The importance of the internet, as numerous applications in domestic settings and businesses rely on it to function, is undeniable. Today, Wi-Fi, which stands for wireless fidelity has greatly improved connectivity since its introduction. Wi-Fi has become the go-to wireless technology. However, the dependency on Wi-Fi has increased over the years, leading to an abundance of load on the radio spectrum thus, affecting its performance. Significantly, Li-Fi had emerges as an alternatives. What are the differences between Wi-Fi and Li-Fi?
While both Wi-Fi and Li-Fi are important technologies for establishing wireless network connections, providing internet access, and transmitting data, they have several key differences.
The key difference between Wi-Fi and Li-Fi lies in the electromagnetic spectrum they use to transfer data. Wi-Fi operates using radio waves, while Li-Fi utilizes visible light as a medium. These different spectrums significantly differentiate Wi-Fi and Li-Fi from each other. In simple terms, Wi-Fi operates within a narrower range of frequencies (3 Hz to 3,000 GHz) compared to Li-Fi (430,000 to 770,000 GHz), resulting in lower capacity than that of Li-Fi.
Other important differences between Wi-Fi and Li-Fi include security and obstacle interference. Li-Fi is generally considered more secure than Wi-Fi in terms of data transmission, as visible light is unable to pass through opaque objects, making it harder to intercept. However, Li-Fi is susceptible to easy disconnection when its receiver is obstructed and unable to receive light, as it requires an unobstructed path from the transmitter to the receiver. On the other hand, Wi-Fi’s radio waves can penetrate walls, allowing for a more stable wireless connection. However, this also makes Wi-Fi more prone to interception and potential data breaches.
All in all, Wi-Fi and Li-Fi are both essential as the future will see more demands on high-speed internet. While the utilization of Li-Fi is new compared to the use of Wi-Fi, it has potential in certain area and field as it offers better security and efficiency. Nevertheless, as Wi-Fi becoming burden with the increasing traffics and demands, the need for Li-Fi as future implementation is undeniable. Furthermore, since Li-Fi is as well come with limitations compared to Wi-Fi, more research and improvement are needed to enable its full potentials.
