白光LED的出现允许在一个光源中组合照明和信息广播功能。我们调查分析和蒙特卡罗模拟可行的数据传输速率在一个中等大小的办公室，在那里我们假设照明符合标准和使用市售的LED和光电二极管。依赖于基带的系统的性能[即，脉冲幅度调制（PAM）]和离散多音（DMT）传输表明，尽管系统的带宽相当低，但可以预期超过100 Mbit/s的数据速率。
Emergence of white-light LEDs allows the combination of lighting and information broadcast functionality in one optical source. We investigate analytically and by Monte Carlo simulations feasible data transmission rates in a moderate-size office room, where we assume illumination conforming to standards and the use of commercially available LEDs and photodiodes. The performances of systems relying on baseband [i.e., pulse-amplitude modulation (PAM)] and discrete multitone (DMT) transmission show that data rates of more than 100 Mbit/s can be expected despite the rather low bandwidth of the system.
