Wifi + Noise

First time metal building buyer. Shopped a contractor to install 30x40x10 for shoppe housing embroidery + screen printing equipment. Will have them do the insulation + metal inside walls and ceiling. Is there going to be internet connectivity issues in this building? What are noise levels to be expected since I am not using drywall which can be sound absorbing to some degree. Southern MD They will do prep, build, concrete. I need to find a reputable electrician. Thoughts?
