D-Link Unified Access System User Manual Table 9. Radio Settings Field Station Isolation Rate Sets Basic Supported Mode Maximum Clients DTIM Period Description Select the check box to enable station isolation, or clear it to disable station isolation. • Enabled: Access point blocks communication between wireless clients. The access point still allows data traffic between its wireless clients and wired devices on the network, but not among wireless clients. • Disabled: wireless clients can communicate with one another normally by sending traffic through the access point. 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. These numbers 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. These numbers indicate rates that the access point supports. You can check multiple rates (click a check box to select or de-select a rate). The AP automatically chooses the most efficient rate based on factors like error rates and distance of client stations from the AP. The Mode defines the Physical Layer (PHY) standard the radio uses. The DWL-3500AP and Radio 1 on the DWL-8500AP use the IEEE 802.11g mode PHY standard. This mode is a higher speed extension (up to 54 Mbps) to the 802.11b PHY, while operating in the 2.4 GHz band. It uses orthogonal frequency division multiplexing (OFDM). It supports data rates ranging from 1 to 54 Mbps. IEEE 802.11b clients can use the 802.11g mode. Radio 2 on the DWL-8500AP use the IEEE 802.11a mode, which is a PHY standard that specifies operating in the 5 GHz U-NII band using orthogonal frequency division multiplexing (OFDM). It supports data rates ranging from 6 to 54 Mbps. If the radio state is disabled, the mode displays as Off. Specify the maximum number of stations allowed to access this access point at any one time. You can enter a value between 0 and 256. The Delivery Traffic Information Map (DTIM) message is an element included in some beacon frames. It indicates which client stations, currently sleeping in low-power mode, have data buffered on the access point awaiting pick-up. The DTIM period you specify indicates how often the clients served by this access point should check for buffered data still on the AP awaiting pickup. Specify a DTIM period within the given range (1 - 255). The measurement is in beacons. For example, if you set this field to "1" clients will check for buffered data on the AP at every beacon. If you set this field to 10, clients will check on every 10th beacon. 90 © 2001- 2008 D-Link Corporation. All Rights Reserved.
