D-Link Unified Access System Software User Manual 12/10/09 Table 342: WLAN Visualization Menu Bar Options (Cont.) Menu Item Ungraphed Components AP Power Display Show Managed APs Show RF Scan APs Show Managed AP Clients Images Channel Color Help Allows you to change the view of the ungraphed components in the panel on the left: • Tab View: Shows one type of component at a time, organized by tabs. • List View: Shows all three types of components in the left panel. Figure 369 on page 534 shows the difference between the tab view and list view. Select the power range image to display for a managed AP: • Disable Power Display: The power range image is not displayed • 5 GHz Band: Shows the transmit power for all managed APs that have a radio operating in 802.11a or 5-GHz 802.11n mode. • 2.4 GHz Band: Shows the transmit power for all managed APs that have a radio operating in 802.11 b/g or 2.4 GHZ 802.11n mode. The size of the power range image is based on the transmit power for the radio, which can be low, medium, or high. The size of the power range image also depends on the actual scale factor of the current background image. If the AP has two radios that are configured in the same mode, two power range images are displayed. Note: The color of the power range image is based on the assigned channel of the associated radio. If two APs use the same channel (or channels that are close together) and are within each other's transmission range, the APs will interfere with each other and wireless clients will experience poor WLAN performance. To reduce interference, you can take one of the following steps: • Reduce the transmit power on the APs. • Physically place the APs further apart. • Use the automatic channel adjustment algorithm on the APs or statically set the channels so they are non-interfering channels. CAUTION: Power ranges are for illustrative purposes only. The actual power distribution varies based on factors such as office wall propagation and background RF noise. Options Controls whether to display AP on the graph. Clearing the check box hides but does not un-graph the objects. Controls whether to display the APs detected through the RF scan. Clearing the check box hides but does not un-graph the objects. Controls whether to display wireless clients associated with managed APs. Clearing the check box hides but does not un-graph the objects. Legend Shows the icons associated with each WLAN component on the graph. Maps the color of the power transmission image to the channel that the radio is using for transmission. Help Opens a new HTML window to display the WLAN Visualization online help page. Legend Menu The items in the Legend menu contain information about the icons and colors that appear on the graph. Page 536 Visualizing the Wireless Network Document 34CSFP6XXUWS-SWUM100-D7
