QUALITY (reception quality)
Note: the quality index gives an objective picture of the communication quality in order to determine
the practical range limits (depending on the distance from the handset and the nature of the environ-
ment).
In practice, you have to select this function (preferably the averaged measurement), set up a call, and
observe the index value (Q): at a given location, the quality can be considered good if the value dis-
played is equal to or greater than 12 on a stable basis.
A:xx A
Number of CRC errors detected in field
(measured over 120 frames and displayed in hexadecimal)
:0A X:00 Z:00 0
SYN:00 Q/15:16 0
X:xx X
Number of CRC errors detected in field
(measured over 120 frames and displayed in hexadecimal)
0 = mobile free to perform handovers between all system base stations
1 = mobile restricted to using a single base station (no handover)
Z:xx Z
Number of CRC errors detected in field
(measured over 120 frames and displayed in hexadecimal)
0 = rapid measurement
1 = average measurement
Number of synchronization errors reported by the mobile
(measured over 120 frames and displayed in hexadecimal)
transmission quality index (preceded by base station identifier).
The index corresponds to the number of frames received without error
(graded out of 16). There are two display modes:
- rapid measurement (over 16 frames)
- average measurement (over 256 frames)
You can switch between measurement modes with a long press on *.
