In infrastructure mode, WLAN clients connect to a central AP. The AP provides one or more wireless LAN networks. It regulates the client's rights to access the radio cell, communications between the clients, and access to further networks. In larger scale WLAN scenarios (e.g. in companies with offices extending between several buildings or floors) multiple APs can provide WLAN clients with access to a common, shared network. The clients can roam between the different APs, if necessary. A common term used here is "campus coverage" because this solution is used by a large number of colleges and universities to provide students and staff with network access.
