Wi-Fi is commonly used for internet access, but as the number of users grows, especially with the rise of the Internet of Things (IoT), this technology faces challenges. A potential solution is emerging in the form of Li-Fi technology, designed to handle increasing demands.
Li-Fi technology utilizes energy-efficient LED lights, similar to those found in homes and offices. Equipped with a light modulation chip, Li-Fi lights transmit data to be received by light receptors, forming a wireless network. Invisible light pulses are emitted to transmit data swiftly, with transmission speeds exceeding 100 Gbps, far surpassing Wi-Fi.
This light-based technology offers a larger bandwidth than traditional radio frequency spectrum, addressing spectrum and frequency crises. Ideal for environments with interference concerns, such as hospitals and aircraft, Li-Fi is especially useful where radio frequency is unavailable, like underground mines.
Li-Fi’s optical waves don’t pass through walls, ensuring data security. Energy-efficient LED lights make Li-Fi a cost-effective option, potentially eliminating the need for devices like routers, modems, and antennas. Li-Fi can work alongside Wi-Fi, providing users flexibility in choosing their preferred network.
However, Li-Fi technology has limitations, including a shorter range of up to 10 meters compared to Wi-Fi’s 32 meters outdoors. Its efficiency is restricted to indoor use, where LED lights can be strategically installed. Additionally, limited device compatibility poses a challenge, rendering the impressive speed offered by Li-Fi meaningless in the absence of widespread device support.
