It’s most interesting when you put RQI's (Radio Quality Indicators) side by side and see how they influence your throughput. The following table serves to illustrate the range of throughput fluctuations per bandwidth at varying radio conditions:
At extremely low CQI ranges, equivalent to poor radio interface quality, the fluctuations are rather large (10%-30%) representing a very bad perceived experience in terms of throughput. It is therefore suggested that for CQI targets should be set around CQI=10 to guarantee excellent subscriber experience.
