Propagation channel modeling at centimeter–and–millimeter–wave frequencies in 5G urban micro–cellular context

Abstract : The advent of bandwidth–demanding mobile applications and services has led to a massive explosion of the network data traffic. In order to alleviate this issue, millimeter–Wave communications systems are a promising technology for future 5G systems thanks to the large amount of bandwidth available in this frequency range. However, in order to take full advantage of this technology, knowledge of the radio propagation channel characteristics in these frequency bands is paramount. Therefore, in this thesis, the objective is to study the frequency–dependence of the propagation channel large scale parameters (LSPs), which describe the main channel characteristics. These LSPs include the building penetration losses, the channel delay spread, the channel azimuth spread and the propagation path–loss. The studies are performed thanks to measurement campaigns conducted in Belfort, in typical 5G deployment scenarios such as outdoor–to–indoor and urban outdoor environments, between 3 and 60 GHz.
