LiFi is getting closer and closer.

In 2011 there was talk of a new technology that would replace WiFi, it would be faster, cheaper and more stable, it was engineer Harald Haas during the TED Conference, who spoke of LiFi.

This is a data transmission system using visible light, which through flashing LED lights, imperceptible to the human eye, can achieve a transmission speed of up to 224 Gbps.

The commercial implementation of this technology would impact the market as it could provide users with a much faster and cheaper Internet.

LiFi connectivity uses the full spectrum of light to send the data signal to the receiver, decreasing interference and signal failures that are common in WiFi, resulting from obstacles and remoteness.

The LiFi receiver has the ability to interpret the data with equal fidelity in any spectrum, between infrared and ultraviolet, and not only in two frequencies, which are the 2.4 GHz and 5 GHz bands of its predecessor, WiFi.

Another advantage is security, since whoever wants to use the network must have physical access to the light with the receiving device to be able to communicate, while in WiFi the violator only needs to use the password to access the signal, regardless of the distance.
