Abstract

The invention relates to a superspeed data transmission mobile terminal based on LiFi. The mobile terminal comprises an LED flash lamp capable of sending LiFi light data signals, and may also comprise a camera for receiving LiFi light data signals. The superspeed data transmission mobile terminal has a superspeed for transmitting data signals and is safe and reliable in data transmission.

Description

technical field [0001] The invention relates to a LiFi-based ultra-high-speed data transmission mobile terminal. Background technique [0002] With the continuous development of mobile terminal technology, users have higher and higher requirements for data transmission speed and security of mobile terminals. [0003] At present, most mobile terminals use Bluetooth modules for near-field communication, but its data rate is only 1Mbps; even the popular NFC communication, its data rate is even lower than Bluetooth, and its effective distance is only 10 cm. In addition, these two data transmission methods have poor security performance and cannot be guaranteed during data transmission. [0004] LiFi is called visible light communication in Chinese, which is a kind of data transmission that uses LED light source to turn on and off quickly. Also, the spectrum is 10,000 times larger than the radio spectrum, meaning greater bandwidth and higher speeds. Now that LiFi data transfer...
