About the Radios
The AT-WA7500 and AT-WA7501 access products may contain one or
two radios. You can use access points that contain two different types of
radios to support two different types of wireless networks, such as legacy
networks. You can use access points with two of the same type of radios
as WAPs, as point-to-multipoint bridges, to increase throughput in a busy
network, or to provide redundancy.
Currently, you cannot have two 802.11g radios or have one 802.11g radio
and one 802.11b radio in the access points.
The 802.11g radio is sometimes referred to as the 802.11b/g radio
because it can be configured to communicate with any 802.11b and
802.11g radios that have the same SSID and security settings.
The next sections explain how to configure the radios that are in your
access point. Only the radios actually installed in your access point appear
in the configuration menus.
