BU
-DS.11 Wireless Base Station
The BU-DS.11 is an IEEE 802.11 TGb-compliant base station bridge that is used to connect either a
single remote site or multiple remote sites to a central server or Internet connection. It is the
central unit for a multipoint configuration and always one side of a point-to-point configuration.
The BU-DS.11 comes in two options: the basic unit comes with an antenna integrated on the front
cover of the Outdoor unit. In this model, the front cover also functions as a protective sun cover.
In BU-DS.11D models with no integral antenna, the unit is provided with two antenna connectors
(on the Outdoor unit) for connection of one or two external antennas. Refer to Section Sections
2.6.4 and 2.6.12 for information on how to select external antennas. When two antennas are
connected to the Outdoor unit, the unit supports the antenna diversity feature described in Section
2.6.6.
RB
-DS.11 Wireless Bridge Client
The RB-DS.11 connects a remote Ethernet network to a BU-DS.11 Multipoint Base Station bridge
located at a central server or Internet site. It can be programmed to handle up to 1024 MAC
addresses.
When a station on the Ethernet LAN sends a message that is not destined for a local station, the RB-
DS.11 wirelessly forwards the message to the BU-DS.11. When the BU-DS.11 receives a message
destined for a station on the RB-DS.11's LAN, the BU-DS.11 wirelessly forwards it to the RB-
DS.11. In this manner, the RB-DS.11 and the BU-DS.11 work together like a standard network
bridge.
The first time each station on the RB-DS.11’s LAN sends a message, the station’s address is
registered in the RB-DS.11 and the BU-DS.11. The RB-DS.11 and BU-DS.11 can hold all the
addresses necessary to support an entire LAN connected to a RB-DS.11.
