Angular power distribution measurements and modelling of outdoor urban environment using ray-tracing at 2 and 18 GHz

To enable the fifth generation of mobile communication (5G), understanding of the expected radio channel is needed. This knowledge will enable modelling of the radio environment for use in network planning and development. Due to this, channel measurements were conducted at 18 GHz and 2 GHz for comparison of angular power distribution. The chosen environment for the measurement is an outdoor urban scenario with a transmitting base-station at rooftop level and a receiver at ground level. The measurements show that the propagation environment becomes more directive at 18 GHz compared to 2 GHz. Additional, simulations using a commercial ray-tracing tool where conducted. This to highlight areas of further development of ray-tracing tools to ensure agreement between simulations and measurements.
