Sorry, can you give me a WiFi password?
If you have never asked this question or were not asked, it means that you are cut off from today’s world.
But if we begin to mention it from the beginning, WiFi was introduced in the market in 1997 as a system that was a source of wire access to the Internet in a particular place or area.
The WiFi word has come from the WiFi Alliance Organization, but now it has become so common that it has been included in the Royal Spanish Academy’s dictionary.
But that doesn’t mean. One of the company’s founding members, Phil Beljar, revealed that this was the result of a marketing strategy.
It is also important to know that WiFi is based on the standard of IEEE 802.11, a wireless connectivity system created by the Institute of Electrical and Electronics Engineers, a global organization. The organization works for quality and development in the technical sectors globally.
And for the past 25 years, WiFi has profoundly impacted the methods of communication in society, continuously improving its technology.
Swajit Day, director of the Center for Wireless Communication at the US University of Sean Diego, says’ Wi-Fi’s biggest impact and benefit is equal access to the Internet. Imagine that only the rich could have used it if the world only developed with cellular or satellite technology. ‘
All access to WiFi is possible because it is based on a non-licensed spectrum.
Professor Day says, “This means that no one controls it; of course, it means that sometimes the quality of his service can be bad.” This is a free network -a free network than a cable network. Without WiFi, millions of people around the world lose any Internet access.’
But WiFi also gives rise to economic effects.
Dorothy Stanley, a member of the Standards Association at the Institute of Electrical and Electronics Engineers, told BBC Mando that its economic impact is’ several billion dollars a year. This is an extraordinary effect. I think the effects of connectivity on people are less difficult to count. ‘
WiFi Alliance estimates that in 2022 active devices will use about 18 billion WiFi.
The global economic price of WiFi is estimated at US $ 3.3 trillion in 2021, while telecom research is expected to be the US $ 4.9 trillion by 2025.
WiFi also transformed its customers to a more efficient, reliable, and secure connection, hybrid or remotely working with complex connectivity systems and the Internet of Things (IoT).
In a rapidly connected world, we ask ourselves, what is the future of this connection? What comes after WiFi to access the Internet?
Access to networks networks
It is important to clarify that although WiFi has entered the developed world in the last two decades, there are still many areas where this technology is unavailable, and neither is Internet access available.
For example, according to a study by the Inter -American Institute for Cooperation on Agriculture (IICA) Inter -American Development Bank (IDB), and Microsoft 2021, it is estimated that there are 244 million people in Latin America, one-third of the population of the Internet. Don’t have access.
However, after the 19 pandemics, contact became an important requirement, and many technical promotions came from governments and organizations to connect to remote areas.
Dorothy Stanley, head of the Standard Task Force, says: ‘If WiFi is not a complete solution, it is an important part of the overall solution.’
Experts provide examples of remote areas of India and Canada in this regard, where satellite, fiber optics, and wireless communication systems are implemented.
“If we talk about future contacts, I think the short answer will be that it will improve and exacerbate and cover areas that do not fall under it today.”
He highlighted the efforts of Mexican City officials in this regard, saying that in 2021, thanks to the city’s 21,500 free internet points, he achieved the Guinness World Record of the most connected city in the world.
WiFi for now
Since the onset of WiFi, its quality has been steadily increasing. Usually, speed improvement, new features or technologies, and a new identity name have emerged.
The 802.11AX released in 2021, or the Wi-FI 6, is the latest version. It offers a fast pace of 9.6 GHBs (GBPS) and supports 2.4 GHz, 5, and 6 GHz frequency bands and wide channels.
But it is not yet widely available in the market.
And engineers have already been working with better features on 802.11BE, or Wi-FI 7, before 2024, which may prove to be a ‘major milestone’ according to the June 2022 task force report.
Everything indicates that WiFi has no limit.
“We have not yet received an alternative to it, and it is estimated that the demand for WiFi will increase by 10 times in the next 10 years, so we are seeing a rapid increase in WiFi,” says Stanley.
She adds: ‘I think we will see more WiFi in the coming days. Our goal is to focus on more range, performance and continue to compatibility with the earlier version because we want people to use all the devices they have already purchased and have spent money on them. ‘
Progress in WiFi not only improves speed but also allows many devices to be connected simultaneously and maintain it.
Speaking to Professor DBC Mando, he says, ‘More and more people want to use different types of devices. Not only the phone but the clock, the lens, etc. There will be more and more connected devices in the future. So WiFi keeps updating. ‘
Replacement of WiFi
Although WiFi still has enough room to grow and it is the most stable technology for connectivity, some alternatives to the Internet connection can be completed in the future or may replace it.
Sujit Day says 5G (5G) are coming to most European countries, the United States, and Latin America. The problem is that 5G was mostly based on 4G technology. Therefore, it will take a few years to implement 5G fully.
According to a study by the technology company Erickson, about 43 % of mobile subscriptions in Latin America will be at 5G by the end of 2026.
But the costs incurred on it will be high.
“Many people cannot afford a 5G plan, so WiFi is still the cheapest alternative to them,” says a professor at UCSD. But of course, you cannot take WiFi out of the house, so there should be a 5G plan that everyone can afford. ‘
The possibility of transmission of data is also being shown through light.
Edinburgh University Professor of Mobile Communications Herald Haas developed the term Li-Fi in 2011, a technology that uses LED lights to transmit data.
The negative aspect of the traditional WiFi routers is that they can interfere with each other by connecting multiple devices in one place.
But Wi-Fi’s creator says Lai-Fai can use several LED lights in a room without interference.
Wi-Fi can provide 100 times faster internet access than traditional WiFi, which offers a speed of 1 gig but a bit per second.
And it requires a light source, such as standard LED lamps or bulbs, an internet connection, and a photodetector.
According to Professor Day, this type of technology is very effective for the interior, but it will require an additional infrastructure cost, so it is not an inexpensive alternative.
Explaining the details, he says, ‘Imagine an office where you have to put the right reflection, it has some advantages in terms of speed and contact levels, but the disadvantages are the new terms for it. Infrastructure will be needed. ‘
And there is also an alternative through satellite.
Companies like the billionaire Elon Musk’s Star Link offer high-speed broadband satellite internet service at remote and rural locations with a $ 110 monthly plan, with a hardware device priced at the US $ 599.
Stanley says, ‘Star Link is a modern addition to our connectivity portfolio. I think it has the ability to increase the current satellite deployment and make this technology more affordable and wider. ‘
However, satellite communication is delayed, which means the delay is higher than WiFi or cell phones.
Professor Day says, ‘To reduce this problem, some companies have low orbit satellite and fewer interval problems. Now they are also trying to connect satellite and WiFi.
“If this merger is successful in the next few years, it will not be just a few people who will be able to work from afar. Many more people will be able to do so because there will be WiFi connectivity everywhere. ‘
Professor Day highlighted Google’s balloon project and some companies testing the drone to offer connectivity.
He warns: ‘I think the best contact will be from the air because it will cost the cost of infrastructure.’
“You can access areas where fiber optics are not, especially in backward countries that want to be more developed,” he says.
Google Globe may be the Internet access to remote areas.
Numerous technologies are currently being tested and will be used in the future.
Stanley says, ‘There is not a single technology that involves everything. Connectivity is so demanding that we need to take all things, keep the products together and bring them to the market so that people can meet the needs of being connected everywhere. ‘
They say, ‘ our vision for the future is that everyone is connected.’
For Professor Day, the connection scenario will completely change in the next 10 to 20 years, which is why ‘Connectivity must be a birthright in modern times.’
He finalized the matter and said: ‘Because we cannot do anything constructively without connectivity.’
