Taking measurements
Connection quality
In principle, the measurement of the field strength should always be supplemented by a
check of the connection quality. Interference, e.g., through reflection or external systems
that influence the voice quality, can also occur with good reception power.
Therefore, in addition to the reception power, the
is also displayed on the
measuring handset. This indicates the percentage rate of the packages received without
errors in a measurement interval. The optimum value is 100%.
As a rule of thumb, 2% reduction in the frame quality leads to a devaluation by one level
in the quality table illustrated above. Example: the measurement values –60 dBm with a
frame quality of 94% lead to the evaluation "Poor, not suitable", since a quality loss of 6%
leads to a devaluation by three levels.
