Wi-Fi, short for Wireless Fidelity, represents a set of standards for wireless local area networks (WLANs) and is commonly called wireless Ethernet. This technology enables devices to connect to networks and the Internet without the need for wired connections.
Wireless communication refers to the transfer of electromagnetic signals from one location to another without the use of cables, commonly using infrared light or radio waves. While infrared communication is typically limited to short distances, radio waves can cover much larger areas.
