A Comparative Study of Wireless Channel Propagation Characteristics in Industrial and Offce Environments

Abstract

This paper presents the comparative results of channel measurements in an industrial facility and an indoor office. The frequency domain channel measurements have been carried out in the frequency band of 0.8.2.7 GHz. Results on channel characteristic parameters such as large-scale path loss, shadowing, power delay profile (PDP), root-mean-square (rms) delay spread, Ricean K-factor and the multiple-input and multiple-output (MIMO) channel capacity measurements for indoor office and industrial scenario are presented and compared. The results indicate some different channel propagation characteristics of the industrial wireless channel from the indoor office channel owing to its different physical characteristics, which should take into consideration when designing robust industrial wireless communication system.
