Estudio comparativo de las tecnologías IEEE 802.11a y 802.11b de modo a mejorar el rendimiento de la red de datos. caso práctico: proveedor de internet FASTERCOM.

Abstract

The aim of this research work was to perform a comparative study of the IEEE 802.11a and 802.11b. The application study was carried out at FASTERCOM. The study comprises three nodes: main node, Llatantoma node and Lacon node. A theoretical comparison between the studied technologies IEEE 802.11a and 802.11b was carried out, analyzing indicators such as: transmission speed, propagation delay, latency, signal intensity, CCQ (client connection quality), etc. Simulations of testing scenarios of both main links were performed: Main Node-Llatantoma Node and Main Node-Node Lacon, employing Airlink online software. Each link was independently analyzed with IEEE 802.11a and with IEEE 802.11b technologies. The results showed a great advantage of IEEE 802.11a technology over IEEE 802.11b technology. Additionally, both technologies were implemented upon the data network of FASTERCOM internet provider, in both main links. The results showed an advantage of IEEE 802.11a technology on various indicators such as connection quality with the client, channel width, safety, etc. In chapter 4, a statistical study of the last mille, that is to say, in the client antennas of the enterprise was applied, this, due to that is the point where the internet service is used. Because of several data were collected from client antennas, it was necessary to calculate the sample to allow the application of the t-student for independent samples statistical test, which showed favorable results for IEEE 802.11a for all three indicators analyzed.
