Wi-Fi (Wireless Fidelity) is a communication technology used for wireless local area networks (WLAN). Based on the IEEE 802.11 standard, Wi-Fi enables devices to connect to the internet or local networks via radio waves. First defined in 1997, this technology has evolved over time to become an integral part of daily life.HistoryThe origins of Wi-Fi technology trace back to WaveLAN, a wireless communication system developed by NCR Corporation in 1990. This system later formed the foundation of th

Modern wireless communication solutions are increasingly seeking faster, more secure, and environmentally friendly alternatives. As a result of this search, the Li-Fi (Light Fidelity) technology has been developed—a high-speed wireless communication system that transmits data using the visible light spectrum. Compared to Wi-Fi, it offers advantages such as higher bandwidth, reduced interference, and confinement within physical boundaries.This structure demonstrates a Li-Fi system that uses visib
