Sistema de telecomunicaciones ROIP (Radio Over IP) con la fusión de las tecnologías analógicas y digitales para mejorar la comunicación entre los radioaficionados del Ecuador

Abstract

This project is about the design and construction of the radio telecommunication system with the integration of voice over IP technology (VOIP) in order to provide transceiver equipment (radios) with advanced capabilities in coverage and therefore improving communication among Amateur Radio of Ecuador. Within telecommunications system ROIP (Radio Over IP), the radio base station (transceiver) is connected to a PC (Raspberry Pi), via a universal type of hardware interface (connection to any type of radio), so establishing communication between the base radio with PC. The PC has weezy Debian Linux 7.0 operating system on which EchoLink (svxlink server) radio software that allows you to manage and configure the ROIP system installed. For the evaluation of the results Wireshark tool was used in order to the monitor and capture traffic flow several calls established among the Amateur Radio of Radio Over IP. Using a script the QoS parameters and measurements of signal to noise ratio (SNR) in the RF were determined, and together through an oscilloscope the signal level was checked with respect to the noise, resulting that quality of Service (QoS) matches with RFC -3246 (Cisco QoS) recommendation.
