In the work, proposals have been developed for building a stand using GNU Radio for researching data transmission technology using visible light technology. Visible light communication (VLC) can be used to build high-bandwidth, high-speed wireless access networks. The main advantage of visible light communication is that RF signals are not obstructed. This makes it possible to use visible light communication in hospitals, on space stations, and so it makes it possible to communicate underwater. Security, simple implementation procedures and range characteristics, license-free, also increase the use of visible light communication for a variety of applications.The aim of this work is to provide guidance on the design and implementation of a visible light communication test bench using software-defined radio.The article describes the architecture of VLC, presents the possibilities of using Software Defined Radio as a starting point for developing commercial VLC applicationsSDR technology provides a framework that can help drive programs to market, generate interest from industry players, and shorten the time to market for future compliant products. The key issues in the implementation of the VLC system is to ensure the ability to transmit data for an LED luminaire with minimal changes in its lighting characteristics and production costs. Thus, this implementation can be improved by narrowing the gap between the industry and the research community.A prototype for visible light transmission was designed using software-defined radios to communicate between analog devices and the computer on which the signal is processed. Using this concept provides the system with sufficient flexibility and modularity to incorporate new features into a prototype without requiring a long development time.Conducted testing of this platform, during which it was possible to transfer a text file.It is concluded that this implementation of the visible light transmission stand can serve as a starting point for the development of low to medium bit rate commercial VLC applications.
