Исследования выполнены с использованием основных положений и ансамблевых моделей статистической теории электромагнитной обстановки, а также базовых положений и моделей теории информации, определяющих пропускную способность радиоканала в условиях помех. Получены частотно- независимые соотношения для оценки ряда системных параметров сотовой связи в условиях интерференционного распространения радиоволн в городских каньонах и присутствия внутрисистемных радиопомех: оценки требуемой эквивалентной изотропно излучаемой мощности (ЭИИМ) абонентских станций, предельной пропускной способности обратного радиоканала, предельной дальности качественной связи, а также допустимого уровня внутрисистемных радиопомех при заданных требованиях к дальности связи и скорости передачи информации по обратному радиоканалу с учетом принятых ограничениях на ЭИИМ абонентского радиооборудования. Полученные соотношения позволяют оценить пределы возможных значений этих системных параметров современных иперспективных систем сотовой связи, а также обеспечивают возможность обоснования требований к качеству обеспечения внутрисистемной электромагнитной совместимости при требуемой скорости передачи информации в обратных радиоканалах сетей сотовой связи и имеющихся ограничений на ЭИИМ абонентских станций.</p></abstract><trans-abstract xml:lang="en"><p>The analysis was carried out in order to clarify the estimates of the expected restrictions on characteristics of new-generation mobile communications (4G, 5G) under the existing restrictions on radiated power of subscriber radio equipment, as well as in conditions where the boundaries of urban sites are outside of the area of free radio waves propagation (RWP) between subscriber and base stations. Analysis was performed using the basic principles and ensemble models of statistical theory of electromagnetic environment, as well as the basic principles of information theory that determines the radio channel capacity in presence of interference. Frequency-independent relationships have been obtained for estimating a number of system parameters of cellular communications under the conditions of multipath RWP in urban canyons and the presence of internal system interference: estimation the required equivalent isotropic radiated power (EIRP) of subscriber stations, the maximum data transmission capacity of the backward radio channel, the maximum distance of qualitative communication, and also the permissible level of internal radio interference at given requirements for communication range, and the information transfer rate of reverse radio channel taking into account the accepted restrictions on EIRP of subscriber radio equipment. The obtained relations allowus to estimate the limits of possible values of these system parameters of modern and future mobile communications; these relations also provide the opportunity to justify the quality requirements for ensuring the intra-system electromagnetic compatibility at the required data rate in backward radio channels of cellular networks and the existing restrictions on EIRP of subscriber stations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сотовая связь</kwd><kwd>электромагнитное излучение</kwd><kwd>системные характеристики</kwd><kwd>внутрисистемная электромагнитная совместимость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cellular communications</kwd><kwd>electromagnetic radiation</kwd><kwd>system parameters</kwd><kwd>intrasystem electromagnetic compatibility</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Propagation data and prediction methods for the planning of short-range outdoor radiocommunication systems and radio local area networks in the frequency range 300 MHz to 100 GHz.
