Caractérisation et modélisation de la propagation des ondes électromagnétiques à 60 GHz à l'intérieur des bâtiments

Abstract : Wireless telecommunications have been driven by a sustained interest for more than a decade. Compared to wired telecommunications, wireless technologies make it possible to simplify the networks infrastructures, to increase the mobility, and finally to make the use more flexible for everybody.

The actual challenge for wireless telecommunications is to ensure a growth of the transmission rates. Several techniques are still under study, among which one can find the increase of the working frequency toward the millimeter waves spectrum. The thesis lies within ther framework of this approach and presents the results of the characterization and the statistical modelization of the 60 GHz indoor propagation channel. This work is based on several measurement campaigns, mainly performed in residential environments.

The main results underline the shadowing effect caused by the human activity, and the difficulty of the propagation between rooms of a building. Last, the measurements reveal that an angular diversity schem can be an interesting solution to overcome these difficulties. Moreover, a sptio-temporal model and a time-variant model of the channel are described, based on the statistical properties of the channel characteristics.
