Revolutionary idea: Using LED lights to transmit data (PART1)

LED lights having the ability to transmit data will bring the human civilisation in to a new era of development.

'Visible light communication' is the simplified way of describing the process where light can be use as a data transmitter. The groundwork for which was probably laid down around 1880s, where Mr Alexander Graham Bell invented a photophone. That being a device that transmitted speech on modulated sunlight.

Gradually, many significant research and development has been made in this area. With LEDs, the data transmission rate had been significantly increased to the point that streaming of youtube video is possible. The switching on and off by the LEDs, so fast that human eye can't detect, enables the transmission of hugh amount of data.

Using light to transmit data will replace the typical radio frequency methods.

I'll bring to you more updates in this area shortly.
