Imagine finding a light bulb which is more efficient, less polluting and comes with a facility of data transmit. If you thought I am talking in my dream, you ought to read on and find out that Researchers at Boston University’s College of Engineering are working on something completely amazing. They are believed to be working on a Wi-Fi replacement technology which they call “Smart Lighting” that sends data not via the radio spectrum, but the visible light spectrum. The agenda is to replace the standard dumb light-bulbs by LED “smart lights,” which work at imperceptibly high rates as a way to transmit data in a network which would turn out to be helpful within an office. This means the moment you tap a light on, you can access data on any device with wireless capability anytime without the use of wires. Researchers believe initial speeds would hit between 1 and 10 megabits per second.

Not only does it eliminate clutter and wiring, its best feature comes in the security it provides. Considering the fact that the basis for this technology is the visible light, the signal won’t pass through walls.
Given its advantages, this could turn out to be a potential threat to the Wi-Fi system!!
