Page 45: Vlan Support
VLANs collect and distribute data through wireless HP WL520 network interface cards (NIC). An Ethernet port on the access point typically connects a wireless cell to a wired backbone. They communicate across a VLAN-capable switch that reviews packet headers and directs traffic to the appropriate ports. -
Page 46: Vlan Workgroups And Traffic Management
The HP WL520 device assigns clients to one of two VLANs designated by a network name. First, each one of the wireless NICs in the HP WL520 device is configured with a unique network name and an 802.1Q-compliant VLAN identifier. Each NIC represents a VLAN. - Page 47 A “tagged” user VLAN is created when a VLAN ID between 1 and 4094 (per the 802.1Q standard) is configured for one of the wireless NICs and VLAN is enabled.

Page 48: Typical Vlan Management Id Configuration Scenarios
The VLAN feature enables all wireless clients that access the network through the same HP WL520, to be configured as members of the same VLAN. In this scenario, each wireless NIC is configured with the same VLAN ID. The same VLAN header or tag is then applied to all traffic received from wireless clients and transmitted on the wired or wireless backbone. -

Radio Specifications wireless communication range wireless communication range wireless communication range wireless communication range The range of the wireless signal is related to the composition of objects in the radio wave path, and the transmit rate of the wireless communication. Communications at a lower transmit range may travel longer distances. NOTE: The range values listed in the Communications Range Chart are typical distances as measured at the development laboratories.
