Dear user if you are find What is Wifi and hoe its work.and how its work know you are on a write place.

write palce wo well give you information about every thing what is a wifi and how he was work and how its divination A to Z every Thing….

What is A wifi ?

i-Fi (/ waɪfaɪ /) [1] is a family of wireless network protocols base on the IEEE 802.11 family standard, commonly use in devices and Internet access networks local networks, enabling something close to digital devices.

To. There is only one data exchange using radio waves. It is one of the most widely use computer networks in the world for connecting desktops and laptops, tablets, smartphones, smart TVs, printers and smart speakers, both at home and in small office networks.

Wireless routers are use all over the world to connect to them. Provides internet access to the internet and people in public places such as coffee shops, hotels, libraries and places with access to the airport.

Wi-Fi is a trademark of the non-profit Wi-Fi Alliance, limiting the use of the term Wi-Fi Certifie to products that have successfully complet the interference certification test.

[2] [3] [4] In 2017 Wi-Fi, the Wi-Fi Alliance include more than 800 companies worldwide. [5] to 2019 20193.0. As of this year, more than 5.55 billion Wi-Fi enable devices are shipp worldwide each year. []]

Wi-Fi uses various components of the IEEE 802 protocol family and is designe to interfere seamlessly with its Electronic Ethernet Brother.

Compatible devices can network to each other via wireless access points, as well as wire devices and the Internet. Different versions of Wi-Fi have different IEEE 802.11 protocol standards, and wireless technology sets the radio bandwidth to determine the maximum achievable limits and speeds.

Wi-Fi often uses the UHF 2.4 GHz (120 mm) and SHF 5 GHz (60 mm) radio bands. These bands are distribute across multiple channels. Channels can be share across the network, but only one transmitter can broadcast locally on a channel at any given time.

The Wi-Fi wave band has a relatively high absorption rate and is ideal for visual clues. Many common obstacles such as walls, pillars and tools. These can lower the threshold at a wider level, but they also help reduce interference between different networks in a congeste environment.

Access points (or hotspots) are often about 20 meters (66 feet) in size in a house, but some modern locks require areas up to 150 meters (490 feet). To do. Access point coverage can be as small as a room with walls that block radio waves, or it can be wide square kilometers (miles) so that you can roam between them using multiple temporary access points.

I can do it. Over time, Wi-Fi ruting and visual efficiency have improve. By 2019, in the near future, some versions of Wi-Fi running on the right hardware will reach ruting of up to 1 Gigabit / s (Gigabit / s).

History Of wifi ?

Main article: IEEE 802.11; Story
In 1971, ALOHAnet connecte the Greater Hwan Islands to the Bay Area UHF packet network. The ALOHAnet and ALOHA protocols prece Ethernet and later the IEEE 802.11 protocols.

1985 Decision of the Federal Communications Commission of the USA to allow the use of the band without permission. []] These are frequency links similar to those use in appliances such as microwave ovens and are subject to interference.

The technical birthplace of Wi-Fi is the Netherlands. [8] In 1991, AT&T Corporation coine the pre-802.11 race name WaveLAN for use in the NCR Corporation cash systems.

[9] Since then, both have been inducte into the Wi-Fi NOW Hall of Fame. [ten]

It was update in 1999 with 802.11b and became popular with link speeds of up to 11 Mbit / s.


A great commercial success was made possible in 1999 thanks to the adoption of Wi-Fi by Apple in the iBook series notebooks. It was the first consumer product to offer Wi-Fi network connectivity and was later designate an airport by Apple.

[13] [14]

Wi-Fi uses many patents held by different organizations. [15] In April 2009, 14 technology companies agree to pay CSIRO 1 billion for CSIRO patents.

[16] This has  Australia to label Wi-Fi as an Australian invention, [17] which has been the subject of some controversy. [18] [19]  [16] [20] [21] In 2016 2016, Australia’s contribution to the exhibition

“World History in the World” at the Australian National Museum was selecte as evidence for regional networks. [Twenty two]
