What is wi-fi and how does it work ?
Appeared for the first time in 1997, the wireless network continues to evolve and continuously develops each year.
What does the term Wi-Fi mean ?
Wi-Fi expression comes from the contraction of two English words: Wireless and Fidelity that one can translate by “wireless fidelity”. Wi-Fi is currently possessed by Wi-Fi Alliance (formerly Wireless Ethernet compatibility alliance). This technology is a Set of wireless communication protocols governed by group standards IEEE 802.11.
We also find, depending on the country, the term Wlan (Wireless Local Area Network or Wireless Local Network in French) which also designates a Wi-Fi network.
How it works ?
L’wireless Internet Allows you to connect to the Internet without having to connect your PC to a cable. It is, indeed, through Short radio waves (from 2.4 to 5 GHz frequency), that all your equipment (computer, tablet, smartphone, etc.) are connected to your box. These radio waves thus allow the transmission of data from your devices to your box within your Wi-Fi network. Then here is the wireless network:
- The wireless network adapter of your connected device converts your digital data into radio signal;
- The information is transmitted via an antenna to your internet box;
- Your modem decodes the radio signal;
- The information requested is then sent to the Internet via a wired connection (Ethernet cable).
Also note that the traffic is bidirectional. This indicates that the Internet also transports data to your modem to be deciphered in radio signal. The latter is then received by the network adapter of your connected device.

802.11 at WiFi 6: Zoom on the different standards
Since its birth in 1997, Wi-Fi has been evolving and developing to offer more and more innovations.
What is a Wi-Fi standard ?
A Wi-Fi standard can be assimilated to a Wi-Fi version. Thus, with each revision of Wi-Fi, a new standard is created to allow users to know the Wi-Fi version that they use. She determines a Set of Wi-Fi characteristics different from the previous version. Since 1999, Wi-Fi standards were made up of a series of letters and figures placed after the word “Wi-Fi” as the standard “WiFi 802.11a “. Then in 2009, the consequences of figures and letters were replaced by a single figure. That year, the Wi-Fi standard “WiFi 802.11n “went to the standard” WiFi 4 “.
Wi-Fi standards history to the new WiFi 6 standard
Several Wi-Fi standards followed one another until the arrival of “WiFi 6” in 2019. During their appearances, each of them was able to bring its share oftechnological developments.
| Wi-Fi standard | Name | Release date | Frequencies | Maximum theoretical flow | Scope |
|---|---|---|---|---|---|
| 802.11 | / | 1997 | 2.4Ghz | 2 Mbps | 20 m |
| 802.11b | WiFi 1 | 1999 | 2.4Ghz | 11 Mbps | 35 m |
| 802.11a | WiFi 2 | 1999 | 5 GHz | 54 Mbps | 35 m |
| 802.11g | WiFi 3 | 2003 | 2.4Ghz | 54 Mbps | 38 m |
| 802.11n | Wifi 4 | 2009 | 2.4 GHz or 5 GHz | 72.2Mbps – 450Mbps | 70 m |
| 802.11ac Wave 1 | WiFi 5 | 2014 | 5 GHz | 866.7Mbps | 35 m |
| 802.11ac Wave 2 | WiFi 5 | 2016 | 5 GHz | 1.73 Gb/s | 35 m |
| 802.11ax | Wifi 6 | late 2019 | 2.4 GHz or 5 GHz | 2.4 Gb/s | N / A |
Summary table of the main Wi-Fi standards since 1997
Wi-Fi 6: What is it ?
There IEEE 802.11ax (also called WiFi 6) is the latest certified Wi-Fi technology standard. Its deployment has taken place since 2020 and its operation is similar to the previous Wi-Fi standards. However, WiFi 6 offers much more interesting flows and also brings several profits to its users.
Wifi 6: What changes compared to the latest WiFi 5 standard ?
The WiFi 6 standard brings some rather profitable developments to its users such as:
- a much faster connection speed with better descendant and uprights. If we compare with the previous standard (WiFi 5), the theoretical digital data transmission speeds are 40 % higher;
- more optimal management of multiple and simultaneous use of your connected devices. WiFi 6 makes it possible to divide pre-existing Wi-Fi channels into several sub-scanning capable of transporting data without causing interference;
- a more efficient connection in dense areas. If you live in a highly populated area, WiFi 6 could provide a solution to connection slowdowns;
- A Lighting the lifespan of your batteries By integrating a new system, the TWT (Target Wake Time). The latter allows to stand up the communication between your internet box and your devices connected to the wireless network when you do not use them;
- a Better preservation of your personal data. The new standard brings WPA3 costing which is the most effective costing currently. It provides more security when you surf the internet and thus protect your data;
- a Introduction of the maximized Wi-Fi signal. The 802 standard.11 AX, incorporates a new feature that allows your connected devices to use your bandwidth more optimally. It makes it Compatible with the connected house system And it will be possible to connect more devices without losing in connection speed thanks to better penetration of walls and obstacles. You can also increase the scope of your modem and therefore improve your Internet connection.
It is necessary to equip yourself with an adapted internet box or add an additional option (if your box is compatible) to your ISP to be able to benefit from the advantages of WiFi 6.

Wi-Fi: Standards, flow, range and safety
With the multiplication of connected objects within homes, starting with computers, smartphones and other tablets, Wi-Fi is everywhere. And for good reason, it allows Connect to wireless internet. Wi-Fi was created in 1999. Since then, he continues to evolve. So what are the different standards ? What are the flow rates and scope of the Internet in Wi-Fi ? But also how to improve your wireless internet connection or to secure your Wi-Fi network ? Degrouptest brings you some answers.
What is wi-fi ?
Let’s start with a development: we don’t say Wi-Fi but Wi-Fi. And, according to the consortium formed by six manufacturers of telecommunications equipment which filed the Wi-Fi brand in 1999, it is not written Wi-Fi, or even WiFi or WiFi but Wi-Fi.
Now that things are clear, what is wi-fi? Wi-fi is the English abbreviation to say Wireless Fidelity, wireless loyalty in French. To put it simply, Wi-Fi is Wireless Internet. Very practical, this technology is revolutionizing the use of the Internet in homes. Because, to connect to the Internet, no need an Ethernet cable in RJ 45. Indeed, Wi-Fi uses radio frequency bands to issue a signal transmit data through a network. These same data are then decoded and then received by a computer, a smartphone, a tablet or any other connected object.
What are the different Wi-Fi standards and what are their characteristics in terms of flow and range ?
Wi-Fi is a set of wireless communications protocols meeting IEEE 802 standards.11. These are determined by the Institute of Electrical and Electronics Engineers (IEEE) and define three parameters:
- Signal power : it is the speed of information transfer which is evaluated in bits/second. It decreases as we move away from the issuing source.
- The signal scope, as well as its obstacle resistance.
- The frequency on which the signal diffuses. For information, the higher a frequency, the more it allows you to pass information quickly. On the other hand, the higher the frequency, the lower the signal scope,.
Since the creation of Wi-Fi, in 1999, these IEEE 802 standards.He keep evolving. And you will see that The quality of the wireless internet in Wi-Fi has improved exponentially.
Current Wi-Fi standards
Today, no internet boxes work with Wi-Fi 1, 2, 3 and 4 standards. Because, since then, there have still been new ones:
Appeared in 2014 and improved in 2016, it is still used by Entry -level internet box of operators. Thanks to the appearance of beamforming, which allows the signal to be oriented to connected devices, from MU-MIMO (4 flows), which allows a Wi-Fi router to communicate simultaneously with several devices, and a bandwidth of 160 MHz, the maximum theoretical flow rate in Wi-Fi goes to 7 GB/S. Nevertheless, he only uses the 5 GHz band. Result: its range is only 35 meters.
Appeared in 2019 and compatible with the two frequency bands 2.4 GHz and 5 GHz, it has a better range than Wi-Fi 5, of the order of 70 meters. In addition, thanks to OFDMA, a technique that makes it possible to divide the Wi-Fi channel when it communicates with several devices, and to the improvements made to MU-MIMO technology (8 flows), it allows you to pass the flow theoretical maximum in Wi-Fi up to 10.5 Gb/s, a 40% increase in Wi-Fi flow.
In addition, he can Manage a large number of connected devices at the same time without slowing performance. Last advantage of Wi-Fi 6: the Smart wi-fi, That is to say that it automatically positions devices on the best frequency band. On the internet box market, it is today The most widespread Wi-Fi.
He appeared in 2021 and team today only premium internet boxes. It takes up all the characteristics of Wi-Fi 6. But, in addition, he uses a third Wi-Fi frequency band, with a bandwidth of 500 MHz in the 6 GHz. This is the largest spectrum allowance and it almost triples the spectrum available for Wi-Fi.
Thanks to this foray into the 6 GHz band, Wi-Fi connectivity crosses a new level, with more capacities, wider channels and less interference. With this evolution of Wi-Fi, it is therefore possible to have An even more efficient, more stable wireless internet network with an even higher speed, With a theoretical maximum of 11 GB/S. It is to this day the fastest Wi-Fi. Nevertheless, to take advantage of it, you have to be equipped with a compatible device.
Principles characteristics of Wi-Fi standards
| Speed | Scope | Frequencies | |
| Wi-Fi 5 | Up to 7 Gb/s | 35 meters | 5 GHz |
| Wi-Fi 6 | Up to 10.5 Gb/s | 70 meters | 2.4 GHz, 5 GHz |
| Wi-Fi 6th | Up to 11 Gb/s | 70 meters | 2.4 GHz, 5 GHz, 6 GHz |
Wi-fi flow that can be achieved with each Wi-Fi standard is a maximum theoretical speed. The real flow, from which the subscriber really benefits, as well as the signal signal, can vary enormously, and it is not to say it ! It’s time to take stock of your situation and Know your Wi-Fi flow.
Wi-Fi 7: the upcoming Wi-Fi standard
Even though a limited number of connected and internet boxes are compatible Wi-Fi 6th, we are already talking about Wi-Fi 7. With him, it will be possible toUse two frequency bands simultaneously, Unlike intelligent Wi-Fi which automatically positions devices on the best frequency band. With consequence: even faster flows thanks to thefrequency aggregation.
Old Wi-Fi standards
When it was launched in 1999, Wi-Fi complies with the IEEE 802 standard.11. It only uses the 2.4 GHz band, with a range of 35 meters. At the time, to give you an idea in terms of speed, this standard allows a transmission speed of 11 Mbit/s. It’s the Wi-Fi 1.
The same year, this standard was first evolved. It’s the Wi-Fi 2 (802.11a) which uses the 5 GHz band and allows you to have a Wi-Fi flow of 54 MB/s. Then in 2003, return to the 2.4 GHz band. And, if the Wi-Fi flow does not change, the signal range goes to 38 meters. It’s the Wi-Fi 3 (802.11g).
Then, until 2009, Wi-Fi standards do not evolve. Until the appearance of Wi-Fi 4 (802.11n). With MIMO technology (multiple input, multiple output) and a bandwidth lined with the association of the two frequency bands 2.4 GHz and 5 GHz, it allows you to have a theoretical speed in Wi-Fi of 450 MB/ s and has a range of 70 meters.
How to connect to Wi-Fi ?
To connect to the Internet in Wi-Fi, you must first activate Wi-Fi and then connect to a network. But, you will that the procedure is not the same depending on whether you have a device that runs on Android or iOS.
Open the parameter application on your device and press network and internet, then internet. A list of available Wi-Fi networks then appears. Press a network in the list. And, if necessary, if the one you select is veroused, between the network password.
On the home screen, go to settings and activate the Wi-Fi option. Your device then automatically searches for Wi-Fi networks available. Tap the name of the Wi-Fi network to which you want to connect. To access the network, you may need to enter the network password.
Once you are connected to Wi-Fi on your tablet or smartphone, the Wi-Fi symbol then appears at the top right of your device. On a computer that runs under Windows or iOS, it’s the same. But, to activate Wi-Fi and connect to a network, you can also directly from a shortcut which is on your screen, bottom right for a PC, at the top right for a Mac.
Bouygues Télécom voted best operator in wi-fi
In 2022, for the second consecutive year, Bouygues Telecm was elected best operator in Wi-Fi by the Wi-Fi barometer of NPERF. In terms of wireless internet, according to NPERF, Bouygues Telecom delivers an average download rate of 241 MB/s, almost 40% higher than that of its competitors. It is also he who, in Wi-Fi, delivers the best uprights, has the best latency, as well as the best web browsing and the best video streaming. It’s very simple, Bouygues Telecom comes to the top of all indicators.
How to secure your wireless network ?
A Wi-Fi network is like a house, you have to swarm it to prevent intruders from entering and spares misadventures. Indeed, securing your Wi-Fi network allows you to be the only one to be able to use it and also allows you to protect yourself from hacking or any other malicious act.
You can first change the name of your Wi-Fi network to make it unidentible, make it invisible from others by removing it visible access points, or choosing a password Strengthen.
But, above all, you can encrypt the data with a WEP safety key. Even more effective, and more reliable, the WPA key, which is also a data encryption system. There is finally the Wps, which is still another network safety standard that simplifies the peripheirical connection protocol to a wireless internet network.
To secure your Wi-Fi network, you can finally make sure you can use it. That is to say that when you receive family or friends at home and they want to connect to Wi-Fi, rather create a Guest Wi-Fi network rather than giving them access to your network by giving them your password.
How to change your Wi-Fi password ?
When you subscribe to an internet box, your operator provides you with a password to connect to Wi-Fi. It is noted on a label, and, very often, it is an interminable suite of numbers, letters, with or without capital letters, and special characters. They are impossible to remember. This is why it is advisable to change your wi-fi password and choose a known of yourself alone and impossible to find.
To do so, you have to connect to theInterface for managing its internet box, or sometimes in its customer area. But, afterwards, the protocol is not the same depending on whether you subscribe Orange, SFR, Bouygues or Free.
How to improve your Wi-Fi connection ?
Connecting to the Internet in Wi-Fi is very practical. But, a Wi-Fi connection is always slower than a wired connection. However, there are Some very simple gestures to optimize or improve its Internet connection in Wi-Fi.
Here are six tips to boost your Wi-Fi at home: place your Internet box well, secure your network-Wi-Fi, change frequency or Wi-Fi channel, and if that is not enough, equip A Wi-Fi repeater or change subscription to have an internet box compatible with a more recent Wi-Fi standard.
