General
The
BreezeNET DS.5800 Wireless Base Unit
(BU-DS.5800) and
Wireless Remote Bridge
(RB-DS.5800) are designed to provide longrange point-to-multipoint links for outdoor applications. The products use direct sequence spread spectrum radio technology operating at the frequency range of 5.725 – 5.850 GHz, a part of the FCC's unlicensed
Industrial, Scientific, Medical (ISM) band. Data is transmitted at rates of up to 11 Mbps, providing network users with full 10BaseT Ethernet speeds.
BreezeNET DS.5800 Compatibility and Standards
BreezeNET DS.5800 products are compatible with the following standards.
!
IEEE 802.3 10BaseT Ethernet.
!
DHCP for automatic IP address assignment.
!
SNMP for system management.

System Description
BreezeNET DS.5800
Functional Description
The BreezeNET BU-DS.5800 and RB-DS.5800 can be used as highspeed connections between two or more remote networks.

BU-DS.5800 Wireless Base Unit
The BU-DS.5800 connects one or more remote sites to a central server or Internet connection. In a point-to-multi-point configuration the BU-
DS.5800 is the central unit while in point-to-point configurations it should be installed at one end of the link.
The BU-DS.5800 is available in two options: The BU-DS.5800 and the
BU-DS.5800D.

BreezeNET DS.5800 System Manual
The BU-DS.5800 is the basic unit, equipped with an antenna integrated into the front cover of the outdoor unit.
The BU-DS.5800D doesn’t have an integral antenna and is equipped with a connector (on the outdoor unit) for an external antenna (not included with the unit). A protective sun cover is supplied and should
be mounted on the front of the outdoor unit. Refer to “Antennas for
Outdoor Applications” on page 2-6 for information on how to select an
appropriate external antenna.
RB-DS.5800 Wireless Bridge
The RB-DS.5800 Wireless Bridge connects a remote Ethernet network to a central network server or Internet site via a BU-DS.5800 Multipoint
Base Unit.
The maximum number of MAC addresses that the unit can handle at any specific time is 1024 and the Aging algorithm is applied at all times.
When a station on the Ethernet LAN sends a message that is not destined for a local station, the RB-DS.5800 forwards the message to the BU-DS.5800. When the BU-DS.5800 receives a message destined for a station on the RB-DS.5800's LAN, the BU-DS.5800 forwards it to the RB-DS.5800. In this manner, the RB-DS.5800 and the BU-DS.5800 work together like a standard network bridge.
The first time each station on the RB-DS.5800’s LAN sends a message, the station’s address is registered by both the RB-DS.5800 and the BU-
DS.5800. It is possible for the RB-DS.5800 and BU-DS.5800 to store all the addresses necessary to support an entire LAN connected to a RB-
DS.5800.
The RB-DS.5800 comes in two options: The RB-DS.5800 and the RB-
DS.5800D.
The RB-DS.5800 is the basic unit, equipped with an antenna integrated into the front cover of the outdoor unit.
The RB-DS.5800D has no integral antenna and is equipped with an antenna connector (on the outdoor unit) for the connection of an external antenna (not included with the unit). When this unit is ordered, a protective sun cover is supplied with the unit and should be mounted
on the front of the outdoor unit. Refer to “Antennas for Outdoor
Applications” on page 2-6 for information on how to select an external
antenna.
