FirstNet PTT—the mission-critical-push-to-talk (MCPTT) service launched in 2020—continues to evolve with the development of much-anticipated features like LMR interoperability and broadcast technology that will support one-to-many calls, an AT&T official said during a presentation at the recent APCO 2022 event in Anaheim, Calif.
