Definition
LoRa (Long Range) is a radio modulation technique developed by Semtech that enables long-distance wireless data transmission at very low power. It uses a chirp spread spectrum (CSS) encoding scheme in unlicensed sub-GHz frequency bands — typically 915 MHz in North America, 868 MHz in Europe — achieving ranges of several kilometres while drawing milliwatts of power. LoRa is a proprietary physical-layer specification; Semtech licenses it to hardware manufacturers who incorporate it into off-the-shelf radio modules.
Also known as: Long Range radio, LoRa PHY, CSS radio modulation.
LoRa vs. LoRaWAN vs. Meshtastic
LoRa is the radio modulation itself — how bits are encoded onto the radio wave. LoRaWAN is a network protocol built on top of LoRa, maintained by the LoRa Alliance, designed for star-topology IoT sensor networks with centralized gateways. Meshtastic is an open-source firmware that also runs on LoRa hardware but uses a peer-to-peer mesh topology rather than LoRaWAN's hub-and-spoke model — making it more appropriate for resilient off-grid communication between equals, rather than IoT data uplinks to a cloud backend.
Why it matters for sovereignty
LoRa hardware is inexpensive, runs on batteries, and operates in unlicensed spectrum — attributes that align with the same philosophy as open-source mining hardware. A small number of LoRa nodes can create a local communication mesh requiring no carrier agreement, no SIM card, and no monthly fee. D-Central's mesh networking hub covers LoRa-based deployment options for Canadian sovereign operators building infrastructure independent of cellular and internet infrastructure.
