New propagation model for wireless monitoring systems in the container terminal environment

The problem of the propagation loss calculation of the mobile radio links working in container terminal areas has been analyzed. The analysis is based on the measurement investigations of the radio signal loss made for different propagation conditions of the container terminal environment. Two main types of the propagation environment have been take into account - i.e. LOS and NLOS conditions, as typical for the environment classification. New empirical formulas for the propagation loss calculations appropriate to these types of the propagation environment have been proposed. To obtain these formulas the measurement investigations have been made and the multidimensional regression analysis has been applied. The new propagation model has been verified by use of the measurement investigations. Finally, practical usefulness of the model for design procedures of the radio links in the container terminal areas has been concluded.
