Vodacom LAA test gets 650Mbps on handset

Published

on

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.

When will we stop calling them phones?

If you don’t remember when phones were only used to talk to people, you may wonder why we still use this term for handsets, writes ARTHUR GOLDSTUCK, on the eve of the 10th birthday of the app.

Do you remember when handsets were called phones because, well, we used them to phone people?

It took 120 years from the invention of the telephone to the use of phones to send text.

Between Alexander Graham Bell coining the term “telephone” in 1876 and Finland’s two main mobile operators allowing SMS messages between consumers in 1995, only science fiction writers and movie-makers imagined instant communication evolving much beyond voice. Even when BlackBerry shook the business world with email on a phone at the end of the last century, most consumers were adamant they would stick to voice.

It’s hard to imagine today that the smartphone as we know it has been with us for less than 10 years. Apple introduced the iPhone, the world’s first mass-market touchscreen phone, in June 2007, but it is arguable that it was the advent of the app store in July the following year that changed our relationship with phones forever.

That was the moment when the revolution in our hands truly began, when it became possible for a “phone” to carry any service that had previously existed on the World Wide Web.

Today, most activity carried out by most people on their mobile devices would probably follow the order of social media in first place – Facebook, Twitter, Instagram and LinkedIn all jostling for attention – and  instant messaging in close second, thanks to WhatsApp, Messenger, SnapChat and the like. Phone calls – using voice that is – probably don’t even take third place, but play fourth or fifth fiddle to mapping and navigation, driven by Google Maps and Waze, and transport, thanks to Uber, Taxify, and other support services in South Africa like MyCiti,  Admyt and Kaching.

Despite the high cost of data, free public Wi-Fi is also seeing an explosion in use of streaming video – whether Youtube, Netflix, Showmax, or GETblack – and streaming music, particularly with the arrival of Spotify to compete with Simfy Africa.

Who has time for phone calls?

The changing of the phone guard in South Africa was officially signaled last week with the announcement of Vodacom’s annual results. Voice revenue for the 2018 financial year ending 31 March had fallen by 4.6%, to make up 40.6% of Vodacom’s revenue. Total revenue had grown by 8.1%, which meant voice seriously underperformed the group, and had fallen by 4% as a share of revenue, from 2017’s 44.6%.

The reason? Data had not only outperformed the group, increasing revenue by 12.8%, but it had also risen from 39.7% to 42.8% of group revenue,

This means that data has not only outperformed voice for the first time – as had been predicted by World Wide Worx a year ago – but it has also become Vodacom’s biggest contributor to revenue.

That scenario is being played out across all mobile network operators. In the same way, instant messaging began destroying SMS revenues as far back as five years ago – to the extent that SMS barely gets a mention in annual reports.

Data overtaking voice revenues signals the demise of voice as the main service and key selling point of mobile network operators. It also points to mobile phones – let’s call them handsets – shifting their primary focus. Voice quality will remain important, but now more a subset of audio quality rather than of connectivity. Sound quality will become a major differentiator as these devices become primary platforms for movies and music.

Contact management, privacy and security will become critical features as the handset becomes the storage device for one’s entire personal life.

Integration with accessories like smartwatches and activity monitors, earphones and earbuds, virtual home assistants and virtual car assistants, will become central to the functionality of these devices. Why? Because the handsets will control everything else? Hardly.

More likely, these gadgets will become an extension of who we are, what we do and where we are. As a result, they must be context aware, and also context compatible. This means they must hand over appropriate functions to appropriate devices at the appropriate time. 

I need to communicate only using my earpiece? The handset must make it so. I have to use gesture control, and therefore some kind of sensor placed on my glasses, collar or wrist? The handset must instantly surrender its centrality.

There are numerous other scenarios and technology examples, many out of the pages of science fiction, that point to the changing role of the “phone”. The one thing that’s obvious is that it will be silly to call it a phone for much longer.
