The 3Com Access Point 7250/8250/8750/8850 supports WDS Bridging, which provides a flexible way to 
extend a wireless network. With WDS Bridging, you can increase your network to large, open locations 
where pulling wire is cost-prohibitive, restricted, or physically impossible.

This guide explains how to configure a WDS link between two 3Com access points, and describes some 
common installation scenarios for using WDS Bridging.

Understanding WDS Bridging Support

A Distribution System (DS) is a network (typically a wired network) that interconnects separate access 
points into a single LAN. With WDS, the interconnection no longer needs to be physically wired. 
WDS uses the wireless medium to interconnect separate access points, thereby eliminating the cost and 
inconvenience that may hinder wire installations.

A WDS link can be used in a simple point-to-point link, a complex point-to-multipoint link, or a 
multilayer topology.

Point-to-Point WDS Link

The following example shows a point-to-point WDS link configured between two access points.

NOTE

: For more information on the access points, including complete installation and 

configuration instructions, see the 

Wireless LAN Access Points User Guide

 included on the 

product CD in PDF format.
