What is WiFi technology?


WiFi, or Wireless Fidelity, is a technology that allows electronic devices to connect to a wireless LAN (WLAN) network. The term WiFi is often used to refer to the 802.11 technology, which is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4, 3.6 and 5 GHz frequency bands.

The Importance of WiFi

WiFi technology has become an integral part of our daily lives. It provides us with wireless access to the internet and other devices within range, making it possible for us to stay connected wherever we are.


How Does WiFi Work?

WiFi works by transmitting data via radio waves. These waves are emitted from a router and can be picked up by any device that has a wireless adapter.

  • Wireless Router: This is the device that sends out the WiFi signal. All your devices connect to the router.
  • Wireless Adapter: This is found in your WiFi-enabled devices. It receives signals from the router and translates them into data that your device can use.
  1. Your device’s wireless adapter translates data into a radio signal and sends it to the wireless router.
  2. The wireless router intercepts the signal and deciphers it. The router then dispatches the information to the internet via a tangible, wired Ethernet connection.
  3. The procedure also operates inversely, with the router acquiring information from the internet, converting it into a radio signal and transmitting it to the computer’s wireless adapter.

Conclusion

In conclusion, WiFi technology has revolutionized the way we access the internet and communicate with each other. It has made our lives more convenient and our connections stronger and more reliable.
