ProSoundTM
The radio may be programmed for ProSound system scan operation for
multi-site applications. ProSound is an enhanced multi-site system
scanning algorithm, compared to Wide Area System Scan. ProSound
provides the radio with the ability to select a new system for the radio to
communicate on, when the selected system drops below a predefined level.
This is accomplished by enabling each radio to analyze the signal quality of
its current control channel and compare it with the signal quality of the
control channel for each site in its adjacency scan list. (The signal quality
metric used for the ProSound algorithm is based on Digital Received Signal
Strength Indicator (RSSI) measurements). When the selected systems
signal quality level degrades below a pre-programmed level, the radio will
begin to look for a better control channel. Once a control channel that
exceeds the pre-programmed parameters is found, the radio will change to
the new system and emit a tone. If the control channel is completely lost
the radio will enter Wide Area System Scanning and search the
programmed adjacent systems until a suitable control channel is found.
ProScanTM
The radio may be programmed for ProScan system scan operation for multi-
site applications depending on the version of radio flash code. (The
ProScan algorithm is available on the Orion Platform with Group 32 or
higher radio flash code). ProScan is an improved multi-site system
scanning algorithm designed to replace the ProSound algorithm. ProScan
provides the radio with the ability to select a new system for the radio to
communicate on, when the selected system drops below a predefined level.
This is accomplished by enabling each radio to analyze the signal quality of
its current control channel and compare it with the signal quality of the
control channel for each site in its adjacency scan list. (The signal quality
metric used for the ProScan algorithm is based on a combination of both
Received Signal Strength Indicator (RSSI) and Control Channel
Verification (CCV) measurements). When the selected systems signal
quality level degrades below a pre-programmed level, the radio will begin
to look for a better control channel. Once a control channel that exceeds the
pre-programmed parameters is found, the radio will change to the new
system and emit a tone. If the control channel is completely lost the radio
will enter Wide Area System Scanning and search the programmed adjacent
systems until a suitable control channel is found.
