The IEEE 802.11 standard defines a Wireless Distribution System (WDS) 

for bridge connections between access points. The Mini Broadband Router 

can use WDS to forward traffic on links between units.

Up to four WDS links can be specified for the Mini Broadband Router. 

The WDS feature enables two basic functions to be configured in the 

wireless network. Either a repeater function that extends the range of the 

wireless network, or a bridge function that connects a remote LAN segment 

to an Internet connection.
