BreezeNET DS.11 Series User’s Guide
A-4
What is the normal PER (Packet Error Rate) for the BU-
DS.11/RB-DS.11?
The error rate will be about 4%-6% (transmitted fragments vs.
retry count). This is typical when operating in a non-interference
environment at maximum range for bi-directional traffic loads. If
the traffic load is more uni-directional, then the PER will be less.
What is the best value for the CW min parameter on the
DS.11?
Setting the CW min parameter to 31 for heavy bi-directional
traffic loads will minimize the PER. Setting the CW min to 15
will improve performance for more uni-directional traffic
loads. CW min 7 should only be used for short-range point-
to-point links, and 63 should be used for large, long-range
multi-point links.
Is the DS.11 compatible with other DS equipment from
other vendors?
Yes. However, for the outdoor bridges, interoperability can vary
from vendor to vendor and in some cases it may not operate if
the manufacturer’s implementation is not pure 802.11b. The
BU-DS.11/RB-DS.11 can operate at 1 and 2Mbps with legacy
802.11b DS equipment, and at 5.5Mbps and 11Mbps with
802.11b High Rate DS equipment. BreezeNET DS.11 units are
fully WI-FI compliant.
