Metodología para la localización de TV White Spaces en zonas rurales del Distrito Metropolitano de Quito mediante el uso del software de planificación de red ICS Designer

Abstract

In the present project a methodology was implemented to represent the location of television White Spaces in rural areas of the DMQ (Metropolitan District of Quito) using a radio frequency planning tool. The methodology starts with a documentation phase of the required parameters to simulate the current radio electric environment in the DMQ. These parameters are then entered into the ICS Designer software to obtain the coverage of the analogue open television transmitters and then identify the TV White Spaces in the rural study areas based on the decision threshold set for each portion of the spectrum. Finally, a spectral analyzer is used to perform the field validation of the most extensive White Spaces found in order to compare the simulated values with the measured values, and based on this, to classify as TVWS zones those in which they are evidenced values of electric field strength below the threshold. This study is important because with the identification of TV Spaces White we can use Cognitive Radio as a solution to the current lack of free space in the radioelectric spectrum for the deployment of new services or to improve existing ones.
