If Modern Communication Systems Are Down, Which is the Most Secure Method of Communicating?
- Walkie Talkies
- Smoke Signals
- Morse Code
The Beartooth is a unique device that works with your smartphone — even when the cell towers are down. Communication is encrypted, so that only you and another Beartooth user can hear or see what you say. You can learn more about the Beartooth by reading our Beartooth product review.
Smoke signals are among one of the oldest forms of communication across limited distances. If you want to get someone’s attention, they’re great for announcing your presence. However, they are only secure on a limited basis if you have worked out signals with someone else who might see them. They have the drawback of being highly visible, so keep that in mind before lighting one. Not everyone is a friendly traveler in these situations.
Walkie talkies work well, but most don’t provide encryption, so anyone who is on the same channel as you are can hear what you are saying. You can use morse code with them, but again, it isn’t secure because anyone who knows the code knows what you’re saying.
