Wifi Presentation

Welcome everyone !If you are here, it is certainly because somehow you got interested about Wifi. In this blog you will clearly understand what Wifi is, how does it work, and the future of wifi's waves. Please, read this blog with the consideration and the attention it deserves.

Wifi's history

Who discovered it ?

Heddy Lamarr, an American actress, is considered to be the one who discovered wifi thanks to her many scientific works that led to the wireless connection.

Wifi's evolution

The first WiFi protocol was released in 1997, and it provided up to 2 Mbit/s link speeds.

Since then, several generations of WiFi have been released, each offering faster speeds than the last.For example, the latest generation, WiFi 6, provides up to 9608 Mbps of link speeds, making it almost 5000 times faster than the first generation.

What wifi may be ?

The term wifi is short for Wireless Fidelity. It literally refers to a wireless internet connection system. The Internet access is available through the transmission of radio waves.

Tha radio waves are waves which have a wavelength between a millimeter and 100 000 km.

How does wifi work ?

When you download a file over a wifi network, something known as a wireless router first receives data from the internet through the high-speed internet connection and converts it into radio waves. The wireless router then transmits the radio waves to the surrounding area and the wireless device that initiated the download request captures these waves and decodes them.

Mobile phone network

Like we said earlier, the wifi only send waves in a small area aroun the router, this is when the mobile phone network gets interresting. It is the exact same idea than wifi but it has got a longest range. The radio technology used aims to share a radio spectrum between multiple users, themselves distributed in different radio cells according to their spatial situation. So, to communicate from a mobile phone, it is necessary to be within range of a relay antenna invested by its mobile operator so as to receive a sufficiently powerful radio signal.

Is 5G the future of connectivity?

While previous generations of cellular technology (such as 4G LTE) were all about providing connectivity, 5G raises the bar by delivering connected experiences from the cloud to customers. 5G networks are virtualized and software-driven, and take advantage of cloud technologies.

Conclusion

To conclude, nowodays we use wifi networks almost everywhere, allowing us to conveniently connect to the internet and mobile devices without cables. That is why we must continue to develop it, the transmission of informations is the key to humanity's survival. This is what our scientist team thinks about the wifi, for us, it is going to enhance humanity again and again.
