A new phone accessory allows users to create their own long-range wireless network between two or more phones. The goTenna is a six-inch wand that pairs with a phone via Bluetooth LE. goTennas connect to each other at 151-154 MHz, a frequency low enough to reach up to 50 miles with the 2-watt radio in the goTenna (but more typically, 3-10 miles.) Communication is limited to text messaging and location sharing, via the included app, which is available for both iOS and Android. Messages can be sent an individual, a group, or broadcast to all goTenna users in range. All messages are encrypted. The device is intended for people traveling in remote areas where mobile networks may be unavailable, such as hikers or camping families. The device is dust-tight, water-resistant, and has an integrated nylon strap. It is also useful for large events where the mobile network may become overloaded, such as concerts, festivals, and sports matches. The devices will retail for $300/pair in the fall, but can currently be pre-ordered for half-off, or $150/pair.
