IN-BAND DEVICE ENROLLMENT WITHOUT ACCESS POINT SUPPORT
First Claim
1. A method, comprising broadcasting, from a host computer communicatively coupled to an access point of a wireless network, a series of broadcast packets encoding at least one network configuration parameter within the lengths of said broadcast packets, so as to enable a wireless device configured to decode the at least one network configuration parameter to join the wireless network upon receiving the series of broadcast packets.

Abstract
In one embodiment, the invention provides a method for configuring a wireless device, so as to enable the wireless device to join a secured wireless network, by broadcasting a series of broadcast packets encoding a network configuration parameter (e.g., a shared secret key) from a computer coupled to a wireless access point to the wireless device. The information representing the network configuration parameter is encoded, not within the payload portion of the packet, but within the length of each broadcast packet in the series of broadcast packets. Accordingly, a wireless device that has not yet been configured to receive packets from the wireless access point can observe the information encoded in the length of each broadcast packet, and thereby decode the network configuration parameter and join the network.
