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.
Scope
- 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
