Wireless technologies as part of the data communication infrastructure of modern hospitals are being rapidly introduced. Even though there are concerns about problems associated with wireless communication security, the demand is remarkably large. Herein we discuss security countermeasures that must be taken and issues concerning availability that must be considered to ensure safe hospital/business use of wireless LAN systems, referring to the procedures introduced at a university hospital. Security countermeasures differ according to their purpose, such as preventing illegal use or ensuring availability, both of which are discussed. The main focus of the availability discussion is on signal reach, electromagnetic noise elimination, and maintaining power supply to the network apparatus. It is our hope that this information will assist others in their efforts to ensure safe implementation of wireless LAN systems, especially in hospitals where they have the potential to greatly improve information sharing and patient safety.
作为现代医院数据通信基础设施一部分的无线技术正在迅速得到应用。尽管人们对无线通信安全相关问题存在担忧，但需求却非常大。在此，我们参考一所大学医院所采用的程序，讨论为确保医院/业务安全使用无线局域网系统而必须采取的安全对策以及必须考虑的可用性问题。安全对策因其目的不同而有所差异，例如防止非法使用或确保可用性，本文将对这两方面进行讨论。可用性讨论的主要重点在于信号覆盖范围、电磁噪声消除以及维持网络设备的供电。我们希望这些信息将有助于其他人努力确保无线局域网系统的安全实施，尤其是在医院，因为无线局域网系统有潜力极大地改善信息共享和患者安全。
