Introduction to Wi-Fi Limitations
Wi-Fi, which operates on the 2.4 GHz and 5 GHz frequency bands, has been the cornerstone of wireless connectivity since its inception. However, it has several limitations that hinder its performance, including interference from other devices, limited range and coverage, and vulnerability to cyber threats. As the number of devices connected to the internet continues to grow, Wi-Fi networks are becoming increasingly congested, leading to slower speeds and reduced reliability. To address these limitations, new technologies have been developed to provide faster, more secure, and more reliable wireless connections.
Li-Fi: A Promising Alternative to Wi-Fi
One of the most promising alternatives to Wi-Fi is Li-Fi, a technology that uses light to transmit data instead of radio waves. Li-Fi operates on the visible, ultraviolet, and infrared spectrum, providing a much broader bandwidth than Wi-Fi. This technology has several advantages over Wi-Fi, including faster speeds, greater security, and reduced interference.
