Simulated Propagation Properties for Future Outdoor sub-THz Networks

The sub-THz spectrum is today one of the most promising technologies to provide large network capacities beyond the 5G era. The modelling of the propagation channel is needed for research and test, but the channel understanding is still limited. One of the key challenges at these high frequencies is the large propagation loss, in particular the impact of vegetation on outdoor links. In this paper, a ray-based tool validated at millimeter-wave frequencies is used to analyze and characterize the outdoor propagation channel at 150 GHz. Different environments like urban canyon, residential and a wide main street are considered and accurately modeled with LiDAR data, in order to assess the propagation properties for several outdoor antenna configurations: mesh backhaul, Fixed Wireless Access (FWA) and mobiles access. Such simulation studies in conjunction with measurements can lead to better channel understanding. Interesting perspectives on the validation of subTHz use cases and deployment strategies can be formed.
