[. . . ] Although you can gain a highest data rate, you need to use this function carefully because it occupies large bandwidth and may corrupt the adjacent channels' radio signal. !Note: Super G's channel bonding feature can significantly degrade the performance of neighboring 2. 4GHz WLANs. Moreover, Super G doesn't check to see if 11b or 11g standard-compliant devices are in range before using its non-standard techniques. 802. 11a The 802. 11a mode can support data rate up to 54Mbps (6, 9, 12, 18, 24, 36, 48, 54Mbps). The 802. 11a uses 5-GHz UNII (Unlicensed National Information Infrastructure) frequency band. The 28 AirLive WH-9100-MESH User's Manual use of 5-GHz UNII frequency band provides some distinct advantages over the 2. 4GHz band. In addition to providing a greater amount of bandwidth for transmission, the 5-GHz band has less potential interference because lots of wireless device working in the 2. 4GHz band (Bluetooth, cordless telephone, microwave ovens, and so on) 802. 11a Turbo (This mode is not allowed for outdoor use, so has been removed from wireless mode menu) The 802. 11a Turbo mode can support data rate up to 108Mbps (72, 96, 108 Mbps). 6. 1. 4 Channel Number The channel number is a means of assigning frequencies to a series of access points. If you are using the WH-9100MESH as both an AP and bridge, the channel number set for the AP and the one for bridge should be sufficiently different to avoid interference. Generally, it has been found that the selection channel 4 for bridging and channel 11 for AP gives a good spread at 2. 4GHz band, or one use 2. 4GHz band and another one use 5GHz band. Before you setting the channel, you had better to use the optimal channel function to detect the environment's radio signal and choose the best one for using. Optimal channel If you click on the button "Select the optimal channel", a popup screen will display the choices. After enter this function, the WH-9100MESH detects the environment's radio signal at each channel and show them at this screen. This action does not select the channel for you but shows you what will most probably be channel selected if you leave the following dropdown menu at Yes. 29 AirLive WH-9100-MESH User's Manual 802. 11b, 802. 11g and 802. 11b/g Mixed mode There are 11 (13 for ETSI) channel numbers that may be assigned. Because the 802. 11b signal bandwidth is 22MHz, there are 3 non-overlapping channels for 802. 11b at 2. 4GHz ISM band. To reduce the interference problem, you may be able to establish up to 3 wireless networks at the same area. If you need establish 3 wireless networks, you may assign channel number 1 to the first wireless network. Then the channel 6 will be better for second wireless networks and channel 11 will be the third one. 802. 11g Super The 802. 11g Super mode occupies larger frequency bandwidth. To avoid interfere another wireless network operation, it is fixed at channel 6. 802. 11a and 802. 11a Turbo The frequency band of IEEE 802. 11a will vary according to individual country regulations. The FCC (U. S) has allocated three bands, UNII1(5. 15~5. 25GHz), UNII2(5. 25 ~ 5. 35GHz) and UNII3(5. 725~5. 825GHz). At Taiwan, the 802. 11a device use the 5. 725GHz ~ 5. 875GHz frequency band.

The distribute netmask is 255. 0. 0. 0. 14. 2 Factory Default Click the entry on the left hand navigation panel for System Administration ­ Factory Default to enter this page. The "Restore" button is a fallback troubleshooting function that should only be use to reset system to original settings. 67 AirLive WH-9100-MESH User's Manual 14. 3 Remote Logging Click the entry on the left hand navigation panel for System Administration ­ Remote Logging to enter this page. Remote logging allows you to forward the syslog data from each machine to a central remote logging server. [. . . ]
