General
Can the BU-DS.11/RB-DS.11D indoor unit be placed outdoors?
It is not recommended. The BU-DS.11/RB-DS.11 indoor units are specified to
operate between 0°C and 40°C and is not weather protected. Therefore, if it is
necessary to install it outdoors, it should be placed in a protective cabinet.
Do DS.11 units support 802.1Q VLAN?
The DS.11 passes VLAN packets transparently within a VLAN network without
taking any action on 802.1Q frames.
What is the maximum number of networked PCs the BU-DS.11/RB-DS.11 can
learn?
The DS.11 units can learn up to 1024 network MAC addresses from the LAN side.
Can the BU-DS.11/RB-DS.11 be used for multi-point as well as point-to-point
links?
The BU-DS.11 can support multiple RB-DS.11 units creating a point-to-multi-
point network.
How many RB-DS.11 units can one BU-DS.11 support?
The maximum number of associations is 128.
What is the practical limit to the number of RB-DS.11 units per BU-DS.11?
And, what performance can I expect for a multi-point link?
This depends upon expected average throughput at peak traffic hours. 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.11’s would be the limit. For a moderately
utilized network needing about 175Kbps to 258Kbps average, 18 to 24 RB-DS.11’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.11’s.
What is the range of the BU-DS.11/RB-DS.11 Bridges?
A range of 25 km/15 miles (FCC) or 10 km/6 miles (ETSI) can be achieved using
the UNI-24 antenna kit for a point-to-point link. Consult the antenna and
accessory guide range tables for distances using other antennas.
Does the BU-DS.11/RB-DS.11D support 802.1d spanning tree protocol?
The BU-DS.11/RB-DS.11 does not support spanning tree.
