A ray tracing prediction tool with advanced implementations such as diffuse scattering and vegetation attenuation, is validated vs. mm-Wave frequencies measurements in urban environment at 26GHz and 38GHz. This is one of the first investigations at these frequencies in outdoor scenario. Simulations are compared with measurements in terms of path loss in two different urban scenarios. Results show that the contribution from non-specular components in non-line-of-sight conditions is determinant to achieve a good prediction accuracy at these frequencies and that the excess loss due to vegetation cannot be neglected. To sum up, the prediction accuracy is good and simulations are generally able to track the measurements behavior.

Abstract
A ray tracing prediction tool with advanced implementations such as diffuse scattering and vegetation attenuation, is validated vs. mm-Wave frequencies measurements in urban environment at 26GHz and 38GHz. This is one of the first investigations at these frequencies in outdoor scenario. Simulations are compared with measurements in terms of path loss in two different urban scenarios. Results show that the contribution from non-specular components in non-line-of-sight conditions is determinant to achieve a good prediction accuracy at these frequencies and that the excess loss due to vegetation cannot be neglected. To sum up, the prediction accuracy is good and simulations are generally able to track the measurements behavior.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
