This installation scenario describes one layer of bridging with one Root-Bridge
and one Child Bridge. This scenario is common, for example, in schools or
universities where students or professionals in remote buildings need secure,
high-bandwidth 802.11b or 802.11g access to the network.
In this configuration, an AP8250 or AP7250 is placed on the network and an AP8250
with the 802.11g Upgrade Kit is placed at each of the desired remote locations.
The access point at the center of the network is configured as the
Root Bridge
with an omnidirectional antenna.
The remote bridges are configured as
Child Bridges
and use an 8 dBi
directional antenna (3CWE495), which is aimed at the Root-Bridge.
.
Because the WDS radio and the local access point radio are operating in
approximately the same frequency range, the following guidelines must be
followed for successful installation:
The WDS link should be configured on Channel 2 or Channel 10.
The access point radio should be configured on the other Channel.
The directional antenna for the WDS link must be located at least three feet
from the AP8250 and aimed away from the AP8250.
The radio that is using the external antenna must be configured to transmit
from the appropriate antenna connector (this is configured on the
Radio Settings page in the Configuration Management System).
