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.

Low-cost wireless sport earphones get a kickstart
Wireless earphone brands are common, but not crowdfunded brands. BRYAN TURNER takes the K Sport Wireless for a run.
As wireless technology becomes better, Bluetooth earphones have become popular in the consumer market. KuaiFit aspires to make them even more accessible to more people through a cheaper, quality product, by selling the K Sport Wireless Earphones directly from its Kickstarter page
KuaiFit has an app by the same name which offers voice-guided personal training services in almost every type of exercise, from cardio to weight-lifting. A vast range of connectivity to third-party sensors is available, like heart rate sensors and GPS devices, which work well with guided coaching.
The app starts off with selecting a fitness level: beginner, intermediate and advanced. Thereafter, one has the ability to connect with real personal trainers via a subscription to its paid service. The subscription comes free for 6 months with the earphones, and R30 per month thereafter.
The box includes a manual, a USB to two USB Type B connectors, different sized soft plastic eartips and the two earphone units. Each earphone is wireless and connects to the other independently of wires. This puts the K Sport Wireless in the realm of the Apple Earpods in terms of connection style.
The earphones are just over 2cm wide and 2cm high. The set is black with a light blue KuaiFit logo on the earphone’s button.
The button functions as an on/off switch when long-pressed and a play/pause button when quick-pressed. The dual-button set-up is convenient in everyday use, allowing for playback control depending on which hand is free. Two connectivity modes are available, single earphone mode or dual earphone mode. The dual earphone mode intelligently connects the second earphone and syncs stereo audio a few seconds after powering on.
In terms of connectivity, the earphones are Bluetooth 4.1 with a massive 10-meter range, provided there are no obstacles between the device and the earphones. While it’s not Bluetooth 5, it still falls into the Bluetooth Low Energy connection category, meaning that the smartphone’s battery won’t be drastically affected by a consistent connection to the earphones. The batteries within the earphones aren’t specifically listed but last anywhere between 3 and 6 hours, depending on the mode.
Audio quality is surprisingly good for earphones at this price point. The headset style is restricted to in-ear due to its small design and probable usage in movement-intensive activities. As a result, one has to be very careful how one puts these earphones, in because bass has the potential of getting reduced from an incorrect in-ear placement. In-ear earphones are usually notorious for ear discomfort and suction pain after extended usage. These earphones are one of the very few in this price range that are comfortable and don’t cause discomfort. The good quality of the soft plastic ear tip is definitely a factor in the high level of comfort of the in-ear earphone experience.
Overall, the K Sport Wireless earphones are great considering the sound quality and the low price: US$30 on Kickstarter.

Taxify enters Google Maps
A recent update to Taxify now uses Google Maps which allows users to identify their drivers, find public transport and search for billing options.
People planning their travel routes using Google Maps will now see a Taxify icon in the app, in addition to the familiar car, public transport, walking and billing options.
Taxify started operating in South Africa in 2016 and as of October 2018 operates in seven South African cities – Johannesburg, Ekurhuleni, Tshwane, Cape Town, Durban, Port Elizabeth and Polokwane.
Once riders have searched for their destination and asked the app for directions, Google Maps shares the proximity of cars on the Taxify platform, as well as an estimated fare for the trip.
If users see that taking the Taxify option is their best bet, they can simply tap on the ‘Open app’ icon, to complete the process of booking the ride. Customers without the app on their device will be prompted to install Taxify first.
This integration makes it possible for users to evaluate which of the private, public or e-hailing modes of transport are most time-efficient and cost-effective.
“This integration with Google Maps makes it so much easier for users to choose the best way to move around their city,” says Gareth Taylor, Taxify’s country manager for South Africa. “They’ll have quick comparisons between estimated arrival times for the different modes of transport, as well as fares they can expect to pay, which will help save both time and money,” he added.
Taxify rides in Google Maps are rolling out globally today and will be available in more than 15 countries, with South Africa being one of the first countries to benefit from this convenient service.
