The number of connected devices is rapidly increasing and the radio spectrum is not enough, but the visible light spectrum is broad enough to accommodate all the devices. Radio waves cause signal distortion which harms the efficiency of the system, but light rays are less prone to signal distortion. The purpose of this research is to establish efficient Li-Fi one-way communication and to derive a mathematical formula for finding exact coordinates of the object by utilizing some 3D geometrical concepts. The proposed model in this paper is responsible for finding the exact coordinates of the object irrespective of the physical architecture of the indoor area. This research uses only 10 bytes of data packet size for accurate positioning in an area that can accommodate more than 1000 transmitters. The accuracy received in indoor positioning using the mathematical formulas prescribed here is up to 6 cm, which is a benchmark in the field of indoor positioning.

连接的设备数量迅速增加，无线电频谱不够，但是可见光谱足够宽，可以容纳所有设备。无线电波会导致信号失真，从而损害系统效率，但是光线不太容易出现信号失真。这项研究的目的是建立有效的Li-Fi单向通信，并通过利用一些3D几何概念来导出用于找到对象的精确坐标的数学公式。本文中提出的模型负责寻找对象的精确坐标，而与室内区域的物理结构无关。这项研究仅使用10个字节的数据包大小来在可容纳1000个以上发射器的区域中进行精确定位。
