Abstract

The invention discloses a WiFi access system based on visible light transmission. The WiFi access system based on visible light transmission comprises a light-Ethernet adapter and a light-WiFi router, wherein the light-Ethernet adapter comprises an Ethernet access controller and a first visible light transceiver module, wherein the Ethernet access controller is connected to the Internet and is also connected to the first visible light transceiver module through twisted pair cables; the light-WiFi router comprises a WiFi access controller and a second visible light transceiver module, wherein the second visible light transceiver module is connected with the WiFi access controller through twisted pair cables; the first visible light transceiver module and the second visible light transceiver module are connected through visible light transmission.

Description

technical field [0001] The invention relates to a WiFi access system based on visible light communication and a data frame conversion method in the system, belonging to the field of local area network communication in communication technology. Background technique [0002] As we all know, visible light wireless communication has the advantages of rich spectrum resources, good confidentiality, green safety, and no license required. However, in order to realize "LiFi" (Light Fidelity) in the true sense, each user terminal device is required to be equipped with a visible light wireless transceiver device, such as LED lights, light signal detectors, etc., and there is still a long way to go before this realization. a period of time. [0003] Currently, when configuring a WiFi router, it needs to be connected to a fixed Ethernet port through a wired method, and its mobility is low, which affects the flexibility of configuring the WiFi router.
