We study the detectability of the emission associated with the AGN dusty structure at submillimeter wavelengths using ALMA, in a theoretical and observational way. Theoretically, we use the Clumpy models from Nenkova et al., together with the MIR to X-ray and radio fundamental plane scaling relations. We find that it is more likely to detect bigger and denser dusty tori at the highest ALMA frequency (666 GHz/450 mu m). We also find that with 1 hr at 353 GHz/850 mu m and 10 hr at 666 GHz/450 mu m we can detect, with a high detection limit, a 1 mJy torus (characteristic of bright AGNs).
