| Meshtastic (created by Kevin Hester in February 2020, originally conceived as an outdoor communication solution, later led by Ben Meadors) is a protocol and firmware that runs on LoRa (Long Range) enabled devices that allows users to send messages and share information. It has seen a bump in popularity over the last couple of years due to the barrier of entry (software and hardware) being lowered and the usability being enhanced. | Meshtastic (created by Kevin Hester in February 2020, originally conceived as an outdoor communication solution, later led by Ben Meadors) is a protocol and firmware that runs on LoRa (Long Range) enabled devices that allows users to send messages and share information.

| LoRa is a proprietary spread spectrum modulation technique based on Chirp Spread Spectrum technology developed by Cycleo and acquired by Semtech Corporation that uses frequency modulated pulses sweeping across bandwidth, with data encoded by cyclically shifting chirps. Meshtastic firmware transforms these LoRa radio modules into intelligent mesh networking devices capable of multi-hop message relay and automatic network discovery. | LoRa is a proprietary spread spectrum modulation technique based on Chirp Spread Spectrum technology developed by Cycleo and acquired by Semtech Corporation that uses frequency modulated pulses sweeping across bandwidth, with data encoded by cyclically shifting chirps.

| Entry-level devices range from €17-30 with functionality varying by hardware. Popular options include the Heltec LoRa 32 V3 (€17-20) with ESP32-S3 processor and the LILYGO T-Beam V1.2 (€20-25) featuring built-in GPS capabilities. These basic devices require smartphone or computer pairing for message composition and network management. | Entry-level devices range from €17-30 with functionality varying by hardware.
