Aster is a high-performance propagation model for Atoll that supports macro, micro, and small cell propagation in urban as well as rural environments. 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.
