The technology can illuminate a large workspace, such as a desk, while delivering full mobile internet to every device that falls within the range of the light spectrum.
The technology, called Li-Fi or Light Fidelity, is being touted as an alternative to Wi-Fi as it will maximize the original speed of the internet to provide safer data transfer and a transfer rate of up to 10 gigabytes per second.
The Li-Fi device circulates data through LEDs that emit intermittent flicker at a speed imperceptible to the human eye.
“As Wi-Fi uses cables to extend our connections, Li-Fi wireless transmission uses LED lamps that emit high-brightness light,” said Arturo Campos Fentanes, CEO of Sisoft in Mexico.
Another advantage over Wi-Fi is that there is no way to hack the signal since the internet is transmitted through light, there is no way to “steal” it.

Additionally, it can be installed in hospital areas that use radiation devices and typically block or distort the internet signal, Fentanes said.
With this new technology, expansion across the market is sought, with lower costs and an increased service of five thousand percent Internet speed.
Currently in Mexico, the highest transfer rate is 200 megabytes per second. Just to get an idea, with Li-Fi you can quickly download an entire HD movie in just 45 seconds.
Also known as visible light communications (VLC), this technology started out with two gigabits per second internet speed, but Sisoft and researchers at the Autonomous Technological Institute of Mexico (ITAM) have adapted the system so that be multiplied by five.
Fentanes explained that the first experiments were conducted with audio, in which a cable is connected via a 3.5mm audio jack from a smartphone to a protoboard table to transform the auditory signal into optical waves.
In this way, a special transmitter transmits data through the spectrum of light generated by an LED lamp and is captured by a receiver located in a loudspeaker which reproduces the sound.
For wireless Internet transmission, the mechanics are similar. The station developed by Sisoft stands above the router which distributes the Internet signal and an LED lamp is incorporated to maximize data transfer speed.
The light will emulate an antenna, but only the electronic device that has the receiver for the “optical audio” signal and is within range of the halo of light will have a connection.
