Estudo de caso: avaliação da rede 802.11 nos prédios administrativo e acadêmico da Unipampa Alegrete

Abstract

In this work a case study of the 802.11 network of the administrative and academic buildings of the Unipampa campus Alegrete is presented. The purpose of this work is to carry out an analysis of the wireless network, verifying the level of signal, coverage and traffic speed, which can be generalized as a method for analysis in other buildings of Unipampa or, even for other wireless networks in similar environments. The paper presents a brief introduction to the existing 802.11 standards, which are the basis for wireless communication, and addresses the large-scale fading of electromagnetic signals together with propagation models that estimate the power level of a signal across space. The aforementioned models are the propagation loss model in free space and the log-normal loss model. The methodological description of the wireless network evaluation proposed in this work is presented together with the specifics of the structure. Analyzes of internal reports and equipment currently used are also carried out. Finally, the data obtained with the measurements and the indication of improvements in the wireless network are presented.
