Hello, I focus on low-power communication protocols to preserve battery life in my IoT projects. There are options like LoRaWAN, Bluetooth Low Energy, Zigbee, but which one is more suitable for which scenario? How should we evaluate data rate, range, power consumption, and network topology to make a decision? What do you think are the critical factors we should prioritize when choosing a protocol? Would love to hear your thoughts!
How do you choose low-power communication protocols for IoT devices?

LoRaWAN excels in long-range, low data rate, and power efficiency, while Zigbee offers high stability indoors thanks to its mesh structure. BLE, on the other hand, is fast and ideal for short-range smartphone connectivity. When choosing, first assess the communication range and required data volume, then evaluate battery capacity and network topology.
In scenarios with high data transmission frequency, such as when sensors send data every second, which would be easier to implement: BLE or LoRaWAN? Also, how much do you think the network topology—whether mesh or star—affects power consumption?
