The goTenna allows your cell phone to communicate with other goTennas without the need of cell towers. It's a way to communicate completely off the grid. You simply pair one of the goTennas with your phone via bluetooth install the app and designate who you will want to receive your text message. The signal is sent via long-range radio waves to another goTenna(s). You can expect distances at street level to be about .5-1 mile.
