Abstract:
Data transmission plays important part in our daily life. Without passing data in a day is quit
impossible in this development world where data plays very critical role. Li-Fi ushers new
being of data transfer via wireless technology. Li-Fi is stands for Light Fidelity. Li-Fi simply
put, it uses visible light to exchange data. Light can pass free space and cannot pass rock-solid
prosperities like walls of room, stones etc. From different research, Li-Fi can covering range
of it nearly 10 miters and near so. As it discussed that, covering area of Li-Fi nearly 10 miters
which is not good enough to use in household or office or big halls like auditorium or
conference room. For that reason, need to design new system that help out to solve the problem
and improve the covering area. For set up Li-Fi System, LED are setting up with Li-Fi router.
LED lights reaching place are the covering area. To enhance the range of Li-Fi, need to reach
LED light more area. For that, this research tries to design and develop new system by using
concave mirror and changing positon of LED. In new designed system, mirror try to improve
covering distance that normally at present covered by Li-Fi and better position help to minimize
the use of LED, which is proved both theoretically and mathematically by this research.
