This MAC address may belong to the radio or to another MAC address generated on the AP. When the AP is serving only onenetwork, it is called a Basic Service Set Identifier (BSSDD, BasicServiceSet Identifier) o The AP has the ability to use multiplethe ability to use multiple SSIDs. This allows the same AP to provide both a Guest network and a Coiporate network.When the AP has multiple networks, it is referred to as a Multiple Basic Service Set Identifier (MBSSID).Identifier) o The AP can be thought of as a virtual AP that serves multiple networks, but uses the same hardware.
