CHAPTER 8 AP Client Mode Wireless Configuration

Link Status

◆BW (Channel Bandwidth) — The Wireless-N Access Point/Repeater 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.

◆GI (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.

◆STBC — Indicates if Space Time Block Coding (STBC) is being used. STBC is a MIMO mechanism that allows a unit with only one antenna to leverage multiple antennas on other 802.11n devices to improve performance and range.

◆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))

◆SNR (0/1) — The signal-to-noise ratio value for the MIMO spatial channels 0 and 1.
