Specifying RF Management

You can configure centralized RF management in the Basic RF Management screen. If you
use access point groups, you can use the Advanced RF Management screen to customize
settings for each group. RF management optimizes the channel allocation for access points
based on clients, user data traffic, and observed 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 controller by an access
point. 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 runs
between the access points sharing common security configuration.
The wireless controller has the capacity for automatic WLAN healing through the following
features:
• Auto 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. Auto
channel allocation takes into consideration the floor plan, interference, traffic load on the
access point, and neighborhood floor maps, as well as the wireless mode and bandwidth
Description
You should leave this check box selected during normal operation.
Automatic channel allocation distributes channels across the managed
access points to reduce interference.
• You can specify the wireless band by selecting the 2.4 GHz or 5 GHz
check box.
• You can remove one or more channels from the list of available channels
by clearing its check box. This is a good way to avoid interference with
competing equipment such as in a medical setting where medical
devices use a specific channel.
• You cannot add channels. The wireless controller determines available
channels based on the Country/Region that you specified in the
General Settings screen.
You can select the Active voice call and High Traffic Load check boxes to
prevent channel changes during voice calls or high traffic.
If the wireless controller is prevented from reallocating a channel because it
is in use, wireless controller checks again at the next scheduled channel
allocation.
Specify the Run channel allocation at and Run channel allocation every
settings. NETGEAR recommends that you schedule channel allocation
once a day at times when the least number of clients are expected to be
connected.
Run the channel allocation immediately and apply the selected channels to
connected managed access points.
