MEDICIÓN, CARACTERIZACIÓN Y MODELAMIENTO DEL RANGO DE FRECUENCIAS ASIGNADO A SERVICIOS FIJO - MÓVIL (335 – 400 MHz) DE LA BANDA UHF DEL ESPECTRO ELECTROMAGNÉTICO EN LA FIEC, CAMPUS PROSPERINA

Abstract

This paper describes the details and analysis results of the radio spectrum measurements taken during a one-week period in the UHF band in the frequency range of 335 MHz – 400 MHz, in Guayaquil Ecuador at Escuela Superior Politecnica del Litoral from december 15 to december 22, 2014. This study allows us to identify the temporal occupational behavior and modeling of the analyzed electromagnetic spectrum. The results reflects that the weekly occupation of the spectrum is 2.10 % which occurs due to most of the band is restricted, then the 97.90% it is not busy. To verify the modeling of the frequency band that we arises, compared to a simulated in Matlab modeling, we can see that both the probability of the frequencies found in the state of occupied and are in the following state as unoccupied and the probability of the frequencies that are in the state and stay busy in the next state as occupied vary slightly from the experimental modeling. Using these results, we determined that there is a high availability on the monitored spectrum, which could be used for multiple telecommunication purposes. One of these purposes could be the usage on no reserved band, at which the propagation technical advantages may offer applications with a high quality of service and wide coverage, along with others.
