下一代工业控制系统将需要能够提供极低延迟、超高可靠性和高数据速率的高性能无线网络（称为WirelessHP）。目前实现工业无线网络的策略是采用通用无线标准的底层，只对上层进行定制。本文提出了一种新的自下而上的方法，通过实现无线shp物理层，专门针对通过最小化分组传输时间来减少通信延迟。理论分析表明，与通用的IEEE 802.11物理层相比，所提出的设计允许数据包传输时间大幅减少，减少到1 $ $ $ s。通过实验验证了该设计，结果表明该物理层可实现20 m范围内的可靠通信。
The next generations of industrial control systems will require high-performance wireless networks (named WirelessHP) able to provide extremely low latency, ultrahigh reliability, and high data rates. The current strategy toward the realization of industrial wireless networks relies on adopting the bottom layers of general purpose wireless standards and customizing only the upper layers. In this paper, a new bottom-up approach is proposed through the realization of a WirelessHP physical layer specifically targeted at reducing the communication latency through the minimization of packet transmission time. Theoretical analysis shows that the proposed design allows a substantial reduction in packet transmission time, down to 1 $\mu$ s, with respect to the general purpose IEEE 802.11 physical layer. The design is validated by an experimental demonstrator, which shows that reliable communications up to 20 m range can be established with the proposed physical layer.
