Wireless communication between humans and data transfer between machines is essential for modern societies. Future communication networks aim at higher data rates to enable novel applications. Therefore, higher radio frequencies are considered for them. Radio propagation models are enablers for research of future systems and testing of communication devices. In this research project we will investigate radio propagation at frequencies above 100 GHz, with emphasis on the multipath characteristics. Radio waves propagate from a transmitter to a receiver via multiple pathways. It is commonly understood that the channel is sparser and more specular at radio frequencies that are above those used by the former network generations. However, how and to what extent, is not well known. The research is performed by developing measurement systems, both equipment and procedures, conducting radio channel measurements, and carrying out channel modelling.
