User's Guide C-4 BreezeNET BU-DS.11/RB-DS.11
What is the maximum number of networked PC’s the BU-DS.11/RB-DS.11 can learn?
1024 network MAC addresses can be learned by the BU-DS.11/RB-DS.11.
Can the BU-DS.11/RB-DS.11 be used for multi-point as well as point to point links?
Yes. The BU-DS.11 can support multiple RB-DS.11 units creating a 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 client bridges per BU-DS.11? And, what performance can I
expect for a multi-point link?
This really depends on 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 or 24Km can be achieved using the UNI-24 antenna kits for a point to point link. Consult
the antenna and accessory guide range tables for distances using other antenna combinations.
What is the power supply ratings for the DS.11?
The DS.11 power supply is rated for 100 – 240VAC input (47-63Hz) and 9VDC at 1.67A output.
Polarity doesn’t matter.
Can I use the same antenna systems and accessories on my DS.11 as on my PRO.11?
Yes. The RF connector on the DS.11 is the same unique SMA type as used on the PRO.11, so all the
same antennas and cables can be used.
What management options are available on DS.11?
The BU-DS.11/RB-DS.11 DS.11 comes with a graphical management utility that operates on any
Windows based network ready PC. With this utility you can configure and monitor every DS.11 on
your network. You can also use the DS.11 SNMP MIB on standard management platforms like
SNMPc, and HP Openview.
Does the DS.11 offer out-of-band management?
No, the DS.11 does not offer out-of-band management, such as a serial port. The DS.11 is managed
in-band only via the DS.11 manager utility or SNMP.
Can I use the AMP250 or AMP500 on the DS.11?
No. The AMP250/500 products are not tested or certified for use with the DS.11 products.
What installation and site survey tools are available for BU-DS.11/RB-DS.11?
