What wireless technology has the lowest level of power consumption?

Bluetooth Low Energy (BLE) is one of the wireless technologies known for its low power consumption. It is designed specifically for devices that require intermittent communication and can operate for extended periods on small batteries. By using short burst transmissions and having low duty cycles, BLE significantly reduces energy usage compared to traditional Bluetooth and other wireless technologies. This makes it ideal for applications in wearables, smart home devices, and IoT sensors.
