When applying any macroscopic model, e.g. free space,
i- how can we simulate only line-of-sight (LOS) transmission?
ii- how can we apply further loss to NLOS only (reflected) ?
iii-how can we determine the number of multi-path components (MPC-NLOS) to only 5 component or less ?
iv- can we disable penetration, i.e., (no outdoor to indoor transmission) ?
