Collocation

How many DWL-1800B or DWL-1800R units can be collocated on the same building or tower?

You can collocate up to 3 DWL-1800B or DWL-1800R units on the same structure. Each unit is assigned to one of the non-overlapping channels, 1, 6, or 11.

Can a Frequency Hopping network operate in the same area as the D-Link Air Premier DWL-1800?

Yes, but in a collocated network both products will suffer some a decrease in performance. The degree of performance loss depends on network utilization. For example, the higher the utilization of the Frequency Hopping network, the higher the level of impact on the Direct Sequence (DWL-1800) network, and vice versa. Typically, in light to moderately utilized networks, the performance loss is not significant.

Can I use D-Link Air Premier DWL-1800 Bridges to feed a Frequency Hopping distribution point?

Yes, bandwidth sharing between the Direct Sequence and Frequency Hopping products can be minimized if the network is designed using cross-polarized directional antennas with as much spatial separation as possible. Contact technical support for more information.
