ZigBee 与蓝牙技术的低功耗性能比较与测试研究

摘要

ZigBee and Bluetooth are the wireless communication technologies that play an important role in wireless ad-hoc networks. This paper analyzes and compares different low-power control strategies used by these technique standards,furthermore,observes the current consumption to reach a reasonable conclusion through the tests of these two typical applying circuits.ZigBee has a significant advantage in low-power consumption while Bluetooth 4.0 combines high-speed and low-power consumption to reduce the power consumption to a large extent.Generally speaking,ZigBee technology and Bluetooth technology have respective advantages, complementing while competing with each other.%ZigBee 与蓝牙都是无线通信技术，在无线自组网中有着重要作用。本文主要分析比较两种技术标准所采用的不同低功耗控制策略，同时通过对两种典型应用电路进行测试，观察消耗电流的情况并得出结论。ZigBee在低功耗方面有着重要的优势，而蓝牙4.0将低功耗与高速性相结合，也很大程度地降低了功耗。总体来说， ZigBee 技术与蓝牙技术各有优势，互为补充，又相互竞争。
