Tech innovators showcase Meshtastic's off-grid communication system at Hamfest

The Bonner County Civil Defense Resilience Team showcased an innovative communication tool, Meshtastic, during a recent preparedness training session on April 27, 2025. This technology leverages mesh networking to facilitate off-grid communication, making it a vital resource for emergency situations.

Meshtastic operates using LoRa (Long Range) technology, which allows devices to send messages over significant distances with minimal power. Presenters highlighted its ability to transmit messages up to 20 miles in open terrain, with some users reporting successful communications over 100 miles under optimal conditions. This capability is particularly beneficial for areas lacking traditional internet or cellular service.

The training included a hands-on demonstration of various Meshtastic devices, which can connect via Bluetooth to smartphones or operate independently. Participants were encouraged to explore the devices and experience the technology firsthand. The presenters emphasized the importance of asynchronous communication, allowing users to send and receive messages without needing to be online simultaneously, a feature that sets Meshtastic apart from conventional ham radio systems.

Additionally, the session covered the technical aspects of the technology, including its use of the unlicensed ISM band, which allows for encryption and privacy in communications. This aspect is crucial for users who prioritize secure messaging in sensitive situations.

The event not only educated attendees about the practical applications of Meshtastic but also fostered community engagement in emergency preparedness. As Bonner County continues to enhance its resilience against disasters, tools like Meshtastic are poised to play a significant role in ensuring effective communication when it matters most.
