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 3G
Mobile Wireless 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)
◆
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. The extension channel will allow you to get
extra bandwidth. (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. (Default: Enabled)
◆
Decline BA Request — Select to reject peer BA-Request or not. (Default: Disabled)
◆
HT Disallow TKIP — Prevents the use of TKIP data encryption when using 802.11n
high-througput data rates. (Default: Enabled)
