Working with a Wireless Distribution System

Deploying the WDS System

SCALANCE WLC711

User Guide, V8.11, 07/2012, C79000-G8976-C260-03 11-11

Link Security

The WDS link is encrypted using Advance Encryption Standard (AES).

Note:

The keys for AES are configured prior to deploying the Repeater or Satellite Wireless APs.

Deploying the WDS System

Before you start configuring the WDS Wireless APs, you must ensure the following:

• The Wireless APs that are part of the wired WLAN are connected to the wired network.

• The wired Wireless APs that will serve as the Root AP/Root APs of the proposed WDS

topology are operating normally.

• The WLAN is operating normally.

Planning the WDS Topology

You may sketch the proposed WLAN topology on paper before you start the WDS deployment

process. You should clearly identify the following in the sketch:

• WDS Wireless APs with their names

• Parent-child relationships between Wireless APs

• Radios that you will choose to link the Wireless AP’s parents and children

Provisioning the WDS Wireless APs

This step is of crucial importance and involves connecting the WDS Wireless APs to the enterprise

network via the Ethernet link. This is done to enable the WDS Wireless APs to connect to the

SCALANCE IWLAN Controller so that they can derive their WDS configuration.

The WDS Wireless AP’s configuration includes pre-shared key, its role, preferred parent name and

the backup parent name.

Note:

The provisioning of WDS Wireless APs must be done before they are deployed at the target location. If the

Wireless APs are not provisioned, they will not work at their target location.

WDS Deployment Overview

The following is the high-level overview of the WDS deployment process:

1. Connecting the WDS Wireless APs to the enterprise network via the Ethernet network to

enable them to discover and register themselves with the SCALANCE IWLAN Controller. For

more information, see “Discovery and Registration Overview” on page 3-9.

2. Disconnecting the WDS Wireless APs from the enterprise network after they have discovered

and registered with the SCALANCE IWLAN Controller.

3. Creating a WDS VNS.

4. Assigning roles, parents and backup parents to the WDS Wireless APs.
