Chapter 22 Dynamic Channel Selection In this example, if the NWA attempts to broadcast on channels 1, 6, or 11 it is met with cross-channel interference from the other AP that shares the channel. This can result in noticeably slower data transfer rates, the dropping of the connection altogether, or even lost data packets. However, if the NWA broadcasts on the otherwise empty channel 4 then there will be minimal interference and a clearer connection to the network. To alleviate this problem of having to manually change channels every time interference crops up, you would normally need to scan the area quite often to see which channels are currently unused then set your device to use one of them. But with Dynamic Channel Selection, the NWA does this automatically. 22.2 The DCS Screen Use this screen to configure your Dynamic Channel Selection options . Click DCS in the navigation menu.

Figure 167 DCS The following table describes the labels in this screen Table 82 DCS FIELD Dynamic Channel Selection DCS Time Interval DESCRIPTION Select this to either Enable or Disable dynamic channel selection. Enter a number of minutes. This regulates how often the NWA 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 NWA will then dynamically select the next available empty channel or a channel with markedly lower interference. This is set to 720 minutes by default. 276 NWA-3160 Series User's Guide
