WLANs can also enable entirely new business processes. To cite but one example, hospitals are using WLAN-enabled point-of-care applications to reduce errors and improve overall(68) care. WLAN management solutions provide a variety of other benefits can be substantial but difficult to measure. For example, they can protect corporate data by preventing(69) through rogue access points. They help control salary costs, by allowing IT staffs to manage larger networks without adding staff. And they can improve overall network management by integrating with customers' existing systems, such as Open View and UniCenter.

参考答案和解析
正确答案： D
解析： 分析敏锐的供应商认识到，昂贵的成本不允许他们继续使用分隔的业务网络支持老版本的X.25协议和异步网络元素。例如，维护多个网络需要更多的人员。通常情况下，这些人员必须接受多家提供商的培训，有时甚至需要在每个平台上安排多个并行的工作团队。因此，必须维持额外的维护过程，且复制多个管理记录。成倍的传输设备用在交叉的网络通信中，这是资源的无效使用。而且，毫不奇怪的是，更多的技术安装在一个中心办公室，这意味着需要更大的物理空间，增大的电力连接和消耗。因此，把这些老的网络设备移植到基于IP的数据通信网络中是不符合逻辑的策略。

    解析： 分析在过去，应用和数据难以获得或者获得的成本很高，现在，因为WLAN能使人们之间互连的性价比很高，从而得到了广泛的应用。例如，基于WLAN的应用能使供应链得到很好的管理，提高效率并减少经费开支。WLAN使新的业务流程成为可能。作为一个例子，医院正在使用基于WLAN的护理点应用，以便减少错误，改进对病人的全面护理工作。WLAN管理方案提供了一系列的其他好处，这些好处是很实在的，但是又难以度量。例如，它可以防止通过欺诈访问点的方式的入侵，以保护企业数据。WLAN允许IT团队在不增加人员的基础上管理更大的网络，从而有助于控制薪水开支。WALN通过集成客户已有的系统，如OpenView和UniCenter等，有助于加强全面网络管理。幸运的是，我们不必度量这些好处来证明对WLAN管理方案的投资是正确的，WLAN管理方案只需使耗时的部署工作和事务性工作得以最小化，就可以很快得到补偿。
