WIA-FA and IEEE 802.11 are two most widely adopted industrial wireless standards in discrete manufacturing. However, comprehensive performance comparisons between WIA-FA and IEEE 802.11 are still missing and industrial applications urgently need experimental methods to guide the selection of appropriate wireless technologies. To this end, this article performs extensive experiments between WIA-FA and IEEE 802.11 in two practical industrial scenarios, with one ordered scenario defining the transmission order of devices and the other order-free scenario imposing no order constraints to the transmission order of devices. Network performance indices of the WIA-FA and IEEE 802.11 networks, including reliability, delay, jitter, and disorder rate, are compared for different network sizes and data generation periods. Experimental results show that the WIA-FA protocol provides stable network performance, while the network performance of the IEEE 802.11 protocol is random and uncontrollable. Additionally, we perform preliminary comparisons of WIA-FA with IEEE 802.11ax and 5G New Radio.

用于离散制造的 WIA-FA 和 IEEE 802.11 网络的实验评估

WIA-FA 和 IEEE 802.11 是离散制造中两种最广泛采用的工业无线标准。然而，WIA-FA 和 IEEE 802.11 之间的综合性能比较仍然缺失，工业应用迫切需要实验方法来指导选择合适的无线技术。为此，本文在两个实际的工业场景中对 WIA-FA 和 IEEE 802.11 进行了大量实验，一个有序场景定义了设备的传输顺序，另一个无序场景对设备的传输顺序没有顺序约束。针对不同的网络规模和数据生成周期，比较了 WIA-FA 和 IEEE 802.11 网络的网络性能指标，包括可靠性、延迟、抖动和无序率。实验结果表明，WIA-FA协议提供稳定的网络性能，而IEEE 802.11协议的网络性能随机且不可控。此外，我们还对 WIA-FA 与 IEEE 802.11ax 和 5G 新无线电进行了初步比较。
