The range of Li-Fi is fixed approx 10 meter till now but the main research or main development is required to done in increases its length from 10 meter to more range. This range is enough for a particular class room or any other particular room. This paper mainly focus on Li-Fi range and by applying several methodology and experiments we gamut the Li-Fi its range . One method in this paper put forward is use of concave mirror which increase the range of Li-Fi and through which use Li-Fi can be used in big rooms. Most important factor and most important advantage about Li-Fi it is based on visible light communication as this range of wavelength is free available so we don't require any kind of license to purchase this or to use this. If this technology cone into entity than the data exchange become very whirlwind.
