WLANs are increasingly popular because they enable cost-effective connections among people  and  applications  that  were  not  possible  in  the  past. For  example，  WLAN-based applications can enable fine-grained management of supply （）  to improve their efficiency and  reduce （）.WLANs can also enable entirely new business processes.To cite but one example， hospitals are using WLAN-enabled point-of-care   （）   to reduce errors and improve overall patient care.WLAN management solutions provide a variety of other benefits that can be substantial but difficult to measure.For example， they can protect corporate data by preventing （）  through  rogue  access  points. They  can  improve  overall  network  management  by integrating  with  customers’existing  systems. Fortunately，  it  isn’t  necessary  to measure  these benefits  to  justify  investing  in  WLAN  management  solutions，  which  can  quickly  pay  for themselves simply by minimizing time- （）   deployment and administrative chores.
