What is the key technical difference between Wi-Fi and Li-Fi?
What is the key technical difference between Wi-Fi and Li-Fi?
- Wi-Fi uses infrared spectrum to transmit data, whereas Li-Fi uses ultraviolet spectrum to induce an electric tension in an antenna to transmit data.
- Wi-Fi uses light intensity to transmit data, whereas Li-Fi uses radio frequency to induce an electric tension in an antenna to transmit data.
- Wi-Fi uses visible light to transmit data, whereas Li-Fi uses LED lamps to induce an electric tension in an antenna to transmit data.
