Industry 4.0 relies heavily on wireless technologies. Energy efficiency and device cost have played a significant role in the initial design of such wireless systems for industry automation. However, high reliability, high throughput, and low latency are also key for certain sectors such as the manufacturing industry. In this sense, existing wireless solutions for industrial settings are limited. Emerging technologies such as millimeter-wave (mmWave) communication are highly promising to address this bottleneck. Still, the propagation characteristics at such high frequencies in harsh industrial settings are not well understood. Related work in this area is limited to isolated measurements in specific scenarios. In this work, we carry out an extensive measurement campaign in highly representative industrial environments. Most importantly, we derive the statistical link-level distributions of the channel parameters of widely accepted mmWave channel model of IEEE 802.11 ad that fit these environments. This model can be beneficial to understand the performance of mmWave systems in typical industrial settings. Beyond analyzing and discussing the insights, with this article we also share our extensive dataset with the community.

工业环境中毫米波通信的信道测量活动

工业 4.0 严重依赖无线技术。能源效率和设备成本在用于工业自动化的此类无线系统的初始设计中发挥了重要作用。然而，高可靠性、高吞吐量和低延迟对于某些行业（例如制造业）来说也是关键。从这个意义上说，现有的工业环境无线解决方案是有限的。毫米波 (mmWave) 通信等新兴技术有望解决这一瓶颈。尽管如此，人们对恶劣工业环境中如此高频率的传播特性还不是很了解。该领域的相关工作仅限于特定场景中的孤立测量。在这项工作中，我们在极具代表性的工业环境中进行了广泛的测量活动。最重要的是，我们推导出适合这些环境的 IEEE 802.11 ad 的广泛接受的毫米波信道模型的信道参数的统计链路级分布。该模型有助于了解毫米波系统在典型工业环境中的性能。除了分析和讨论见解之外，在本文中，我们还与社区分享了我们广泛的数据集。
