During the last decade, the exponential growth of mobile devices and wireless services created an enormous demand for radio frequency-based technologies. Meanwhile, the industry has been revolutionized thanks to the popularization of LED light bulbs, which are more economical and efficient. In that context, light communication (VLC) may be a disruptive technology supported LEDs that gives a free spectrum and high rate, which may potentially function as a complementary technology to the current radio frequency standards. In the current scenario, there’s such a lot of an increased usage of frequency (RF) for mobile communications. This paper reviews about the visible light communications (VLC) technology, which tries to replace a small part of implementation of RF in communication usage.
