How To Communicate When The World Goes Silent

So how would you communicate with your family or get help if communications go down?

So if you found yourself in the middle of a wide-scale disaster such as a hurricane or other catastrophe and you had no government coming to help for a while, how would you communicate with your family or others? What if the power grid went down?

You won’t be able to rely on your cell phone. There are alternatives, however.

I’ll go over the basics of some emergency communication methods but if you want more detail, check out Personal Emergency Communications: Staying in Touch Post-Disaster: Technology, Gear and Planning.

Short-term emergencies have shown the limitations of using cell phones to coordinate with each other. Even if the towers are operational, they can’t handle the added traffic of millions of people trying to get a hold of loved ones – or help. Ever had trouble calling your mother on the morning of Mother’s Day?

During many recent events, cell phone service wasn’t an option for many for days. The system became seriously overloaded on 9/11 so calls wouldn’t go through, 70% of the towers went down during Katrina and were down for days, and most areas haven’t been adequately improved across the US.

These won’t be isolated events. Don’t think that because you live in a large metropolitan area that you’re safer. A quick look at some of the things that went on during Hurricane Sandy in NY will show that the government has a lot to deal with in addition to just trying to get your cell phone service back up so even though that was a pretty short-term event, it caused a lot of problems.

Here are just a few issues that would affect you being able to pull out your iPhone to call up people:

• Cell phone communication has a lot of vulnerabilities that make it a poor solution for widespread or long-term emergencies.
• Heavy winds or flooding can disrupt the cables between towers such as during Hurricane Sandy.
• Cell towers require AC power to operate so if they don’t have an automatic backup system, they stop. Keep in mind that a lot of towers are just glorified antennas on the tops of buildings or mountains and backup power, such as an emergency generator, is a very short-term solution. Generators require fuel and that fuel has to be replenished quite often. In a lot of cases, the only backup power available is a bank of batteries that stop charging when the main power system stops.
• Backhaul systems (essentially the system that connects and/or allows overflow from outer systems to the core, often including other carriers) aren’t always reliable. A lot of this system is wired but has been expanded to microwave and other systems.
• Most cell phones will only stay charged for a day or three. If you don’t have local power to keep it up, when the system does come back up, you won’t be able to talk to it.
• Cell phones require satellites, which are vulnerable to hackers, physical attack, or solar storms.

Now don’t get me wrong, for day-to-day emergencies, such as getting a flat tire, a cell phone usually works pretty well. It’s just a crappy solution for big emergencies. They’ll be pretty useless if the national grid goes down due to a cyber attack, EMP or CME, which is actually a lot more likely than you might think.

One cool idea that’s coming out is the goTenna cell phone radio antenna system. Your cell phone connects to it via Bluetooth and an app, and the signal is sent and received through an encrypted radio signal. How awesome is that? It won’t be able to reach to the other side of a city but you should be able to locate your family if they’re in the area and maybe even communicate with others if they have the system.

So if you can’t rely on cell phone service, what other options do you have?
