The night wrapped up with a demo by GoTenna, a hardware company offering a portable, fully encrypted, off the grid network. Their new product GoTenna Mesh, announced last week and available on Kickstarter, offers the same personal network but now relayed through other users of the product. While their first generation product couldn’t send messages out of network when not connected to cellular data, if a GoTenna Mesh user is in a three-mile range of another user connected to the regular network their data will be relayed through them. Additionally, the team announced a new open SDK, allowing developers come up with clever uses for the new network. With a full usage battery life of 28 hours, the product is currently deployed in India and Syria by non-profits where field communication is critical and local infrastructure is unreliable.
