According to TechRadar, this device is set to revolutionize the way we think about internet connectivity.

Potential Impact of Li-Fi in Various Applications

Li-Fi is estimated to be highly effective in secure communications due to its inability to penetrate walls, with significant benefits in urban environments and rural connectivity. Estimated data.

Understanding the Technology

At the heart of this innovation is Li-Fi (Light Fidelity), a wireless communication technology that uses light to transmit data. Unlike traditional Wi-Fi, which uses radio waves, Li-Fi leverages the visible, ultraviolet, and infrared light to transfer data at incredible speeds. Optics.org reports that this technology is not only faster but also more secure, as it cannot penetrate walls.

How It Works

Li-Fi technology uses LED lights to transmit data. These lights modulate at extremely high speeds, imperceptible to the human eye, to send information to a receiving device. The receiving device then decodes the light signal back into data. This process enables data transmission at speeds up to 25 Gbps, a significant leap from current Wi-Fi capabilities.
