THROUGHPUT INCREASE IN THE OFFICE LI-FI SYSTEM

Background. Wi-Fi has many disadvantages, such as how the maximum bandwidth is limited by frequency of range. The work uses Li-Fi technology, which visible light for data transmission. range 1000 times greater than entire radio Feedback used to increase throughput. But feedback decreases downstream signal.
 Objective. purpose paper analyse what parameters are advisable change throughput system.
 Methods. Study simulated dependence optimal interval using feedback, and this plot on in system with a mobile user.
 Results. With an area photodiode its refractive index, increases. As receiver speed increases, slightly <0.1%. Reducing angle field view half-angle radiation significantly increases (by 50%) only when decreasing small angles (<10 °).
 Conclusions. It make from material high big area. Since devices often office network, it not reduce receiver's viewing angle, well radiation. may also be beneficial give users more download upload
