802.11 IEEE defines the mechanical process of how WLANs are implemented in the 802.11 standards so that vendors can create compatible products. The 802.11 WLAN standards include 802.11a, 802.11b, 802.11g, and 802.11n.
802.1Q IEEE 802.1Q is a trunking standard that supports two types of frames: tagged and untagged.
