APPENDIX C. DS.11 FAQ
How many BU-DS.11 or RB-DS.11 units can be co-located on the same building top or tower?
You can co-locate up to 3 BU-DS.11 or RB-DS.11 units on the same structure. Each unit is
assigned to one of the non-overlapping channels, 1, 6, or 11.
What is the antenna separation requirement for co-locating
BU-DS.11
or RB-DS.11 units on the same
building top or tower?
The antennas should be mounted at least 2 feet apart when using UNI-16’s, 15 feet when using UNI-
24’s, and 75 feet when using OMNI-8’s. For omni antennas, the maximum link distance is reduced
by up to 50%. Greater separation will improve the link distance.
Can my FH network operate in the same area as the DS?
Yes, in a co-located network, both products will suffer some loss in performance. This depends on
network utilization. For example, the higher the utilization of the FH network, the higher the level
of impact on the DS network, and visa versa. Typically, in light to moderate utilized networks, the
performance loss is not perceivable.
Can I use DS.11 Bridges to feed a FH distribution point?
Yes, bandwidth sharing between the DS and FH products can be minimized if the network is
designed using cross polarized directional antennas, and as much spatial separation as possible.
Contact technical support for assistance with this.
What is the throughput of the DS.11?
The BU-DS.11/RB-DS.11 bridge link typical performance is 4.2Mbps using TCP and 6.2Mbps
using UDP. For long range links, the performance will drop about 5%.
