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

Aster Propagation Model
