LiFi and WiFi are wireless communication technologies. LiFi uses visible light communication and is a newer technology that can provide data rates over 10Gbps, while WiFi uses radio waves and has been used widely since the 1990s. Both technologies allow wireless internet access and connectivity. However, LiFi has advantages such as higher bandwidth, energy efficiency through use of LEDs, and more secure data transmission compared to WiFi which has limitations such as interference issues, limited range, and data security risks.
