Abstract

System and method for providing access to multiple wireless service providers (WSPs) on a shared network infrastructure. The system includes a plurality of access points (APs) coupled to a network which may be distributed in airports, mass-transit stations, businesses, etc. The network may couple to a wide area network, such as the Internet. Each AP may include a plurality of virtual APs (VAPs), each corresponding to a WSP. A portable computing device (PCD) of a user stores identification information indicating a WSP of a plurality of possible WSPs, and which may include an access level of the user. Each AP “listens for” or detects identification information associated with numerous WSPs. When the AP receives the identification information from the PCD, it determines the VAP/WSP for the PCD using the identification information. Network access is then provided to the PCD through the determined WSP at the determined access level.
