Which statement is correct regarding LoRa technology?

Low bandwidth with long range, limited by human factors
High bandwidth with long range, limited by human factors
Low bandwidth with long range, not limited by any factors
High bandwidth with long range, not limited by any factors

The correct answer is: Low bandwidth with long range, limited by human factors

LoRa technology is specifically designed for low-power wide-area networking (LPWAN) and is known for its unique combination of low bandwidth capabilities and long-range communication. This technology is particularly effective for applications that require transmitting small amounts of data over long distances with minimal power consumption, which is ideal for battery-operated devices often found in IoT scenarios. The primary characteristics of LoRa include its ability to cover long distances—often several kilometers in rural areas and around 2-5 kilometers in urban settings—while transmitting data at low rates. It excels in environments where devices need to communicate infrequently and only send small packets of data, such as sensor readings or status messages. Human factors may come into play regarding interference and local regulations, affecting the practical deployment and performance of the technology, but they do not fundamentally limit its inherent capabilities. The correct statement captures this core functionality of LoRa, emphasizing its low bandwidth, long-range capabilities, and some limitations imposed by external factors.
