ENVIRONMENTAL EFFECTS ON SHORT-RANGE COMMUNICATIONS,
Abstract
The report discusses the following topics: (1) electro-geographical classification systems, which concerns means of classifying topographical, geological, and vegetative features in electrically meaningful terms and to provide means of determining appropriate electrical properties from botanical, climatological, geological, and similar information, (2) electrical properties measurement techniques, which concerns determining available and potential techniques for measuring effective electrical properties of various types of terrain and the influence of surface conditions and terrain irregularities on these properties, and determining practical means of documenting the results of such measurements, (3) mathematical and physical modeling, which concerns determining the adequacy of presently available models for predicting overall radio pathloss, making recommendations for future work on mathematical models, and considering the feasibility and advisability of the development of physical scale models to simulate environmental effects on electromagnetic propagation, and (4) review of present programs for measuring radio waves propagated over the earth's surface, through the atmosphere and via the ionosphere and recommendations for type, location, and extent of future measurement programs needed or desired.
