As many users and their committed devices get to wireless web, clogged airwaves are going to make that increasingly complex to latch in to a reliable signal. In any case, radio waves are only one piece of the range that can convey the information. Imagine a scenario in which we could utilize some other sort of wave to surf the web. One German physicist, DR. Harald Haas, has thought of the arrangement is called "Information Through Illumination" - sending information through a LED light bulb that intensity is faster than the human eye can follow. It’s a similar thought behind infrared remote controls, however considerably more powerful. Haas says his development, which he calls D-Light, can deliver information rates quicker than 10 megabits/sec, which is quicker than your normal broadband association. He pays special mind to a future where information for workstations, cell phones, and tablets is transmitted through the light in a room. Also, security would be snitch-if you can’t see the light, you can’t access the data. This paper summarizes  that  transmission of data with the help of light. Which can be used in almost all fields like hospitals, submarines, military applications, etc.
