This talk will focus on a very interesting topic nowadays such as the detectability of the emission associated with the Active Galactic Nuclei (AGN) dusty structure at (sub)mm wavelengths. We hack this issue with a theoretical and observational approach. Theoretically, we investigate this subject using the Clumpy model together with the fundamental plane scaling relations. The latter was included since a no negligible contribution at sub-mm wavelength may still come from AGN radio jets. For the observational approach, we used four prototypical AGN: NGC 1052, NGC 1068, NGC 3516, and IZw1, with cm (JVLA A-configuration), (sub)millimeter (ALMA), and mid-IR (Spitzer) available data. After performing the mid-IR and cm-spectrum fitting separately, we combined and extrapolated both fits to the (sub)mm window. Our observational results are consistent with our theoretical results for which the most accreting source, the QSO IZw1, is our suitable candidate for the detectability of the torus. From our study we strongly recommend that multi-wavelength observations, including high angular resolution centimeter data, is mandatory for the detectability of a torus at the (sub)mm window. This will be a very important subject to be addressed to the upcoming radio facility.
