摘要
Zigbee是近年来出现的一种新兴的短距离无线通信技术,它采用了IEEE802.15.4标准作为其物理层和媒体接入层规范,具有低功耗、低成本和低复杂度的特点。它和Wi-Fi有着不同的应用空间,主要适用于自动控制、远程监控等领域,是Wi-Fi的有效补充。但是由于它们使用的是相同的频段,不可避免地会出现相互之间的干扰。对Zigbee和Wi-Fi的主要特性作了比较,分析了两者产生干扰的原因,在室内环境下具体分析了Zigbee对Wi-Fi的干扰情况,并且提出了两者共存问题的解决方法。
Zigbee is a recently developed short-distance wireless communication technology. It defines the network for the MAC and PHY Specifications of IEEE 802.15.4 and has the characters of low power consumption, low cost and low complexity. Zigbee and Wi- Fi have different applications. Zigbee fits the applications of auto control and remote monitor, and it is an effective complementarity for Wi-Fi. Due to using the same frequency band, it is not avoid that there exists interference between them. Zigbee is compared with Wi- Fi on the main characters, the interference reason of them is presented, and the impact of the interference on performance between Zigbee and Wi-Fi is analysed in the indoor environment in detail. At last, several solutions for improved coexistence are presented.
