Light Fidelity (Li-Fi) is a bidirectional, high-speed and fully networked wireless communication technology similar to Wi-Fi.
The term Wi-Fi was coined in 1999, with the Wi apparently standing for wireless. It is suggested that the Fi is a play on the term Hi-Fi, or high fidelity, but the Fi in Wi-Fi does not stand for fidelity and was simply the name chosen by the Wi-Fi Alliance. The Wi-Fi Alliance is a global non-profit association of companies that control Wi-Fi products and services.
