Submission + - UK Project Achieves 10.5Gbps Speeds via Micron Sized LED Light Bulb Network

Mark.JUK writes: The Ultra-Parallel Visible Light Communications (UP-VLC) project in the United Kingdom has successfully developed Light Fidelity (Li-Fi) technology, which uses tiny LED (Light-Emitting Diode) light bulbs to transmit data via the visible light part of the electromagnetic spectrum, so that a single bulb can deliver speeds of 10.5Gbps (Gigabits per second).

The technology works by causing the LED to flash incredibly fast. At the same time Orthogonal Frequency Divisional Multiplexing (OFDM) is used to further improve performance by varying the lights intensity and turning each of its three primary colours (red, green and blue) into data channels (i.e. each colour can send data at speeds of 3.5Gbps).

The trouble with being punctual is that people think you have nothing more important to do.
