You could build such a system into the building material itself. While the law clearly prohibits using a device to actively disrupt a cell-phone signal, there are no rules against passive cell-phone blocking. That means using things like wallpaper or building materials embedded with metal fragments to prevent cell-phone signals from reaching inside or outside the room. Some buildings already have designs that unintentionally block radio signals due to thick concrete walls or a steel skeleton.
