Li-fi sets record data transmission of 10Gbps

Sisoft, which is a Mexican software development company, has been successful in transmitting video, audio and Internet at a data transfer rate of 10Gbps across the spectrum of light emitted by LED lamps.

Sisoft made this possible using a technology called Visible Light Communication (VLC). This technology has the power to illuminate a large work space, such as an office, while at the same time providing full mobile internet to each and every device that comes within the range of light spectrum.

Earlier in April this year, some Scottish researchers were successful in achieving 1.1 gigabytes per second using the same VLC technology.

The technology is also known as light fidelity or Li-Fi and it is being promoted as an alternative to Wi-Fi as it has the potential to maximise the originally provided internet speed to offer safer data transfer and a data transfer rate of up to 10Gbps. The Li-Fi devices transfer data using the LEDs that emit an intermittent flicker at a speed that is not visible to the human eye.

According to Arturo Campos Fentanes, who is the CEO of Sisoft, while Wi-Fi makes use of cables to spread our connections, wireless transmission Li-Fi uses LED lamps that emit high brightness light. According to him, another advantage which Li-Fi has over Wi-Fi is that there is no way to hack the signal since the Internet is being transmitted by light waves and there is no way to steal it.

Li-Fi can also be used in hospitals areas that make use of radiation apparatus and generally distort or block internet signal.

In Mexico, the current highest transfer rate is 200 megabytes per second. Just to get an idea, with Li-Fi a user can download an entire High definition movie in just 45 seconds.

Initially, Li-Fi began with an internet speed of just 2Gbps, but Sisoft worked hard with the researchers from Autonomous Technological Institute of Mexico and adapted the system to be multiplied 5 times.

The first experiments were done with audio, in which a cable was connected via 3.5 mm audio jack from a Smartphone to a protoboard table in order to transform the auditory signals into optical waves. This way a special emitter transmits data across the spectrum of light generated by an LED lamp, which is finally captured by a receptor located in a speaker that reproduces sound.

The mechanics used for wireless internet transmission is also similar. In it, the Sisoft developed station stands above the router device that distributes the internet signal. A lamp LED is then incorporated so as to maximise the speed of data transfer. Light will emulate an antenna, but only the electronic apparatuses that are inside the range of the halo of light and have a receptor for the optical audio signal will have a connection.
