Aside from vast deployment cost reduction, Industrial Wireless Sensor and Actuator Networks (IWSAN) introduce a new level of industrial connectivity. Wireless connection of sensors and actuators in industrial environments not only enables wireless monitoring and actuation, it also enables coordination of production stages, connecting mobile robots and autonomous transport vehicles, as well as localization and tracking of assets. All these opportunities already inspired the development of many wireless technologies in an effort to fully enable Industry 4.0. However, different technologies significantly differ in performance and capabilities, none being capable of supporting all industrial use cases. When designing a network solution, one must be aware of the capabilities and the trade-offs that prospective technologies have. This paper evaluates the technologies potentially suitable for IWSAN solutions covering an entire industrial site with limited infrastructure cost and discusses their trade-offs in an effort to provide information for choosing the most suitable technology for the use case of interest. The comparative discussion presented in this paper aims to enable engineers to choose the most suitable wireless technology for their specific IWSAN deployment.

工业物联网的无线技术权衡调查。

除了大幅降低部署成本外，工业无线传感器和执行器网络（IWSAN）还引入了新的工业连接水平。工业环境中传感器和执行器的无线连接不仅可以实现无线监控和致动，还可以协调生产阶段，连接移动机器人和自动运输车辆，以及对资产进行定位和跟踪。所有这些机会已经激发了许多无线技术的发展，以全面实现工业4.0。但是，不同的技术在性能和功能上有很大的不同，没有一种能够支持所有工业用例。在设计网络解决方案时，必须意识到潜在技术的功能和取舍。本文评估了潜在的适用于IWSAN解决方案的技术，这些解决方案涵盖了基础设施成本有限的整个工业场所，并讨论了它们之间的权衡，以期提供信息，以便为感兴趣的用例选择最合适的技术。本文中进行的比较性讨论旨在使工程师能够为他们的特定IWSAN部署选择最合适的无线技术。
