Placing and Configuring Virtual APs

To place an AP on the floor plan, press the AP drawing tool button and select one of the pre-defined AP types; for example “Generic 802.11n (2.4 GHz)” or “Generic dual band 802.11n.” Click on the floor plan to place an AP in a desired location. After that you can change its properties by double-clicking on the AP or by selecting the Properties context menu item. The AP Properties dialog can be used for loading AP characteristics from one the presets, assigning a unique name to the AP, or for customizing AP characteristics. Virtual AP icons are marked with a small blue “V” in the icon corner so that you could distinguish between real and virtual APs.

To customize an AP, you can use two tabs: one for the 2.4 GHz Radio and one for the 5 GHz Radio. These tabs allow you to turn on and off these radios independently (using the Radio enabled check box) and configure the following characteristics for each of the two radios:

· Standard. Use this drop-down list to select one of the 802.11 standards. For the 2.4 GHz band, select 802.11n or one of the legacy standards. For the 5 GHz band, select 802.11ac, 802.11n, or one of the legacy standards. Remember that 802.11ac can be used only in the 5 GHz band.
· Channel width. If the selected standard allows channel bonding, then select one of the available channel widths: up to 40 MHz for 802.11n and up to 160 MHz for 802.11ac.
· Channel / Channel set. Select a single channel if the channel width is set to 20 MHz or a set of channels if the channel width is greater than 20 MHz.
· MAC address. You can change the MAC address to your AP. This is typically not necessary because the application always assigns unique MAC addresses to the APs.
· SSID. Use this field to assign an SSID to the AP. The same SSID may be shared by several APs.
· Power. Use this drop-down list to select the AP transmit power. Most of APs have a transmit power of 17 dBm (50 mW). It is always a good idea to refer to the documentation of the specific AP model you plan to deploy to find this value. Remember that transmit power might depend on the channel frequency and band.
· HT / VHT Parameters. Use this frame to control the advanced 802.11n (HT) or 802.11ac (VHT) parameters: primary channel number, number of spatial streams, short guard interval, and supported rates. The Supported Rates dialog can be used to specify the legacy and HT /VHT rates supported by the AP. It is a common practice to disable some or all of the legacy rates when you plan a WLAN for performance rather than coverage.
· Antenna settings. Use this frame to specify the kind of antenna used by the AP. You can choose one of the antenna models by major Wi-Fi equipment vendors or one of the generic antenna types. With the Rotation control, you can specify the angle (in degrees) relating to the horizontal positioning of the antenna. With the Elevation control, you can specify the angle (in degrees) above the horizon, i.e., the angle by which the antenna is tilted up or down in relation to the theoretical horizon. With the Tilt control, you can specify the angle (in degrees) relating to the vertical axis, i.e., the angle by which the antenna is tilted sideways. The Height control can be used to specify the height of the AP above the floor level. The Advanced dialog provides top, front, right, and 3D views of the selected antenna diagram and can be used to adjust the antenna orientation either by rotating the diagram top, front, or right views or by entering numeric values.

When you have edited AP properties, you can save the current configuration for future use by clicking the Save as Preset button at the bottom of the dialog window.
