Анализ интенсивности сигналов локальной беспроводной сети связи в смежных помещениях

Abstract

Refraction of electromagnetic waves plays a significant role in ensuring the wireless inside the building without direct visibility. The modeling of rays passage through the building walls is carried out with the purpose of the analysis of WLAN signals intensity in premises adjacent to the place of the access point location. The refraction of rays is considered in the approximation of geometrical optics. The algorithms for constructing the trajectory calculation of the intensity of the beam multiple refraction in the case of a predefined position access points and client network connection are designed. The procedure for constructing three-dimensional route is based on the calculation of the ray intersection points coordinates with each of the refractive surfaces, for which solved by a system of nonlinear algebraic equations. Presents some results, illustrating the efficiency of proposed algorithms in problems of estimating the share of the field, passing from adjacent premises in the global interference pattern of the WLAN signals intensity distribution.

Преломление электромагнитных волн играет существенную роль в обеспечении радиосвязи внутри здания в условиях отсутствия прямой видимости. С целью анализа интенсивности сигналов WLAN в помещениях, смежных с местом расположения точки доступа, выполнено моделирование прохождения лучей сквозь стены здания. Преломление лучей рассмотрено в приближении геометрической оптики. Разработаны алгоритмы построения траектории и расчета интенсивности луча многократного преломления в случае предопределённого положения точки доступа и клиента сети связи. Процедура построения трехмерной трассы основана на расчете координат точек пересечения луча с каждой из преломляющих поверхностей, для чего решается система нелинейных алгебраических уравнений. Представлены некоторые результаты, иллюстрирующие эффективность предложенных алгоритмов в задачах оценки доли поля, проникшего из смежных помещение, в общей интерференционной картине распределения интенсивности сигналов WLAN.
