Description
Max Data Rate
The maximum data rate for the RLX2-IHNF radio is specified in terms
of a Modulation and Coding Scheme (MCS) index value. This
specification is unique to IEEE 802.11n devices. The actual maximum
data rate depends on several factors as shown in the following table:
802.11n mode,
MBits/sec
802.11n wide mode,

Only MCS rates from 0 through 7 are available with one antenna,
which is the default configuration. To select MCS rates of 8 and above,
configure the Active Antennas to be A,C or A,B,C. (See Active
Antennas below.)
The maximum throughput also depends on the 802.11n Mode as
configured in the Radio Network Settings section of the main
webpage. See section 6.2. Throughput in 802.11n wide mode is
approximately twice that of 802.11n mode.
The radio will automatically select the Guard Interval (GI) based on
