People often get frustrated when the internet speed becomes dead slow. When more than one person make access on an internet, the traffic becomes high and the speed gradually decreases, to overcome such difficulty a German physicist Herald Hass has come up with a solution called Data through illumination. 10 megabits per sec data rates will be produced by D-LIGHT which is comparatively faster than the average broadband connection. Hence a future can be envisioned having light as transmitting medium to our laptops, smartphones, and tablets. And security would be a snap- if you away from the light source you cannot access the data.
