How does LiFi work?

LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several lightbulbs that form a wireless network.

When an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can be changed at extremely high speeds. This means that the signal can be sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data.  Also when the LED is ON, you transmit a digital 1 and when it is OFF you transmit a 0.

The intensity modulation cannot be seen by the human eye, and thus communication is just as seamless as other radio systems, allowing the users to be connected where there is LiFi enabled light. Using this technique, data can be transmitted from a LED light bulb and back at high speeds.
