Your phone is dependent on the mobile network, and they can't keep you connected when the mobile network is unavailable or unreliable, such as when you are:

• Exploring the backcountry: network is unavailable or very sparse coverage
• Traveling abroad: network unreliable or very expensive to use
• Attending crowded events: network slow and congested with too many users
• Encountering a natural disaster: network service disrupted or completely destroyed

On the other hand, walkie-talkies work anywhere. However, they are:

• Bulky and cumbersome: some walkie-talkies literally feel like bricks that you carry around
• Complex and unintuitive: A lot of tuning and setup require before you can use it
• Very low-quality audio only: no text, no images, just bad audio, which often leads to miscommunication

Sonnet is an Off-the-Grid communication device that lets you use your smartphone as a super advanced walkie-talkie that can send:

Even when you have no cellular coverage and no Internet access!

Sonnet brings the long-range wireless communication of the walkie-talkie to the smartphone. It connects to your smartphone via Wi-Fi, and it will relay any data sent from your phone to other Sonnet devices via the long-range radio wave. This completely removes your smartphones’ dependency on cellular grid and other network infrastructure, and allows it to be used even when you have no cellular connectivity or internet access.

Yup, that's it!

There's no frequency to tune and no channel to set. Just connect and start chatting! Use the Sonnet App in the same way as any other instant messengers to send:

• One-on-one private messages
• Private group messages
• Public messages to any Sonnet users in range (yes, you can block spammers)

Sonnet App runs directly within your smartphone's browser so you don't need to download or install any app!

Sonnet is completely off-the-grid and operates independently of any network infrastructure. This means that Sonnet will let you stay in touch with your friends and teammates no matter where you are.

The typical point-to-point range between two Sonnet devices is 5 km (approximately 3 miles). This range can be up to 15 km (9 miles) if there is line-of-sight, such as when the sender and receiver are on top of two mountains.

In addition, Sonnet comes with a SMA connector, so you can connect your own directional antenna to increase the point-to-point range even further!

Sonnet's mesh network dramatically increases the effective range beyond point-to-point range by relaying data through other deices. With Sonnet, data can be relayed up to 16 times to achieve a maximum range of 80 km (50 miles)!

There is absolutely no subscription fee when you use Sonnet. You can send as many messages as often as you want!

If one device has internet connectivity, then the entire network can share it!

Place Sonnet in a car or base where internet is available, then you can access internet in the backcountry by carrying another Sonnet!

(To be rolled out as a software upgrade in Early 2018).

Offline Maps

The Sonnet App comes with offline maps so you’ll be able to get directions and view points of interest without Internet connection. You can even leave virtual breadcrumbs on the offline map so you can retrace the path back to the origin.

Panic Button / SOS Mode

In the case of emergencies, Sonnet 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.

Charge Your Phone

Sonnet is equipped with a 4000 mAh lithium polymer battery and it comes with a USB port, so you can charge your smartphone with it. Sonnet can fully charge most smartphones on the market.

We take your privacy very, very seriously. As a result, we have taken care to make Sonnet as secure as possible. All communications done with Sonnet are end-to-end encrypted with AES (256-bit). In addition, Wi-Fi connections between Sonnet and your smartphones are protected with WPA/WPA2.

Sonnet features a rugged design that makes it well-suited for outdoor use. It is rated IP66, which means that it is dust tight and water resistant. This allows you to bring the Sonnet with you no matter which adventure you are on.

At Sonnet Labs, we aim to democratize mobile communication with technologies that enable smartphones to communicate without relying on centralized infrastructures. Founded by a group of avid outdoor enthusiasts, we initially built the Sonnet just for ourselves as a way to stay in touch with friends when we are out hiking. We quickly realized that the mission is much greater than that: by making long-range mesh networking technology that is secure, easy-to-use, and accessible to everyone, we can lay the foundation for creating a truly open, decentralized digital communication network, built for and powered by the people.

We are based in Toronto, Canada, and our team comprises of amazing people who have worked in Motorola, Honeywell, and Hai'er.

The Sonnet will be shipped worldwide with tracked shipping. Due to variations in shipping rates across the globe, the tier prices do not include shipping fees. These fees are separately calculated based on your shipping country and will be automatically added when you complete your pledge on Kickstarter.
