DS.11 FAQ
A-3
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 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.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?
15 miles/24Km (FCC) or 10 KM (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?
No, the BU-DS.11/RB-DS.11 does not support spanning
tree.
