Normally, the Max Data Rate should be set to the maximum value. The above example shows this setting MCS15. The default maximum is 54 MBits/s. However, under poor operating conditions, reliability may improve if the Max Data Rate is reduced.

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 0. Throughput in 802.11n wide mode is approximately twice that of 802.11n

current operating conditions. 

The system attempts to use a 400 microsecond Guard Interval, but will fall back to an 800 microsecond Guard Interval if excessive data corruption is detected. The radio will periodically attempt to resume using a 400 microsecond Guard Interval as conditions improve. A 400 microsecond Guard Interval results in about 11% more throughput than using a 800 microsecond guard interval. The user has no control of the Guard Interval. As seen in the table above, absolutely best throughput requires 802.11n wide mode, more than one antenna, and a RF environment capable of supporting a 400 microsecond Guard Interval.

Max Basic Rate

 In addition to the Data Rate setting which controls generic data traffic, the Basic Rate setting adjusts the rate at which control packets such as Beacons and ACKs are sent at as well as packets that need to go to the whole network such as Broadcasts. Because these packets are intended for the whole network, the Max Basic Rate setting of the Master is advertised to each of the radios in the network through Beacons. Each radio, other than the Master, then inherits the Max Basic Rate setting of the Master. Therefore the setting only needs to be made in the Master radio. The setting in each of the other radios is disregarded.
