AT-WA7500 and AT-WA7501 Installation and User’s Guide
37
Allied Telesyn recommends that you always implement some type of
security.
Using Dual Radio
Access Points for
Redundancy
You can configure AT-WA7500 units and AT-WA7501 units that have two
802.11g radios, two 802.11b radios, or two 802.11a radios to provide
redundancy for your network.
Note
Currently, the AT-WA7500 and AT-WA7501 do not support two
802.11g radios.
During normal operations, end devices send frames to the master radio in
one of the access points, which bridges the frames to the wired network. If
a section of the wired network goes down, the master radio receives the
frames, and then the station radio forwards the frames to a master radio in
another access point that is within range.
In each access point, you need to configure one radio’s node type as a
Master, which communicates with the wireless end devices, and configure
the other radio’s node type as a Station, which communicates to another
access point with a master radio and within range.
