CWISA-103 · Question #35

Which wireless technology is MOST appropriate for low-power sensors that must operate for multiple years on a coin-cell battery?

The correct answer is B. LoRaWAN. LoRaWAN is optimized for extremely low power consumption and long-range communication, allowing sensors to operate for years on small batteries. Wi-Fi and Bluetooth Classic consume too much power, and Zigbee, although low-power, does not match LoRaWAN's battery longevity.
