The application scenarios and requirements are more diverse in the fifth-generation (5G) era
than before. In order to successfully support the system design and deployment, accurate …

This paper presents 28 GHz wideband propagation channel characteristics for millimeter
wave (mmWave) urban cellular communication systems. The mmWave spectrum is …

The digital transformation within the automotive industry is accelerating towards an era
dominated by autonomous vehicles, with vehicle-to-everything (V2X) communications being …

The World Radiocommunication Conference 2015 (WRC-15) identified a number of
frequency bands between 24 and 86 GHz as candidate frequencies for future cellular …

Channel simulators capitalizing on the ray-tracing (RT) principle are widely used in wireless
communications for generating realistic channel data. By combining the RT algorithm for the …

Millimeter wave technology will be dominating the fifth-generation networks due to the clear
advantage of higher frequency bands and hence wider spectrum. In this paper, the indoor …

This paper considers a fundamental issue of path loss (PL) modeling in urban micro cell
(UMi) environments, namely the spatial consistency of the model as the mobile station …

We consider a dense urban cellular network where the base stations (BSs) are stacked
vertically as well as extending infinitely in the horizontal plane, resulting in a greater than …

In this paper, the channel characteristics and cell coverage of the 28 GHz millimeter wave
(mmWave) band outdoors are investigated by developing an efficient 3-D ray-tracing …

In this paper, we analyze the radio channel characteristics at mmWave frequencies for 5G
cellular communications in urban scenarios. 3D-ray tracing simulations in the downtown …
