A preliminary study of low power wireless technologies: ZigBee and Bluetooth Low Energy

Low power design of wireless technologies is a critical point for future Internet of things (IoT) applications. In this paper, we provide a preliminary study of low-power wireless communication standards: ZigBee and BLE, evaluating their main features and behaviors in terms of various metrics, including the transmission time, data coding efficiency, power consumption, and delivery ratio. It is believed that the study presented in this paper would benefit application engineers in choosing an appropriate low-power wireless protocol.
