Sending Messages Off-grid

Posted November 09, 2016 12:00 AM by Engineering360 eNewsletter

In the aftermath of storms like Hurricane Matthew, interrupted cellular connectivity can leave consumers cut off from communication. A new consumer network, goTenna Mesh, is an off-grid, long-range mesh network. Using point-to-point functionality, the product developers claim that the network increases range and that all communication is encrypted.

No thanks. Point to point is the problem here. You can only talk to another goTenna device, no 911, GPS or other functions.

Like a two way radio, but that's about it, and it's battery powered so in a true disaster both your range and useful life are limited.

I can buy 5 watt multi-freq. commercial radios for $60.00 USD.

And even on the farm in Ark. I have cell coverage.

Great idea for camping/hiking, but not for emergencies.

Before the advent of cell phones, those in the rescue industry used 2 way radio, like am ( CB ) & FM transceivers.

The best thing about these communication devices is that you don't need to pay a monthly fee, your not tied to a " Grid " and there is no such thing as a dropped call or being " out of the coverage area " .

Recently the new system one of our local agencies was using crashed. Luckily they still had two-way radios in their trucks and were able to keep communicating.

Maybe a telegraph is much better than that.
