Fifth-generation (5G) cellular networks will almost certainly operate in the high-bandwidth,
underutilized millimeter-wave (mmWave) frequency spectrum, which offers the potentiality of …

Recent times have seen a significant increase in capacity demands resulting in small cells
deployment. The application of standard radio channel models is not straightforward in such …

In order to support the development of channel models for higher frequency bands, multiple
urban microcellular measurement campaigns have been carried out in Berlin, Germany, at …

In recent years, ray-tracing simulation is widely adopted to model outdoor radio propagation.
However, existing studies have not focused on the blockage effect of roadside trees. In this …

The author presents the numerical and empirical analysis of the recently introduced by the
author and now improved fast ray-tracing algorithm for calculation of stochastic …

Radio waves at higher frequencies in the current and future generations of radio networks
are more sensitive to details in the environment as they propagate. Previous measurements …

Recently, to cope with rapidly increasing data traffic, ITU-R established the concept of 5th
generation mobile communication (5G) and defined requirements. Additionally, the 3GPP …

This thesis presents measurements, characterizations and modeling approaches of the
outdoor millimeter-wave access channel. More specifically, in this thesis I address an …
