Exactly. We have it where I work but its not just open for anybody to connect to it....and I dont mean security like knowing password. This is a very large oil refinery that i work in, pretty sizeable IT department. And unless its specificly business related....no wifi.
I don't think there is an area in our entire hospital that doesn't have WiFi. We have two networks campus-wide; a secure one that we can log on to (for our tablets and whatnot) and then a "guest" network for the patients and us if we want to use it. That must suck to not have WiFi available.
