This article aims to bring a metric of capacities and applicability of Light Fidelity (Li-Fi) as a communication system through a direct comparison to subareas of Wireless Fidelity (Wi-Fi) communication, which is the main wireless communication system. The actual vision of Li-fi in a global scenario was discussed based on the use cases of this technology and your relation to 5th Generation (5G) technology. Finally, the difficulties and new paths that this system must still take were presented.
