Experimental validation of propagation models for radiocommunications applications in industrial environments

摘要

In this article, an overview is presented of the results obtained within a Project developed at Ansaldo (Naples, Italy) in the framework of the European Union's Human Capital and Mobility-Access to Large Installations Programme (E.U.Contract NO. CHGE-CT94-0066 European Commission-DGXII). The project aimed to characterise the radio propagation channel in an industrial environment. The way to do that consisted fundamentally of two phases: gathering a comprehensive set of measurements and a propagation modelling review. A deep knowledge of the limitations caused for an industrial environment will facilitate the setting up of the so convenient radio communications systems within industrial areas such as analogue trunked systems according to the MPT 1327 (400 MHz) standard, cordless systems according to the DECT (1800 MHz) standard or digital trunked systems, especially designed for voice and data applications, based on TETRA (400 and 900 MHz) standard
