IoT barriers fall in SA

The key barriers to entry in the IoT space – battery power and cost – have fallen away with the arrival in South Africa of revolutionary low-cost, low-power solutions.

“While machine to machine (M2M) solutions have been in use in some sectors in South Africa for several years, many industries and small- to mid-sized businesses have not been able to harness the potential of IoT due to data costs, complexity, and critically – the battery power required to run the devices,” says Neil Hamilton, VP for Business Development of international low power IoT specialists Thingstream.

Thingstream, now expanding into South Africa via a local partner network, delivers a global IoT connectivity platform which connects via GSM networks using a unique combination of MQTT and USSD messaging protocols. “The beauty of this new technology extends beyond cost-saving,” says Hamilton. “Its simplicity and low power consumption is making it a compelling proposition or where IoT devices might be dispersed across a vast geographic area or situated in inaccessible locations. Because a low-power IoT field unit might need a new battery only every five years, low-power IoT systems become a feasible option for sectors such as agriculture, forestry, mining and logistics.”

Hamilton expects significant adoption of low-power IoT systems in South Africa, based on the reception Thingstream has received since its arrival in the country earlier this year. “Many companies have been waiting for the right IoT solutions to arrive, and we see massive opportunities for IoT growth in the country, as well as across Africa,” he says.

Sectors showing particular interest include vehicle tracking firms looking to update and reduce the cost of their existing systems; the manufacturing sector; and supply chain and logistics firms seeking enhanced security and more efficient supply chain and asset management.  In addition, other new business cases are appearing practically weekly,” he says.

By 2025, more than 100 billion Internet of Things connected devices are predicted to be live, generating an overall revenue of close to $10 trillion, says Hamilton. This unprecedented growth looks poised to continue globally over the next few years, he says, with Africa moving quickly to leapfrog legacy technologies and capitalise on IoT’s potential too.

According to IDC, the Middle East and Africa (MEA) IoT market is set to grow 15% year on year, reaching $6.99 billion in 2018 and $12.62 billion by 2021, led by the manufacturing, transportation, and utilities industries.

“Everyone is excited about the business innovation low-power, low-cost IoT can enable, and Thingstream is now providing this revolutionary boxed connectivity to enable businesses to deploy more IoT devices, faster and more cost effectively,” he says.

Thingstream, building on parent company Myriad Group’s legacy of USSD expertise, harnesses the ubiquitous GSM network to deliver simple and secure IoT connectivity with international coverage and mobility, even in areas and sectors lacking internet connectivity. With out-of-the-box coverage in South Africa, no cross-border roaming costs and a fixed monthly cost as low as only $1 for 10,000 IoT messages, Thingstream makes IoT available to any size business.

Thingstream is fast growing its channel partner network in South Africa, collaborating with a range of partners who have existing large customer bases keen to harness IoT to reinvent and optimise their businesses.

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.
