Wireless communication (or just wireless, when the context allows) is the transfer of information ( telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
Wireless network. 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.

Antennas. 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 ...
An example of a Wi-Fi network. A wireless LAN ( WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. This gives users the ability to move around within the area and remain ...
This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies. CDMA2000 is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites.
IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p . The standards are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/ MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments.
MIMO technology can be used in non-wireless communications systems. One example is the home networking standard ITU-T G.9963 , which defines a powerline communications system that uses MIMO techniques to transmit multiple signals over multiple AC wires (phase, neutral and ground).
A wireless broadband network is an outdoor fixed and/or mobile wireless network providing point-to-multipoint or point-to-point terrestrial wireless links for broadband services. Wireless networks can feature data rates exceeding 1 Gbit/s. [ 4] Many fixed wireless networks are exclusively half-duplex (HDX), however, some licensed and unlicensed ...
