The Sonnet device is an Off-Grid Mobile Network (via Kickstarter) that allows you to setup a private network that you can access with a web browser. You can use it to send texts, pictures, voice message, GPS information, and even SOS requests to other users on the network.

This is really awesome for groups going hiking or camping out where cell access is spotty at best. It’s also pretty handy for conferences or conventions where the existing network can be overloaded.

If this all sounds familiar, it’s probably because there are other devices out there that allow you to setup your own Off-Grid Mobile Network. For example, the GoTenna.

The Sonnet is different in that there are no special apps required. All you need is a device with a web browser. That means it will work with a laptop or tablet just as well as your phone. All of the functionality is hosted by the Sonnet units. Oh, also, Sonnet is about half the price.

The Sonnet is capable of transmitting up to 3 miles (5km) between units. However, using a built-in a mesh networking protocol,  effective range can be much larger. This allows users to send data to recipients who are out of point-to-point range by automagically relaying data through other users in the area.

All communications are encrypted with AES. In addition, Wi-Fi connections between Sonnet and your smartphones are protected with WPA/WPA2.

Sonnet not only allows you to stay connected with your friends and family. In the case of emergencies, you can also call out to random strangers for help. The Sonnet web app comes with a panic button. Long-press the button for 5 seconds will activate the SOS mode, broadcasting your current GPS location and your distress message to all Sonnet users in range.

Sonnet even comes with a USB port so you can charge your smartphone with it. Sonnet is equipped with a 4000 mAh battery capacity, which can fully charge most smartphones on the market at least once.

The Kickstarter is already fully-funded and there is over a month to go as I write this. If you back the project, you should get your pair of Sonnet devices by November.

So, if you like to be off-grid or just want your own, private, grid for your friends, the Sonnet is probably something you need.
