Abstract

An architecture and methods for extending the depth of a WLAN to a four-level hierarchal access point structure including wireless access points. The wireless access points in the WLAN can be networked by scanning for a network, collecting one or more packets that identify the network from one or more access points, each packet including an address identifying an ancestry of the access points to an ancestral wired access point; and applying an access point selection algorithm to configure a parent access point. The architecture includes a scanning object configured to issue a scan request to a network interface and collect access point data; a selection object configured to filter and sort the collected access point data; an authentication state machine configured to perform authentication and validate; and an association state machine configured to compose a packet including hierarchical data indicative of access point ancestry to a conventional access point.
