A Faraday cage can keep your in contact with the outside world during and after an emergency. A Faraday cage (also called a Faraday box, or Faraday shield) uses a conductive metal, usually aluminum or copper, to reroute electrical charges.


Those living in an urban environment may be most susceptible to grid failures due to electronic terrorism or an EMP.While the above simple Faraday box may not protect electronics from the strongest of electromagnetic pulses, at the very least, it will prevent prying ears and eyes from eavesdropping on you.
Essentially, it is a barrier that neither lets electrical waves in or out.These cages block wireless satellite communications, radio and other electromagnetic waves, and heavy-duty versions can prevent damage to sensitive electronic equipment from lightning strikes to electromagnetic pulses (EMP).
