Homemade Faraday Cage

Take some aluminum blankets from a dollar store and some twine. Tape the two or more aluminum blankets together and drape overtop of twine that has been suspended from wall to wall overtop of your bed. Then apply a barrier at the head, foot, and, if you would like, underneath the bed for maximum coverage. Alternatively, you can also apply barrier(s) to the walls and windows. The goal is to try and block as many frequencies as possible. Remember that cordless phones and cell phones also generate wireless frequencies so having them in the bedroom will defeat the purpose of setting up a barrier in the room.
