Market update business wlan

Centralized WLAN Solution Becomes Main Stream

Revenue from sales of WLAN switches and controllers increased 92% year on year, totalling $572 million (equivalent to 43% of the WLAN market revenue).

The business market will continue the gradual shift from the traditional stand-alone WLAN architecture to the newer, centralized one (WLAN switches and controllers managing coordinated access points) in 2007

Shipments of coordinated access points are forecast to account for 71 percent of the total enterprise-class access point shipments by 2010

Flexible deployment2


Flexible Deployment

  • Adaptable Wireless

    • Wireless traffic can be local-switched at the AP or Central-switched at the Unified Switch depending on users’ needs

    • No need to purchase additional license or upgrade firmware

Unified Switch

Server Farm

  • Local-Switched (Non-Tunnel Mode)

  • Better performance

  • Central-Switched (Tunnel Mode)

  • Better centralized security control

Unified Switch




Pre-set Configuration and Centralized Management

  • Security can be pre-set and management of AP can be centralized

    • The Profile configuration is applied to a managed AP on the event such as when an AP initially transitions to managed mode, or when AP is reset.

    • Unified Switch will automatically detect all APs attached to the switch

    • When an AP is removed or added, switch automatically configures new AP with same configuration of replaced unit

APs detected on the network

Pre-set Configuration and Centralized Management

  • Central Policy Control

    • Security setting/configuration can be saved even when the AP is powered off.


Unified Switch

  • Content of pre-set profile configuration packet:

  • RADIUS server settings

  • Security settings

  • Radio configuration

  • SSIDs, VLAN & Tunnel setting

  • QoS configuration


Access points attached to the network

RF Management

  • Automatic channel adjustment

    • Unified Switch automatically adjusts channels in the controlled Access Points in an event such as a new AP being added or being removed

    • Unified Switch can be programmed to automatically readjust channels periodically at certain time or upon a certain interval.

RF Management &

Self-Healing Wireless Network

  • Automatic power adjustment

    • Automatically adjust the RF signal to broadcast far enough to reach wireless clients, but not so far that it interferes with RF signals broadcast by other APs

    • When a Managed AP is powered down, the power of its neighboring AP(s) managed by the same switch is immediately increased by20% (Fail-safe feature).

Load Utilization

  • Unified Switch performs load utilization across the switch-managed access points on per radio basis based on AP’s utilization rate.

  • The APs report bandwidth utilization to the Unified Switch regularly

  • If the bandwidth utilization reaches a configured threshold then the new client associations are rejected. The new client will be forced to connect to an overlapped neighbor AP with lower utilization.

Default bandwidth utilization: 60%

Utilization rate increased

L2 Roaming

L3 Roaming

Fast Roaming

  • Ideal for VoIP Application

  • Fast L2/L3 Roaming

    • One DWS-3000 switch can support fast roaming across up to 48 APs.

    • This fast roaming can be supported with in a subnet (Layer 2) or across subnet boundaries (Layer 3).

Subnet B

Subnet A




Fast roaming
Fast Roaming

  • Inter-Switch Roaming

    • 4 Peer Switches in the same Roaming group

      • Not only can D-Link’s DWS-3000 support fast roaming between APs being managed by a particular switch, but can support up to 4 peer Unified Switches in a roaming group.

    • Support up to 192 APs

      • Since each switch can support up to 48 APs, this means up to 192 APs can be supported in a mobility group or domain.

Pre-Shared Keys


  • Fast Roaming

  • No relocating IP

  • Re-auth time is tiny



Dynamic Keys (WPA2 Enterprise)


Radius Server

  • Fast Roaming

  • No relocating IP

  • Re-auth time is tiny – the dynamic key - PMK (Pairwise Master Key) can be cached in Switch and forwarded to APs in the same roaming group

  • Management of thousands of users is possible

Comprehensive network management
Comprehensive Network Management

  • D-Link Unified Access System includes a set of comprehensive management functions for managing and monitoring the WLAN by using one of the three methods provided

    • Web-based management interface

    • Command-Line Interface (CLI)

      • The command-line interface (CLI) is a text-based way to manage and monitor the system. CLI can be accessed by using a direct serial connection or by using a remote logical connection with Telnet or SSH.

    • Simple Network Management Protocol (SNMP)

      • The D-Link Unified Switch uses both standard public MIBs for standard functionality as well as a number of additional private MIBs for additional functionality supported by the switch.

Monitoring All Access Points

  • Shows summary information about managed, failed, and rogue access points the switch has discovered or detected.

  • The font color for the AP listing indicates that the AP is one of the following types:

    • Green—Managed AP

    • Red—Failed AP

    • Gray—Rogue AP

    • Amber—Peer Managed AP

Monitoring All Access Points

  • Provides a variety of information about each AP that the switch manages.

    • Status tab provides configuration and association information about managed APs and their neighbors.

    • Statistics tab displays information about the number of packets and bytes transmitted and received on different interfaces.

Monitoring Associated Clients

  • Shows a variety of information about the wireless clients that are associated with the APs the switch manages.

  • Authenticated Client info can be logged by SNMP Trap or Syslog.

Monitoring and Managing

Ad-Hoc Clients

  • View and manage wireless clients that are connected to the WLAN through an ad hoc network.
