Wireless Distribution System (WDS)

Wireless Distribution System (WDS) Settings

SMT-R2000 lets you connect multiple access points using a Wireless Distribution System (WDS). WDS allows access points to communicate with one another wirelessly in a standardized way. This capability is critical in providing a seamless experience for roaming clients and for managing multiple wireless networks. It can also simplify the network infrastructure by reducing the amount of cabling required.

WDS 설정

The following notes summarize some critical guidelines regarding WDS configuration. Please read all the notes before proceeding with WDS configuration. -->


Notes	When using WDS, be sure to configure WDS settings on both access points participating in the WDS link. You can have only one WDS link between any pair of access points. That is, a remote MAC address may appear only once on the WDS page for a particular access point. Both access points participating in a WDS link must be on the same Radio channel and using the same IEEE 802.11 mode. (See Configuring Radio Settings for information on configuring the Radio mode and channel.) When 802.11h is operational, setting up two WDS links can be difficult, as the operating channnel of the two APs may keep changing, depending on the channel usage and radar interference.

To configure WDS on this access point, describe each AP intended to receive hand-offs and send information to this AP. Each destination AP needs the following description


Item	Description
Radio	The Samsung AP is available as a one-radio or two-radio access point. One-Radio AP: On the one-radio version of SMT-R2000, this field is not included on the WDS tab. Two-Radio AP: For each WDS link on a two-radio AP, select Radio One or Radio Two. The rest of the settings for the link apply to the radio selected in this field. The read-only "Local Address" will change depending on which Radio you select here.
Local Address	Indicates the Media Access Control (MAC) addresses for this access point. A MAC address is a permanent, unique hardware address for any device that represents an interface to the network. The MAC address is assigned by the manufacturer. You cannot change the MAC address. It is provided here for informational purposes as a unique identifier for the access point or interface. One-Radio AP: On a one-radio access point, a single MAC address is shown at the top of the WDS settings page. The address shown for the one-radio AP is the MAC address for that radio AP. This is the address by which the AP is known externally to other networks. Two-Radio AP: For each WDS link on a two-radio AP, the Local Address reflects the MAC address for the Internal interface on the selected radio (Radio One on `WLAN0` or Radio Two `WLAN1`).
Remote Address	Specify the MAC address of the destination access point; that is, the access point to which data will be sent or "handed-off" and from which data will be received, in other words the AP to which you are creating the WDS bridge. Click the drop-down arrow to the right of the Remote Address field to see a list of all the available MAC Addresses, their associated SSIDs and Signal Levels on the network. Select the appropriate MAC address from the list. Note: The SSID displayed in the drop-down list is simply to help you identify the correct MAC Address for the destination access point. This SSID is a separate SSID to that which you set for the WDS link. They two do not (and should not) be the same value or name.
Bridge with	Network to be connected to WDS link. By default, internal network is used.

If you does not care about WDS link security, encryption type is not required to be decided. If not, Static WEP can be selected as the encryption type.


Encrytion Type	Description
None	If you set encryption to None, the data sent between the APs across the WDS bridge will not be encrypted, but rather will be sent as plain text.
WEP	Specify whether you want Wired Equivalent Privacy (WEP) encryption enabled for the WDS link. Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. Both access points on the WDS link must be configured with the same security settings. For static WEP, a static 64-bit (40-bit secret key + 24-bit initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV) Shared Key for data encryption. For more information on WEP security, see Static WEP

Setting WDS Link Security Mode to None

If you select None as your preferred WDS encryption option, you will not be asked to fill in any more fields on the WDS tabbed page. All data transferred between the two APs on the WDS link will be unencrypted.

Setting WDS Link Security Mode to WEP

If you select WEP as your preferred type of encryption on the WDS link, a number of additional fields will appear on the WDS tabbed page.


Item	Description
Encryption	WEP
WEP	Select this option if you want to set WEP encryption on the WDS link.
Key Length	If WEP is enabled, specify the length of the WEP key: 64 bits 128 bits
Key Type	If WEP is enabled, specify the WEP key type: ASCII Hex
Characters Required	Indicates the number of characters required in the WEP key. The number of characters required updates automatically based on how you set Key Length and Key Type.
WEP Key	Enter a string of characters. If you selected "ASCII", enter any combination of `0-9`, `a-z`, and `A-Z`. If you selected "HEX", enter hexadecimal digits (any combination of `0-9` and `a-f` or `A-F`). These are the RC4 encryption keys shared with the stations using the access point.
