TL;DR: In this article, an extensive review of propagation characteristics and challenges related to the use of millimeter wave (mm-wave) in future wireless systems is presented, and the need for new multidimensional models and measurements is identified.

TL;DR: Directional, dual-link, quad-polarized 60GHz channel measurements have been carried out in a small-office environment to study the directional properties of the channel in view of future multi-gigabit system adopting beam-forming or macro-diversity solutions.

TL;DR: In this article, the authors compare the sub-6 GHz with the mm-wave channel at 30 GHz and 60 GHz in street canyon scenarios using the same measurement equipment in Germany and Japan.

TL;DR: A novel hybrid architecture for mm- wave beam-forming is described, which addresses the mm-wave specific propagation channel characteristics that are identified in recent measurement campaigns and leverages baseband processing both in analog and digital domain.

TL;DR: Direction small scale fading measurements are used to extract the fading statistics of the received signal magnitude and the parameters of the underlying stochastic model with a special focus on the number of sinusoids/scatterers and their weights.
