可见光通信可见光通信(英语:Visible Light Communications,缩写为VLC),是一种无线通信技术,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。使用LED灯时,则可以到达500 Mbit/s。传输距离则可以到达1-2公里。它最大的特色是可以结合固态照明技术。 可见光通信可以应用于光照上网、可见光点播电视业务、可见光新型无线广播、可见光精确定位等领域。

Visible light communication 可见光通讯![]() Visible light communication (VLC) is a data communications medium which uses visible light between 400 and 800 THz (780–375 nm). VLC is a subset of optical wireless communications technologies. The technology uses fluorescent lamps (ordinary lamps, not special communications devices) to transmit signals at 10 kbit/s, or LEDs for up to 500 Mbit/s. Low rate data transmissions at 1 and 2 kilometres (0.6 and 1.2 mi) were demonstrated. RONJA achieves full Ethernet speed (10 Mbit/s) over the same distance thanks to larger optics and more powerful LEDs. |
