Travaux pratiques sur les r\'eseaux locaux de type WIFI utilisant des simulations num\'eriques des ph\'enom\`enes de propagation des ondes \'electromagn\'etiques

Abstract

The wireless network technology WiFi finds more and more applications in the industrial field as for the exchange of information between the people or the equipment. It has the advantage of allowing a great flexibility of the network but requires precautions of installation to be effective (flow, reliability...). The fitter of such a network must have knowledge to install and configure the materials (access points, wifi interface) but also of knowledge in propagation of electromagnetic waves which is the support of the transmission of data. The teaching of this technology requires practical works which must make it possible for the student to implement this knowledge. This article presents the various means of calculations which we implemented within the framework of practical works to allow the student to visualize and thus to better control the phenomena of propagation existing in a WiFI network.
