Basically, you pair the goTenna with your phone and use it communicate when you are in a congested area or in one with no signal.
From the Gigaom article:
"It’s an extremely low bandwidth network, so it’s really only useful for send text messages and GPS coordinates, but it’s extremely long-range thanks to the ultra-low-band frequencies 151-154 MHz frequencies goTenna uses. Lower frequencies propagate further and can punch through or wrap around obstacles like trees. To put that in perspective, the lowest-band mobile network in operation today is at 700 MHz, while Wi-Fi starts another 1700 MHz further up the electromagnetic spectrum chart."From the FAQ:
"Is goTenna FCC licensed?
Delivery of goTenna is dependent on FCC approval. At this very moment, goTenna is undergoing FCC testing and we expect to complete this process in a couple of weeks."
