摘要
可见光通信是一种新型的无线通信技术。传统的无线通信技术例如蓝牙、Wi Fi等采用射频信号传输数据信息,而可见光通信在发射端采用白光发光二极管作为光源,在接收端采用光电传感器作为检测器进行数据传输。本文全面分析了可见光通信的优势,列举了可见光通信技术在国内外的应用研究与发展,并给出了目前可见光通信发展中面临的一些挑战。
Visible light communication is a new technique of wireless communication. Traditionally, data or information is transmitted over the wireless medium using radio frequency signal in conventional wireless communication like Bluetooth and Wi Fi.However, white light emitting diodes used as transmitters and photoelectric sensors used as receivers are adopted to deliver data or information. In this paper, advantages of VLC, applications and development of VLC, challenges for VLC are provided.
