LiFi (Light Fidelity) is a high speed wireless communication technology that uses the frequencies of light waves in the infrared, ultrared and visible portion of the electromagnetic spectrum to deliver data. It overcomes several inefficiencies (bandwidth, data rate, data security, etc.) of the current wireless communication technologies, such as WiFi (Wireless Fidelity) and Bluetooth, which operate in the radio frequency (RF) band around 2.4 GHz. In a LiFi network, data transmission is made by modulating light into a carrier signal which consists of light pulses sent out at short intervals. Solid state lighting based on LED technology unlocks the new wave of advancements in LiFi. LEDs are semiconductor devices that are inherently controllable and offer high device stability over long switching cycles. Sophisticated modulation techniques therefore can be implemented in lighting systems for LiFi applications.
