Which description best describes the LoRa bandwidth and range in relation to physical limits and human limits?

LoRa achieves long-range communication by using very narrow bandwidth, which increases receiver sensitivity and thus the link budget. That means you can cover greater distances even though the data rate is kept low. In real deployments, how far the signal can go is often restricted more by human factors—regulatory limits on transmit power, duty-cycle rules, and spectrum usage—than by the raw physics of propagation. So the description that best matches this balance is low bandwidth paired with long range, with the limiting factors largely coming from human/regulatory constraints rather than fundamental physics.
