Single-Frequency P25 Trunked Systems

Single-frequency P25 systems are almost idfentical to standard P25 systems, except they only have one site per system and the system can use a P25 network address. Here is a conceptual layout diagram of a single-frequency P25 system (click here for a legend of the diagram).
