20 years ago, with the release of 802.11b, Wi-Fi began its conquest of the world networking scene in earnest. Wi-Fi can easily be called out as one of the most popular technologies of the last two decades. Just as mobile telephony and mobile internet, it has become a part of everyday life. And with the advent of IoT and the introduction of 5G, the time has come for the new standard – Wi-Fi 6.
Beyond being significantly faster than the previous generation, Wi-Fi 6 delivers up to four times greater capacity. Latency is vastly improved, allowing for near real-time use cases. Wi-Fi 6 is also easier on connected devices’ batteries.
So what impact will Wi-Fi 6 have on business in the coming years?
Digitisation, mobility and IoT are driving the need for connectivity. By 2022, more IP traffic will cross global networks than in all prior ‘internet years’ combined up to the end of 2016. In other words, more traffic will be created in 2022 than in the 32 years since the internet started. In 3 years, 28 billion devices will be connected to the Internet, many of which (robots, production lines, medical devices) will communicate over a wireless network. Against this background, it is easy to understand why we need a redesigned wireless standard that is more responsive to present and future challenges.
Wi-Fi 6: The business impact
“In the first phase, we expect the new wireless standard to gain a significant foothold in the B2B field, where it brings important innovations,” said Garsen Naidu, Country Manager, Cisco South Africa. “We will see it, together with other technologies, penetrate significantly into manufacturing, into the logistics industry. The technology is also more effective in high-density settings like large lecture halls, stadiums and conference rooms, so we are likely to see significant penetration in these settings too. And, with its extremely low latency, Wi-Fi 6 also promises to open up new opportunities in AR/VR, healthcare, and self-driving vehicles. ”
Ever since the launch of the Internet, every leap in network speed has had a major impact on technological innovation: 4G has brought along the age of smartphones, whilst 5G and Wi-Fi 6 will transform the business world. According to Cisco experts, these two technologies – 5G and Wi-Fi – will be widely adopted at the same time, complementing each other.
A short history of Wi-Fi
In 1999, half a dozen technology companies, including Aironet, which was later acquired by Cisco, formed the Wireless Ethernet Compatibility Alliance. The standard announced that year, 802.11b, which gained significant commercial traction, was the first to emerge under the ‘Wi-Fi’ brand. As such, 1999 marks the year in which Wi-Fi really began.
Solutions that carry the official Wi-Fi logo work consistently with the IEEE 802.11 data transfer standard. These solutions are certified by the Wi-Fi Alliance, which guarantees compatibility between various wireless devices. In addition, networking manufacturers have done a lot to improve compatibility. Launched as early as 2002, Cisco Compatible eXtensions is a free licensing program that has enabled other vendors’ Wi-Fi products to be securely deployed on Cisco wireless networks.
Subsequent developments in Wi-Fi technology included managing interference and increasing data stability. Cisco is supporting these with the Cisco Flexible Radio Assignment and Cisco CleanAir technologies. The latter is capable of identifying and graphically displaying radio interference, identifying the source of the problem, and directing users to other, less crowded, channels.
Challenges of the present and opportunities for the future
One of the most widespread business applications of wireless technology is office Wi-Fi. Using Wi-Fi, employees can move freely and access the network from anywhere where there is a hotspot. Wi-Fi-based analysis and location services are also becoming increasingly popular. And with the spread of IoT, Wi-Fi is becoming ubiquitous, and is today found everywhere from agricultural fields to production lines.
“We see promising business opportunities and a wide range of new applications. At the same time, with hundreds and thousands of new devices connecting to wireless networks, IT teams are facing increasing complexity. So we need to rethink IT architectures from the ground-up,” added Naidu.
Much of this need to rethink network architectures is driven by the enormous growth in wireless connectivity.
Wi-Fi has driven growth in general IT use, which in turn has led to the need to provide and run bigger and more complex networks with a greater variety of endpoint device types on them. This complexity ‘feedback loop’, driven in no small part by Wi-Fi, requires that new solutions are developed to deal with this complexity.
Cisco has pioneered in this area, using AI, machine learning, and machine reasoning, via products such as Cisco DNA Assurance to eliminate manual troubleshooting and reduce the time spent resolving service issues.
The latest Wi-Fi 6 developments introduced earlier this year make a consistent, efficient and seamless wireless connectivity experience a reality.
Small SA town goes smartphone-only
Vodacom partners with farming business to upgrade all residents of Wakkerstroom from 2G devices to smartphones
All residents of the small town of Wakkerstroom, which straddles Mpumalanga and kwaZulu-Natal provinces, have had their 2G feature phones upgraded to 3G devices.
The initiative is a result of Vodacom partnering with BPG Langfontein, a farming business that employs the majority of the people living in Wakkerstroom. It is now the first smartphone-only town in South Africa. This is a model the network provider says it hopes to replicate across the country as part of its mission to connect people who live in deep rural areas and are still dependent on 2G networks.
Wakkerstroom, is the second oldest town in Mpumalanga province, on the KwaZulu-Natal border, 27 km east of Volksrust and 56 km south-east of Amersfoort.
“There are growing expectations for big corporates the size of Vodacom to serve a social purpose, and for us to use our resources and core capabilities to make a significant contribution in transforming the lives of ordinary people,” says Zakhele Jiyane, Managing Executive for Vodacom Mpumalanga. “We are helping to remove communication barriers, so that citizens in the area can be part of the digital revolution and reap the associated benefits. By moving the more than 1400 farm workers from 2G to 3G devices, this will also free much needed spectrum and this spectrum can be re-farmed to provide for faster networks such as 3G and 4G.
“Crucially, the move opens a new world of connectivity for farm workers in Wakkerstroom. As a result, most people in the area will now be able to use the Vodacom network to connect on the net and access online government services, eHealth services such as Mum&Baby and eCommerce. Learners can now surf the internet for the first time and access Vodacom’s eSchool free of charge and those who are actively looking for jobs can start using their smartphones and tablets to apply for jobs over the internet on Vodacom’s zero-rated career sites. This will be key for driving growth to the benefit of people living in this area.”
Vodacom has already deployed 4G base stations in Wakkestroom as part of this initiative.
For the next phase of this project, says Vodacom, it is going to educate the farm workers about data and the benefits of the Internet. Vodacom will also look at various ways in which it can help empower members of this community in areas of education, gender-based violence and health.
Facebook fact-checking goes to 10 more African countries
Facebook today announced the expansion of its Third-Party Fact-Checking programme to 10 additional African countries, which now join Kenya, Nigeria, South Africa, Cameroon and Senegal in the project,
In partnership with Agence France-Presse (AFP), the France 24 Observers, Pesa Check and Dubawa, this programme forms part of its work in helping assess the accuracy and quality of news people find on Facebook, whilst reducing the spread of misinformation on its platform.
Working with a network of fact-checking organizations, certified by the non-partisan International Fact-Checking Network, third-party fact-checking will now be available in Ethiopia, Zambia, Somalia and Burkina Faso through AFP, Uganda and Tanzania through both Pesa Check and AFP, Democratic Republic of Congo and Cote d’Ivoire through the France 24 Observers and AFP, Guinea Conakry through the France 24 Observers, and Ghana through Dubawa.
Feedback from the Facebook community is one of many signals Facebook uses to raise potentially false stories to fact-checkers for review. Local articles will be fact-checked alongside the verification of photos and videos. If one of our fact-checking partners identifies a story as false, Facebook will show it lower in News Feed, significantly reducing its distribution.
Kojo Boakye, Facebook Head of Public Policy, Africa, said: “The expansion of third-party fact-checking to now cover 15 countries in a little over a year shows firsthand our commitment and dedication to the continent, alongside our recent local language expansion as part of this programme. Taking steps to help tackle false news on Facebook is a responsibility we take seriously, we know misinformation is a problem, and these are important steps in continuing to address this issue. We know that third-party fact-checking alone is not the solution, it is one of many initiatives and programmes we are investing in to help to improve the quality of information people see on Facebook. While we’ve made great progress, we will keep investing to ensure Facebook remains a place for all ideas, but not for the spread of false news.”
When third-party fact-checkers fact-check a news story, Facebook will show these in Related Articles immediately below the story in News Feed. Page Admins and people on Facebook will also receive notifications if they try to share a story or have shared one in the past that’s been determined to be false, empowering people to decide for themselves what to read, trust, and share.
Providing fact-checking in English and French across eight countries, Phil Chetwynd, AFP Global News Director said: “AFP is delighted to be expanding its fact-checking project with Facebook. We are known for the high quality of our journalism from across Africa and we will be leveraging our unparalleled network of bureaus and journalists on the continent to combat misinformation.”
Eric Mugendi, Managing Editor from Pesa Check who will provide fact-checking services in Swahili and English added: “Social networks like Facebook haven’t just changed how Africans consume the news. Social media is often the primary access to digital content or the ‘Internet’ for many Africans. They shape our perceptions of the world, our public discourse, and how we interact with public figures. This project helps us dramatically expand our fact-checking to debunk claims that could otherwise cause real-world harm. The project helps us respond more quickly and directly. We’re seeing real positive results in our interactions with both publishers and the public itself. The project also helps our fact-checks reach a far larger audience than we would otherwise. This has helped us better understand the information vacuum and other viral dynamics that drive the spread of false information in Africa. Our growing impact is a small but tangible contribution to better informed societies in Africa.”
Caroline Anipah, Programme Officer, Dubawa (Ghana) said: “Dubawa is excited to be in Ghana where the misinformation and disinformation have become widespread as a result of technological advancement and increasing internet penetration. Dubawa intends to raise the quality of information available to the public with the ultimate aim of curbing the spread of misinformation and disinformation and promoting good governance and accountability.”
Derek Thomson, editor-in-chief of the France 24 Observers, said: “Our African users are constantly sending us questionable images and messages they’ve received via social media, asking us ‘Is this true? Can you check it?’ It’s our responsibility as fact-checking journalists to verify the information that’s circulating, and get the truth back out there. Participating in the Facebook programme helps ensure that our fact-checks are reaching the people who shared the false news in the first place.”
