Synapse is a high-performance propagation model developed by Orange Labs.

Capping several years of research in domains such as: propagation, modeling, optimization and algorithms, the Synapse propagation model is able to automatically adapt itself to all engineering (micro, mini, small, and macro cells), to all environments (dense urban, urban, suburban, mountainous, maritime, and open), and to all systems (DVB-H, GSM, GPRS, EDGE, UMTS, WiFi, WiMAX, LTE and 5G) in a frequency range starting from 200 MHz to 40 GHz.

Relying on very realistic modeling of the channel, it achieves the synergy of the three physical elementary contributions: diffraction in the vertical plane, guided propagation in the horizontal plane, and reflection on the relief.

In this way, the calculation of the signal level at each point is calculated by combining the components that occur in each one:

•The profile component

•Morphology data

•Facet data

•Graph data

•The multipath component
