RSSI Good Threshold Use the UP/DOWN arrows to make your selection or enter a value
directly. In the RSSI sampling scheme, RSSI values are separated into
four levels: poor, acceptable, good and excellent. This value specifies
the acceptable/good boundary. Domain {L: 00 <= L <= FF}.
RSSI Excellent Threshold Use the UP/DOWN arrows to make your selection or enter a value
directly. In the RSSI sampling scheme, RSSI values are separated into
four levels: poor, acceptable, good and excellent. This value specifies
the good/excellent boundary. Domain {L: 00 <= L <= FF}.
VC RSSI Accpt Threshold
(Voice Channel RSSI Acceptable
Threshold)
While in a voice call, RSSI samples will be compared against the Voice
Channel RSSI Acceptable Threshold. If samples fall below this
threshold, the radio will initiate an attempt at site switching, causing
an interruption in the voice call. Valid RSSI values range from 1 to FF.
Selecting Disabled will set the threshold to 0, disabling voice channel
RSSI site switching.
The factory default is Disabled.
Special Note On RSSI
Threshold Constant
Settings
The default values for the RSSI (received signal strength indication)
threshold constants programmed in your radio may not be optimal for
your system. These values are critical for proper site switching. Please
review the following information to set the RSSI threshold constants
for your SmartZone system configuration and desired site switching
performance.
RSSI ranking levels are as follows:
Acceptable Threshold
The acceptable Threshold sets the minimum audio quality level. A
signal with an RSSI value lower than the acceptable threshold will
switch to any site with a better audio quality rating.
Increase this level to always require a better signal. Decrease this
threshold level to prevent switching back and forth between two
weak sites. POOR designates unacceptable or unintelligible audio
quality. ACCEPTABLE designates intelligible, but undesirable, audio
quality. If the signal is above the acceptable threshold level, the radio
will site switch if an excellent site is found. Otherwise, the radio will
remain at the current site because allowing changes to sites with
similar signal levels can cause the radio to switch back and forth,
causing undesirable delays in speech.
Good Threshold
Sets the maximum signal level/audio quality that will site switch.
Radios receiving stronger signals will not site switch. GOOD
designates audio quality that is good enough that no site switching is
necessary. This level of audio quality is also used as a buffer to prevent
switching back and forth between two sites with similar signal level.
Excellent
Sets the desired Audio quality. The radio receiving an ACCEPTABLE
signal will only switch to a site with excellent audio quality.
EXCELLENT designates excellent audio quality or the desired audio
