Functionalities associated with the new mission-critical push-to-talk (MCPTT) standard for LTE are designed to meet or exceed the capabilities and performance benchmarks for existing land-mobile-radio (LMR) systems, but real-world testing is needed to determine whether MCPTT can overcome some physics limitations that will allow it to meet the needs of first responders, officials said during an IWCE 2016 session on the subject.

On March 11 in Sweden, 3GPP—the standards body that oversees development of the LTE standard—approved the components of MCPTT over LTE as part of LTE Release 13. With the action, vendors now are able to develop products that meet the much-anticipated MCPTT standard.
