The field trial demonstrated a 5G Fixed-Wireless Access (FWA) use case with Huawei’s 5G 28GHz mmWave Customer Premises Equipment (CPE) in a real-world environment in Hatfield Pretoria, South Africa. Speeds of 520Mbps downlink and 77Mbps uplink were attained throughout respectively.
“These 5G trials provide us with an opportunity to future proof our network and prepare it for the evolution of these new generation networks. We have gleaned invaluable insights about the modifications that we need to do on our core, radio and transmission network from these pilots. It is important to note that the transition to 5G is not just a flick of a switch, but it’s a roadmap that requires technical modifications and network architecture changes to ensure that we meet the standards that this technology requires. We are pleased that we are laying the groundwork that will lead to the full realisation of the boundless opportunities that are inherent in the digital world.” says Babak Fouladi, Group Chief Technology & Information Systems Officer, at MTN Group.
Giovanni Chiarelli, Chief Technology and Information Officer for MTN SA said: “Next generation services such as virtual and augmented reality, ultra-high definition video streaming, and cloud gaming require massive capacity and higher user data rates. The use of millimeter-wave spectrum bands is one of the key 5G enabling technologies to deliver the required capacity and massive data rates required for 5G’s Enhanced Mobile Broadband use cases. MTN and Huawei’s joint field trial of the first 5G mmWave Fixed-Wireless Access solution in Africa will also pave the way for a fixed-wireless access solution that is capable of replacing conventional fixed access technologies, such as fibre.”
“Huawei is continuing to invest heavily in innovative 5G technologies”, said Edward Deng, President of Wireless Network Product Line of Huawei. “5G mmWave technology can achieve unprecedented fiber-like speed for mobile broadband access. This trial has shown the capabilities of 5G technology to deliver exceptional user experience for Enhanced Mobile Broadband applications. With customer-centric innovation in mind, Huawei will continue to partner with MTN to deliver best-in-class advanced wireless solutions.”
“We are excited about the potential the technology will bring as well as the potential advancements we will see in the fields of medicine, entertainment and education. MTN has been investing heavily to further improve our network, with the recent “Best in Test” and MyBroadband best network recognition affirming this. With our focus on providing the South Africans with the best customer experience, speedy allocation of spectrum can help bring more of these technologies to our customers,” says Giovanni.
The myths of microwaves
We all know microwaves make cooking a breeze and it helps save those minutes, we rarely have enough of these days. However, some people do have those lingering doubts about whether microwaving food destroys nutrients or that it emits harmful radiation. However, the truth is a lot more comforting and positive.
“The microwave makes life so much easier,” says Tracy Gordon, Head of Product – Home Appliances at Samsung South Africa. “It’s human-centred technology at its most helpful. The Samsung Hotblast for example, has revolutionary functions, which are tailor-made to create fast, tasty and healthy meals in minutes.”
A recent article by Harvard Health Publishingclaims stated that “microwave ovens cook food using waves of energy that are remarkably selective, primarily affecting water and other molecules that are electrically asymmetrical. Microwaves cause these molecules to vibrate and quickly build up thermal (heat) energy.” The article debunks two common myths about microwaving food.
Myth 1: Microwaving kills nutrients
Whether in a microwave or a regular oven, some nutrients, including vitamin C, do break down when exposed to heat. However, the fact is, cooking with a microwave might be better when it comes to preserving nutrients because it takes a shorter time to cook. Additionally, as far as vegetables go, cooking them in water robs them of some of their nutritional value because the nutrients seep out into the cooking water,” states the report by Harvard Health Publishing. According to the World Health Organisation (WHO), food cooked in a microwave oven is as safe and has the same nutrient value, as food cooked in a conventional oven.
Myth 2: Microwaving food can give you cancer
The American Cancer Society (ACS) says that microwaves do not make food radioactive. Microwaves heat food but they do not change the chemical or molecular structure of it. In fact, there is absolutely no evidence that microwaves pose a health risk to people when used appropriately, the organisation added.
With those myths well busted, it’s comforting to know one can make full use of the convenient kitchen appliance. And when the time comes to use a microwave to heat up a tasty meal in no time, one can trust the Samsung Hotblast to do the job. The HotBlast has multiple air holes blowing out powerful hot air, which reduces cooking time. Samsung claims the Slim Fry technology ensures that food is perfectly crisp on the outside and delicious and juicy on the inside. Additionally, this versatile microwave has a wider grill, making it easier to brown food fast and evenly. The turntable is wider, measuring 345mm, making it possible to prepare bigger portions of food. And with its Eco Mode power, it significantly reduces energy consumption with its low standby power. Its intelligent features and stylish design makes it very useful and as we now know – a safe, healthy way to enjoy a meal.
New BMW 3-series ushers in autonomous future
The new BMW 3-series is not meant to be an autonomous car, but it is so close, ARTHUR GOLDSTUCK discovers.
It was not meant to be a test-drive of an autonomous vehicle. But the Driving Assist button on the steering wheel of the new BMW 330i was just too tempting. And there I found myself, on Sir Lowry’s Pass near Cape Town, “driving” with my arms folded while the vehicle negotiated curves on its own.
Every 10 seconds or so, yellow or red lights flashed to alert me to put my hands back on the wheel. The yellow lights meant the car wanted me to put my hands on the wheel, just to show that I was in control. The red lights meant that I had to take over control from the artificial intelligence built into the vehicle.
With co-driver Ernest Page, we negotiated a major highway, the bends of Sir Lowry’s pass, and the passes of Hell’s Heights (Hel se Hoogte) above the Cape Winelands.
As the above video of the experience reveals, it can be nerve-racking for someone who hasn’t experienced autonomous driving, or hasn’t been dreaming of testing it for many years. For this driver, it was exhilarating. Not because the car performed so magnificently, but because it tells us just how close true autonomous driving really is.
There was one nervous moment when the autonomous – or rather, Driving Assist – mode disengaged on Hell’s Heights, but fear not. A powerful sense of responsibility prevailed, and my hands hovered over the steering wheel as it took the curve. Assist disengaged, and the car began to veer towards the other side of the road. I quickly took over, and also sobered up from the giddiness of thinking I was already in the future.
In reality, Driving Assist is part of level 2 of driving autonomy, as defined by the Society of Automotive Engineers. A presentation on the evening of the test drive, by Edward Makwana, manager of group product communications at BMW Group in South Africa, summed up the five stages as the driver having Feet Off, Hands Off, Eyes Off, Mind off, and finally, only being a Passenger.
However, the extent to which the hands-off mode of Driving Assist mimics self-driving, and easily shows the way to eyes-off and mind-off, is astonishing.
