Diseño de una red de comunicación inalámbrica para la transmisión de la información de las estaciones metereológicas del Centro de Investigación de Energías Alternativas y Ambiente.

Abstract

The aim of the research was to design a telecommunications network that would allow the transmission of the information generated at each meteorological station administered by the Center for the research of alternative energies and environment (CEAA) towards the Escuela Superior Politécnica de Chimborazo (ESPOCH). A cross-border study was conducted on longrange wireless communication technologies. WiMAX Technologies, Radio link and General Service of packets via radio (GPRS) were analyzed for possible use in the technical proposal. For WiMAX was used the software ICS Telecom, for Radio link the Web tool Air-link, for GPRS, on the website corresponding to each operator was determined that Otecel and the National Telecommunications Corporation (CNT) have coverage in each locality . By using a scale of Likert, it was determined that the most suitable technology for the development of the project was GPRS. The Sierra FXT009 modem was chosen for file sending. In the communication between the modem and the Datalogger, the software Maws Lizard is used to obtain the transmission of files it is used the software of the manufacturer Open AtAf. To determine the results of the operation of the proposal, a prototype was implemented using an Arduino and a SIM900 card, making use of the CNT operator from which 4 files were sent. On the server side was made an Internet traffic capture by using the Wireshark software. This capture was further analyzed in the Colasoft CAPSA software with which additional results were obtained. The average transfer rate was 8.41 Kbytes per second. Compared to the current information-gathering methodology, this study's proposal is more efficient in meeting this task. In the future it is recommended to take into account safety aspects of the transmission.
