我们在此讨论光无线通信（OWC）系统是否可以成为后5G或6 G蜂窝通信的候选。几乎每十年，蜂窝移动的通信就会发生一次重大的演变，每一代人都会开发出一种独特的概念或技术。有趣的是，基于可见光和光保真度（Li-Fi）的OWC系统也出现了类似的趋势。不幸的是，OWC目前在任何5G场景中的作用都很有限，但这是否不可避免的争论尚未解决。在5G或6 G之后是否采用OWC并不是关键问题;相反，目标应该是OWC与5G和6 G通信技术共存。为了实现这一目标，OWC的研究和开发将继续扩大其优势，并使其系统标准化，以便在市场上广泛部署。例如，鉴于已经存在用于可见光信标标识符和Li-Fi的标准，应该开发使用该标准的服务以满足用户需求。为此，我们在此提出了一种用于可见光信标识别的方法，该方法涉及使用卷帘快门来接收与智能手机相机的可见光通信。此外，我们还介绍了一种用于图像传感器通信的旋转LED发射器。
We discuss herein whether an optical wireless communication (OWC) system can be a candidate for post 5G or 6G cellular communication. Almost once per decade, cellular mobile communication is transformed by a significant evolution, with each generation developing a distinctive concept or technology. Interestingly, similar trends have occurred in OWC systems based on visible light and light fidelity (Li-Fi). Unfortunately, OWC is currently relegated to a limited role in any 5G scenario, but the debate whether this is unavoidable has yet to be settled. Whether OWC is adopted post 5G or 6G is not the vital issue; rather, the aim should be that OWC coexists with 5G and 6G communication technologies. In working toward this goal, research and development in OWC will continue to extend its benefits and standardize its systems so that it can be widely deployed in the market. For example, given that a standard already exists for a visible-light beacon identifier and Li-Fi, a service using this standard should be developed to satisfy user demand. Toward this end, we propose herein a method for visible-light beacon identification that involves using a rolling shutter to receive visible-light communications with a smartphone camera. In addition, we introduce a rotary LED transmitter for image-sensor communication.
