A trustworthy virtual private network (VPN) is a good way to keep internet usage secure and private whether at home or on public Wi-Fi. Many users have long been familiar with various VPN services, which are necessary for the safe and free use of the internet without censorship restrictions. However, not all users who use VPN to unblock sites, know that some services cannot provide a high level of security on the internet. A VPN will navigate the information through a secure “tunnel” to hide them and encrypt communication travelling from and to the user’s device. However, a flaw in VPN encryption not only makes the VPN connection weak but also reduces the user's security and causes leaks.
A special report by Telecom Review 5G technical investigative team
As many operators around the globe have or are preparing to deploy and launch 5G networks and devices, the 3.5 GHz band has emerged as the de-facto band for most deployments, which has created economies of scale for devices and network equipment.
In the light of the coronavirus pandemic, and with fear that the virus might be spreading through cash money, many resorted to mobile money as an alternative means to execute transactions. Governments have been encouraging people to use digital payment methods to reduce person-to-person contact and curb the spread of the coronavirus. Mobile money is a very thriving industry in Africa with platforms such as Orange Money, M-Pesa and MTN’s MoMo, to name a few.
Operating systems (OS) are the interface with which users navigate their devices and are essential to the functioning of computers and smartphones. That’s why they form a major challenge for their designers in terms of customer loyalty, data flow control and ecosystem development.
5G, the greatest of all technologies, is in danger. Just like all other industries, telecommunications has been also affected by the Covid-19 pandemic and the most visible impact is the delay in the deployment of the fifth generation technology. All efforts made in the past couple of years and that were planned to see fruition in 2020 have been put on hold all over the world.
One of the keywords in the era of 5G is spectrum. Even though several use cases were developed and are trialed on a daily basis by leading operators and vendors and in spite of the fact that several operators have already launched the service, the issue of spectrum allocation still raises a dilemma. Despite Africa being quite behind in the race to 5G deployment, it has been calling for making spectrum available to expedite the development of the fifth generation technology.
Some may describe cybersecurity as “a bit like Alice in Wonderland” where you run as fast as you can only to stay in place. And today, if you wish to stay ahead of cyber criminals, you should run twice or ten times as fast as that.
Cybersecurity has risen to become a national concern as threats are taken now more seriously. Africa has been among the fastest growing regions in terms of cybercrime activities to the extent that the continent is considered as a source of significant cyberattacks targeting the rest of the world.
In 2019, it was made clear that blockchain is not just a hype but an exciting innovation that has gained momentum throughout the past couple of years to reach a not so bad level of adoption. New parties and companies have acknowledged it and a few central banks gave their green light even though a majority admits that they’re still trying to understand the technology. Africa’s stance on blockchain is remarkable in the sense that many countries have caught on the trend and are increasingly adopting cryptocurrencies.
The whole world is aware by now of the benefits of artificial intelligence and how it can transform businesses. A report commissioned by Microsoft and conducted by Ernst & Young on AI maturity in the Middle East and Africa region, found that at least 46% of South African companies are piloting artificial intelligence and are showing more and more interest in deploying the new technology.
