But instead of connecting via USB, Cardbus or other computery interfaces, they connect via Ethernet. Some products don’t use WDS at all and instead act like wireless client adapters. WDS isn’t the only way to bridge and repeat, however. The repeating throughput reduction applies both to WDS and non-WDS repeating. This is because all transmissions use the same channel and radio and must be retransmitted to reach the wired LAN. an AP that data flows through before hitting the wired network. Note that wireless throughput is cut approximately in half for each repeating “hop”, i.e. Whatever encryption is supported in the WDS link is what the repeater’s clients must use. Static WEP keys are more commonly supported in WDS connections. This means that Wi-Fi Protected Access (WPA / WPA2) and other dynamic key assignment technology might not be available.

Dynamically assigned and rotated encryption keys are not generally supported in a WDS connection.

It’s more difficult to set up than non-WDS.

Wireless Repeating in which APs communicate with each other and with wireless STAs.

Wireless Bridging in which WDS APs communicate only with each other and don’t allow wireless clients or Stations (STA) to access them.

WDS can be used to provide two modes of wireless AP-to-AP connectivity:

(Broadcom apparently included WDS support in its AP reference design code.) It wasn’t until products based on Broadcom‘s 802.11g chipset started to hit the market at the beginning of 2003 that the WDS term started to be commonly used. Though these products were actually making use of the WDS feature, they didn’t refer to it as such. Other companies soon followed with similar upgrades, and also introduced dedicated Wireless Bridges, such as Linksys’ WET11.

This upgrade created the first consumer-priced WLAN product to support bridging and repeating.

D-Link first broke the artificially high wireless bridging price barrier by releasing a free upgrade to its DWL-900AP+ Access Point. Many of these implementations were based around a medium access control (MAC) layer design originated by a long-defunct company called Choice Microsystems.ĪPs with wireless bridging features remained as high-priced items until fall 2002 when wireless bridging moved into consumer priced wireless products.

expensive, 802.11b products in the late 1990’s. But it was enough to allow bridging features to first be added to enterprise-grade, i.e.

The provision for four MAC addresses in a frame is about the only thing covered by the 802.11 standards. (In the 802.11 frame header, address 1 is the destination address, address 2 is the source address, address 3 is the BSSID of the network and address 4 is used for WDS, to indicate the transmitter address.) WDS connections are MAC address-based and employ a special data frame type that uses all four of the (MAC) address fields allowed in the 802.11 standard, instead of the three addresses used in normal AP STA (client) traffic. WDS, which stands for Wireless Distribution System, is a feature that enables single-radio APs to be wirelessly inconnected instead of using a wired Ethernet connection. Please read references to access points (AP) as applying to either access points or wireless routers unless otherwise noted. This article will review the basics of WDS-based wireless repeating and I’ll then walk through setting up a few examples. But properly configuring them often isn’t easy. Many Wi-Fi routers come equipped with wireless repeating capabilities. Introduction Updated : Clarify encryption support
