Model And Method Of Li-Fi Network Calculation With Multipath Light Signals

Nowadays Wi-Fi technology is widely deployed in Ukraine and all over the world as well, especially for internal access networks, but its usage has some disadvantages regarding speed, confidentiality and interference between channels. Therefore, it is considered to use the Li-Fi network as a flexible approach that would meet the increasingly important requirements of internal wireless broadband access networks The considered technology is innovative, at the moment it reveals all its potentials in achieving not only high data rates and electromagnetic compatibility, but it also provides high economic performance through by using the already existing lighting infrastructure based on LED lamps.The paper focuses at the principle of construction and functioning of the corporate Li-Fi network, also the model of the interaction of its elements is proposed. The basic parameters of interaction between mobile devices were calculated. An example of calculating the energy loss in the light paths of the Li-Fi network is given. The ratio of direct and diffuse light signal was also estimated.Research results can be used to build a fundamentally new type of data transmission networks in many areas, especially those that are sensitive to radio waves, such as airplanes or surgical rooms. The results can also be implemented in firms to simplify the process of designing an optical network, calculating its parameters and assessing the load on such a network, taking into account the provision of modern services to subscribers.The proposed Li-Fi network is offered for deployment for internal wireless networks: meeting rooms, general offices, shopping centers, airports, railways, hospitals, museums, aircraft cabins, libraries, and so on.
