Estudio comparativo de la implementación de un portal cautivo mediante las tecnologías Mikrotik y Cisco para mejorar el rendimiento de una red inalámbrica en MiPyMES.

Abstract

In the present work a comparative study was carried out between the Cisco and Mikrotik technologies for the implementation of a captive portal in order to improve the wireless network performance in a micro, small and medium enterprise (MIPYMES). Features of existing devices on the market were studied, taking into account the needs of the wireless network infrastructure of the IPREX academic preparation institute. A qualitative analysis was performed by comparing subjective evaluation parameters, resulting in the Mikrotik RouterBoard RB750G device being the most suitable for the implementation of the captive portal with an average of 82% of subjective parameters versus 75% obtained by The Cisco WAP 131Wireless-N Dual Radio Access Point device, which was followed by the implementation of Mikrotik technology. Subsequently, network traffic analysis was performed before and after the implementation of the captive portal, resulting in a loss of packets of 24,581% without captive portal vs 12.192% with captive portal, evidencing an improvement of 12.389%; A jitter of 8.93 ms without captive portal vs 6.02 ms with captive portal, demonstrating a reduction of 2.90 ms; Delay of 122.3 ms without captive portal vs 46.9 ms with captive portal, obtaining a reduction of 75.4 ms, and 30% total optimization. There was a 6% improvement in user experience (MOS). It is concluded that the implementation of captive portal in the IPREX wireless network, with the device Mikrotik RouterBoard RB750G, is a reliable solution for the control of resources and the number of users. IPREX is recommended to consider the implementation of the Internet service using fiber optics, with a greater availability of 4Mbps of bandwidth to improve the speed of the Internet and increase the number of users of the captive portal service.
