Incomplete Faraday Cage — Aaronia Mesh / X-Dream
How effective is the shielding material (such as Aaronia Mesh or X-Dream) if it is not practical to form a complete Faraday Cage? For example, if there is a smart meter or a Wi-Fi router from the neighbour on the exterior wall, would a grounded 3 m x 3 m Mesh or X-Dream applied on the interior wall provide some degree of attenuation, or would it be a complete waste of time and money?
