Aster is a high-performance propagation model for Atoll that supports macro, micro, and small cell urban propagation scenarios.

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

Scope

  • Support for all radio access technologies (GSM, UMTS, LTE, …)
  • Support for frequencies ranging from 150 MHz to 5 GHz
  • 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

Configuration & Calibration

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