5 Managing the Access Point Table 16. Radio Settings Field RTS Threshold Maximum Stations Transmit Power Rate Sets Description Specify an RTS Threshold value between 0 and 2347. The RTS threshold specifies the packet size of the minimum packet for which a request to send (RTS) frame will be sent. This helps control traffic flow through the access point, especially one with a lot of clients. If you specify a low threshold value, RTS packets will be sent more frequently. This will consume more bandwidth and reduce the throughput of the packet. On the other hand, sending more RTS packets can help the network recover from interference or collisions which might occur on a busy network, or on a network experiencing electromagnetic interference. Specify the maximum number of stations allowed to associate to this radio at any one time. You can enter a value between 0 and 256. Enter a percentage value for the transmit power level for this access point. The default value, which is 100%, can be more cost-efficient than a lower percentage since it gives the access point a maximum broadcast range and reduces the number of APs needed. To increase capacity of the network, place APs closer together and reduce the value of the transmit power. This helps reduce overlap and interference among APs. A lower transmit power setting can also keep your network more secure because weaker wireless signals are less likely to propagate outside of the physical location of your network. Check the transmission rate sets you want the access point to support and the basic rate sets you want the access point to advertise: • Rates are expressed in megabits per second. • Supported Rate Sets indicate rates that the access point supports. You can check multiple rates (click an option to select or de-select a rate). The AP will automatically choose the most efficient rate based on factors like error rates and distance of client stations from the AP. • Basic Rate Sets indicate rates that the access point will advertise to the network for the purposes of setting up communication with other APs and client stations on the network. It is generally more efficient to have an AP broadcast a subset of its supported rate sets. For the DWL-8500AP, use the Radio Settings page to configure both Radio One and Radio Two. The settings on the page apply only to the radio that you select from the Radio list. After you configure settings for one of the radios, click Update and then select and configure the other radio. Be sure to click Update to apply the second set of configuration settings for the other radio. Configuring Radio Settings 61
