The ever-growing demands from emerging industrial applications and services require revolutionary technology beyond fifth-generation (5G). The sixth-generation (6G) networks are the promising technology to satisfy the high data rate demands for future industrial applications. This paper examined wideband radio propagation characteristics at 28 GHz obtained through measurements in an industrial environment and compared them with those obtained at 108 GHz. The characteristics were expressed in terms of path loss, K-factor, power delay profile, root mean square delay spread, and channel capacity. The measured path-loss was used to obtain empirical propagation models in the line of sight using the floating intercept and close-in free space reference distance and they fitted very well. The obtained propagation models were then used to obtain an empirical channel capacity prediction model in terms of antenna gain, transmission frequency, distance, and propagation exponent. For the non-LoS scenario, significant degradation of channel capacity was observed, and hence the usage of intelligent reflection surface technique to compensate for the lost capacity was investigated. This work is part of the foundation needed to establish the feasibility of using IRS technique in 6G networks operating at mmWave and sub-THz bands for industrial applications.
