scanning algorithm designed to replace ProSound
scanning. 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 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 ProScan algorithm is based on a combination
of both Received Signal Strength Indicator (RSSI)
and Control Channel Verification (CCV)
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, 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.
