Vocera uses the following terminology to refer to the sites at your installation:
The home site is the usual physical site of a user, group, location, address book entry, or device. See About the Home Site.
The current site identifies the physical site where a user is currently located. See About the Current Site.
The Global site is a virtual site that does not correspond to any physical site. You can assign users, groups, locations, address book entries, or devices to the Global site if you do not want to associate them with a physical site. See About the Global Site.
