Evaluación del rendimiento de dispositivos Access Point, mediante el uso de mecanismos de conectividad en redes con alta concurrencia de usuarios.

Abstract

The purpose of this research was to improve the performance of access point devices in networks with high concurrency of users using connectivity mechanisms. These where analyzed and later selected as the most outstanding and most used devices at the Central University of Ecuador. According to the study, the IEEE 802.11N and 802.11AC Standards were chosen, which have measurement parameters such as bandwidth, throughput, latency, jitter, noise, signal strength, and connection quality, among others. Then simulations were performed in the tools Cisco Prime Infrastructure and Cisco 8500 Series Wireless Controller. In these tests, standars in mention were execute, measuring parameters such as configured speed rate, traffic, throughput, signal strength, connection quality or noise, channel utilization and interference. Obtaining possible criteria about the best mechanism of connectivity, once evaluated, give results-oriented towards the standard IEEE 802.11N. Finally, through the Student T statistical analysis for independent samples, a sample is taken for each standard. The results of the evaluated indicators are determined with the following values, signal strength 60.88 dBm for 802.11N and -65.64 dBm for 802.11AC, connection quality 29.19 dB for 802.11N and 26.24 dB for 802.11AC and throughput 4953.60 kbps for 802.11N and 3296.93 kbps for 802.11AC, data that identify and demonstrate the superiority of the wireless network performance with the 802.11N standard. And as an endpoint, specific criteria are issued as a guide to economic characteristics, physical location, software, and command configuration that must have access points to work optimally and therefore alloy high performance in the wireless network.
