In contrary to its name the model only considers floors/ceilings, as including walls demands for costly intersection tests to determine all walls along the signal's line-of-sight.
|

While including walls within the model would increase the accuracy of the model's prediction \cite{PropagationModelling, radar},
|

for many use-cases it is sufficient to just consider floors/ceilings,

to reduce the performance impact when being used on smartphones.
