传统的无线通信方式在数据速率、频谱和可靠性方面都已饱和。可见光通信（VLC）与新兴的物联网（IoT）技术相结合，为广泛的室内应用开辟了道路。设备到设备通信需要可靠的上行链路沿着高速下行链路，其使用集成到设备中的LED和光电探测器。能源预算的短缺导致了VLC的节能变体的出现，即黑暗中的VLC，其在极低的照度水平下工作。它比传统的VLC消耗更低的能量，这使得它更适合物联网应用。VLC的目标是在自由空间链路上实现高达100 Gbps的传输速率。所提出的系统设计旨在通过结合不同方法的特征来克服传统VLC的局限性，例如黑暗中的VLC和通过使用QAM映射串行数据来使用OFDM进行数据传输。系统指定传输协议沿着发射器和接收器端电路。
Traditional methods of wireless communication are saturating in terms of data rate, frequency spectrum and reliability. Visible Light Communication (VLC) integrated with the emerging technology of Internet-of-Things (IoT) opens up to wide range of indoor applications. Device-to-Device communication requires reliable uplink along with the high speed downlink, which uses LEDs and photodetectors integrated into the device. Shortage of energy budget has led to emergence of the energy efficient variant of the VLC i.e. VLC in the dark, which works with extremely low level of illuminance. It consumes much lower energy than the conventional VLC, which makes it more suitable for IoT applications. VLC aims to achieve transmission rates of upto 100 Gbps over free space link. The proposed system design aims to overcome the limitations of traditional VLC by combining the features of different methodologies such as VLC in dark and use of OFDM for data transmission by mapping the serial data using QAM. The system specifies transmission protocols along with the transmitter and receiver end circuitry.
