IEEE 802.1x provides a mechanism whereby wireless access can be granted to requesting devices (for example by laptops in a corporate environment) by verifying credentials from an authentication server. The authentication server is typically shared for access to other shared services like E-Mail.
Credentials typically come in form of a username/password pair and such a setup is most common in corporate environments where wireless access can be monitored based upon the user accessing the network and especially where such authenticating servers already exists for access to other services. The obvious advantage of using 802.1x secured routers is that the security layer has the least disruptive rollout as users are already accustomed to providing credentials to access other services.
