Abstract: It was originally analytically solved the problem of field distribution of a narrow-directed MM-wave beam behind obstacle. Experiments proved anticipated field levels that are 40 dB higher than the levels of omni-directed decimeter (DM) radiation. It was proposed and verified in series of measurements the model of forming of interference structure of MMW beam field in a shadow of vegetation, versus vertical receiver movement. Taking into account MMW beam peculiarities, it was demonstrated the advantages of frequency re-use increasing efficiency in digital cellular network in comparison with existing DM systems, in application to mobile telecommunications and fixed wireless access. !14
