There are times when cellular services just stop working. Whether it’s because we’re off the grid in the wilderness, or in the middle of a natural disaster, our lives have become dependant on being able to communicate with one another and when outages happen, we tend to freak out. GoTenna is a device that connects to a smartphone and allows it to communicate with another GoTenna-connected phone, even when you have no service. It uses low-frequency radio waves to transmit low-density data over long distances, which in ideal conditions can give you a 50.5 miles range. You can send texts to one another, or share locations so you can find your loved ones even when everyone around you is desperately trying to use their cellphones to do the same. You can even send encrypted messages to one another which aren’t stored anywhere.
It’s a powerful device with tons of features and we feel it completely warrants the $150/pair asking price. That’s the pre-order rate, which is expected to go up to $300 for a pair once it fully hits retail distribution. It ships in late Fall 2014.
