The goTenna is a communication device which pairs wirelessly via Bluetooth-LE with your smartphone, enabling you to text and share your location with other goTenna users without using cell towers, Wi-Fi or satellites.

According to the press release, the hardshell of the goTenna — which is water-resistant, lightweight, and dust-tight — boasts a durable molded nylon and metal construction. In addition, it easily fits into a pocket or attaches to a backpack. It is designed for outdoor use, crowded stadiums, or emergency situations.

“Our mission is two-fold,” said Daniela Perdomo, co-founder and CEO of goTenna. “We want to let people communicate on their own terms whenever and wherever they want and make sure that in times of a true emergency they are able to reach others around them.”

The goTenna offers a detailed mapping system, as well as an app — available for iOS or Android — which enables users to create their own networks and communicate one-on-one, in larger groups, or with anyone in the area, the official statement reads. There is also automatic message retry and message delivery confirmation.

According to, the goTenna — which comes with a rechargeable lithium battery with a 72-hour lifespan during regular use — also offers RSA-1024 encryption and self-destruct messages, as well as a flash memory for thousands of messages.
