Vodacom has launched a Licensed Assisted Access (LAA) site on its live network at its Midrand campus and demonstrated speeds >650 Mbps using a commercial handset.
This is the first speed test on both a commercial LAA site and device in Africa and is also the fastest speed test ever achieved on a commercial LTE network and device in South Africa.
Vodacom’s LAA site is also believed to be the first time in South Africa where 4 component carrier (4CC) aggregation has been deployed on a live LTE network. The LAA site on Vodacom’s campus is configured to use a single 10 MHz carrier of Vodacom’s licensed 1800 MHz spectrum and 3 additional carriers each of 20 MHz unlicensed 5GHz spectrum. In addition to 4CC carrier aggregation, 4×4 MIMO (Multiple Input Multiple Output) technology was used for the 1800 MHz carrier and 256 QAM (Quadrature Amplitude Modulation) was activated on all carriers.
Using this configuration it was possible to achieve a peak download speed of up to 653Mbps on OOKLA using a commercial Motorola Z2 Force handset which is also considered to be the first commercial LAA device tested in South Africa.
Andries Delport, Vodacom Group’s Chief Technology Officer commented:
“Today’s launch of what we believe to be the continent’s first commercial LAA site and device and the impressive speeds demonstrates that Vodacom continues to lead in technology innovation and enabling new possibilities for our customers. We have managed to launch new technologies such as LAA despite the severe constraints on spectrum that we are facing in the country. Quite crucially, the latest speeds on the LAA network show that the single biggest contributor to mobile network performance is spectrum. Although we have demonstrated impressive LAA speeds using unlicensed spectrum, Vodacom still requires access to new, licensed spectrum for the practical rollout of similar high speed LTE services across the country. Licensed spectrum is the key to making these higher speeds available to all customers as it can be deployed across our extensive outdoor site footprint and is not limited to indoor and other small area deployments as is the case with LAA”.
LAA enables operators such as Vodacom to use unlicensed spectrum while co-existing with Wi-Fi by fair sharing of the unlicensed spectrum using Listen Before Talk (LBT) Technology. Innovative technologies such as LAA enable Vodacom to improve the network capacity and speeds in important indoor hotspot areas, and in the absence of much needed additional licensed spectrum. It is less suited to wide scale coverage on outdoor macro sites due to the poorer propagation characteristics of the unlicensed 5GHz band.
Vodacom will soon begin rolling out LAA to other sites on its live network, starting with important indoor hotspots such as airports, malls and office buildings. The availability and pricing for LAA capable handsets will be communicated as the rollout has progressed.
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.
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:
3. 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.
