Mobile data traffic set to grow 55% a year in SA

Published

on

By 2020, mobile data traffic will grow nine-fold in South Africa, at a compound annual growth rate of 55%, according to the Cisco Visual Networking Index (VNI) Global Mobile Data Traffic Forecast (2015 to 2020)

Since 2000, when the first camera phone was introduced, the number of mobile users has quintupled globally. By 2020, mobile data traffic will grow nine-fold in South Africa, at a compound annual growth rate of 55%, according to the Cisco Visual Networking Index (VNI) Global Mobile Data Traffic Forecast (2015 to 2020).

Vernon Thaver, Chief Technology Officer at Cisco South Africa, asserts that “the increasing demand for network mobility is a key trend highlighted in this year’s forecast that represents significant opportunities for South African service providers today and in the immediate future. With Africa being a mobile hub, we are beginning to realise the immense potential that a variety of mobile services can offer. South Africa’s journey to digitisation is dependent on the growth of mobile and the necessity of ensuring that high speed internet is available not only in homes and offices but also public places like shopping centres. The findings highlight that service providers in South Africa have immense opportunities to innovatively deliver a variety of mobile services and experiences to consumers and business users as the Internet of Everything (IoE) continues to take shape.”

Key highlights within the report that will impact South Africa

The smart mobile device boom

The proliferation of mobile phones, including “phablets” (a hybrid blend of smartphone and tablet features), is increasing so rapidly that more people will have mobile phones (5.4 billion) than electricity (5.3 billion), running water (3.5 billion) and cars (2.8 billion) by 2020. In South Africa, 63% of mobile connections will be ‘smart’ connections by 2020, up from 22% in 2015.

Mobile video in the age of digitisation

Mobile video will have the highest growth rate of any mobile application. In South Africa, video will be 73% of mobile data traffic by 2020, compared to 52% at the end of 2015. Consumer and business users’ demand for higher video resolution, more bandwidth, and processing speed will increase the use of 4G connected devices. 4G connectivity share is projected to surpass 2G by 2018 and 3G by 2020.

Machine-to-Machine (M2M) Connections and Wearable Devices Continue to Rise

M2M refers to applications that enable wireless and wired systems to communicate with other devices of the same ability (e.g., GPS/navigation, asset tracking, utility meters, security/surveillance video, healthcare monitoring, etc.) In South Africa, M2M traffic will grow 24-fold from 2015 to 2020 to account for 8% of total mobile data traffic by 2020, compared to 3% at the end of 2015.

·         By 2020, M2M connections will represent 26.4 percent of mobile-connected devices—up from 7.7 percent in 2015.

·         Global wearables will grow six-fold from 2015 to 2020.

Connecting the country

By 2020:

·         In South Africa, 4G connections will grow 8-fold from 2015 to 2020, a compound annual growth rate of 50% and will account for 45.1% of total mobile data traffic by 2020, compared to 21.7% at the end of 2015.

·         Globally, total Wi-Fi hotspots, including home spots, will grow 7X from 2015 (64 million) to 2020 (432 million). Globally, home spots will grow from 57 million (2015) to 423 million (2020).

“With the ever-increasing billions of people and things that are being connected, mobility is the predominant medium that’s enabling today’s global digitization transformation. Future mobile innovations in cellular, such as 5G, and Wi-Fi solutions will be needed to further address new scale requirements, security concerns, and user demands. IoT advancements will continue to fuel tangible benefits for people, businesses, and societies,” says Thaver.

Money talks and electronic gaming evolves

Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.

The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.

The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games. 

It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.

MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.

“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”

New phenomena, often associated with the flavour of the moment, also emerge every year.

“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain unpacked

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.

Published

on

This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.

What is blockchain?

A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.

A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.

Each block stores:

–           A number of valid records or transactions.
–           Information referring to that block.
–           A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.

Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.

As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.

How is blockchain so secure?

Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.

Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.

In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.

What else can blockchain be used for?

Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.

Use of blockchain in healthcare

Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.

Use of blockchain for documents

Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.

Other blockchain uses

This technology could also revolutionise the Internet of Things  (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.

Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.

Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
