If you’re deep in the Amazon jungle, in a hurricane, or traveling too far from a cell phone tower, your text message won’t go through. (Good luck dealing with the giant Anaconda.) A new device called “goTenna” fixes that by using radio signals.
The device pairs with your cell phone to let you send a text message even when you don’t have Wi-Fi or a cellular signal. You type on your phone as you normally would, and the message goes out as a radio signal that can be received up to 50 miles away. (Fifty-one miles away you’re in big trouble.)
The product should be out this Fall, when a pair of goTennas, one for you and one for the person you want to talk to, will sell for $300. Those who pre-order can get a pair for $150. (You should know that low-power radio transmissions can be affected by a number of factors, such as intervening hills, buildings and warm air layers.)
