Aster is a high-performance propagation model for Atoll that supports macro, micro, and small cell urban propagation scenarios. Aster also includes a dedicated mmWave propagation model for 5G frequencies above 6GHz.

Aster is based on advanced ray-tracing propagation techniques and combines high accuracy with superior calculation speed.


Aster Propagation Model

  • Support for all radio access technologies (5G NR, LTE, UMTS, GSM, …)
  • Support for frequencies below and above 6GHz including mmWave
  • Support for all types of cells with pre-configured and user-defined parameters: macro, micro, and small cells
  • Support for all types of propagation environments: rural, suburban, urban, dense urban

Propagation Modelling

  • Vertical diffraction over roof-tops
  • Horizontal diffraction/reflection based on ray-launching
  • Ray-tracing calculation on raster data as well as on vector building data

High-Frequency Propagation Modelling

  • Vegetation: diffraction & through loss
  • Atmospheric absorption
  • Rain attenuation
  • LoS propagation at different heights
  • Diffraction, specular reflections

Configuration & Calibration

  • Support of multi-threading and distributed computing
  • Automatic calibration using CW measurements
