Netgear WC7600v2 – ProSAFE Wireless Controller 사용자 설명서

Radio frequency (RF) management lets you specify the transmission power settings, WLAN 
healing settings, and band steering settings.

Radio frequency (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 you use WLAN healing, if an 
access point goes down or loses connectivity, other access points share its load to avoid a 
coverage hole. In such a situation, 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 page. If you use advanced profile groups, you can use the advanced RF 
Management page to customize settings for each advanced profile group. 

The wireless controller supports automatic WLAN healing through the following features:

Automatic channel allocation. Enables the wireless controller to distribute an access 
point channel automatically 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 
during a heavy traffic load or voice activity, see 

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, we recommend the following:

Configure the WLAN self-healing wait time to a value greater than the access point reboot 
time, which is usually one minute. Set an appropriate wait time to allow for fluctuations in 
the power of nearby access points when access points are rebooted.

The number of neighbors to participate in WLAN self-healing must not be large (three to 
four usually suffices in most deployments). Keep the number of participants low to 
prevent too many access points from increasing power for a single failed access point.
