How to communicate when you have no cellular coverage?

My name is Randolf. I represent a team of engineers who happen to be outdoor lovers and used to work in Motorola, Honeywell, and the satellite industry. Dangerous situations we each experienced in the wilderness brought us together, and we came to realize that there is a serious need for better off-grid communication.

Walkie-talkies are what we commonly use when there is no cell coverage. However they have no GPS. In case of an emergency, we cannot find the exact location. Satellite communication, such as DeLorme inReach, seems ideal, except that they are quite expensive, and further charge usage fees. Besides, both options are pretty heavy and bulky that we have to make a painful trade-off between safety and portability.

We feel extremely astonishing that we have to rely on some technologies of half a century ago like walkie-talkie and satellite communication, while nowadays’ technology can do far better. Based on the latest Internet of Things tech, we have invented Sonnet. It combines satellite communication’ functionality with walkies-talkies’ affordability, in addition to being more portable. Without relying on cell towers, Sonnet powers up to 10km communication to:
- send text and voice messages (privately or in a group);
- send image data, and files;
- share, mark and track GPS locations;
- set up your own off-grind communication network;

When there is no coverage, Sonnet allows us to always communicate with each other no matter how harsh the conditions are. This can literally save our lives in case of an emergency. Multimedia and GPS can also improve our communication accuracy, and take group coordination to the next level.

We will sell Sonnet at $89 per pair. And it is one time purchase for the hardware.

We would be very grateful for any feedback you guys might have!

Thanks for viewing,
Randolf

Is there a charge for service to be able to communicate with these devices after purchasing them?
