PLC系统为环境及经营者带来利益
G3-PLC提供了一套简便的路灯网络通信方案，双向通信支持自动化设计更高要求：
根据地理位置、日历及天气条件确定打开/关闭照明系统的准确时间
黎明/黄昏和深夜适当调整照明亮度
通过调光进行交通管制
交通监测
路灯故障报警
基于温度、电流、PF或工作小时数通报路灯维护时间
紧急打开/关闭/控制照明亮度
实时监测能耗
相对于无线通信系统，PLC具有众多优势。PLC系统同样不需要重新铺设电缆，而且，PLC通信可以穿过地面、墙壁进行数据传输。信道归经营者或电力公司所有，不存在频带冲突的风险。PLC不存在视距限制，也不受天气影响。此外，由于PLC使用电力线通信，能够检测到线路故障及其发生故障的大概位置。
隧道照明：PLC设计案例
PLC能够降低能耗和运营费用，而且*，我们以一个新型PLC系统为例进行说明。该项技术目前已被Nyx Hemera Technologies公司用于隧道照明。相对于荧光灯系统，隧道照明控制系统（TLACS）能够节能25%，维护费用降低30%。将照明强度调整到与隧道入口及出口环境相同光强，大大提高了安全性。
TLACS系统基于Maxim Integrated Products提供的OFDM PLC产品，即使信号电平比噪声低，也能通过远距离电力线传输后收到严重衰减的信号。Maxim方案的寻址能力和高数据率使Nyx Hemera Technologies公司能够利用单套系统支持多达1022盏灯。TLACS系统支持3km的传输距离，由于采用电力线传输，可以选择模块化设计，很容易安装到现有的照明系统（图1）。
