Wireless network

A communications network whose devices exchange data through radio waves or other wireless signals instead of wired connections.

Radio propagation: The behavior of radio waves as they travel through space and interact with materials. Signal strength and coverage depend on how radio waves travel through buildings, terrain, and air.
IEEE 802.11: The family of standards that defines Wi-Fi local-area networking. It specifies the radio and link-layer rules used by most local wireless networks.
Wireless local area network: A local network that connects devices over wireless links, commonly using Wi-Fi. WLANs connect devices within homes, offices, campuses, and public venues.
Ethernet: A family of standards for wired data communication on local area networks. Ethernet replaces radio links with cables, often providing predictable performance and physical access control.
Wi-Fi security: The protocols and practices used to protect Wi-Fi networks and their traffic. Radio transmissions can be received beyond a room’s walls, making authentication and encryption essential.
Orthogonal frequency-division multiplexing: A modulation method that sends data simultaneously over many closely spaced, mutually orthogonal subcarriers. Wi-Fi and cellular systems use OFDM to transmit data efficiently across radio channels.
Wi-Fi: A family of wireless networking technologies based on IEEE 802.11 standards. Wi-Fi is the most familiar form of wireless local-area networking.
Mobile broadband: Internet access delivered to mobile devices over cellular radio networks. It extends wireless networking beyond the range of a local access point.
Fiber-optic communication: The transmission of information as light pulses through optical fibers. Fiber offers high-capacity wired links without the radio interference and shared-air constraints of wireless.
WPA3: The Wi-Fi security protocol introduced by the Wi-Fi Alliance in 2018. WPA3 is a modern security standard designed to strengthen authentication and encryption on Wi-Fi networks.
