How To Communicate When the Grid Goes Down
Our fragile communications infrastructure has been having a hard time lately.
- Nearly 3 million residents of Puerto Rico were left without cellphone service for weeks following Hurricane Irma.
- A cyberattack in Venezuela this August left 7 million phone customers without service.
- Hurricane Katrina knocked out more than 1,000 cellular sites when it hit New Orleans in 2005.
- Superstorm Sandy knocked out a quarter of the wireless networks in 2012.
It doesn't take much to windup offline with no way to talk to family members even only across town. So what can you do to protect you and your family, especially dependents and the elderly?
Step 1: Get a Two-Way Radio
When all else fails there has always been Portable Two-Way Radios to help people stay in touch.
For only $30 you can grab one of the best selling and most popular Ham Radios out there: the Baofeng UV-5RA.
- Talk to other radio users within 1 - 4 miles (depending on your environment) or more with a repeater*.
- You can receive severe weather alerts from the National Oceanic and Atmospheric Association (NOAA) as well as FM radio.
- There is a built-in LED light.
- The battery can function for several days on standby mode and you can easily charge these radios from a backup battery bank and USB cable.
*Important Note: Transmitting on many of the frequencies available with a Baofeng UV-5RA require an FTC issued Technicians class License or higher in the US. Please review the laws pertaining to the proper use of these devices in our comprehensive user guide. Listening without transmitting does not require any licensing.
Step 2: Get the goTenna Mesh
Why? You don't need towers or routers to send text messages, you create your own network with a goTenna and a smart phone.

Step 3: Get a Two-Way Satellite Communicator
Thankfully modern technology has given us a new way to communicate from anywhere in the world to anywhere in the world. There is a satellite network above us which covers nearly every inch of the globe which now enables us to use cheap 2-way devices and phones for communications.
One of the most affordable options is the Garmin InReach Series - you can pick two up for the price of one iPhone. They can be used as stand-alone devices or with a smart phone.
