Revisión al Desarrollo de la Tecnología de Radio Cognitiva en Bandas VHF – UHF en el Ecuador

Abstract

Review of the Development of VHF-UHF Band Cognitive Radio Technology in Ecuador Gradual demand, overuse and under-utilization of the spectrum are factors that have denoted, at the government and research levels, a search for legal and technological solutions to optimize the use of the radio spectrum. Under this argument, the document addresses a review of the state of the art on the application of Cognitive Radio (CR) technology on Cognitive Wireless Sensor Networks (CWSN) or spectral reuse for the improved exploitation of the radio spectrum in VHF - UHF bands in Ecuador. This collection or observation would allow the identification of the state of the art for the development of the research project "Smart UNL" that intends to deploy a network of wireless sensors based on Cognitive Radio (CR) for control of luminaires within a Smart Campus. The results show that the fundamental concept of CR for this type of application is not being exploited since the researched work is oriented towards other types of CR telecommunications studies, which suggests a wide field of application and development of CWSN for the possible management and control of components of a Smart Campus.
