This article describes a study on a model for radio propagation in a land mobile communication (LMC), which differs from models based on the well-known theory for tropospheric propagation. The new propagation model has been constructed from a phenomenological, point of view for an LMC in an area where artificial or natural obstacles are present. This new model is based on evidence that the clearance of the propagation Baths is lost and the signal received by a mobile station is very weak. The model is constructed by means of the meson field, from an analogy between the interaction of nucleons and the mobile communication between stations, lying in an area with artificial or natural obstacles. The application of this meson field model. to experiments of radio propagation in LMC, made in areas with artificial or natural obstacles, shows that the field intensity level can be described by the model in the entire range of the distance. The study also shows that the LMC, mentioned above, should be considered as a communication, in which stations do not communicate with one another by a Hertzian wave, but by a wave-packet, having an energy not directly dependent on the frequency of a signal. The meson field model, at present, cannot be employed as a technique for predicting the field intensity level, since constants accompanied by the model are not obtained for given conditions such as antenna heights, terrain irregularities and so forth.
