Análise da confiabilidade da transmissão de sinal de banda larga de uma empresa de telecomunicações

Abstract

Each time the necessity of using information systems by people and public and private companies becomes indispensable in order to determine the companies reliableness, as well as, finding improvements points within a signal transmission system of internet services is of main importance to a company which is reference in this sector, continue as the leader and keep its clients satisfied. To that purpose, this paper proposed to make the mapping of the internet signal transmission system, which is distributed via cable, by the company, Net Serviços de Comunicação, in Bagé/RS, by conducting a quantitative survey in such field, with identifying faults generated in the Internet transmission system, in which the data from the period between September/2012 and August/2013 was used as parameter, and, to make it possible, it was used the Failure Tree Analysis (FTA) tool, that mapped the failures occurred in that period, and that resulted in the elaboration of the system failure tree. As a result, it was detected the main events that caused the interruption of internet signal, and that propitiated a reflection regarding the possible measures to prevent or reduce such undesirable events, and thus, increase the reliableness of the system.
