ProSafe 20-AP Wireless Controller WC7520 Reference Manual Table 18. Channel Allocation Setting Automatic channel allocation Valid corporate channels Prevent channel change during Schedule channel allocation Run Now button 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. 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 Chapter 7: Configuring Wireless Settings | 75
