It is particularly important to look for any propagation model that could be useful for designing mobile radio networks in container terminal environment. Selected propagation models have been investigated. Firstly – basing on measurements results – they have been evaluated in this scope and the analysis has shown, that the adjustment is needed. This modification improved significantly the accuracy of path loss modelling. For the best adjusted model – ITU-R P. 1411 described in §4.2.2 – the mean error equals -0.1 dB, the standard error of estimate equals 5 dB, and the coefficient of determination is 0.785. These results mean that the adjusted model fits very well to experimental data.
