WDS settings
The R110/R120 supports WDS (Wireless Distribution System). WDS enables one or more
access points to rebroadcast received signals to extend the range and reach of the wireless
network, although this can affect the overall throughput of data.
Note that WDS implementations can vary from product to product. Hence, there is no
guarantee that different products will interoperate. In addition, the security settings for WDS
links are the same as those set up for your wireless clients.
Key concepts
WDS links provide an effective solution for extending network coverage in situations where it is
impractical or expensive to run cabling. Each R110/R120 can create one WDS link on each
VAP interface, or up to four WDS links per radio. For example, in the following figure, R110/
R120 #1 and R110/R120 #2 use the WDS on one VAP interface to create a wireless link
between the main office network and a small network in a warehouse, while also supporting
local wireless communities on another VAP interface:
Simultaneous AP and WDS support
The R110/R120 simultaneously supports wireless communities and one or more WDS links.
Although this offers flexibility, note that the total available bandwidth on the radio is shared
between all WDS links and wireless users. This can result in reduced throughput if high volumes
of traffic are being sent by both wireless users and the WDS links.
Using the 5 GHz band for WDS links
When the R110/R120 uses WDS only to extend the network by providing a dedicated link to
another R110/R120 (that is, it does not simultaneously provide a wireless network for wireless
clients), HP recommends that, whenever possible, the WDS links use 802.11a, 802.11n, or
802.11ac in the 5 GHz band. This optimizes throughput and reduces the potential for
interference, as follows:
•
Most Wi-Fi clients support 802.11b/g/n in the 2.4 GHz band, this frees the 5 GHz band
for other applications such as WDS.
