Optical wireless systems with MIMO architecture in an industrial environment (OWIND)

在工业制造中，可以预见到广泛的应用，包括人工智能、增强现实以及单个产品的灵活生产调整。因此，未来的制造将需要具有高数据速率、低延迟和可靠连接的无线链路。光无线通信（OWC，也称为Li-fi）是一种使用免许可光谱的无线通信技术。LED灯具具有足够的调制带宽以实现高数据速率，并且每个灯具都可以用作无线接入点。网络化OWC增强型灯具将增加新功能，为工业生产构建无线网络。拟议项目将测量和建模多链路光无线信道，开发信号模型，包括具有强度调制的光发射器，具有直接检测的光接收器，并包括网络方面，如调制格式或软切换。将探讨多链路光无线信道的容量限制。将研究具有相互重叠的小小区的光无线网络的协调，以支持高数据速率的移动的用户。

A wide range of applications is envisioned for industrial manufacturing, involving artificial intelligence, augmented reality, as well as flexible production adjustments for individual products. Accordingly, future manufacturing will necessitate wireless links with high data rates, low latency and reliable connectivity. Optical wireless communication (OWC, also known as Li-fi) is a wireless communication technology using the unlicensed light spectrum. LED luminaires have enough modulation bandwidth for high data rates and each luminaire can be used as a wireless access point. Networked OWC-enhanced luminaires will add new features to build a wireless network for the industrial production.The proposed project will measure and model the multilink optical wireless channel, develop a signal model comprising also optical transmitters with intensity modulation, photo-receivers with direct detection and include network aspects such as modulation formats or soft handover. The capacity limits for multilink optical wireless channels will be explored. Coordination of the optical wireless network with mutually overlapping small cells will be studied for the support of mobile users at high data rates.
