Proportional IR Factor Sets up the percentage for the Proportional IR Factor mechanism
usage. The higher the value, the more weigth the PIF algorithm has in
setting up the rates.
Valid values range from 0 to 100 (%).
The default value is 0 (%) (PIF is disabled).
Update Period Sets up the duration (in minutes) between the periodical computation
of MIR/CIR values used for uplink/downlink.
Valid values range from 1 to 30 (minutes).
The default value is 5 (minutes).
Threshold Percentage The percentage of the average rate variation compared to the
configured rate that, when exceeded, triggers (along with the
Proportional IR Threshold Rate) the used rate adjustment.
Valid values range from 0 to 100 (%).
The default value is 20 (%).
Threshold Rate If the transmission modulation falls below this level, and the
Proportional IR Threshold Percentage conditions are met (see
above), the rate adjustment is triggered.
Valid values range from 1 to 8 (modulation).
The default value is 5.
