Cooper Bussmann Wireless Ethernet & Device Server BU-945U-E 802.11 DSSS User Manual

The second diagram shows an existing LAN being extended using BU-945U-Es. In this example, the Access Point is configured at the LAN end - although the wireless link will still work if the Client is at the LAN end.

An Access Point can connect to multiple Clients. In this case, the Access Point should be the “central” unit.

An Access Point could be used as a “Repeater” unit to connect two BU-945U-E Clients, which do not have direct reliable radio paths.

There is no “Special” repeater module, any BU-945U-E can be a repeater and at the same time, can be connected to an Ethernet devices or on a LAN

Multiple Access Points can be set-up in a “mesh” network to provide multiple repeaters.
