Mission Critical Push-to-Talk (MCPTT) is an international 3GPP standard that allows public safety agencies to use broadband cellular networks (4G/LTE and 5G) with the same one-button Push-to-Talk feature as their traditional Land Mobile Radios (LMR).
In plain English, MCPTT makes a smartphone as quick and easy to use as a one-button PTT LMR handset. What makes MCPTT so different is that it uses the high-speed data capacity of cellular networks to enable live video streaming, file sharing, and real-time location tracking, capabilities that traditional voice-only radio systems simply cannot match.
