System Configuration
• 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
wireless AP/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
• 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)
