DS.5800 FAQ
General
Can the BU-DS.5800/RB-DS.5800D indoor unit be placed outdoors?
It is not recommended. The BU-DS.5800/RB-DS.5800 indoor units are
specified to operate between 0°C and 40°C and is not weather proof so it
is best to mount the DS.5800 indoors or in a protective cabinet.
Do DS.5800 units support 802.1Q VLAN?
Yes, but the support is limited to transparent operation. This means
that the DS.5800 does not take any action on 802.1Q frames, but will
transparently pass them within a VLAN network.
What is the maximum number of networked PCs the BU-DS.5800/
RB-DS.5800 can learn?
1024 network MAC addresses can be learned by the BU-DS.5800/RB-
DS.5800 from the LAN side.
Can the BU-DS.5800/RB-DS.5800 be used for multi-point as well as
point-to-point links?
Yes. The BU-DS.5800 can support multiple RB-DS.5800 units creating
a point-to-multi-point network.
How many RB-DS.5800 units can one BU-DS.5800 support?
The maximum number of associations is 128.
What is the practical limit to the number of RB-DS.5800 units per
BU-DS.5800? And, what performance can I expect for a multi-point
link?
This depends upon average throughput expectations. All clients would
have the maximum throughput available for burst traffic, however the
overall average would depend on the utilization of the network. For
example, in a heavily utilized network needing about 350Kbps to
500kbps average net throughput per site, 9 to 12 RB-DS.5800’s would
be the limit. For a moderately utilized network needing about 175Kbps
to 258Kbps average, 18 to 24 RB-DS.5800’s should be used, and for a
lightly used network needing 32Kbps to 48Kbps average net throughput
per site could use up to 128 RB-DS.5800’s.
What is the range of the BU-DS.5800/RB-DS.5800 Bridges?
Up to 30 miles (50Km) can be achieved using the SP2-5 2 ft. Parabolic
antenna kit for a point-to-point link. Consult the antenna and accessory
guide range tables for distances using other antennas.
