[. . . ] Disabling the SSID broadcast increases security of the network because wireless clients need to already know the SSID before attempting to connect. When set to disable, the Network Name SSID, and SSID1 are automatically set to "Hide. " (Default: Enabled) AP Isolation -- The Mini 3G Broadband Router will isolate communincation between all clients in order to protect them. (Default: Disabled) MBSSID AP Isolation -- The Mini 3G Broadband Router will isolate wireless clients from different SSID. BSSID -- The identifier (MAC address) of the Mini 3G Broadband Router in the Basic Service Set (BSS) network. Frequency (Channel) -- The radio channel that the Mini 3G Broadband Router uses to communicate with wireless clients. When multiple access points are deployed in the same area, set the channel on neighboring access points at least five channels apart to avoid interference with each other. For example, you can deploy up to three access points in the same area using channels 1, 6, 11. Note that wireless clients automatically set the channel to the same as that used by the Mini 3G Broadband Router to which it is linked. Selecting Auto Select enables the Mini 3G Broadband Router to automatically select an unoccupied radio channel. (Default: Channel 11) ­ 74 ­ CHAPTER 7 | Wireless Configuration Basic Settings HT PHYSICAL MODE The HT Physical Mode section on the Wireless Settings Advanced page SETTINGS includes additional parameters for 802. 11n operation. Figure 39: HT Physical Mode Settings The following items are displayed in this section on this page: HT Channel Bandwidth -- The Mini 3G Broadband Router provides a channel bandwidth of 40 MHz by default giving an 802. 11g connection speed of 108 Mbps (sometimes referred to as Turbo Mode) and a 802. 11n connection speed of up to 150 Mbps. Setting the HT Channel Bandwidth to 20 MHz slows connection speed for 802. 11g and 802. 11n to 54 Mbps and 74 Mbps respectively and ensures backward compliance for slower 802. 11b devices. (Default: 20MHz) Guard Interval -- The guard interval between symbols helps receivers overcome the effects of multipath delays. When you add a guard time, the back portion of useful signal time is copied and appended to the front. (Default: Auto) MCS -- The Modulation and Coding Scheme (MCS) is a value that determines the modulation, coding and number of spatial channels. (Options: value [range] = 0~7 (1 Tx Stream), 8~15 (2 TxStream), 32 and auto (33). Default: auto) Reverse Direction Grant (RDG) -- When Reverse Direction Grant is enabled, the Mini 3G Broadband Router can reduce the transmitted data packet collision by using the reverse direction protocol. During TXOP (Transmission Opportunity) period, the receiver could use remaining transmission time to transmit data to a sender. The RDG improves transmission performance and scalability in a wireless environment. (Default: Enabled) ­ 75 ­ CHAPTER 7 | Wireless Configuration Advanced Settings Space Time Block Coding (STBC) -- A mechanism that allows a unit with only one antenna to leverage multiple antennas on other 802. 11n devices to improve performance and range. (Default: Enabled) Extension Channel -- When 20/40MHz channel bandwidth has been set, the extension channel option will be enabled. (Default: AutoSelect. ) Aggregate MSDU (A-MSDU) -- This option enables Mac Service Data Unit (MSDU) aggregation. (Default: Disabled) Auto Block ACK -- Select to block ACK (Acknowledge Number) or not during data transferring.
