MCPTT over LTE and Direct Mode
[Not quite] Mission Critical PTT over LTE is being tested and put into service for live network beta testing. Two things are missing from these trials and tests: a mission-critical or public safety-grade network for the Mission Critical Push-To-Talk application to run over and perhaps more importantly, the way forward to provide direct-mode communications. The UK’s LTE system for public safety to go live in 2020 and replace its existing Tetra system is probably, at the moment, the most robust of the existing LTE networks available.
Recently in France, the European Telecommunications Standards Institute (ETSI) held MCPTT testing sessions and a number of vendors participated to see how well they performed and if they met the 3GPP Release of LTE version 13, which includes specifications for on-network push-to-talk services but does not yet address the issue of direct-mode on and off-network communications. In many instances, direct-mode PTT is as important and in some instances, more important than network-based PTT services. While I recently wrote an Advocate about PTT over LTE and over Land Mobile Radio (LMR) that detailed some of this information, there are a number of things happening in Europe and especially the United Kingdom that could have far reaching effects on how and when PTT services are actually deployed over LTE on and off-network systems.
