Lighting LiFi communication system based on side light-emitting optical fiber

Abstract

The invention provides an illumination LiFi communication system based on a side light-emitting optical fiber, and belongs to the field of illumination communication. The system comprises a T-shaped coupler, a side surface light-emitting optical fiber, a first LiFi optical signal receiving and transmitting module, a second LiFi optical signal receiving and transmitting module, a LiFi uplink optical signal receiving module, an intelligent terminal and an intelligent terminal LiFi optical signal receiving and transmitting module. The lighting communication system solves the problems that the LiFi signal transmission distance is short and visible light cannot penetrate through a wall body, has the characteristics of wide lighting range, high communication speed, strong anti-interference capability, low cost, high safety, simplicity and convenience in installation and the like, and has a good application prospect in the field of lighting communication.

Description

technical field [0001] The invention belongs to the field of lighting communication devices, and in particular relates to a lighting LiFi communication system based on side-emitting optical fibers. Background technique [0002] With the advent of the era of big data and artificial intelligence, the rapid development of the mobile Internet and the rise and popularity of the Internet of Things, tens of trillions of mobile terminals will be connected to the network in the near future, and the demand for wireless communication will increase exponentially. According to Cisco's latest global mobile traffic forecast white paper, global data traffic increased by 71% in 2018, with an average growth rate of 11.5 exabytes per month. At the same time, it also predicts that from 2018 to 2022, mobile data traffic will increase sevenfold, and by 2022 there will be nearly 5.49 million WiFi hotspots around the world, more than 440 times the current number. [0003] However, RF spectrum reso...

AI Technical Summary

Problems solved by technology

Although this technical solution solves the problem that the indoor transmission of LiFi optical signals is isolated by walls or other objects, it has high cost, a large number of equipment, and complicated installation, which does not substantially solve the problem.

[0006] To sum up, the problem with traditional LiFi communication is that although LiFi does have the advantage of being free from radio signal interference and high speed, many of its advantages are overshadowed by the fact that visible light cannot penetrate walls, a key Facts give WiFi a big advantage

This visibility limitation improves system security, but it also greatly reduces the transmission distance of signals and increases the cost of networking
