Allied Telesyn recommends that you always implement some type of
security.
Using Dual Radio
Access Points for
Redundancy
You can configure the AT-WA7500 that has two 802.11b radios or two
802.11a radios to provide redundancy for your network. 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.
In this example, AP3 is a dual radio access point. It may be located on a
loading dock or other remote location. During normal operations, AP3
functions as a normal access point, transmitting frames to and from the
host. However, if the Ethernet connection is disrupted, AP3 can function as
a WAP and continue operations by transmitting frames to a master radio
in AP1. AP3 must be within range of AP1.
To install dual radio access points for redundancy
