You may never realize if you don’t stray much from civilization, but cellular phones are rather tied to their network infrastructure, namely cell towers. GoTenna Mesh offers an alternative in the form of a compact device that pairs with your smartphone via Bluetooth LE and creates a long-range network of its own. Useful for exploring the backcountry, oversea travels, or in emergency situations (power failures, etc), GoTenna Mesh lets you send private messages, host group chat, and broadcast, with a range of about 3 miles in open areas or one mile in congested terrain. True to its name this device also forms a network mesh, using other GoTenna users as relays to get your messages to the intended, privately. It helps that the diminutive device is also weatherproof and weighs less than two ounces.
