Create Multiple BSSIDs

In case you are confused as to the difference between SSID and BSSID, the author of this tutorial explains it nicely:

 

"There's much confusion about what the difference is between a SSID and a BSSID. Some routers can only create multiple SSIDs while others can create multiple BSSIDs. For now, it's only important to know that multiple BSSIDs is what you want if your router supports it. A BSSID is a truly seperate interface with its own MAC address, while multiple SSIDs share the same MAC address confusing many wireless clients (like PDAs) causing them to be unable to see some or all of the created wireless networks."

 

This is why you do not hear much about BSSID because all consumer wireless routers that I know, there is only one SSID.
