    • 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.
    • 一种用于向无线网络系统的用户提供多个访问级别的系统和方法。 网络系统包括耦合到网络的多个无线接入点。 网络的接入点(AP)可以广泛分布在机场,大众交通站和各种业务等各种设施中。 网络可以耦合到诸如因特网的广域网。 用户的便携式计算设备(PCD)可以存储指示PCD的用户的访问或特权级别的标识信息。 访问级别可以确定PCD的用户可用的网络访问和/或服务。 识别信息可以包括PCD的系统ID。 每个接入点可操作以“侦听”或检测PCD的识别信息。 网络系统可以存储识别信息的列表和对应的访问级别列表。 当接入点从用户的PCD接收到识别信息时,接入点可以使用识别信息确定便携式计算设备的适当的访问级别。 然后可以以指定的级别向便携式计算设备提供网络接入和服务。 因此,本地网络可以提供对具有第一访问级别的用户可用的各种本地资源,并且具有第二访问级别的用户可能无权在网络上查看或利用这些网络资源,但是可以简单地提供外部互联网 访问。
