Problems solved by technology

Although Lifi communication has the advantages of green, low energy consumption, no electromagnetic radiation, wide bandwidth and spectrum, and high transmission rate, there are still many shortcomings. For example, the network signal will be interrupted when the light is blocked, and the realization of reverse communication is also difficult.

Abstract

The invention discloses a Lifi (light fidelity)-based data transmission device and method, and relates to the technical field of cloud computing. A Lifi visible light communication technology is combined with a Wifi wireless transmission technology to realize high-speed downloading of a large data file by fully utilizing a high-speed Lifi downlink channel; a mobile equipment terminal is connected to a Wifi wireless router through Wifi, a cloud center is requested for data, and then the data is returned by the cloud center, and is transmitted to the mobile equipment terminal in a downlink direction through a Lifi visible light wireless network AP; a one-way transmission channel design is adopted, so that the system complexity is reduced, a system can be realized more easily, efficient data transmission is effectively realized, and the network bandwidth efficiency and user experience are greatly improved.

Description

technical field [0001] The present invention relates to the fields of information visible light communication technology, mobile communication technology and cloud computing technology, specifically a Lifi-based data transmission device and method. Background technique [0002] LiFi (LightFidelity, visible light wireless communication, also known as "light fidelity technology") is a new wireless transmission technology that uses the visible light spectrum (such as the light emitted by a light bulb) for data transmission. It can use visible light to achieve wireless communication, that is, using electrical signals Controlling the high-speed flashing signals invisible to the naked eye from light-emitting diodes (LEDs) to transmit information, its communication speed can reach hundreds of megabits per second, or even several gigabits per second. The future transmission speed is likely to exceed optical fiber communication. [0003] LiFi can use the installed equipment (the ubiq...
