On a global scale, we can see that society in general is increasingly connected, whether for the
need for information, leisure, education, or work. Many are the ways to navigate the waves of
cyberspace, the means that allow this connection are widespread, whether through cables or
simply through the air. Wireless communication has been expanding and filling gaps that were
once in evidence, gaps that allow the emergence of new technologies. The theme motivates us
to research ways to test the range and quality of service of the data transfer rate of LI-FI
technology, along this journey it will be possible to better understand the applications of this
technology, which has a range of possibilities.Thus, the Li-Fi networks using simply light
instead of radio frequency signals to make the data transmission, are able to enable the use of
this technology in various environments, so the VLC can be used more safely. Examples are
applications in aircraft, medical devices and hospital units where Wi-Fi is restricted, or even
underwater. The methodology applied in this research was based on a bibliographic review,
carried out through research in scientific articles, electronic databases and specialized
magazines in the area of telecommunications. After the search and selection of articles and
literary documents, there was the tabulation of the information found means of Inclusion and
Exclusion. Within this context, the development of a test system to validate the throughtput
quality of service in LI-FI boards has a lot of relevance and helps in the better understanding
of this phenomenon within a controlled environment (laboratory) that will allow a sunk study
and better observation of the Visible Light Communication (VLC) technology.
