Claim 12:
13. A system for determining environmental-specific propagation characteristics of a radio frequency (RF) signal, the system comprising:
a memory storing instructions; and
at least one processor coupled to the memory, the at least one processor configured to access the instructions from the memory to perform operations comprising:
receiving a plurality of first propagation characteristics of the RF signal;
determining a feature vector based on the plurality of first propagation characteristics;
inputting the feature vector to a machine-learning meta-model;
executing the machine-learning meta-model to select a particular physics-specific model from a plurality of physics-specific models, wherein each of the physics-specific models is for a different RF signal propagation environment;
inputting the feature vector to the particular physics-specific model; and
executing the particular physics-specific model to output an estimate of one or more second propagation characteristics of the RF signal based on the feature vector.
