More about Blackout Comms:
Securely and privately send encrypted text messages and location data with others in your local area, even when no services are available! Blackout Comms is designed to help you communicate in the absence of internet or cell service. In addition to text communication, it also allows you to securely share GPS location between trusted individuals and links in your private cluster. Blackout Comms uses LoRa frequencies, advanced mesh algorithms, encryption, and other techniques to accomplish this. 

There is no service or internet required, these things communicate directly  (and via mesh) through the air using encrypted RF signals across multiple LoRa frequencies.

You do not need to download any app, figure out technical settings, or add any additional components to make these work. Simply turn them on!

These devices allow local, secure, text communication, location awareness, and location sharing, all with zero need internet, cell towers, cell service, mobile phones/apps, WiFi, or any centralized/grid-based system. When devices are in range with one another and a message is sent, it is similar to instant messaging (happens in seconds). When devices are out of range, it's a little more like email, and the message is delivered as soon as a mesh path becomes available.

The range you can expect depends on many factors, mainly line-of-sight and where your devices are located. When devices are out of range, messages are securely cached for up to 24 hours until they can be delivered.

All communications happen over LoRa frequencies, and utilize strong encryption and digital signatures. Your messages are stored encrypted on the Heltec's flash memory. These devices charge from a USB-C port.
