Access Points that are not VLAN-capable typically transmit broadcast and 
multicast traffic to all wireless Network Interface Cards (NICs). This 
process wastes wireless bandwidth and degrades throughput 
performance. In comparison, VLAN-capable AP is designed to efficiently 
manage delivery of broadcast, multicast, and unicast traffic to wireless 
clients. 

The AP assigns clients to a VLAN based on a Network Name (SSID). The 
AP can support up to 16 VLAN/SSID pairs per radio. (Note that 802.11b 
APs (Single or Dual-radio models) and 5 GHz Upgrade Kits (for 
Dual-radio APs) can only support one VLAN/SSID per radio.)

The AP matches packets transmitted or received to a network name with 
the associated VLAN. Traffic received by a VLAN is only sent on the 
wireless interface associated with that same VLAN. This eliminates 
unnecessary traffic on the wireless LAN, conserving bandwidth and 
maximizing throughput.

In addition to enhancing wireless traffic management, the VLAN-capable 
AP supports easy assignment of wireless users to workgroups. In a 
typical scenario, each user VLAN represents a workgroup; for example, 
one VLAN could be used for an EMPLOYEE workgroup and the other, for 
a GUEST workgroup.
