Emergency communication (grid/network-outage resilient)

Solutions

• Battery/solar-backed radio or satellite communicator: Keeps emergency communication working through a grid or network outage (cross-ref power storage and distribution).
• Local mesh / long-range radio network (LoRa): Short-range, low-power off-grid data links between buildings or sensors on the property; not an internet substitute, but resilient to a wider network outage.
