Basic concepts in WDS

The WDS feature provides a single hop wireless link between two APs, including:

Link formation—Connections made based on the messages exchanged between two peer nodes.

Link security—Provides PSK plus CCMP security.

Advantages of WDS

At present, 802.11 based WLAN technologies are widely applied in the home, SOHO, and enterprise
scenarios.
APs are connected through cables, switches, routers and power supplies. As a result, the wireless

network is complex, costly and no longer wireless, and it requires a lot time to deploy a network.
WDS provides wireless connectivity between separate LAN segments to simplify WLAN deployment.
WDS has the following advantages:

Low cost for high performance deployment options

Expansion availability without the need for new wiring or more access points

Easy deployment in scenarios such as metros, companies, offices, large warehouses, manufacturing
divisions, ports, and waterfronts.

Deployment scenarios

The WDS feature supports the following three topologies.
Topology 1 Peer to Peer Connection [Point to Point]: In this topology, two neighbor MPs form a bridge

between two LANs. In

Figure 91

, AP 1 and AP 2 bridge 802.3 data between LAN segments 1 and 2 by

converting it to 802.11s format and sending it over a wireless link.

Topology 2 Centralized Bridging [Point to multipoint]: In this topology, a centralized bridging device

forms wireless links with multiple MPs to bridge data among multiple LAN segments. As shown in

Figure

, data transferred between different LAN segments goes via AP 1.
