In today’s video we will discuss all these information in detail.
You might know that the full form of Wi-Fi is Wireless Fidelity, but it’s actually not.
You may be surprised to know that Wi-Fi is not actually an acronym for anything.
When the Wi-Fi system came into being, the wireless industry was looking for a suitable name that was user-friendly and easily recognizable.
Because in the beginning when Wi-Fi did not have a specific name, the technology was known as IEEE 802.11.
Now it is obvious that this long name is difficult to pronounce and could not be used due to not being user friendly.
So the Wi-Fi Alliance of the wireless industry hired different brands to come up with different name ideas to choose a name for the technology.
After the conference of these brands, 10 names came out, one of which was Wi-Fi, which was the closest word to Hi-Fi. Well, for your information, let me tell you that the full form of hi-fi is High Fidelity.
Therefore, Wi-Fi was unanimously adopted as the professional name in this conference.

The history of Wi-Fi begins in 1880 when Henry Rudolf Hertz transmitted electromagnetic waves for the first time. This period is called the early period of radio technology.
After that, the American scientist Nikola Tesla took Hertz’s work further and continued his research on radio waves.
Then in the new century, Marconi introduced wireless technology for commercial use for the first time.
After that, an American actress and scientist, Hedy Lamarr, introduced the technique of frequency hopping, in which the frequency changes repeatedly and the radio transmission continues without interruption.
Meanwhile, the technology of transferring data in the form of radio packets was introduced by AloohaNet at the University of Hawaii in 1971.
He transferred data packets wirelessly without using any satellite wire for the first time in history.
He connected 7 different campuses of the university under the same system which was controlled by a central computer.
After that in different periods. IEEE 802.11 Wi-Fi emerged in its current form in 1999 through various stages.
So far, a total of 7 types of Wi-Fi have been released, from Wi-Fi 1 to Wi-Fi 6, and Wi-Fi Seven 7 is also coming soon.
Let’s look at all these types in turn.
The first original Wi-Fi standard is known as IEEE802.11 in the Wi-Fi Alliance.
The name was given. This was the zero generation of Wi-Fi.

followed by IEEE 802.11.a
Nami Wi-Fi came out in 1999. It is also called Wi-Fi 1. It works on 5 GHz band. And it has a maximum data transfer rate of 54Mbps.

Similarly, Wi-Fi 2, known as IEEE802.11b in the Wi-Fi Alliance, was a second variant of Wi-Fi One that operated at 2.4 GHz. It also came out with Wi-Fi One in 1999 and included The data transfer rate was 11Mbps.

The third generation of Wi-Fi, known as IEEE 802.11g in the Wi-Fi Alliance, was named Wi-Fi 33. It operates at 2.4 GHz and was introduced in 2003. It offers data transfer speeds of up to 54Mbps.

Wi-Fi 4, named IEEE 802.11n by the Wi-Fi Alliance, came out in 2009 and operates on both the 2.4 and 5 GHz bands and offers much higher data speeds of up to 600Mbps.

Wi-Fi 5 5, dubbed 802.11ac by the Wi-Fi Alliance, came out in 2014. It also operates on both the 2.4 and 5 GHz bands and offers much faster data speeds of up to 1.3 gigabits per second. Is .
After that, the last type of Wi-Fi to come out till now is Wi-Fi 6, also known as Wi-Fi 6E.
Named 802.11ax by the Wi-Fi Alliance, it is the latest Wi-Fi to come out in 2019 and it also works on both 2.4 and 5 GHz technology, providing the fastest data transfer rate that is Up to 10 to 12 Gbps and this is very high speed data.

In the coming days, a new type of Wi-Fi is coming soon and work is underway. will be used.
It works on three bands 2.4, 5 and 6 GHz and it will have a very fast data transfer rate which is up to 40Gbps super speed.
in this video we have mentioned the reason for naming Wi-Fi,

And all types of Wi-Fi have been discussed.
