Advanced Configuration
Rate Decrement RTX Represents a threshold for percentage of retransmissions, above which the rate can be
Threshold decreased. By default, it is set to 30%. Please note that if the percentage of
retransmissions is between “Rate Increment RTX Threshold” and “Rate Decrement RTX
Threshold” then the current operation rate is maintained.
Chain Balance In the case of MIMO, the difference in SNR between two chains must be less than or equal
Threshold to this threshold for the chains to be considered as “Balanced”. By default, it is set to 15
dB.
:
• This parameter is applicable only for “Auto” stream mode.
• When “Auto” stream mode is configured and if chains are not balanced, then
Single Stream rates are considered.
Rate Back Off Interval The DDRS algorithm constantly attempts higher data rates, when the current rate is stable.
If not successful, it goes back to older stable rate. Before the next attempt, it waits for a
minimum duration. This duration starts with 10 seconds and increases exponentially up to
Rate Back Off Interval and remains at this value. By default, it is set to 300 seconds.
