Ad Hoc Wireless Mode: Sets Ad Hoc Wireless Protocols, including 802.11 B/G mix, 802.11 B Only and 802.11 G Only. TX Burst: The longest interval between frames is normally one DIFS while frames are transmitted. When this setting is open, the longest interval between frames is one SIFS that means the system is allowed to transmit higher capacity of data in one interval. B/G Protection: 802.11b uses CCK modulation. 802.11g uses OFDM while CCK modulation for 802.11b is compatible. To prevent data collision between two stations with 802.11b and 802.11g within range of the same Access Point, it is necessary to set 11B/G Protection. This setting only functions when 802.11 B/G mix is selected as Wireless Mode. Three setting are available: AUTO, EABLE and DISABLE. This is a mechanism implemented to prevent the “Hidden Node” problem, “Hidden Note” is a situation in which two stations are within range of the same Access Point, but are not within range of each other. Therefore, they are hidden nodes for each other and can not detect each other. This mechanism is a way to prevent data collision when WLAN equipments require transmission. TX Rate: This option adjusts settings of TX Rate according to the setting of “Infrastructure Wireless Mode”. Signal Control: To turn off transferring signals, click on “Turn Off RF” icon on the bottom right corner of the screen. Click “Turn On RF” to transfer signal again.
