This paper presents a comparative investigation of channel measurements and corresponding channel characteristics at 28 GHz, 38 GHz and 132 GHz in two different industrial environments, including a micro drilling-milling area and a large milling area. To depict the channel characteristics in industrial environments accurately, the close-in free space path-loss model and the alpha-beta-gamma model are used to examine path loss. Additionally, we analyze and compare the root mean square (RMS) delay spread (DS) and angular spread (AS) in different areas. The findings indicate the path loss exponent (PLE) has a dependency on the frequency, and all PLEs are less than the free space value 2.0 for the LoS case. Furthermore, RMS DS and AS exhibit distinct characteristics across various environments. This research provides valuable insights for design and optimization of industrial environmental systems.
