Emerging healthcare radio technologies are designed to operate in the 2.4GHz industrial, scientific and medical (ISM) band. Since both standardized (Bluetooth and Wi-Fi) and non-standardized (proprietary) devices use the same frequency band, the aggregate interference may significantly affect the performance of medical wireless systems. This paper characterizes the spatiotemporal spectrum occupancy and proposes models for the aggregate interference in hospital environments. In particular, time–frequency and cluster-based statistical models for the aggregate interference are developed based on network experimentation. The proposed models enable the design of wireless networks for e-health applications and medical services.

基于网络实验的医院频谱占用与干扰模型

新兴的医疗保健无线电技术旨在在 2.4GHz 工业、科学和医疗 (ISM) 频段中运行。由于标准化（蓝牙和 Wi-Fi）和非标准化（专有）设备使用相同的频段，因此总干扰可能会显着影响医疗无线系统的性能。本文描述了时空频谱占用的特征，并提出了医院环境中聚合干扰的模型。特别是，基于网络实验开发了用于集总干扰的时频和基于集群的统计模型。所提出的模型能够为电子健康应用和医疗服务设计无线网络。
