Understanding WiFi and LiFi

What is WiFi?

WiFi, or Wireless Fidelity, is a technology that uses radio waves to provide wireless high-speed Internet and network connections. A WiFi connection is established using a wireless adapter to create hotspots – areas in the vicinity of a wireless router that are connected to the network and allow users to access Internet services.

WiFi has become ubiquitous in homes, offices, and public spaces, offering the convenience of connecting multiple devices without the need for physical cables. Its ability to cover large areas and support many devices simultaneously makes it an essential part of modern communication infrastructure.

What is LiFi?

LiFi, or Light Fidelity, is a wireless communication technology that uses visible light to transmit data. Unlike WiFi, which relies on radio waves, LiFi uses LED lights to send data through light waves. The concept is similar to Morse code, where the LED lights turn on and off at very high speeds, undetectable to the human eye, to convey information.

LiFi offers several advantages, including higher data transfer speeds and increased security. It can be particularly useful in environments where radio frequencies are restricted or can cause interference, such as hospitals, airplanes, and industrial settings.
