LMR systems have evolved to their present configuration over the last 70 years, ever changing with new technology to adapt to the needs of first responders. With public safety broadband solutions now here and Mission Critical Push to Talk being deployed, it is understood that these networks may ultimately replace land mobile radio networks as the primary means of voice communications for first responders. However, nobody can say for certain exactly how the convergence of LMR and public safety broadband will take place, or when it will happen. This presentation will review the current state of each technology platform, how the platforms are being integrated today, and what barriers must be overcome to support adoption.
