摘要

通过微小的外部修改,实现了可见光通信(VLC)系统的升级,包括其自身的磷光发光二极管(PH-LED)的商业灯。该灯现在在具有强背景光(高达~ 3000 lx)和高偏差容忍度(高达45度)的环境中,通过非定向视距(NDLOS)链路提供以太网10Base-T传输。通过对随机生成的数据包进行丢包测量,以及在NDLOS中对曼彻斯特编码OOK信号在1米距离上传输的等效以太网12.5 Mbit/s的误码率(BER)测量,对系统的运行进行了测试。该技术已应用于商业照明设备,无需对灯具进行任何相关修改。

Ethernet over commercial lighting by a Visible Light Communication
A Visible Light Communication (VLC) system was realized upgrading, via minor external modifications, a commercial lamp including its own Phosphorescent Light Emitting Diode (PH-LED). The lamp now provides an Ethernet 10Base-T transmission over a Non-Directed Line-Of-Sight (NDLOS) link in an environment with strong background light (up to ∼3000 lx) and high tolerance to misalignment (up to 45 degrees). The system operation has been tested with packet loss measurements of randomly generated packets and with Bit Error Ratio (BER) measurements of an Ethernet-equivalent 12.5 Mbit/s transmission of a Manchester coded OOK signal over a distance of 1 m in NDLOS. The proposed technology has been implemented into a commercial lighting equipment without any relevant modification of the lamps.
