What Will Be Best Form of Communication If the Grid Goes Down?

cb radio wikimediaWhat is the lowest common denominator of our civilization, or any civilization for that matter? By that I mean, what is the one thing no society can go without? Is it water and sanitation? Fuel and transportation? Food and electricity?

I would argue that absolutely nothing we have is possible without our ability to communicate. A society’s sophistication is directly proportional to the ability of its citizens to communicate with each other. Members of a primitive, nomadic society may only be able to speak to each other in person, whereas an advanced industrial society has telephones, radios, and the internet. And don’t think for a moment that high tech societies create these devices. On the contrary, these devices create high tech societies.

So we should ask ourselves what the most useful forms of communication would be, should the grid ever go down permanently; not only to keep in touch with other survivors, but to help rebuild society after the cataclysm has passed. Without some of these critical tools, we’re only prepping to survive, not to thrive.

Cell Phones/Computers

At first glace, there is little potential for these devices when the grid goes down. Without the multitude of servers that are scattered around the globe and the electricity that feeds them, our computers are nothing more than bulky hard drives. Cell phones might still work for a little while since some cell towers have backup batteries and solar panels, but their usefulness might be short lived.

However, don’t be too quick to scoff at the prepping potential of these devices. Computers might still be useful for communicating in some cases. It’s fairly easy to create a local wifi network (aka ad hoc network) between computers that are within range of each other. This would allow people living on the same street or in the same apartment building to talk to each other, provided they can generate their own electricity.

The better solution would be to create a local network with cell phones that isn’t reliant on any infrastructure. Their energy demands are far less than other computers, their range is longer than wifi, and they are of course, mobile. The technology for creating peer to peer networks between cell phones has existed for some time now, but unfortunately it has yet to be sold to the public. Companies like Terranet have been perfecting it over the past few years, and they estimate that about 30% of cell phones will be capable of making these networks with a simple software change. So right now, cell phones will be pretty much useless when the grid goes down, but that may change before the end of the decade.

Ham Radio

When most preppers think of communications, ham radios usually come to mind, and for good reason. They can communicate to other radios over hundreds of miles, and they may be the only form of very long distance communication when all else fails. Unfortunately, they wouldn’t be very useful for the average person.

They use a lot of electricity, the equipment can be pretty expensive, and only about 700,000 Americans are licensed operators. Still, if even a fraction of them are up and running after a major disaster, they will play a crucial role in the relief effort. Due to their limited numbers and the amount of resources that are required to keep them running, you won’t see them being used for casual conversation, but you will see them used by communities for conducting commerce and coordinating reconstruction efforts.

CB Radio/Walkie Talkie

I suspect that CB Radio’s and Walkie Talkies will be the main form of communication for the average person, and they are the best candidates for filling the gap that cell phones and internet providers would leave behind. If anything, CB radios were our parents version of the internet. They were affordable and accessible, you had to learn the lingo to use them, they allowed you to communicate anonymously, and much like the internet, they were used to skirt the law from time to time.

There are millions of CB radios lying around, and many of them are still being used by truckers today, so they will be available to many of the survivors. More importantly, they don’t use too much electricity, they’re more user friendly than ham radios, and some of them are portable. Depending on the conditions you’re using them in, their range can extend anywhere from 1 to 25 miles.

As for walkie talkies, I don’t have to tell you how useful they could be. Much like the wifi network I spoke of earlier, these will be pretty handy for staying in touch with your neighbors. Together, CB radios and walkie talkies will be most common form communication after a disaster.


If the grid is down long enough, eventually some enterprising citizens would start to provide courier services. Whether it’s by foot or by bicycle, they will fill an important niche that other items on this list can’t provide, and that is a secure form of communication. If you had to send a message to someone who lives out of the range of your radio or wifi network, and you needed that message to remain a secret, writing that message down and sending someone out to deliver it by hand would be the only way to do it. Wifi just doesn’t have the range, and radios are too easy to listen in on.


So how do you plan on keeping in touch with your friends and relatives after a cataclysmic event? Are their any other methods or technologies that should have been included in this list?

    Nice, timly article. I am training with a group of others on the benefits of the hand-held HAM. Studying for the Tech license. The little BoeFeng 5 is the beast, and will do HAM and GRMS (walkie-talkie).

    • The BoeFeng will be confiscated by anyone who knows that it isn’t type accepted by the FCC for GMRS use. How will you program it without an operational computer?

      • Bill Kelly

        You can program it by direct entry on the keypad. And, who is going to confiscate it? In a SHTF situation, who gives a rats a$$ about the FCC? I think they will be looking for all the guys with the license and their name in the feds data base. They will NOT want you to communicate with each other. Get real.

      • Licenses are academic during a national emergency, and TPTB will confiscate whatever they want, whenever they want, regardless of whether there is a law to allow or prohibit it, or not.
        Looking in a database won’t secure anything any more than feeling up granny in a TSA checkpoint. You said it yourself, they won’t want us to communicate with each other. Why would they let YOU keep your crappy BoeFeng if it can communicate with anyone else? By crappy, I mean just that. The BoeFeng is a expensive crystal set with fancy lights. There is a reason why they are inexpensive. You are the one who needs to come out of your fantasy world and get real.

      • Bill Kelly

        It works just as well as my Icom and Kenwood, you get real a$$hole

      • Bill Kelly

        And it’s Baofeng moron. And the database contains address’s and city’s and states. And dont forget call letters with your name attached. And they will only take what you let them take. You must be a spineless democrap liberal

      • You are one of the hundreds of hams like yourself that constitute the reason why I don’t want to become one. I get really tired of hearing you and your sorry bastard buddies tuning up out of band on top of shortwave stations I’m trying to copy. All of that data is available online, no need to buy a piece of Chinese junk. There are no call letters attached to my name, just a registration number for my GROL. How you can discern my political position from my refusal to share your technocrapical concepts is best left to the ouija board you probably use for tech support.

  • Speaking as the holder of an FCC General Radiotelephone Operator License, a Commercial Drivers License, and an original (if now unnecessary and obsolete) Citizen Band radio license, I can say that ALL non-portable CB radios operate on 12 VDC, like the ones in the trucks. Most amateur radio equipment is made, not by its user, as the original premise called for, but by the same factories that make all of the other state of the art electronics. While working as a broadcast radio engineer, I encountered several “hams” who knew more about talking around the world than they did about across town or counties.
    Cellphones would be useless without cell towers, because they are nothing but computer terminals under the complete control of the networks that use the towers. There are some systems (goTenna) that use the Bluetooth capability of the smartphone to turn it into a low grade VHF handie-talkie (a walkie-talkie is something soldiers carried on their backs, not in their hands) which (in the case of goTenna) can only do text, and voice is the best in an emergency. IMO, if you want to be in touch after TSHTF, your best bet would be a CB or FRS/GMRS handheld, because they are cheap and plentiful. If you want something with text and/or GPS capability, the pricey but handy Rino from Garmin would be my choice.
    To call couriers secure, they’d have to be invisible to be immune to being physically interdicted in the mobs that will inhabit the streets.

  • Hams have this habit of disappearing when they are asked to be VEs. Why is that, when we have such a desperate need for Elmers instead of Houdindis?

  • Stu Pendisdick

    “Ham Radio…They use a lot of electricity, the equipment can be pretty expensive, and only about 700,000 Americans are licensed operators….”

    So much misinformation in such a short few words.

    I suggest the author visit a “field day” exercise and see what off-grid communications really looks like.

    As to the costs involved, perhaps the author needs to visit a Hamfest in his area, where one can buy very good equipment second hand at very reasonable prices.

    Lastly, if it all goes to hell, who is really going to give a damn about needing a license?

    “Badges? We don’t need no stinking badges!”

    • John Tahoe

      Makes sense to know as much as possible. The Boefang with ear and speaker for mobility @ $50 is a no brainer. After the SHTF I don’t want any “friends” to “help” me for the first few months; true colors will show in a couple of months then alliances can be formed. People you grew up with might turn on you; the person you least expect may be a hero. COMSEC

    You forgot one, THE PONY EXPRESS!

  • ron17571

    2 meter hand held.Using rechargable batterys.Around 50.00 bucks. Repeaters use solar and should stay up. Much better than a CB or a GMRS type radio. MURS is another to check out.

    • Bill Leaming

      I have a both a 2m and GMRS repeater running, with battery and solar backup power. Between the two I provide good communications over a 90 mile radius.

  • Again, in an emergency, any unused spectrum can be used for emergency traffic.

    The article forgot to mention a transmission of thought.
    I have been thinking about this since I was 13 , and saw a movie about the” end of world”, where just a few people are left , trying to rebuild.

    It sounds hoaxy, but it is not at all …one can actually measure the waves of thought activity in the brain. So as one INTENDS it to go toward outside, and DIRECTS it toward a person of intent, it can be received.
    I was in school later, and part of our training was scientific experiment, documented in writing, on transmitting thought. Highly recommend it to you. Choose a buddy, choose a time to calm down, sit quietly and breathe, while your buddy in another location sits down, closes their eyes as well, focusing on breath. After about 5 minutes, focus on a color – you can use a color paper, color sticky note, solid color T-shirt, or such. Your buddy sitting quietly is to think about you, and write down any thought the buddy may have about color.
    Later compare notes. If you succeeded, pat yourself on the shoulder. If not, pat yourself on the shoulder as well for doing this, and do more experiments. We did not learn our ABC on the very first attempt either. In my class success the first time was about 70%, and we gone all the way up to 100% after a few attempts. – After you master color, you might focus on smell – like ammonia, lemon, orange, etc. Some very simple , distinct smell. Eventually you will be able to get what someone is communicating to you. Like – call mom. Go to the post office. In our small town that is where we all seem to meet when thinking about contacting someone. Simple thoughts, like seeing a traffic jam – do I stay, or should I take this exit ? – All of those, when confirmed helpful keep you trained in mind to mind communication. Many countries actually did scientific research on this subject. Mind to mind is real. Once you practice, it might save your vacation, or perhaps your life.
