Mission-critical PTT will be included in Long Term Evolution (LTE) Release 13, which was finalized at the meetings, said Dean Prochaska, director of standards for the First Responder Network Authority (FirstNet), who attended the meetings.
“This is a big deal,” Prochaska said. “Mission-critical PTT will have the features and functionality equivalent to LMR systems today.”
Commercially available products generally follow about two years after a standard is finalized.
Work on LTE Release 14, which could define mission-critical video and data, is underway. Release 14 has a targeted completion date of June 2017.
Separately, Yannick Lair with LG Electronics was elected the new chairman of SA6 in February. SA6 is the working group within 3GPP that defines specifications for critical communications.
