在这项工作中，我们提出了无线体域网 (WBAN) 和无线局域网 (WLAN) 的共存研究。目的是评估 WBAN 系统在现实医疗环境中的可行性，评估其抗干扰能力。我们通过物理 (PHY) 层模拟和医院病房中的实验干扰测试相结合，重点评估并置 IEEE 802.11g WLAN 干扰源对 IEEE 802.15.4/ZigBee 收发器性能的影响。为了更好地理解底层通信模型，我们还进行了信道测量、信道建模和功率谱测量。显示了不同系统配置和节点拓扑的 ZigBee 性能，深入了解影响病房系统性能的主要因素。此外，还提供了高性能操作的建议。
In this work, we present a coexistence study for wireless body area networks (WBAN) and wireless local area networks (WLAN). The aim is to evaluate the feasibility of WBAN systems in realistic medical environments, assessing their robustness to interference. We focus on the evaluation of the impact of a collocated IEEE 802.11g WLAN interferer on the performance of IEEE 802.15.4/ZigBee transceivers, through a combination of physical (PHY) layer simulations and experi- mental interference tests in a hospital room. In order to have a better understanding of the underlying communication model, we have also conducted channel measurements, channel modeling and power spectrum measurements. The performance of ZigBee for different system configurations and node topologies is shown, providing insights into the main factors that affect the system performance in a hospital room. In addition, recommendations for high performance operation are provided.
