Meshtastic networks use LoRa technology operating in license-free ISM bands, enabling devices to communicate over several kilometers with minimal power consumption.

LoRa radios transmit at low power but over long distances, often several kilometers in open areas, allowing Meshtastic nodes to maintain connections without frequent battery replacements. Their operation in unlicensed ISM radio bands means users avoid regulatory hurdles typical of other communication technologies. This combination of range, power efficiency, and open accessibility makes Meshtastic especially suitable for outdoor activities and emergency communications.
