4.2.6.5.10.3.1Packet Threshold To Test Up Rate
When the number of frames transmitted on the current modulation reaches this
number, the Statistics-Based Rate Control algorithm will test the upper
modulation.
The available range is between 10 and 10000.
The default value is 30.
4.2.6.5.10.3.2Packet No On Upper Rate
This option indicates the number of frames used by the Statistics-Based Rate
Control algorithm to test upper modulations.
The available range is between 1 and 3.
The default value is 3.
4.2.6.5.10.3.3Retries on Lower Modulations
This option enables/disables the retransmissions on lower modulations
mechanism described “Statistics-Based Rate Control Parameters” on page 170.
The default value is Enable.
