What is the full form of WIFI and uses it in this time?

Full form of WIFI is defined as the abbreviation of Wireless Fidelity, which means that you can use radio waves to access or connect to the network without wires. An example of Wi-Fi is that you can go to Starbucks and connect to their network to connect to the Internet without having to plug your computer into a cable.

WiFi, is a local wireless technology. Allow electronic devices to transmit data or connect to the Internet through the ISM radio frequency band. It is the basic technology of wireless local area network (WLAN). WiFi enables computers and other devices to communicate wirelessly.

The components of the Wi-Fi network are based on one of the 802.11 standards developed by IEEE and adopted by the WiFi Alliance. Provides a standard method of connecting to a wireless network. WiFi is a trademark of the Wi-Fi Association and is used as a trademark. Applicable to products that use the IEEE 802.11 standard.

WiFi can be used for different types of devices, such as PCs, game consoles, smart phones, digital cameras, tablets, etc. You can use WiFi to create an access point within a range of 20 meters (66 feet). Not as secure as a wired connection, because the attacker does not need a physical connection to use Wi-Fi.


In 1997, Australian radio astronomer Dr. John O Sullivan and engineers Terence Percival and Graham Daniel

WIFI successfully connected to the Internet.

then, the 802.11 wireless local area network (WLAN) protocol was formed and IEEE 802 was built.

Uses of wifi

At present, we have almost no electronic devices that are not connected to Wi-Fi, whether it is our mobile phones, laptops, computers, smart TVs, air conditioners, refrigerators, home security equipment, whether it is your smart watch, system music, lighting, or even our The car is connected. Today, Wi-Fi provides us with many modern conveniences.

Currently, when an electronic device is not connected to Wi-Fi, it is considered obsolete and useless.

Area Coverage of WIFI:

As you know, Wi-Fi is a local area network connection, so its coverage is limited to a limited area.

WLAN has a range of 120 meters indoors and 300 meters outdoors.

WLAN range also depends on the type and capacity of the router.

Technical Specification of WIFI:

Wi-Fi is based on IEEE 802.11 specifications. This is a list of Wi-Fi standards in chronological order.

  • 802.11a
