The integration of heterogeneous wireless technologies is believed to aid revolutionary healthcare delivery in hospitals and residential care. Wireless medical device coexistence is a growing concern given the ubiquity of wireless technology. In spite of this, a consensus standard that addresses risks associated with wireless heterogeneous networks has not been adopted. This paper serves as a starting point by recommending a practice for assessing the coexistence of a wireless medical device in a non-line-of-sight environment utilizing 802.15.4 in a practical, versatile, and reproducible test setup. This paper provides an extensive survey of other coexistence studies concerning 802.15.4 and 802.11 and reports on the authors' coexistence testing inside and outside an anechoic chamber. Results are compared against a non-line-of-sight test setup. Findings relative to co-channel and adjacent channel interference were consistent with results reported in the literature.
异构无线技术的融合被认为有助于医院和家庭护理领域的医疗服务发生革命性变化。鉴于无线技术的普及，无线医疗设备共存问题日益受到关注。尽管如此，尚未采用一种共识标准来解决与无线异构网络相关的风险。本文通过推荐一种在非视距环境下利用 802.15.4 评估无线医疗设备共存性的实践方法，为解决这一问题提供了一个起点。该方法采用实际、通用且可重复的测试设置。本文还对其他涉及 802.15.4 和 802.11 的共存研究进行了广泛调查，并报告了作者在消声室内外进行的共存测试结果。将结果与非视距测试设置进行了比较。同信道和相邻信道干扰的结果与文献中的报告结果一致。
