Example; Security - HP MSM7xx Management And Configuration Manual

Public/guest network access
Location-aware authentication

Example

Consider the following topology for a fictional small hotel. The restaurant and lounge are
available to all hotel users who subscribe to the wireless service. However, the conference
room is available only to a specific group of guests who book it in advance.
Conference Room
In this example, the access points in each area are assigned the following unique group
names:
 conference_room
 restaurant
 lounge
When a user logs in, server-side code can be used to determine the access point they are
associated with by inspecting the Called-Station-ID. Then, using user's account information,
access can either be granted or denied.

Security

The controller accepts location-aware information only from MSM APs that have a matching
shared secret to its own.
