WiFi

Wi-Fi is a group of wireless network protocols that are based on the IEEE 802.11 family of standards. These protocols are frequently used for Internet access and local area networking of devices, enabling close-by digital devices to exchange data via radio waves.

What is WiFi?

WiFi is a widely used wireless networking technology that transmits data using radio frequencies. Without using cables, WiFi enables high-speed Internet connections

WiFi allows you to be free of cables. It enables you to access the Internet from almost any location, including a coffee shop, a hotel room, or a meeting space at work. Additionally, it is nearly ten times faster than a standard dial-up connection. With a data rate of 11 Mbps (802.11b) or 54 Mbps (802.11a), WiFi networks operate in unlicensed 2.4 radio channels.

Full Form of WiFi

WiFi, which stands for “wireless fidelity,” is a shorthand for wireless networking technology. The WiFi Alliance asserts ownership of the usage of its certification mark for 802.11x-certified equipment.

How does WiFi work?

There is no actual connected connection between the sender and receiver in Wi-Fi networks. Instead, they operate utilizing radio frequency (RF) technology, which uses a frequency in the electromagnetic spectrum linked to the propagation of radio waves. An electromagnetic field that can travel beyond space is produced when an RF current is applied to an antenna.

An access point is the basis of any wireless network (AP). An access point’s main responsibility is to transmit a wireless signal that computers may identify and utilize to join the network. Computers and other devices need wireless network adapters in order to join a wireless network and connect to an access point.

FAQ - Frequently Asked Questions

Ans. Wi-Fi is a wireless networking technology that enables printers and video cameras to connect to the Internet as well as computers (laptops and desktops), mobile devices (smartphones, wearables, etc.), and other devices.

Ans. WiFi is a wireless network that distributes the Internet via hotspots and links nearby devices to one another. On the other side, the Internet is a vast network of networks where computers can connect and interact using the Internet Protocol.

Ans. In 1997, a group called 802.11 was formed, and the same year WiFi was developed and first made available to consumers. This resulted in the development of IEEE 802.11, a collection of specifications that describe communication for wireless local area networks (WLANs).

Ans. The Austrian-American actress and inventor Hedy Lamarr invented the technology that would later serve as the foundation for the WiFi, GPS, and Bluetooth communication systems used today.
