Description
LoRa (Long Range radio) is a low-power wide-area radio protocol enabling sensor and communication mesh networks over 5–10 km line-of-sight without GSM, Wi-Fi, or satellite. In a community context, LoRa serves as the long-range backbone of a three-tier mesh: Bluetooth (short range, within buildings), Wi-Fi mesh (mid range, community cluster), and LoRa (long range, bridges, hilltops, outlying sensors). Interview III [INT_003]
Key characteristics:
- Range: 5–10 km line-of-sight
- Bandwidth: very low (approximately dial-up ÷ 10); sufficient for sensor readings and text messages, not internet streaming Interview III [INT_003]
- Power: each node is solar + battery powered; approximately 2 weeks autonomy without sun Interview III [INT_003]
- Cost: individual nodes in the tens-to-hundreds of dollars range; approximately 1/10 the cost of equivalent council-grade sensors Interview III [INT_003]
- Self-configuring: Reality 2 platform enables nodes to auto-discover each other and form a network on startup, no manual configuration required Interview III [INT_003]
Architecture
A community mesh using LoRa typically includes:
- Sensor nodes (bridges, fields, waterways) — ESP32 or similar microcontroller, solar + battery, LoRa radio; measure environmental parameters (water level, temperature, etc.)
- Household devices — LoRa handhelds for text communication without GSM; remain functional when cellular networks are down
- Hilltop repeaters — solar + battery powered; extend LoRa range across terrain; can host local edge processing
- Central hub (church, marae, school) — more powerful PC or Linux machine with UPS; acts as local data aggregation point and cloud bridge when connectivity is available
Graceful degradation: at minimum, the network maintains emergency comms and sensor reads even when mains power, fibre, and GSM are all down. Additional capability (richer data, cloud sync, public dashboard) comes back online as infrastructure recovers. Interview III [INT_003]
Data sovereignty
The Trust Groups mechanism (part of Reality 2) assigns each device to an encrypted group sharing keys. Communities control what data is shared, with whom, and for what purpose — aligned with Māori kaitiakitanga principles. “The river owns its data, administered by Kaitiaki / the people who live there.” Interview III [INT_003]
NZ deployment: Mariko Earthgrids Wairoa pilot
East Coast NZ (Hawke’s Bay region); flood resilience use case. The community gets flooded in major weather events. Regional council has 3 sensors feeding a cloud dashboard inaccessible when bridges are down. Mariko’s response: approximately 10 lower-cost LoRa sensors deployed, ~40 more imminent; public dashboard plus tailored views for emergency controllers; community members annotate and contribute observations. Decentralised maintenance workforce: local residents install and maintain sensors; local welder fabricates bridge brackets and is paid from project budget. Interview III [INT_003]
Relevance to Neobiome
LoRa mesh is the D09 enabling technology for remote NZ communities where fibre is absent and GSM coverage is unreliable. It provides:
- Flood and disaster early warning infrastructure (i06_resistance_external_shocks)
- Community-owned and community-maintained digital infrastructure (i05_good_governance_transparency, i08_innovation_appropriate_technology)
- Foundation for a broader sensor network covering energy, water, and agricultural domains
Starlink or GSM can optionally serve as outbound internet bridges at a single community node; LoRa handles internal community comms independently of external connectivity. Interview III [INT_003]
