Specify RF Management
RF management optimizes the channel allocation for access points based on clients, user
data traffic, and the nearby RF environment of access points. The wireless controller
periodically checks the radio neighborhood maps and detects changes in the radio
neighborhood maps or loss of connectivity to the wireless controller by an access point.
WLAN healing is a special feature of RF management. When WLAN healing is used, if an
access point goes down or loses connectivity, other access points share its load to avoid a
coverage hole.
To do this, the other access points increase their transmit power. WLAN
healing is configured per security profile group and is active among access points that share
a common security configuration.
You can configure centralized RF management for the basic profile group on the basic RF
Management screen. If you use advanced profile groups, you can use the advanced RF
Management screen to customize settings for each advanced profile group.
WLAN Healing
The wireless controller has the capacity for automatic WLAN healing through the following
features:
• Automatic channel allocation. Allows an access point channel to be distributed
automatically by the wireless controller across the access points on a floor to reduce
interference. Automatic channel allocation considers interference and the traffic load on
the access point, as well as the wireless mode and bandwidth (also referred to as channel
width) to provide the best channel for the access point. For information about how to
configure automatic channel allocation, including the option to skip automatic channel
allocation if there is a heavy traffic load or voice activity, see Configure Channels on
page 137.
• Automatic transmission power.
Automatically determines the optimum transmit power
of an access point based on the coverage requirement.
The access point scans its
neighborhood to determine the RF environment to minimize neighboring access point
interference, leakage across floors, and coverage holes.
When you configure WLAN healing, NETGEAR recommends the following:
• Configure the WLAN self-healing wait time to a value greater than the access point reboot
time, which is usually one minute. This allows for fluctuations in the power of nearby
access points when access points are rebooted.
• The number of neighbors to participate in WLAN self-healing should not be very large
(three to four usually suffices in most deployments).
This avoids too many access points
increasing power for a single failed access point.
