Chapter 36 AP Profile Table 189 Configuration > Object > AP Profile > Add/Edit Radio Profile (continued) LABEL A-MPDU Limit A-MPDU Subframe Enable A-MSDU Aggregation A-MSDU Limit RTS/CTS Threshold DESCRIPTION Enter the maximum frame size to be aggregated. Enter the maximum number of frames to be aggregated each time. Select this to enable A-MSDU aggregation. Mac Service Data Unit (MSDU) aggregation collects Ethernet frames without any of their 802.11n headers and wraps the header-less payload in a single 802.11n MAC header. This method is useful for increasing bandwidth throughput. It is also more efficient than A-MPDU except in environments that are prone to high error rates. Enter the maximum frame size to be aggregated. Use RTS/CTS to reduce data collisions on the wireless network if you have wireless clients that are associated with the same AP but out of range of one another. When enabled, a wireless client sends an RTS (Request To Send) and then waits for a CTS (Clear To Send) before it transmits. This stops wireless clients from transmitting packets at the same time (and causing data collisions). Beacon Interval DTIM Output Power A wireless client sends an RTS for all packets larger than the number (of bytes) that you enter here. Set the RTS/CTS equal to or higher than the fragmentation threshold to turn RTS/CTS off. When a wirelessly networked device sends a beacon, it includes with it a beacon interval. This specifies the time period before the device sends the beacon again. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. A high value helps save current consumption of the access point. Delivery Traffic Indication Message (DTIM) is the time period after which broadcast and multicast packets are transmitted to mobile clients in the Active Power Management mode. A high DTIM value can cause clients to lose connectivity with the network. This value can be set from 1 to 255. Set the output power of the AP in this field. If there is a high density of APs in an area, decrease the output power of the NWA5160N to reduce interference with other APs. Select one of the following Max, -3dB (50%), -6dB (25%), -9dB (12.5%), or Min. See the product specifications for more information on your UAG's output power. Enable Signal Threshold Station Signal Threshold Disassociate Station Threshold Allow Station Connection after Multiple Retries Station Retry Count Note: Reducing the output power also reduces the UAG's effective broadcast radius. Select the check box to use the signal threshold to ensure wireless clients receive good throughput. This allows only wireless clients with a strong signal to connect to the AP. Clear the check box to not require wireless clients to have a minimum signal strength to connect to the AP. Set a minimum client signal strength. A wireless client is allowed to connect to the AP only when its signal strength is stronger than the specified threshold. -20 dBm is the strongest signal you can require and -76 is the weakest. Set a minimum kick-off signal strength. When a wireless client's signal strength is lower than the specified threshold, the UAG disconnects the wireless client from the AP. -20 dBm is the strongest signal you can require and -90 is the weakest. Select this option to allow a wireless client to try to associate with the AP again after it is disconnected due to weak signal strength. Set the maximum number of times a wireless client can attempt to re-connect to the AP UAG Series User's Guide 419
