5G is a great enabler, but beware of its challenges

Published

on

By JACQUES VISSER, head of wireless at Vox

Digital transformation is rapidly changing the way in which we live, work, and play, and upcoming 5G technology will be crucial in providing the level of connectivity that will improve user experiences and expand broadband wireless services beyond mobile internet.

5G will stand on three primary pillars namely massive type communication, enhanced mobile broadband and ultra-reliable low latency communications. The biggest challenge is whether we will succeed in providing it at an affordable price to a broad base and beyond the already well-serviced metro areas. 

With its very low latency communication, the technology enables business use cases such as remote access for high availability sites, and mission-critical applications like medical equipment, augmented reality, Internet Protocol TV, and even connected self-driving cars. For the consumer market, this benefit will be especially appealing to gamers.

In addition, 5G is being seen as a true enabler of the Internet of Things, with applications in healthcare, retail, energy and utilities, industrial automation, intelligent buildings and infrastructure, and public safety and surveillance. 

We are optimistic that fixed-wireless “5G” services will be launched by late 2019, enabling operators to provide broadband services with the use of radio spectrum. With its high throughput, businesses – especially smaller ones that are more nimble – are likely to be the first adopters, with fixed-wireless 5G being used to link their internal corporate networks using solutions such as Software Defined Wide Area Networking (SD-WAN).

However, home users with dozens of connected devices – with family members surfing the web, streaming HD videos, playing online games, and making online voice and video calls – are unlikely to shift away from their existing fibre connections any time soon. As such, 5G is not going to replace fibre, but rather complement it, by giving users a high-speed, low-latency broadband connection even when they are on the move. In addition, business users can make use of multiple connection types – and even service providers – to ensure redundancy.

Getting from concept to mainstream

The industry is still waiting on a decision from the Independent Communications Authority of South Africa (Icasa) on what spectrum will be allocated for the use of 5G, but we are hoping that a decision will be made by the end of the year. 

While the 5G standards have yet to be finalised, there are only a limited number of bands which can be used, and a number of operators around the globe – and in SA – are already running trials. The most prominent band options currently under consideration are so-called low band below 2GHz, middle band 2GHz to 6Ghz and high band above 6 GHz.

Comsol Networks performed a proof of concept in Soweto on their 5G deployment in 2018, and achieved more than 1GBps throughput speed using the 28GHz spectrum, while Rain has recently announced at the Mobile World Congress (MWC) in Barcelona that they would roll out their 5G network in mid-2019. As a reseller of wireless connectivity services, Vox is monitoring these developments closely, and will seek to be involved once commercial services are launched.

It is expected that the Minister of Communications will provide the government’s policy guidelines with regard to the allocation of spectrum soon. This is a critical requirement to plan Mobile Network Operator (MNO) networks for 5G and to expand broadband services on 3G in rural areas. It is well known that some of the state-owned enterprises like Eskom and Transnet are in possession of fibre infrastructure running through rural areas, and there is an expectation from service providers in South Africa that the government will make this unproductive fibre available to provide broadband services in those areas. 

The required end-user devices will start appearing before long too; at the MWC, several manufacturers unveiled their 5G compatible smartphones and consumer premises equipment, which will become available in the market later in the year.

What can hold back widespread deployment?

There are still some major hurdles to the widespread deployment of 5G in South Africa, the biggest of which is the coverage area. Due to the frequencies being used, each base station can only cover a small area as compared to existing cellular technologies, meaning that there has to be a considerable investment in the rollout of additional base stations.

In addition, having a higher throughput needs to be matched with a backhaul link of similar capacity; with each 5G base station requiring up to a 10GBps connection, coverage will be restricted to areas with the fibre connectivity required to receive and transmit such large volumes of data.

It is likely that 5G coverage will initially be limited to areas where there is both a concentration of users, and the availability of fibre networks for backhaul – meaning city centres and other dense urban areas. Currently, it is not financially feasible for this technology to be deployed to smaller towns or rural areas.

Despite these challenges, there is a reason to be optimistic: South Africa ranks among the top 25 countries in the world in terms of quality of GSM networks, primarily as a result of having multinational telecommunications providers investing substantially in the country. Similarly, one can expect that the local commercial 5G networks, once up and running, will be of a world class standard too, ensuring that local users get to benefit from high-bandwidth, low latency connectivity that will fuel South Africa’s growth in the digital age.

Seedstars seeks tech to reverse land degradation in Africa

A new partnership is offering prizes to young entrepreneurs for coming up with innovations that tackle the loss of arable land in Africa.

Published

on

The DOEN Foundation has joined forces with Seedstars, an emerging market startup community, to launch the DOEN Land Restoration Prize, which showcases solutions to environmental, social and financial challenges that focus on land restoration activities in Africa. Stichting DOEN is a Dutch fund that supports green, socially-inclusive and creative initiatives that contribute to a better and cleaner world.

While land degradation and deforestation date back millennia, industrialization and a rising population have dramatically accelerated the process. Today we are seeing unprecedented land degradation, and the loss of arable land at 30 to 35 times the historical rate.

Currently, nearly two-thirds of Africa’s land is degraded, which hinders sustainable economic development and resilience to climate change. As a result, Africa has the largest restoration opportunity of any continent: more than 700 million hectares (1.7 billion acres) of degraded forest landscapes that can be restored. The potential benefits include improved food and water security, biodiversity protection, climate change resilience, and economic growth. Recognizing this opportunity, the African Union set an ambitious target to restore 100 million hectares of degraded land by 2030.

Land restoration is an urgent response to the poor management of land. Forest and landscape restoration is the process of reversing the degradation of soils, agricultural areas, forests, and watersheds thereby regaining their ecological functionality. According to the World Resources Institute, for every $1 invested in land restoration it can yield $7-$30 in benefits, and now is the time to prove it.

The winner of the challenge will be awarded 9 months access to the Seedstars Investment Readiness Program, the hybrid program challenging traditional acceleration models by creating a unique mix to improve startup performance and get them ready to secure investment. They will also access a 10K USD grant.

“Our current economic system does not meet the growing need to improve our society ecologically and socially,” says Saskia Werther, Program Manager at the DOEN Foundation. “The problems arising from this can be tackled only if a different economic system is considered. DOEN sees opportunities to contribute to this necessary change. After all, the world is changing rapidly and the outlines of a new economy are becoming increasingly clear. This new economy is circular and regenerative. Landscape restoration is a vital part of this regenerative economy and social entrepreneurs play an important role to establish innovative business models to counter land degradation and deforestation. Through this challenge, DOEN wants to highlight the work of early-stage restoration enterprises and inspire other frontrunners to follow suit.”

Applications are open now and will be accepted until October 15th. Startups can apply here: http://seedsta.rs/doen

To enter the competition, startups should meet the following criteria:

  • Existing startups/young companies with less than 4 years of existence
  • Startups that can adapt their current solution to the land restoration space
  • The startup must have a demonstrable product or service (Minimum Viable Product, MVP)
  • The startup needs to be scalable or have the potential to reach scalability in low resource areas.
  • The startup can show clear environmental impact (either by reducing a negative impact or creating a positive one)
  • The startup can show a clear social impact
  • Technology startups, tech-enabled startups and/or businesses that can show a clear innovation component (e.g. in their business model)

Also, a specific emphasis is laid, but not limited to: Finance the restoration of degraded land for production and/or conservation purposes; big data and technology to reverse land degradation; resource efficiency optimization technologies, ecosystems impacts reduction and lower carbon emissions; water-saving soil technologies; technologies focused on improving livelihoods and communities ; planning, management and education tools for land restoration; agriculture (with a focus on precision conservation) and agroforestry; clean Energy solutions that aid in the combat of land degradation; and responsible ecotourism that aids in the support of land restoration.

The dark side of apps

Published

on

Mobile device security threats are on the rise and it’s not hard to see why. In 2019 the number of worldwide mobile phone users is forecast to reach 4.68 billion of which 2.7 billion are smartphone users. So, if you are looking for a target, it certainly makes sense to go where the numbers are. Think about it, unsecured Wi-Fi connections, network spoofing, phishing attacks, ransomware, spyware and improper session handling – mobile devices make for the perfect easy target. In fact, according to Kaspersky, mobile apps are often the cause of unintentional data leakage.

“Apps pose a real problem for mobile users, who give them sweeping permissions, but don’t always check security,” says Riaan Badenhorst, General Manager for Kaspersky in Africa. “These are typically free apps found in official app stores that perform as advertised, but also send personal – and potentially corporate – data to a remote server, where it is mined by advertisers or even cybercriminals. Data leakage can also happen through hostile enterprise-signed mobile apps. Here, mobile malware uses distribution code native to popular mobile operating systems like iOS and Android to spread valuable data across corporate networks without raising red flags.”

In fact, according to recent reports, 6 Android apps that were downloaded a staggering 90 million times from the Google Play Store were found to have been loaded with the PreAMo malware, while another recent threat saw 50 malware-filled apps on the Google Play Store infect over 30 million Android devices. Surveillance malware was also loaded onto fake versions of Android apps such as Evernote, Google Play and Skype.

Considering that as of 2019, Android users were able to choose between 2.46 million apps, while Apple users have almost 1.96 million app options to select from, and that the average person has 60-90 apps installed on their phone, using around 30 of them each month and launching 9 per day – it’s easy to see how viral apps take several social media channels by storm.

“In this age where users jump onto a bandwagon because it’s fun or trendy, the Fear of Missing Out (FOMO) can overshadow basic security habits – like being vigilant on granting app permissions,” says Bethwel Opil, Enterprise Sales Manager at Kaspersky in Africa. “In fact, accordingly to a previous Kaspersky study, the majority (63%) of consumers do not read license agreements and 43% just tick all privacy permissions when they are installing new apps on their phone. And this is exactly where the danger lies – as there is certainly ‘no harm’ in joining online challenges or installing new apps.”

However, it is dangerous when users just grant these apps limitless permissions into their contacts, photos, private messages, and more. “Doing so allows the app makers possible, and even legal, access to what should remain confidential data. When this sensitive data is hacked or misused, a viral app can turn a source into a loophole which hackers can exploit to spread malicious viruses or ransomware,” adds Badenhorst. 

As such, online users should always have their thinking caps on and be more careful when it comes to the internet and their app habits including:

  • Only download apps from trusted sources. Read the reviews and ratings of the apps as well
  • Select apps you wish to install on your devices wisely
  • Read the license agreement carefully
  • Pay attention to the list of permissions your apps are requesting. Only give apps permissions they absolutely insist on, and forgo any programme that asks for more than necessary
  • Avoid simply clicking “next” during an app installation
  • For an additional security layer, be sure to have a security solution installed on your device

“While the app market shows no signs of slowing down, it is changing,” says Opil. “Consumers download the apps they love on their devices which in turn gives them access to content that is relevant and useful. The future of apps will be in real-world attribution, influenced by local content and this type of tailored in-app experience will lead consumers to share their data more willing in a trusted, premium app environment in exchange for more personalised experiences. But until then, proceed with caution.”
