The invention relates to Light Fidelity (Li-Fi) Hotspot which refers to techniques whereby the internet is provided in the form of a signal embedded in visible light (including for example LED streetlight) emitted by a light source. It will be comprised of a lamp driver (which contains a modulation and demodulation device) and a Li-Fi dongle (which contains photodetector and amplification and processing). The lamp driver accesses a signal by means of a network cable and transmits the accessed signal after modulation to the streetlight. The Li-Fi dongle will convert the received visible light signal into a radio frequency signal and then transmit the radio frequency signal to the modulation and demodulation device to demodulate the radio frequency signal to an original signal, thereby carrying Li-Fi communication using streetlights.
