WiFi, short for Wireless Fidelity, is a ubiquitous technology that enables devices to connect to the internet or other networks wirelessly. It utilizes radio waves, operating on frequencies like 2.4 GHz and 5 GHz, to transmit data between devices and a router. The router, in turn, is typically connected to the internet via a wired connection.
The journey of Wi-Fi began with the IEEE 802.11 standard in 1997, but the term “Wi-Fi” was coined later in 2000 by the Wi-Fi Alliance. Over the years, it has evolved through several generations, each offering increased speed, reliability, and security, with the latest being Wi-Fi 7.
Wi-Fi offers numerous benefits, including enhanced mobility, convenience, and cost savings by eliminating the need for extensive cabling. It supports operational efficiency by enabling seamless data communication and improves accessibility in various public spaces through hotspots.
