5
Mbps and 74 Mbps respectively and ensures backward compliance for slower 802.11b
devices. (Default: 20/40MHz)
• 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 enables Reverse Direction Grant, the
Multimedia 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.
• Extension Channel – When 20/40MHz channel bandwidth has been set, the extension
channel option will be enabled. The extension channel will allow you to get extra
bandwidth. (Options: 2417MHz/Channel 2, 2457MHz/Channel 10. Default: 2457MHz/
Channel 10.)
• Aggregate MSDU (A-MSDU) – This option enables Mac Service Data Unit (MSDU)
aggregation. (Default: Disable)
• Auto Block ACK – Select to block ACK (Acknowledge Number) or not during data
transferring.
• Decline BA Request – Select to reject peer BA-Request or not.
Other HT Settings
Figure 5-16. HT Physical Mode Settings
• HT TxStream – HT means High Throughput. The number of HT TxStream means how
many antennas will transmit data simultaneously. (Options: 1 or 2. Default: 2)
• HT RxStream – The number of HT RxStream means how many antennas will receive
data simultaneously. (Options: 1 or 2. Default: 2)
Advanced Wireless Settings
The Advanced Setting page allows you to configure the more advanced radio settings,
many of which are enabled by default.
