Abstract#1248111Hazem H. RefaiThe number of radio-frequency (RF) wireless technologies utilized in healthcare facilities and medical devices is significantly increasing. This phenomenon brings to the forefront many issues and concerns, in particular the potential of hacking, spoofing, and interference from surrounding wireless networks. This is especially true for those operating in the license-free RF spectrum, including the Industrial, Scientific, and Medical (ISM) bands. Recognizing the potential interference among ISM devices, including those of medical use, the Federal Communication Commission (FCC) on May 17, 2012 allocated the 2.36-2.4 GHz spectrum band for Medical Body Area Network (MBAN). This spectrum will be promoted for medical devices, enabling them to operate outside the heavily used ISM bands. Although the MBAN spectrum no longer shares bandwidth with the ISM spectrum, it remains an adjacent channel. Careful evaluation of MBAN devices is necessary to avoid adjacent channel interference. This project proposes the development of wireless coexistence testing protocols for medical devices. Two complementing approaches will be investigated. The first approach will be characterized by an environment that incorporates a variety of wireless networks and technologies, e.g., IEEE 802.11a/b/g/n, Bluetooth, Zigbee, ultra wideband, cordless phones, and RF identification tags. Medical devices will then be evaluated for coexistence by exposing them to real-world, heterogeneous wireless networks using a prescribed methodology. The second approach will utilize vector signal generators (VSG) to emulate wireless signals. Typically, VSGs are fully configurable and able to generate a signal identical in frequency, modulation, and bandwidth to those of offending wireless signals. However, VSGs don?t implement ?listen-before-talk?, thus lacking thorough evaluation of coexistence.

摘要：#1248111Hazem H. refai射频（RF）无线技术在医疗设施和医疗设备中的应用数量正在显著增加。这种现象带来了许多问题和关注，特别是潜在的黑客攻击、欺骗和来自周围无线网络的干扰。对于那些在免许可射频频谱（包括工业、科学和医疗（ISM）频段）中工作的人来说尤其如此。美国联邦通信委员会（FCC）认识到ISM设备（包括医疗设备）之间的潜在干扰，于2012年5月17日为医疗机构区域网络（MBAN）分配了2.36-2.4 GHz频段。该频谱将推广用于医疗设备，使其能够在大量使用的ISM频段之外运行。虽然MBAN频谱不再与ISM频谱共享带宽，但它仍然是相邻信道。仔细评估MBAN设备是必要的，以避免相邻信道的干扰。本项目提出了医疗设备无线共存测试协议的发展。将研究两种互补的方法。第一种方法的特点是集成各种无线网络和技术的环境，例如IEEE 802.11a/b/g/n、蓝牙、Zigbee、超宽带、无绳电话和射频识别标签。然后，通过使用规定的方法将医疗设备暴露于真实世界的异构无线网络，对其共存进行评估。第二种方法将利用矢量信号发生器（VSG）来模拟无线信号。通常情况下，vsg是完全可配置的，并且能够在频率、调制和带宽上产生与违规无线信号相同的信号。然而，vsg没有。先听后说？，因此缺乏对共存的彻底评估。
