基于IEEE 802.15.4和ZigBee这两种低功率无线通信标准的家庭自动化（HA）产品开始出现在市场上。这些产品大多使用2.4GHz工业科学医疗（ISM）频段，与蓝牙、无绳电话、微波炉和WiFi等其他几种无处不在的技术共享无线频谱。跨技术干扰的可能性是存在的，并且它对基于IEEE 802.15.4标准的新HA产品的成功是迫在眉睫的威胁。我们为比利时市场开发了ZigBee家庭自动化产品线，因此决定评估我们的产品在拥挤的2.4 GHz频段中面临交叉技术干扰时的鲁棒性。我们在受控的实验室环境中将我们的产品暴露在越来越高的WiFi干扰水平下，并测量其性能。本文总结了我们的研究结果，并提出了建议和方法，以测量和避免WiFi干扰，同时部署和安装基于ZigBee的产品在家庭环境中。虽然ZigBee产品可以成功抵御来自微波炉和蓝牙设备的干扰，但它们仍然容易受到高负载WiFi流量的影响。ZigBee和WiFi可以在家庭环境中和平共处，只要采取一定的基本预防措施。
Home Automation (HA) products based on IEEE 802.15.4 and ZigBee, both low power wireless communication standards, are starting to appear on the market. Most of these products use the 2.4GHz Industrial Scientific Medical (ISM) band, sharing the wireless spectrum with several other ubiquitous technologies such as Bluetooth, cordless phones, microwaves ovens and WiFi. The potential for cross technology interference exists and it is a looming threat to the success of new HA products based on the IEEE 802.15.4 standard. We developed a ZigBee Home Automation line of products for the Belgium market and therefore decided to evaluate the robustness of our products in the face of cross technology interference in the crowded 2.4 GHz band. We exposed our product, in a controlled laboratory setting, to increasing levels of WiFi interference and measured its performance. This paper summarizes our findings and presents recommendations and a methodology to measure and avoid WiFi interference while deploying and installing ZigBee based products in a home setting. While ZigBee products can successfully withstand interference from microwave ovens and Bluetooth devices, they are still vulnerable to high load WiFi traffic. ZigBee and WiFi can peacefully coexist in the home environment as long as certain basic precautions are taken.
