(Note: WDS supports wireless g/n modes. The use multiple Access Point will reduces the overall
network throughput to ½ the WRT-893L.
HT Physical Mode: In HT (High Throughput) Physical mode setting allow for control of the 802.11n
wireless environment.
Channel BandWidth:
Set channel width of wireless radio.
20 Channel Width = 20 MHz
20/40 Channel Width = Enables the router to operate on both 20/40 MHz
Guard Interval: Support Short/Long GI, the purpose of the guard interval is to introduce immunity to
propagation delays, echoes and reflections, to which digital data is normally very sensitive.
Long Guard Interval, 800 nsec
Short Guard Interval, 400 nsec
MCS: Fix MCS rate for HT rate (0-15). The Modulation and Coding Scheme (MCS) is a value that
determines the modulation, coding and number of spatial channels.
