10 Visualizing the Wireless Network Table 73. WLAN Visualization Menu Bar Options Menu Item Edit Graph Delete Graph Image Management View Ungraphed Components AP Power Display Description Opens the window for an existing graph. You can change the background image or graph scale. To change the name of the graph, you must create a new graph. Deletes the active graph. When you select this item, a dialogue box appears to confirm that you want to delete the graph. Lists the available background images and allows you to delete any available image. 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 93 on page 192 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 • Show 802.11 a-Shows the transmit power for all managed APs that have a radio operating in 802.11a mode. • Show 802.11 b/g-Shows the transmit power for all managed APs that have a radio operating in 802.11 b/g 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.
