Redes sem fio: projeto de uma rede corporativa

Abstract

IEEE 802.11 networks became a reality because of the many advantages they offer for installation, for example, low cost, speed of implementation and the fact that minimal specialist knowledge is required because most of the equipment comes pre-configured from the factory. All these factors have led to increased use of network resources and have caused a series of problems, such as a large concentration of users at overloaded access points or problems when controlling a large number of access points which are distant from the management areas. The greatest problems of wireless networks are management and security. Due to their nature, these networks travel in a physical environment which is susceptible to attacks from malicious users, and the necessary action to provide sufficient security and management have not been carried out quickly enough or the administrators have lacked the knowledge to do so. The aim of this paper is to present a proposal of a configuration and implementation methodology for corporative wireless networks that can serve as a guide for new installations.
