Vodacom has implemented a full-stadium WiFi solution at Loftus Versfeld that will allow users to easily connect to the Internet – despite the large crowds.
Large crowds at sports matches can mean frustratingly slow uploads of status updates and selfies, and make it all-but-impossible to view the video instant replays that you get when watching the big game at home. Vodacom’s latest full-stadium Wi-Fi solution is an African first and heralds the introduction of the smart stadium where connectivity issues will be a thing of the past and fans get the best of both worlds.
Rugby fans visiting Loftus Versfeld will be able to connect to Vodacom’s new high-density Wi-Fi network, with faster data connectivity than ever before. The solution is the first step in making Loftus Versfeld Africa’s first truly ‘smart’ stadium.
“As the home of the Vodacom Blue Bulls and one of the most visited stadiums in South Africa, Loftus Versfeld was the obvious stadium for us to launch this project. Our engineers have been hard at work, installing more than 40 km of fibre and more than 400 Wi-Fi access points. We tested the service for the first time at the Bulls-Lions match on 2 May and were incredibly pleased with the result,” said Andries Delport, Vodacom’s Chief Technology Officer.
The key to the success of Vodacom’s Wi-Fi at Loftus Versfeld is the commercial implementation of EAP-SIM technology. This is the first time this technology, which stands for Extensible Authentication Protocol, will be employed in South Africa. It enables a seamless switch between radio bearers (4G, 3G, 2G and Wi-Fi), meaning that a cellphone or tablet will connect to whichever bearer has the best connection, ensuring the fastest possible data access. EAP-SIM also means that during a Wi-Fi data session it will still be possible to receive voice calls.
“An EAP-SIM network offers real benefits to our customers. On top of better speeds there’s no need to buy additional Wi-Fi bundles to connect to the network. Instead, data will be drawn directly from a customer’s existing data allocation, making the connection and usage process simple. Non-Vodacom customers will also be able to buy Wi-Fi bundles to gain access,” said Delport.
The network, which was built by Cisco Systems, is made up of hundreds of Cisco Wi-Fi access points. By increasing the number of access points and using Wi-Fi spectrum, the data carrying capacity within the stadium has been dramatically increased. This ultimately means faster downloads and uploads, and less congestion. The solution is flexible and Vodacom has plans to increase the number of access points to 700 in the future.
Michael Kämper, Director Mobility at Cisco Services EMEAR, had this to say about the project:
“Cisco Systems is proud to be associated with Vodacom in the first Cisco Connected Stadium Wi-Fi deployment in Africa. The combination of Vodacom’s market leadership in SA and Cisco’s global leadership for high-density Wi-Fi deployments is a winning combination.”
As the home of one of the most passionate rugby franchises in South Africa, the Blue Bulls are always exploring innovative ways to bring the ultimate gaming experience to their fans. More than just a solution to congestion, Barend van Graan, CEO of the Blue Bulls Company sees the solution as the first step to creating a next generation smart stadium that can enrich fan experience:
“At the moment, speeds in the majority of stadiums are not fast enough to stream video when a match is on and the network is congested. This can make watching content extremely frustrating. In some cases people would rather stay at home to watch the game on TV where they can easily view replays, see different camera angles or even catch games being played at other stadiums. Our new Wi-Fi network will change that. The ability to watch video content on their smartphones will give fans the opportunity to enjoy the vibe of being at a big game while at the same time enjoying the benefits that come from watching at home.
“One of the ways we plan to further add value to the stadium experience is via the Vodacom Rugby App. On top of being able to access exclusive content, location-based services will mean that in the future users will be able to access stadium specific promotions, have food and drinks delivered directly to their seats and even find out which bathrooms have less of a queue.”
Vodacom is currently in talks with other stadiums and public spaces, like shopping malls, to roll out the solution.

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