One of the big problem in wireless communication based on radio frequency is bandwidth or radio frequency spectrum ,to overcome this issue we are going to use wireless communication through Light (LED Light etc). In this communication we have many advantages like low power consumption & no any fear to interference between different-different radio frequency signals and PCM framing is used to improve data rate and signal to noise ratio in audio communication through LED light. In PCM firstly data is converted into digital form after that put preamble and post-amble and guard period in burst frame. Li-Fi gives higher information/data measure, high efficiency, good connectivity, much more secure than Wi-Fi and data rate (speed)is also high about to 10 Gbps according to laboratory experiment. According to nature of LEDs has light weight, cheaper in cost and lightning units, there are innumerable chance to take advantage of this method.
