Most of us have been through it; Whether using wireless internet in a cafe, working from home, or competing for bandwidth at a conference, you’ve probably gotten frustrated at the slow (or non-existing) internet speeds.
However, LED light bulbs capable of emitting Wi-Fi signals on their own might be game- changer.
Researchers at Fudan University in Shanghai just demonstrated a new technology that transmits data as light instead of radio waves, and could be ten times faster than traditional Wi-Fi.
The new technology, called Li-Fi, involves LED lightbulbs that emit Wi-Fi signals to nearby computers.
Li-Fi seems like a fantastic invention, as more and more people and their many devices, clog airwaves. Also imagine the design opportunities and different colors?
It's not likely that Li-Fi will replace Wi-fi but it is likely to supplement networks in congested urban areas, or in areas where it isn't safe, i.e. aircraft, hospitals, or in areas where it can't reach, like deep in the ocean.
