available spectrum.

The next big generation of mobile networking, known as 5G, is not expected to be commercially available until 2020, but Ericsson already has indoor and outdoor 5G test networks in Sweden and the US. Ericsson’s latest 5G technology breakthrough provides a way to deliver drop-free, higher capacity mobile connections for both people and things – while making the most of available spectrum.

Mischa Dohler, Chair Professor of Wireless Communications and Head of the Centre for Telecommunications Research (CTR), King’s College London, says:  “High-speed, highly reliable mobile networks are foundational to the tactile internet and the internet of skills that it will enable. The results that are being achieved in Ericsson’s live 5G test networks — much faster data rates, more resilient connections and squeezing capacity out of spectrum – are all critical to unleashing the new use cases that will drive 5G.”

Ericsson’s latest 5G innovation sounds deceptively simple: The 5G mobile device connects to more than one 5G cell site at the same time. This is known as 5G multipoint connectivity.   It provides the resiliency to ensure that the 5G device maintains a high-quality connection with the 5G network as it moves between cells. It also enables the transmission of different sets of multiple data signals (Multiple Input Multiple Output, or MIMO, streams) to the mobile device over the same frequency band. This is called distributed MIMO, and it can increase downlink throughput by 100%. And, because it is all transmitted in the same frequency band, it makes very efficient use of available spectrum. The combined technical capability is called Multipoint Connectivity with Distributed MIMO.

Dr. Håkan Andersson, 5G Strategic Product Manager, Business Unit Radio, Ericsson, says:  “To be ready for commercial networks in 2020, 5G research and development has to come out of the labs and into live test networks. Multipoint Connectivity with Distributed MIMO, supported on Ericsson’s 5G air interface, is just the latest example of 5G innovation moving into live test network implementation.”

Multipoint Connectivity with Distributed MIMO involves very sophisticated signaling methods, which are not part of today’s LTE standards, to control the mobile device’s interaction with the network.  So, while LTE technology is evolving to become an integral part of tomorrow’s 5G networks, 5G will also include innovative new air interfaces (including signaling, modulation schemes and other software-driven innovations) between the device and the network.  Ericsson’s 5G air interface, dubbed “NX”, powers Multipoint Connectivity with Distributed MIMO.

5G will evolve the entire communication eco-system, from devices to mobile access, IP core and into the cloud. Ericsson’s latest 5G test network innovations focus on the interactions between mobile devices and the radio access network, indoors and outside.

Ericsson’s 5G test networks, including both 5G devices and 5G radio base stations, are running live at the company’s US and worldwide headquarters in Plano and Stockholm.  The company welcomes mobile operators, eco-system partners, members of academia, tech media and analysts to visit these sites to witness and interact with Ericsson 5G innovations.

IoT at tipping point

We have long been in the hype phase of IoT, but it is finally taking on a more concrete form illustrating its benefits to business and the public at large, says PAUL RUINAARD, Country Manager at Nutanix Sub-Saharan Africa.

People have become comfortable with talking to their smartphones and tasking these mini-computers to find the closest restaurants, schedule appointments, and even switch on their connected washing machines while they are stuck in traffic.

This is considerable progress from those expensive (and dated) robotic vacuum cleaners that drew some interest a few years ago. Yes, being able to automate cleaning the carpets held promise, but the reality failed to deliver on those expectations.

However, people’s growing comfort when it comes to talking to machines and letting them complete menial tasks is not what the long-anticipated Internet of Things (IoT) is about. It really entails taking connectedness a step further by getting machines to talk to one another in an increasingly digital world filled with smart cities, devices, and ways of doing things.

We have long been in the hype phase of IoT, but it is finally taking on a more concrete form illustrating its benefits to business and the public at large. The GSM Association predicts that Africa will account for nearly 60 percent of the anticipated 30 billion connected IoT devices by 2020.

Use cases across the continent hold much promise. In agriculture, for example, placing sensors in soil enable farmers to track acidity levels, temperature, and other variables to assist in improving crop yields. In some hotels, infrared sensors are being used to detect body heat so cleaning staff now when they can enter a room. In South Africa, connected cars (think telematics) are nothing new. Many local insurers use the data generated to reward good driver behaviour and penalise bad ones with higher premiums.

Data management

The proliferation of IoT also means huge opportunity for businesses. According to the IDC, the market opportunity for IoT in South Africa will grow to $1.7 billion by 2021. And with research from Statista showing that retail IoT spending in the country is expected to grow to $60 million by the end of this year (compared to the $41 million of 2016), there is significant potential for connected devices once organisations start to unlock the value of the data being generated.

But before we get a real sense of what our newly-connected world will look like and the full picture of the business opportunities IoT will create, we need to put the right resources in place to manage it. With IoT comes data, more than we can realistically imagine, and we are already creating more data than ever before.

Processing data is something usually left to ‘the IT person’. However, if business leaders want to join the IoT game, then it is something they must start thinking about. Sure, there are several ways to process data but they all link back to a data centre, that room or piece of equipment in the office, or the public data centre down the road. Most know it is there but little else, other than it has something to do with data and computers.

Data centres are the less interesting but very essential tools in all things technology. They run the show, and without them we would not be able to do something as simple as send an email, let alone create an intricate system of connected devices that constantly communicate with each other.

Traditionally, data centres have been large, expensive and clunky machines. But like everything in technology, they have been modernised over the years and have become smaller, more powerful, and more practical for the digital demands of today.

Computing on the edge

Imagine real-time face scanning being used at the Currie Cup final or the Chiefs and Pirates derby. Just imagine more than a thousand cameras in action, working in real time scanning tens of thousands of faces from different angles, creating data all along the way and integrating with other technology such as police radios and in-stadium services.

As South Africans, we know all too well that the bandwidth to process such a large amount of data through traditional networks is simply not good enough to work efficiently. And while it can be run through a large core or public data centre, the likelihood of one of those being close to the stadium is minimal. Delays, or ‘latency and lag time’, are not an option in this scenario; it must work in real time or not at all.

So, what can be done? The answer lies in edge computing. This is where computing is brought closer to the devices being used. The edge refers to devices that communicate with each other. Think of all those connected things the IoT has become known for: things like mobile devices, sensors, fitness trackers, laptops, and so on. Essentially anything that is ‘remote’ that links to the Web or other devices falls under this umbrella. For the most part, edge computing refers to smaller data centres (those in the edge) that can process the data required for things like large-scale facial recognition.

At some point in the future, there could be an edge data centre at Newlands or The Calabash that processes the data in real time. It would, of course, also be connected to other resources such as a public or private cloud environment, but the ‘heavy lifting’ is done where the action is taking place.

Unfortunately, there are not enough of these edge resources in place to match our grand IoT ambitions. Clearly, this must change if we are to continue much further down the IoT path.

Admittedly, edge computing is not the most exciting part of the IoT revolution, but it is perhaps the most necessary component of it if there is to be a revolution at all.

Don’t panic! Future of work is still human

Published

on

The digital age, and the new technologies it’s brought with it – blockchain, artificial intelligence (AI), robotics, augmented reality and virtual reality – is seen by many as a threat to our way of life as we know it. What if my job gets automated? How will I stay relevant? How do we adapt to the need for new skills to manage customer expectations and the flood of data that’s washing over us?

The bad news is that the nature of work has already changed irrevocably. Everything that can be automated, will be. We already live in an age of “robot restaurants”, where you order on a touch screen, and machines cook and serve your food. Did you notice the difference? AmazonGo is providing shopping without checkout lines. In the US alone, there are an estimated 3.4 million drivers that could be replaced by self-driving vehicles in 10 years, including truck drivers, taxi drivers and bus drivers.

We’re not immune from this phenomenon in Africa. In fact, the World Economic Forum (WEF) predicts that 41% of all work activities in South Africa are susceptible to automation, compared to 44% in Ethiopia, 46% in Nigeria and 52% in Kenya. This doesn’t mean millions of jobs on the continent will be automated overnight, but it’s a clear indicator of the future direction we’re taking.

The good news is that we don’t need to panic. What’s important for us in South Africa, and the continent, is to realise that there is plenty of work that only humans can do. This is particularly relevant to the African context, as the working-age population rises to 600 million in 2030 from 370 million in 2010. We have a groundswell of young people who need jobs – and the digital age has the ability to provide them, if we start working now.

Make no mistake, there’s no doubt that this so-called “Fourth Industrial Revolution” is going to disrupt many occupations. This is perfectly natural: every Industrial Revolution has made some jobs redundant. At the same time, these Revolutions have created vast new opportunities that have taken us forward exponentially.

Between 2012 and 2017, for example, it’s estimated that the demand for data analysts globally grew by 372%, and the demand for data visualisation skills by more than 2000%. As businesses, this means we have to not only create new jobs in areas like data science and analytics, but reskill our existing workforces to deal with the digital revolution and its new demands.

So, while bus drivers and data clerks are looking over their shoulders nervously right now, we’re seeing a vast range of new jobs being created in fields such as STEM (Science, Technology, Engineering and Mathematics), data analysis, computer science and engineering.

This is a challenge for Sub-Saharan Africa, where our levels of STEM education are still not where they should be. That doesn’t mean there are no opportunities to be had. In the region, for example, we have a real opportunity to create a new generation of home-grown African digital creators, designers and makers, not just “digital deliverers”. People who understand African nuances and stories, and who not only speak local languages, but are fluent in digital.

This ability to bridge the digital and physical worlds, as it were, will be the new gold for Africa. We need more business operations data analysts, who combine deep knowledge of their industry with the latest analytical tools to adapt business strategies. There will also be more demand for user interface experts, who can facilitate seamless human-machine interaction.

Of course, in the longer term, we in Africa are going to have to make some fundamental decisions about how we educate people if we’re going to be a part of this brave new world. Governments, big business and civil society will all have roles to play in creating more future-ready education systems, including expanded access to early-childhood education, more skilled teachers, investments in digital fluency and ICT literacy skills, and providing robust technical and vocational education and training (TVET). This will take significant intent not only from a policy point of view, but also the financial means to fund this.

None of this will happen overnight. So what can we, as individuals and businesspeople, do in the meantime? A good start would be to realise that the old models of learning and work are broken. Jenny Dearborn, SAP’s Global Head of Learning, talks about how the old approach to learning and work was generally a three-stage life that consisted largely of learn-work-retire.

Today, we live in what Ms Dearborn calls the multi-stage life, which includes numerous phases of learn-work-change-learn-work. And where before, the learning was often by rote, because information was finite, learning now is all about critical thinking, complex problem-solving, creativity and innovation and even the ability to un-learn what you have learned before.

Helping instill this culture of lifelong learning, including the provision of adult training and upskilling infrastructure, is something that all companies can do, starting now. The research is clear: even if jobs are stable or growing, they are going through major changes to their skills profile. WEF’s Future of Jobs analysis found that, in South Africa alone, 39% of core skills required across all occupations will be different by 2020 compared to what was needed to perform those roles in 2015.

This is a huge wake-up call to companies to invest meaningfully in on-the-job training to keep their people – and themselves – relevant in this new digital age. There’s no doubt that more learning will need to take place in the workplace, and greater private sector involvement is needed. As employers, we have to start working closely with should therefore offer schools, universities and even non-formal education to provide learning opportunities to our workers.

We can also drive a far stronger focus on the so-called “soft skills”, which is often used as a slightly dismissive term in the workplace. The core skills needed in today’s workplace are active listening, speaking, and critical thinking. A quick look at the WEF’s “21st Century Skills Required For The Future Of Work” chart bears this out: as much as we need literacy, numeracy and IT skills to make sense of the modern world of work, we also need innately human skills like communication and collaboration. The good news is that not only can these be taught – but they can be taught within the work environment.

It sounds almost counter-intuitive, but to be successful in the Digital Age, businesses are going to have to go back to what has always made them strong: their people. Everyone can buy AI, build data warehouses, and automate every process in sight. The companies that will stand out will be those that that focus on the things that can’t be duplicated by AI or machine learning – uniquely human skills.

I have no doubt that the future will not be humans OR robots: it will be humans AND robots, working side by side. For us, as businesspeople and children of the African continent, we’re on the brink of a major opportunity. We just have to grasp it.
