Networking system for visible light communication and networking method thereof

Abstract

The invention relates to the field of communication, and discloses a networking system for visible light communication and a networking method thereof. The networking system disclosed by the invention comprises a central office terminal system, at least two visible light network units and a transmission unit; each visible light network unit comprises a visible light transmitting and receiving module and a user side; the visible light transmitting and receiving module and the user side are communicated through visible light; and the central office terminal system is connected with the visible light transmitting and receiving module in each visible light network unit through the transmission unit, such that a star topology network structure is formed, wherein the transmission medium of the transmission unit is an optical fibre. The plurality of visible light network units are connected with the central office terminal system by utilizing the transmission unit, such that the star topology network structure is formed; and thus, the access rates of various visible light network units are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a visible light communication networking system and a networking method thereof. Background technique [0002] With the popularization and development of wireless networks, the number of wireless network users has also increased rapidly. In order to meet the development needs of large-capacity wireless communications in the future, exploring and applying new spectrum and even spectrum resources to realize ubiquitous broadband wireless communications has become a worldwide research topic. Hot and competitive focus. Visible Light Communication (VLC) technology is a broadband wireless access technology. It transmits information through high-speed light and dark signals emitted by light-emitting diodes that cannot be detected by the naked eye, but can be captured and detected by photodetectors and other devices. It can transmit data while providing lighting, and can provide large-c...
