#8 Wi-Fi

Wi-Fi is one of the most important enterprise innovations of the past 20 years. It allows an electronic device to exchange data wirelessly over a computer network, including high-speed Internet connections. Mobile users can now work remotely from anywhere, use Internet telephones, tap into wireless printers and, with 802.11ac standard, exchange files over a network at Gigabit speeds.

A device that can use Wi-Fi like PC, video-game console, Smartphone, or digital audio player can connect to internet via a wireless network access point called as hotspot. The range of Wi-Fi is about 20 meters indoors and a greater range outdoors.

The Wi-Fi Alliance is a nonprofit international association that promotes Wireless LAN technology and certifies products, defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards". The term "Wi-Fi" is used in general as a synonym for "WLAN" and is a play on words with Hi-Fi (high fidelity).
