可见光通讯（英语： Visible Light Communications ，缩写为 VLC ），是一种光通讯方式，利用萤光灯或发光二极管（LED）等物体发出的明暗闪烁信号来达成讯息传输的通信技术。 可见光的频率介于400 THz（波长780 nm）至800 THz（波长375 nm）之间。使用普通的日光灯时，它的传输能力为10 kbit/s。
Visible light is only a small portion of the electromagnetic spectrum.. In telecommunications, visible light communication (VLC) is the use of visible light (light with a frequency of 400-800 THz/wavelength of 780-375 nm) as a transmission medium.VLC is a subset of optical wireless communications technologies.. The technology uses fluorescent lamps (ordinary lamps, not special ...
可見光通訊（英語： Visible Light Communications ，縮寫為 VLC ），是一種光通訊方式，利用螢光燈或發光二極體（LED）等物體發出的明暗閃爍信號來達成訊息傳輸的通信技術。 可見光的頻率介於400 THz（波長780 nm）至800 THz（波長375 nm）之間。使用普通的日光燈時，它的傳輸能力為10 kbit/s。
1 可见光通信的原理及技术背景 . 可见光通信技术 (visible light communication，VLC)，是利用发光二极管(light emitting diode，LED)等 可见光光源 发出肉眼难以分辨的高速明暗变化光信号来传输信息。 如图1所示，以二进制开关键控(On-Off keying，OOK)信号传输为例，如果让光强"亮"代表数字通信中的"1"，让光 ...
During the last decade, the exponential growth of mobile devices and wireless services created a huge demand for radio frequency-based technologies. Meanwhile, the lighting industry has been revolutionized due to the popularization of LED light bulbs, which are more economical and efficient. In that context, visible light communication (VLC) is a disruptive technology based on LEDs that offers ...
可见光通讯（英语：Visible Light Communications，缩写为VLC），是一种无线通讯技术，是利用荧光灯或发光二极管（LED）等物体发出的明暗闪烁信号来实现信息传输的通信技术，可见光的频率介于400 THz（波长780 nm）至800 THz（波长375 nm）之间。使用普通的日光灯时，它的传输能力为10 kbit/s。
Visible light Communication is a subdivision of Optical Wireless Communication technology. In this technology it is used as fluorescent lamps to transmit signal at 10kbit/s and LED is used to transmit 500Mbit/s over a small distance. VLC can be used as transmission medium for all over the place computing, because light producing devices (such as
于是，为了和光纤通信进行区分，我们的"真·光通信"又被叫做"可见光通信"（Visible Light Communication，VLC）。它有属于自己的标准——IEEE 802.15.7 VLC。 它的准确定义是：利用可见光波段的光作为信息载体，在空气中直接传输光信号的通信方式。
可見光通信（visible light communications，VLC）是用肉眼可看到的唯一『無線通信』信號，是利用螢光燈或發光二極體(LED)等發出高速明暗閃爍信號來傳輸 ...
Visible Light Communication (VLC) systems employ visible light for communication that occupy the spectrum from 380 nm to 750 nm corresponding to a frequency spectrum of 430 THz to 790 THz as shown in Fig. 2.The low bandwidth problem in RF communication is resolved in VLC because of the availability of the large bandwidth as illustrated in Fig. 2.
