What is required for a standard LED light bulb to transmit Li-Fi signals?

Question

BlackTom AI · Accepted Answer

When evaluating what is required for a standard LED light bulb to transmit Li-Fi signals, we need to consider the core enabling component that handles data modulation.
Option a: 'A cooling fan' — While cooling can be important for some electronics, a cooling fan is not what enables Li-Fi transmission in a standard LED bulb. The presence of a fan does not encode or modulate data onto light; it merely dissipates heat.
Option b: 'A wireless extender' — A wireless extender helps extend network reach for RF signals, but Li-Fi uses light to carry data, not radio waves. A wireless extender is not a necessary component inside the LED bulb to enable Li-Fi transmission.
Option c: 'A microchip' — Correct. A microchip inside the LED bulb handles the data modulation, encoding, and decoding required for Li-Fi communication by controlling the light output at high speeds in response to data streams.
Option d: 'A signal booster' — A signal booster amplifies signals in some contexts, but Li-Fi transmission relies on the modulation capabilities of the microelectronics inside the bulb rather than an external booster to transmit data through light.
In summary, Li-Fi functionality is achieved through the embedded microchip that modulates the LED light to carry data, rather than ancillary cooling, wireless extenders, or boosters.
