v. t. e. Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in ...
Li-Fi is a derivative of optical wireless communications (OWC) technology, which uses light from light-emitting diodes (LEDs) as a medium to deliver network, mobile, high-speed communication in a similar manner to Wi-Fi. [4] The Li-Fi market was projected to have a compound annual growth rate of 82% from 2013 to 2018 and to be worth over $6 ...
History of radio. The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy".
Wireless icon. A wireless network is a computer network that uses wireless data connections between network nodes. [1] Wireless networking allows homes, telecommunications networks and business installations to avoid the costly process of introducing cables into a building, or as a connection between various equipment locations.

Wi-Fi Protected Setup (WPS) is a network security standard to simply create a secure wireless home network, created and introduced by Wi-Fi Alliance in 2006. Miracast. Miracast, introduced in 2012, is a standard for wireless display connections from devices such as laptops, tablets, or smartphones. Its goal is to replace cables connecting from ...
Li-Fi (light fidelity) – Wireless communication technology similar to the Wi-Fi standard, but using visible-light communication for increased bandwidth. Near-field communication (NFC) – Communication protocols enabling two electronic devices to communicate within a 4 cm range.
The first wireless products were brought to the market under the name WaveLAN with raw data rates of 1 Mbit/s and 2 Mbit/s. Vic Hayes , who held the chair of IEEE 802.11 for 10 years, and has been called the "father of Wi-Fi", was involved in designing the initial 802.11b and 802.11a standards within the IEEE . [14]
WiMAX. WiMAX (Worldwide Interoperability for Microwave Access) WiMAX base station equipment with a sector antenna and wireless modem on top. Worldwide Interoperability for Microwave Access ( WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media ...
