基于测量的典型工业物联网场景毫米波信道特性分析
Measurement Based Analysis on Millimeter Wave Channel Characteristics in Typical Industrial IoT Scenarios
摘要
Abstract
To better complement and expand the research on propagation characteristics of millimeter-wave radio frequency bands in typical Industrial Internet of Things(IIoT)scenarios and meet higher demands of IIoT in terms of connectivity,reliability,security,intelligence,and coverage,channel measurement and characteristic analysis were conducted in the 26 GHz frequency band for typical IIoT scenarios.Typical industrial scenarios involved in the research include industrial dense scenarios and industrial sparse scenarios with different equipment layout densities.Channel characteristic parameters are extracted from the measured data for both industrial en-vironments.Subsequently,the millimeter wave channel characteristics in two typical industrial scenarios are analyzed and compared.The findings indicate that in industrial dense scenarios,characterized by numerous metal devices,signals experience strong reflections leading to a lower path loss exponent compared to industrial sparse scenarios,as well as a smaller Rice K factor and greater delay ex-pansion.The utilization of phased array antennas for beam tracking at the receiver improves signal transmission efficiency and reduces propagation delay.Accurate analysis of the channel characteristics in IIoT scenarios is crucial for understanding signal propagation pat-terns in industrial environments,predicting and evaluating the transmission reliability of communication systems,thereby optimizing system design and network planning,and ensuring efficient and stable operation of IIoT applications.关键词
