Can we transmit data from light instead of radiosignal by led and solar panel
Asked by dhimantsinhsolanki4683.7sdatl | 30 May, 2020, 11:40: AM
answered-by-expert Expert Answer
Yes, it is possible to transmit data using light by led and its integration with solar panel. This technology is called Li -fi (light fidelity). It is wireless communication technology. The main difference between Wi-fi and Li-fi is Wi-fi uses radio frequency to transmit data while Li-fi uses modulation of light intensity to transmit data.
