Wireless Fidelity is the full form of WiFi is an alternative to wired technology that is commonly used for connecting devices in wireless mode.
A Wi-Fi network connects computers to each other to the internet and to the wired network. Wi-Fi networks use radio technologies to transmit and receive data at high speed.
The concept of operation of a Wi-Fi network is the same as walkie-talkies. Wi-Fi is a hot spot created by installing an access point to an internet connection. The access point acts as a base station.
When a Wi-Fi enabled device encounters a hot spot, the device can connect to that network wirelessly.
Wi-Fi stands for Wireless fidelity is an alternative to wired technology that is commonly used for connecting devices in wireless mode. There are numerous advantages of Wi-Fi in different areas because of some useful features of Wi-Fi.
Wireless fidelity uses two frequency bands available to use when setting up the Wi-Fi network. as well as some simple rules to help you decide the best bandwidth to use for the wireless networks.

Wi-Fi technology :
Wi-Fi network uses radio technologies to transmit and receive data at high speed. Some set of the standard given below :
- IEEE 802.11b
- IEEE 802.11a
- IEEE 802.11g
1. IEEE 802.11b
- It was formulated in the year 1999
- It operates at 2.4 GHz radio spectrum
- The actual speed is 4-6 Mbps
- It supports a range from 100-500 feet
- It is a very popular Wi-Fi technology and is the least expensive
- It has a theoretical speed of 11 Mbps within 30 m range
2. IEEE 802.11a
- It was introduced in 2001
- It operates at 5GHz with theoretical speed 54 Mbps
- It is the most expensive technology and hence reduce its popularity
- It is actual speed varies from 15-20 Mbps in a range of 50-75 feet
- It is not compatible with IEEE 802.11b
3. IEEE 802.11g
- It was introduced in 2003
- It was an improved version with inherent advantages of 802.11a and 802.11b specification
- It operates at 2.4 GHz radiofrequency
- It has a speed of 54 Mbps and covers a range of 100-150 feet
- It is compatible with IEEE 802.11b
Wi-Fi covers various uses of Wi-Fi applications like home-based LANs full form Local Area Network and public place available hotspots where people can wirelessly share information or connect to the internet device with an equipped laptop with the help of a central antenna.
