Introduction to Wi-FI

Wi-Fi is a revolutionary technology which changed the word.  Wi-Fi is local area wireless technology which allows an electronic device to exchange data wirelessly or connect to the internet using the 2.4 GHz and 5 GHz radio frequency and Wi-Fi name is Trademark.

Why Wi-Fi is So Famous

Nearly all electronic device have Wi-Fi built in it which range from Laptops, smartphones, tablets, cameras, toasters and even some refrigerators, yes that is not a joke indeed, Wi-Fi refrigerator are called Smart refrigerator but why you need a Wi-Fi on a refrigerator because it display weather on your refrigerator display plus you can check all your Facebook feed and browse the web for cooking recipes or even you can leave notes all from the refrigerator display which in on its door.

History for Wi-Fi

The origins,  802.11 Wi-Fi standard date backed in 1985 by the ruling of US Federal Communications Commission which had released The ISM band for unlicensed use, so now properly you will be wondering what the hell is ISM Band.

What is ISM BAND?

ISM stands for “industrial, scientific and medical” which is a radio Bands that basically use internationally,  the radio frequency (RF) for industrial, scientific and medical purposes other than telecommunications, microwave ovens which are operating at 2.45 GHz are included in ISM Band but why;

The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency that’s why ISM Band limited to certain bands of frequencies, in short any communications devices must be able to tolerate any interference generated by ISM device for example a microwave oven in this band range.

Who is the Father of Wi-Fi

There is no solid evidents who really had invented the Wi-Fi but most of

the credit go to Vic Hayes who  was an Dutch Engineer, due to his involvement in  IEEE committee that created the 802.11 standard for Wi-Fi  in 1997, IEEE Stand for Institute of Electrical and Electronics which was found in  1963 Today IEEE it is the world largest association of technical professionals Which covers

Electrical, Electronics

Communications

Computer Engineering

Computer Science

Information Technology

 IEEE has more than 429,000 members around the world.


The First Wi-Fi Product

Under the name of  WaveLAN, The world first ever Wi-Fi Sytem was invented by NCR Corporation with AT&T Corporation  in 1991, it was an Cashier Systems

Wi-Fi Certification and Wi-Fi Alliance

Wi-Fi Alliance was created in 1999 because the main problem was back than the IEEE do not test any Wi-Fi device  for  compliance with their standards to have any Wi-Fi Certification , Today Wi-Fi Alliance enforces the use of the Wi-Fi brand to technologies based on the IEEE 802.11 standards from the IEEE.

To certify your device to have an Wi-Fi logo on it than the device  need the certification which in the process requires conformance to the

IEEE 802.11 radio standards the WPA and WPA2 security standards, and the EAP authentication standard But again Not every Wi-Fi device is submitted for certification because of this Wi-Fi Alliance may allow you to use the names in your device as a Wi-Fi device as long as it is an Wi-Fi compliant.

Yes Thats All about Wi-Fi in Short So Indeed Yes Wi-Fi is an Revolutionary Technology.

Jimmy a Geek

Jimmy a Geek is a Tech Geek Which is Me, I Write and Talks About Whats Going on Currently in Technology Field and How to Be Successful in IT. I Was Born as a Geek. For Years I m Doing Computer’s But Now I m an Web Engineer and eCommerce Developer. I Started in IT Which I Called it Computer’s Back Than in 1999. My Father Give Me a Pentium II PC Which Get Me Started in Computers But Latter I Went into Development Started with Java BuT End Up in PHP, From There I Started the True Web Engineering.
