Chapter 36 AP Profile The following table describes the labels in this screen. Table 189 Configuration > Object > AP Profile > Add/Edit Radio Profile LABEL Hide / Show Advanced Settings Create New Object General Settings Activate Profile Name 802.11 Band DESCRIPTION Click this to hide or show the Advanced Settings in this window. Select an item from this menu to create a new object of that type. Any objects created in this way are automatically linked to this radio profile. Select this option to make this profile active. Enter up to 31 alphanumeric characters to be used as this profile's name. Underscores are allowed. Select the wireless band which this radio profile should use. 2.4 GHz is the frequency used by IEEE 802.11b/g/n wireless clients. Mode 5 GHz is the frequency used by IEEE 802.11a/n wireless clients. Select how to let wireless clients connect to the AP. When using the 2.4 GHz band, select b/g to let IEEE 802.11b and IEEE 802.11g compliant WLAN devices associate with the AP. When using the 2.4 GHz band, select b/g/n to let IEEE 802.11b, IEEE 802.11g, and IEEE 802.11n compliant WLAN devices associate with the AP. When using the 5 GHz band, select a to let only IEEE 802.11a compliant WLAN devices associate with the AP. Channel When using the 5 GHz band, select a/n to let IEEE 802.11a and IEEE 802.11n compliant WLAN devices associate with the AP. Select the wireless channel which this radio profile should use. It is recommended that you choose the channel least in use by other APs in the region where this profile will be implemented. This will reduce the amount of interference between wireless clients and the AP to which this profile is assigned. Schedule Advanced Settings Channel Width Some 5 GHz channels include the label indoor use only. These are for use with an indoor AP only. Do not use them with an outdoor AP. Select a schedule to control when the WLAN of the managed AP (to which this radio profile is applied) is turned on. Otherwise, select none and the managed AP's WLAN is always enabled. Select the channel bandwidth you want to use for your wireless network. Select Auto to allow the UAG to adjust the channel bandwidth to 40 MHz or 20 MHz depending on network conditions. Guard Interval Select 20 MHz if you want to lessen radio interference with other wireless devices in your neighborhood. Set the guard interval for this radio profile to either short or long. Enable A-MPDU Aggregation The guard interval is the gap introduced between data transmission from users in order to reduce interference. Reducing the interval increases data transfer rates but also increases interference. Increasing the interval reduces data transfer rates but also reduces interference. Select this to enable A-MPDU aggregation. Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their 802.11n headers and wraps them in a 802.11n MAC header. This method is useful for increasing bandwidth throughput in environments that are prone to high error rates. UAG Series User's Guide 418
