MWC 2015: Huawei to unveil 5G tech

Published

on

Huawei has announced that it will reveal a range of 5G-oriented air interface technologies at the 2015 Mobile World Congress (MWC) next month.

As 5G becomes increasingly prominent in today’s telecom industry, it will undoubtedly be the hottest topic to be featured at this year’s Mobile World Congress in Barcelona. Innovations surrounding 5G are driven by the increasing appetite for mobile Internet and the Internet of Things (IoT): All of which are expected to dominate by 2020 and beyond, and to deliver the ultimate user experience based on traffic growth of 1,000%. In order to fully develop 5G technology and revolutionary air interface techniques, networking techniques, and network architectures are prerequisites. Of all these emerging techniques, next-generation air interface is most essential and fundamentally significant.

As a result of investing heavily into next generation technology research, Huawei’s 5G R&D team has achieved remarkable breakthroughs in 5G air interface, virtualized radio access, as well as new RF technologies. Among the new air interface techniques proposed by Huawei, the self-adaptive and software-defined air interface designs, namely the non-orthogonal access technology based on Sparse Code Multiple Access (SCMA), and Filtered-Orthogonal Frequency Division Multiplexing (F-OFDM) are the most remarkable. Huawei has successfully tested the validity of its conceptual prototype. The results proved that the new air interface design can effectively improve spectral efficiency, increase connectivity, and reduce latency, thus facilitating the deployment of customized scenarios applied to the Internet of Things (IoT) and for high bandwidth-consuming scenarios such as virtual reality.

Another achievement that will be announced by Huawei at MWC 2015 is its 5G air interface architecture, which has proven capable of supporting the full duplex prototype technology featuring multi-path fading cancellation and large bandwidth. The test results show that this entirely new duplex mechanism is able to improve spectral efficiency by 200%, laying a solid foundation for future unification of TDD and FDD spectrums. As the leading innovator of next generation mobile technologies, Huawei has committed an investment of 600 million USD in research and innovation of 5G until 2018. Recently, Huawei appointed a team of over 300 5G experts and established nine 5G R&D centers worldwide. Huawei’s exciting breakthroughs in 5G innovation will once again boost the development of the future of mobile technologies.

Welcome to world of 2099

The world of 2099 will be unrecognisable from the world of today, but it can be predicted, says one visionary. ARTHUR GOLDSTUCK met him in Singapore.

Futuristic structures tower over the landscape. Giant, alien-looking trees light up with dazzling colours amid the hundreds of plant species that grow up their trunks. Cosmetic stores sell their wares via public touch-screens, with products delivered instantly in drawers below the screens.

This is not a vision of the future. It is a sample of Singapore today. But it is also an inkling of the world we may all experience in the future.

Singapore was the venue, last week, of the World Cities Summit, where engineers, politicians, investors and visionaries rubbed shoulders as they talked about the strategies and policies that would enhance urban living in the future.

As part of the Summit, global payment technologies leader Mastercard hosted a small media briefing by one of Singapore’s leading thinkers about the future, Dr Damian Tan, managing director of Vickers Venture Partners. The company’s slogan “We invest in the extraordinary,” offers a small clue to Tan’s perspective.

“We look as far forward as 2099 because, as a venture capital firm, we invest in the long term,” he tells a group of journalists from Africa and the Middle East. “Companies explode in growth because there is value in the future. If there is no growth, they won’t explode.”

The big question that the Smart Cities Summit and Mastercard are trying to help answer is, what will cities look like in the year 2099? Tan can’t give an exact answer, but he offers a framework that helps one approach the question.

“If you want to look at 81 years into the future, and understand the change that will come, you need to double that amount and look into the past. That takes us to 1856. The difference between then and now is the difference you can expect between now and 2099.”

Win a Poster Heater with Gadget and Takealot.com

This winter Gadget and Takealot.com are giving away three Poster Heaters, which look like posters but become heaters when you plug them in.

Published

on

Three Gadget readers will each win a unit, valued at R550 each. To enter, follow @GadgetZA and @Takealot on Twitter and tell us on the @GadgetZA account how many Watts the heater consumes.

What’s the big deal about these heaters? Many of us are struggling to keep the balance between soaring electricity costs and the need to keep warm this winter.

However, the recently launched Poster Heater by EasyHeat and distributed in South Africa by Takealot.com is not only one of the most cost effective electric heaters currently on the market, it is also easy to setup and use.

As the name indicates, it is a poster similar to one you would hang on a wall. But, plug it in and it turns into a 300 Watt heater. The Poster Heater isn’t designed to heat hallways or large rooms, but rather smaller ones like a bedroom or a baby’s nursery or a dressing room.

It uses radiant heating, which means that it heats up in a couple of minutes and the heat is directed at the objects or people around it, quickly taking the chill out of the air and providing a comfortable ambient temperature.

The other advantage of radiant heating is that it doesn’t dry out the air like infrared or gas heaters. Users also don’t have to worry about their children or pets getting too close to it because, even though it gets hot, it can be touched.

To enter the competition follow the steps below:

Competition entry details:

1. Follow @GadgetZA and @Takealot on Twitter. (We will ONLY be accepting entries via Twitter, so please don’t enter through the comments section of this article.)

2. Tell us on Twitter, via @GadgetZA, mentioning @Takealot in your posting, how many Watts the Poster Heater consumes.

cleardot.gif3. The competition closes on 31 July 2018.

4. Winners will be notified via Twitter on 1 August and Takealot.com will be in touch to organise delivery.

5. The competition is only open to South African residents.
