goTenna Mesh
So what’s a goTenna Mesh? It’s a portable battery-powered antenna that’s capable of forming an ad-hoc wireless mesh network with other goTenna Mesh units in-range. That is to say, they don’t connect to the internet, wi-fi, or the cellular network -- just to each other.

Unlike many goTenna users, I'm rarely off the beaten path deep in the woods, or on an ocean cruise.
