Abstract

There has been recent interest in characterizing UHF propagation within buildings and houses. Factory radio channels, however, have not been discussed previously in the literature. This paper details the results of narrow-band propagation measurements performed at five factories. The extensive empirical data indicate that path loss is dependent upon local surroundings and is log-normally distributed, temporal fading is Rician, and small-scale signal fluctuations due to receiver motion are primarily Rayleigh, although Rician and log-normal distributions fit some of the data. Shadowing effects of common factory equipment likely to obstruct indoor radio paths are also given here.
