A comparison of measured and predicted, 800 MHz, land-mobile-radio signals

The details of a UHF propagation measurement program are presented. A mobile vehicle is equipped with a receiver that is capable of measuring the available power from a roof-mounted vertical monopole antenna. The measurements are performed over rural terrain while the vehicle is in motion. The basic transmission loss for the route traveled is plotted along with a prediction produced by an irregular terrain propagation model. This comparison demonstrates the applicability of the model to the land-mobile environment.
