In this paper 26GHz propagation in outdoor urban environment is investigated using path-loss measurements and ray-tracing simulation. The impact of advanced implementations such as diffuse scattering and vegetation attenuation is verified versus measurements in an outdoor scenario. The results show that the contribution from non-specular components in nonline-of-sight conditions is much more important than expected to achieve a good prediction accuracy at this frequency band. Moreover, vegetation attenuation is also very relevant and can be modeled using a simple, specific attenuation formula. Despite some deficiencies in the input database, the prediction accuracy is good and simulations are generally able to track the measurements behavior.

Abstract

In this paper 26GHz propagation in outdoor urban environment is investigated using path-loss measurements and ray-tracing simulation. The impact of advanced implementations such as diffuse scattering and vegetation attenuation is verified versus measurements in an outdoor scenario. The results show that the contribution from non-specular components in nonline-of-sight conditions is much more important than expected to achieve a good prediction accuracy at this frequency band. Moreover, vegetation attenuation is also very relevant and can be modeled using a simple, specific attenuation formula. Despite some deficiencies in the input database, the prediction accuracy is good and simulations are generally able to track the measurements behavior.
