A Mexican software company has managed to transmit audio, video and Internet across the spectrum of light emitted by LED lamps — at a data transfer rate of 10 gigabytes per second.
The technology can illuminate a large work space, such as an office, while providing full mobile Internet to every device that comes into the range of the light spectrum.
The technology, called Li-Fi or light fidelity, is presented as an alternative to Wi-Fi because it will maximise the original provided speed of the internet to offer safer data transfer and a transfer rate of up to 10 gigabytes per second.
The Li-Fi device circulates data via LEDs that emit an intermittent flicker at a speed imperceptible to the human eye.
Another advantage in comparison to Wi-Fi is that there is no way to hack the signal since the internet is transmitted by light, there is no way to “steal it.” — PTI
