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
