Análisis de factibilidad del diseño de radio enlace aplicando tecnología WRAN para brindar servicio de datos en la parroquia Teniente Hugo Ortíz (Pastaza).

Abstract

In this thesis Project, a prototype was developed to analyze the feasibility of a radio link to provide data service to the Teniente Hugo Ortiz Parish, located in the province of Pastaza, for which the USRP B-210 card provided by the Higher Polytechnic School of Chimborazo (ESPOCH). We used methodologies of application research and descriptive research, in the first theoretical knowledge was used to carry out the development of the design for the communication system, the second allowed to describe the reality of the community under study and analyze the characteristics and behavior that offers the system implementing. The Simulink software was used to generate, process, transmit and receive the signaly. Field tests were carried out through distance tests where the range of the designed radio link was determined. Then the reception capacity was determined; it was verified that the emitted message can reach up to 300 m from the transmitter, the distance reached is limited by the gain of the transmitter of 50 dBm and the sensitivity of the receiving equipment of less 76 dBm, in addition to the connection of the Universal Bus cable in series (USB) between the USRP B-210 card and the computer. With the development of this prototype it was possible to determine that the design of a radio link is possible as long as equipment with good characteristics of Radio Defined by Software (SDR) is available to have no scope limitations. It is recommended to make a prototype based on hardware to have better features and to carry out more real tests.
