Configuring ESSIDs
An ESSID (Extended Service Set Identifier) is the name of the network. Wireless devices must
connect to a specific ESSID which determines the pre-defined set of privileges, settings, and
limitations (such as security definitions, access privileges, VLAN assignments, etc.) of the network.
Each channel can support multiple ESSIDs, thus creating “virtual” networks on the same channel.
The following is the data structure used by the Extricom system:
