LED light bulbs that connect you to the internet
A number of scientists at the Fraunhofer Institute for Telecommunications in Germany have created a way to connect to the internet through the use of hundreds of thousands of interconnected LED light bulbs.
A mass of brightly colored light bulbs were all hooked together in order to create a 800Mbps-capable network, which has the capability to transfer information through the blinking of the lights. Anyone looking to get online with the help of the bulbs would need a special photo diode attached to their device, which would then be able to pick up on the incredibly fast light signals.
According to Geek.com this innovative design is a form of Visible Light Communication, or VLC, which refers to the use of light to transmit information. It's a fascinating way of communicating which doesn't interfere with other kinds of wireless networks and signals, however it depends on a clear and unobstructed path of light, so if something is blocking it, the information wouldn't be transferred properly. Regardless of its limitations, this recent light bulb experiment could not only change the way we communicate in the future, but it's pretty impressive to look at as well.
