Interworking Mission Critical Push-to-Talk (MCPTT) Between Long Term Evolution (LTE) and Land Mobile Radio (LMR)   [open pdf - 964KB]

From the Executive Summary: "Catalyst has proven the technical feasibility of building an Interworking Gateway (IWG) function that provides Mission Critical Push-to-Talk (MCPTT) voice interoperability between Long Term Evolution (LTE) and Land Mobile Radio (LMR) systems and between LMR systems. This analysis has included both Project 25 (P25) and non-P25 radio systems. The project culminated in specifying functionality and quantifying agency cost for a set of specific interworking configurations. The configurations include an Interworking Gateway Adapter that acts as a Bridging Gateway between systems supporting P25 Inter RF Subsystem Interface (ISSI) and P25 or non-P25 LMR systems that do not support ISSI including Digital Mobile Radio (DMR) and Terrestrial Trunked Radio (TETRA)."
