The client wireless LAN adapter must support Frame Bursting feature too.When multiple wireless clients use Frame Bursting feature, the throughput might not increase Holding 802.11b Association - When this function is enabled, the AirStation requests IEEE802.11b devices to stop communication for a while prior to starting IEEE802.11g communication. If communication speed is decreased, this setting improves total throughput with existing IEEE802.11g and IEEE802.11b standard devices,. The throughput decreases if only IEEE802.11g standard devices exists. DTIM Period - An transmits beacon signals to nearby clients at a preset interval. This parameter sets the beacon transmission interval time (1-255 sec.). Selection of a larger number may conserve energy for the client PC (when client power management is enabled), but may delay wireless communication. The default value of 1 is recommended. ANY Connection - The AirStation can be congured to accept connections from any wireless client using an ESS-ID of ANY. Roaming wireless clients will automatically connect to the nearest access point accepting ANY connections. The only options are to allow or deny connections for these types of clients, thus, wireless networks requiring security should mandate a WEP encryption policy to preserve security if ANY connections are allowed. If Deny is selected under the the ANY Connection, SSID of the AirStation will not be broadcast and users will not be able to connect to the WLA-G54C unless the specic ESS-ID is entered in the client PC.
