| description | The objective of this work is to propose experimental path loss propagation models for communication channels in indoor environments. In this sense, an experimental path loss characterization has been achieved, according to the measurements campaign carried out in a typical scenario of a university campus. These narrowband measurements were collected in the laboratory environment at 3.7 GHz in line-of-sight (LOS) condition. Also, these measurements were carried out at night to simulate stationary channel conditions. Thus, the results obtained show the values of the parameters of the close-in (CI) free space reference distance and floating-intercept (FI) path loss models, in terms of the transmitter and receiver separation distance. It should be noted that these values of the path loss models have been extracted applying linear regression techniques to the measured data. Also, these values agree with the path loss exponent values presented by other researchers in similar scenarios. The path loss behavior can be described with the implementation of these models. However, more measurement campaigns are needed to improve the understanding of propagation channel features, as well as to obtain better precision in the results obtained. This, in order to optimize the deployment and performance of next fifth-generation (5G) networks that combine indoor environments to offer their services and applications. |

El objetivo de este trabajo es proponer modelos experimentales de las pérdidas de propagación para canales de comunicación en entornos indoor. Se ha efectuado una caracterización experimental de las pérdidas de propagación de acuerdo con la campaña de medidas llevada a cabo en un escenario típico de un campus universitario. Estas medidas fueron realizadas en un ambiente de laboratorio a 3.7 GHz en condiciones de línea de vista y con un enfoque de banda estrecha. Las mediciones se hicieron en la noche, simulando condiciones de estacionariedad del canal de comunicaciones. Los resultados obtenidos muestran los valores de los parámetros del modelo Close-In (CI) a una distancia de referencia en espacio libre, y del modelo Floating-Intercept (FI) en términos de la distancia de separación entre el transmisor y receptor. Se debe notar que dichos valores de los modelos de pérdidas de propagación se han extraído aplicando técnicas de regresión lineal a los datos medidos. Además, concuerdan con los valores del exponente de pérdidas de propagación presentados por otros investigadores en escenarios similares. Con la implementación de estos modelos se puede describir el comportamiento de las pérdidas de propagación en este tipo de entornos, sin embargo, es necesario hacer más campañas de medición para mejorar los conocimientos de las características del canal de propagación. También, para obtener una mejor precisión en los resultados obtenidos, con el fin de optimizar el despliegue y desempeño de las futuras redes de quinta generación (5G), que combinen los entornos indoor para la prestación de sus servicios y aplicaciones.
