Abstract:
The article considers authors - contribution in radiowaves propagation modeling, spatial distributions of radio channel physical characteristics and information transmission channel characteristics prediction and experimental studies, and electromagnetic radiation ecological significance assessment in inhabited environments. Joint use of geoinformational technologies, deterministic radiowaves propagation prediction models and deterministic methods for digital communication systems simulation enabled to develop powerful technology for creation of radioinformational models of inhabited environments, enabling to predict spatial distributions of information transmission channel characteristics (capacity, data rate, bit error rate). As the result of experimental studies, the applicability of Geometric Theory of Diffraction approximations for indoor radiowaves propagation modeling was approved in wide frequency range 200 MHz - 90 GHz. Developed deterministic (site-specific) methods of radiowaves propagation modeling demonstrated high accuracy (about 3 dB of signal level). The analysis, performed in the article, allowed to propose a general method of information transmission channel characteristics prediction, which satisfies modern and future tendencies in radio communication systems development. Approaches, developed by authors group, being based on construction of highly-detailed models of inhabited environments and communication systems, enable to solve a wide range of practical tasks, including digital wireless communication systems planning (optimal antennas placement, coverage calculation, technical requirements formulation and other), estimation of modern wireless communication systems influence on ecological conditions in certain inhabited territory, and optimization of ecological conditions of human living and his informational environment construction in given territory
