Diseño e implementación de un radioenlace para evaluar el rendimiento de los protocolos NV2 y NSTREME en la provisión de internet en la comunidad Guarguallá.

Abstract

The objective of this curricular integration work was the evaluation of the performance of the wireless protocols, NV2 and Nstreme, by means of the Mikrotik company's own tools, in terms of bandwidth, response time and percentage of packet loss, for which It was necessary to design and implement a radio link, from the Rayoloma to Guarguallá node, belonging to the Internet service provider company Intertec. The radio link design began with a frequency sweep with the spectrum analyzer in the free 5GHz band, after which it was simulated using Radio Mobile, considering technical details of the selected equipment, which provided essential parameters for the implementation, finally In the design, the availability of the link was calculated due to attenuation effects caused by rain, having a high availability. The implementation was carried out after planning and configuring the equipment, which, once the link was validated, allowed the application and evaluation of the Nv2 and Nstreme protocols in different standards and channels. The two protocols were evaluated with Mikrotik's own tools, resulting in a better behavior with Nv2 in bandwidth, reaching a maximum capacity of 143.3 Mbps upload and 112.4 Mbps download, a lower response time in Nv2 with latencies of less than 20 ms and verifying a lower amount of packet loss in Nv2 with a saturated channel. It is concluded that the Nv2 protocol offers better performance compared to the Nstreme protocol in each of the evaluated variables, despite the fact that a higher CPU consumption was identified in the measurement equipment. It is recommended to use evaluation tools other than the brand itself, which allow the evaluation of network parameters, without compromising the processing consumption of the radio link equipment.
