Chapter 8 Wireless Configuration Table 25 Wireless: AP + Bridge LABEL DESCRIPTIONS RTS/CTS Threshold 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). Fragmentation Threshold 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. The threshold (number of bytes) for the fragmentation boundary for directed messages. It is the maximum data fragment size that can be sent. Enter an even number between 256 and 2346. 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. This value can be set from 30ms to 1000ms. 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 100. Set the output power of the NWA in this field. If there is a high density of APs in an area, decrease the output power of the NWA to reduce interference with other APs. Select from 100% (Full Power), 50%, 25%, 12.5% and Minimum. See the product specifications for more information on your NWA's output power. SSID Profile Note: Reducing the output power also reduces the NWA's effective broadcast radius. The SSID (Service Set IDentifier) identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same SSID. Select an SSID Profile from the drop-down list box. Configure SSID profiles in the SSID screen (see Section 9.2 on page 147 for information on configuring SSID). If you are configuring the NWA from a computer connected to the wireless LAN and you change the NWA's SSID or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NWA's new settings. NWA-3500/NWA-3550 User's Guide 133
