Evaluación de una alternativa de una red de microondas terrestre para la transmisión de datos provenientes de las redes de monitoreo y observación instaladas en Esmeraldas, Manabí y Carchi, hasta el centro de procesamiento de información del Instituto Geofísico

Abstract

The objective of the present study is to evaluate an alternative of a terrestrial microwave network for the transmission of data from the monitoring and observation networks installed in Esmeraldas, Manabí and Carchi, to the Center for Information Processing and Seismic and Volcanic Alerting of the “Instituto Geofísico de la Escuela Politécnica Nacional (IGEPN)”. It starts describing the microwave systems, disturbances that affect these systems; phenomena, properties and technical aspects that must be studied in microwave propagation, the main components of these systems, and digital modulation schemes that can be implemented. After that, it describes the current situation of the transmission networks of the IGEPN in the mentioned provinces. For the evaluation of this terrestrial microwave network alternative, minimum requirements have been established for its design, like assignments of frequency bands for its operation, identifying appropriate sites for the location of the infrastructure and the minimum technical parameters of operation. Finally, it makes a proposal of the appropriate equipment, describing and making a comparison of the costs of three manufacturers, and it provides estimated information of a general budget for the installation, maintenance and operation of this network.
