ProSound
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 compares 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 (DRSSI) measurements). When
the selected system degrades to 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, t6he 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.
ProScan
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 LPE-200
Platform with Release R8A or higher radio flash
code). ProScan is an improved multi-site system
