Abstract

A system and method for providing multiple access levels to users of a wireless network system. The network system includes a plurality of wireless access points coupled to a network. A portable computing device (PCD) of a user may store identification information which indicates an access or privilege level for the user of the PCD. The access level may determine the network access and/or services available to the user of the PCD. The identification information may include a System ID of the PCD. The network system may store a list of identification information and a corresponding list of access levels. When the access point receives the identification information from a PCD of a user, the access point may determine the appropriate access level for the portable computing device using the identification information. Network access and services may then be provided to the portable computing device at the indicated level.
