Features & Benefits



» Consistent user authentication and

security policies. Easy identification of

failed AP, easy swapping with new AP.



» Security can be pre-set and RF

channels auto-adjusted for each AP.

When an AP is removed or added,

switch automatically configures new AP

with same configuration of replaced unit.

Sensitive information not locally stored

at the AP.

» WEP, WPA/WPA2 data encryption,

802.1Q VLAN, up to 8 SSID per

wireless frequency band.

» Continuous connection for each wireless

user, better network security.

» Wireless signals roamed not only across

to AP connected to same switch, but

also across AP connected to different

switches, using inter-switch roaming.

» Fast signal roaming across AP at Gigabit

speed. More difficult for thieves to

intercept when signals are roamed via

Ethernet cables.

» No restriction on port usage. Any switch

port can be used for wired or wireless

purposes.

» All switch ports support 802.3af PoE.

AP supports 802.3af PoE, can be

installed on high walls or ceilings away

from AC power outlets. Switch’s rack-

mount design allows it to be hidden in

equipment rack.



» Each switch can manage up to 48 AP. Up

to 4 switches can be gradually added in a

peer-to-peer configuration as more AP are

deployed.

» Identification of intruding AP for

administrators to take proper actions.

Wireless switching - an evolution in wireless LAN - is designed to simplify installation

and enhance the effectiveness of a medium-sized or large Wi-Fi network. It allows

businesses to install a high-performance, secure, manageable and scalable unified

wired/wireless network.

Wireless switching consists of one or multiple switches, and multiple wireless access

points (AP). The switches are core units that consolidate the security, manage the

bandwidth and maintain the intelligence of the entire wireless network. In addition to

monitoring users’ identities and maintaining their authentication as they roam, these

switches can configure and control all aspects of the AP, including: RF channel and

power management, wireless traffic segmentation, AP roaming and load balancing,

rouge AP detection and AP access security. The AP can be dispersed throughout

a site and directly attached to these switches, or indirectly connected through any

Ethernet switch.

Traffic from wireless users is roamed not only across to the access points, but

also among the peer wireless switches. In addition to intra-switch roaming, roaming

across different subnets is also supported for secure wireless connection across

multiple departments in a large enterprise. As roaming is through the Ethernet cable

at the fast Gigabit speed, traffic bottlenecks are minimized and overall network

performance is enhanced.

The AP, no matter where installed, are automatically discovered and centrally

managed. As users move around the wireless network, all data information,

translation, authentication paths and user tracking are executed on the switch end

to provide network administrators with a consolidated and secure wireless system.

» In a unified LAN/WLAN deployment,

D-Link’s wireless switching architecture

allows the switches to be placed deep

inside an existing wired network, say

in a data center, to protect current

investments in infrastructure. Wireless

traffic is tunneled to the switches for

centralized data forwarding decision. An

alternative would be to put the switches

at the network edge for minimized users’

distance from the AP, flexible scalability

and distributed peer-to-peer WLAN

switching.
