Abstract

A beacon method for use in a wireless communication network involves populating a beacon frame'"'"'s channel identification data with accurate data associated with use of a particular channel for wireless communication; populating the beacon frame'"'"'s network identification data with data including at least one false data element wherein it can be determined if an intruder has attempted to connect to the network by detecting the false data element in the intruder'"'"'s attempt to connect to the network, where the beacon network identification data are intended to identify the network using the particular channel; storing the beacon frame in a computer readable storage medium; and transmitting the beacon frame over a channel to be reserved. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
