Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual The Spanning Tree Protocol implemented is IEEE 802.1d compatible. The algorithm forms a loop-free network by blocking traffic between redundant links in the network. These blocked links are placed in a standby condition, and may be automatically enabled to repair the network if another link is lost. The Spanning Tree Algorithm maintains a single path between all nodes in a network, by forming a tree-like structure.
Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual A WDS bridge interface allows traffic to be bridged to another Access Point on the same IP network. WDS bridge interfaces do not require additional IP Address configuration, as they are bridged with the standard wireless interface that is used for connections to associated clients. All of the WDS interfaces on the one Access Point may be bridged if required.
Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual Example – Extending range using WDS One of the most common uses for WDS is to extend the range of the wireless network using repeaters. The diagram above illustrates a simple example where the four Access Points are all at fixed locations (each of the Access Points could, of course, have one or more client/stations connected).
Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual Example - Roaming with WDS Access Points Another common use for WDS is extending the range across a large wireless network but allowing roaming connections between access points or being able to switch to the next Access Point when out of range of the previous Access Point.
