D-Link user manual Does the DWL-1800B supports 802.1d spanning tree protocol?

Page 55

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 DWL-1800B supports 802.1d spanning tree protocol?

No, the DWL-1800B/DWL-1800R does not support spanning tree.

What is the normal PER (Packet Error Rate) for the DWL-1800B/DWL-1800R?

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 DWL-1800?

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 D-Link Air Premier DWL-1800 compatible with other D-Link wireless 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 DWL-1800B/DWL-1800R can operate at 1, 2Mbps 5.5Mbps and 11Mbps with D-Link Air and Air Plus wireless family products. D-Link Air Premier DWL-1800 units are fully WI-FI compliant.
