Chapter 34 Object Table 264 Configuration > Object > AP Profile > Add/Edit Radio Profile (continued) LABEL DESCRIPTION 2.4 GHz Channel Selection Method This field is available when you set Channel Selection to DCS. Select auto to have the AP search for available channels automatically in the 2.4 GHz band. The available channels vary depending on what you select in the 2.4 GHz Channel Deployment field. Channel ID Select manual and specify the channels the AP uses in the 2.4 GHz band. This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel Selection Method to manual. Time Interval DCS Time Interval Schedule Start Time Week Days 2.4 GHz Channel Deployment Select the check boxes of the channels that you want the AP to use. Select this option to have the AP survey the other APs within its broadcast radius at the end of the specified time interval. This field is available when you set Channel Selection to DCS. Enter a number of minutes. This regulates how often the AP surveys the other APs within its broadcast radius. If the channel on which it is currently broadcasting suddenly comes into use by another AP, the AP will then dynamically select the next available clean channel or a channel with lower interference. Select this option to have the AP survey the other APs within its broadcast radius at a specific time on selected days of the week. Specify the time of the day (in 24-hour format) to have the AP use DCS to automatically scan and find a less-used channel. Select each day of the week to have the AP use DCS to automatically scan and find a lessused channel. This field is available only when you set Channel Selection to DCS and set 2.4 GHz Channel Selection Method to auto. Select Three-Channel Deployment to limit channel switching to channels 1,6, and 11, the three channels that are sufficiently attenuated to have almost no impact on one another. In other words, this allows you to minimize channel interference by limiting channelhopping to these three "safe" channels. Select Four-Channel Deployment to limit channel switching to four channels. Depending on the country domain, if the only allowable channels are 1-11 then the Zyxel Device uses channels 1, 4, 7, 11 in this configuration; otherwise, the Zyxel Device uses channels 1, 5, 9, 13 in this configuration. Four channel deployment expands your pool of possible channels while keeping the channel interference to a minimum. Note: For US and Canada models, country code is fixed to US or Canada respectively and is not user selectable. Enable 5 GHz DFS Aware This field is available only when you select 11a, 11a/n or 11ac in the 802.11 Band field. Select this if your APs are operating in an area known to have RADAR devices. This allows the device to downgrade its frequency to below 5 GHz in the event a RADAR signal is detected, thus preventing it from interfering with that signal. 5 GHz Channel Selection Method Advanced Settings Enabling this forces the AP to select a non-DFS channel. This shows auto and allows the AP to search for available channels automatically in the 5 GHz band. ZyWALL ATP Series User's Guide 667
