3GPP approves standard for mission-critical PTT (MCPTT) over LTE in Release 13

Mission-critical push-to-talk (MCPTT) functionality is now part of the LTE standard in Release 13, which was “frozen” by the 3GPP standards body last week in Sweden. As a result, MCPTT-capable equipment should be available for FirstNet when Release 13 is scheduled to be implemented as early as 2018.
