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. Access points (APs) for the network may be widely distributed in various facilities, such as airports, mass-transit stations, and various businesses. The network may couple to a wide area network, such as the Internet. 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. Each of the access points may be operable to “listen for” or detect the identification information 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. Thus, the local network may provide various local resources which are available to users having a first access level, and users with a second access level may not be entitled to view or utilize these network resources on the network, but may be simply provided external Internet access.
