In order to provide interactive capabilities within the context of Internet of Thing (IoT) applications, wireless communication systems play a key role, owing to in-herent mobility, ubiquity and ease of deployment. However, to comply with Quality of Service (QoS) and Quality of Experience (QoE) metrics, coverage/capacity analysis must be performed, to account for the impact of signal blockage as well as multiple interference sources. This analysis is especially complex in the case of indoor scenarios, such as those derived from Industrial Internet of Things (IIoT). In this work, a fully volumetric approach based on hybrid deterministic 3D Ray Launching is employed providing precise wireless channel characterization and hence, system level analysis of indoor scenarios. Coverage/capacity, interference mapping and time domain characterization estimations will be derived, considering different frequencies of operation below 6 GHz. The proposed methodology will be tested against a real measurement scenario, providing full flexibility and scalability for adoption in a wide range of IIoT capable environments.

为了在物联网 (IoT) 应用程序环境中提供交互能力，无线通信系统发挥着关键作用，因为其固有的移动性、普遍性和易于部署。但是，为了符合服务质量 (QoS) 和体验质量 (QoE) 指标，必须执行覆盖/容量分析，以考虑信号阻塞和多个干扰源的影响。这种分析在室内场景的情况下尤其复杂，例如源自工业物联网 (IIoT) 的场景。在这项工作中，采用了基于混合确定性 3D 射线发射的全体积方法，可提供精确的无线信道表征，从而提供室内场景的系统级分析。覆盖/容量，考虑到 6 GHz 以下的不同工作频率，将推导出干扰映射和时域表征估计。所提出的方法将针对真实的测量场景进行测试，为在广泛的 IIoT 能力环境中采用提供充分的灵活性和可扩展性。
