Today, Wi-Fi has become an intricate part of everyone’s life. Wi-Fi is present at the home, at the office, and even at the local restaurant or café. Smartphones, tablets, laptops and computers all connect to the Wi-Fi. Everyone is so used to using Wi-Fi that many don’t stop to think what Wi-Fi actually is.
Wi-Fi, also written as Wifi or WiFi, is a wireless networking technology that allows a device to connect to the internet. In order to do this, it uses radio waves. These waves provide network connections that allow data transfer.
Wi-Fi is a trademark that incorporates any “wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers’ (IEEE) 802.11 standards.” Wi-Fi is developed and maintained by the Wi-Fi Alliance, which also owns the trademark.
There are many Wi-Fi standards, including 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac. All of these are based on the original 802.11 standard.
The name Wi-Fi is a play on “Hi-Fi,” which is short for “High Fidelity.” However, it does not actually mean anything.
