Design takeaway
When designing IoT systems, prioritize LoRa for applications where long range and low power are paramount, and data transmission needs are minimal and infrequent.
How to apply
When prototyping an IoT sensor that only needs to send small, infrequent readings (e.g., temperature, humidity), LoRa is a strong candidate for its power efficiency and range. If the sensor needed to send images or video, LoRa would be unsuitable.
Project actions
- 01When selecting a wireless technology for your design project, consider the trade-offs between range, power, and data speed.
