Abstract
Se evaluó los parámetros obtenidos en el software Radio Mobile en dos diseños de sistemas de radioenlace punto a punto, determinando dos eventos específicos entre las antenas del sistema. Previamente se realizó el diseño de ambos sistemas dando una geolocalización específica de coordenadas, se obtuvieron datos y se compararon pérdidas de trasmisión entre las antenas, específicamente en la zona Fresnel de los sistemas incorporados. Mediante la simulación de ambos sistemas se realizó la comparación tomando la mejor zona Fresnel y la peor zona Fresnel en cada radioenlace, se describió el funcionamiento e importancia que se debe tener al implementar un sistema punto a punto, tomando en consideración una simulación que pueda predecir la eficacia de la transmisión de datos en estos sistemas. Se demostró mediante respaldo, fórmulas matemáticas y trayectoria de Huygens con las cuales se basa el software Radio Mobile para los resultados de la simulación. Se analizó la comparación establecida mediante parámetros y tomando de las diferentes capas segmentadas en la zona Fresnel la mejor y peor zona, colando obstáculos naturales en un sistema, y sin obstáculos en el otro. Se examinó las simulaciones mediante otro software de diseño de radioenlaces como lo es AirLink de Ubiquiti, demostrando una representación gráfica y una referencia de la calidad de transmisión de datos. Los resultados fueron los esperados, demostrando la eficacia de los radioenlaces punto a punto cuando se encuentran sin obstáculos naturales en la zona Fresnel. El sistema con obstáculos tuvo una ineficacia en la transmisión de datos, se respaldó dicha información mediante el método de correlación de Pearson, obteniendo una correlación positiva en las comparaciones realizadas.
The parameters obtained in the Radio Mobile software were evaluated in two designs of point-topoint radio link systems, determining two specific events between the antennas of the system. Previously, the design of both systems was carried out, giving a specific geolocation of coordinates, data were obtained and transmission losses were compared between the antennas, specifically in the Fresnel zone of the incorporated systems. Through the simulation of both systems, the comparison was made taking the best Fresnel zone and the worst Fresnel zone in each radio link, the operation and importance that must be had when implementing a point-to-point system was described, taking into consideration a simulation that can predict the efficiency of data transmission in these systems. It was demonstrated by support, mathematical formulas and Huygens trajectory on which the Radio Mobile software is based for the simulation results. The comparison established by parameters was analyzed and taking the best and worst zone from the different segmented layers in the Fresnel zone, straining natural obstacles in one system, and without obstacles in the other. The simulations were examined using other radio link design software such as AirLink Ubiquiti, demonstrating a graphical representation and a reference of the data transmission quality. The results were as expected, demonstrating the effectiveness of point-to-point radio links when they are without natural obstacles in the Fresnel zone. The system with obstacles had an inefficiency in the transmission of data, said information was supported by the Pearson correlation method, obtaining a positive correlation in the comparisons made.
