For public-safety entities that recently narrowbanded their LMR systems, do you believe they will build a new LMR system in 15 years?

No. Entities will use the LMR systems for mission-critical voice until they reach end of life, but they will switch to LTE at that time.

No. LTE will be the mission-critical-voice technology for public safety long before these LMR systems reach end of life.
28% (33 votes)
Yes. Mission-critical voice for public safety will always run over LMR.
22% (26 votes)
Yes. Mission-critical voice for public safety will migrate to LTE or other broadband technology eventually, but it will be several decades before that happens.

"While satellite coverage may well cover wilderness areas, they won't cover mine shafts, caves, underground parking areas, etc. Sure, DAS will provide for those area with power to run the system - but abandoned mine shafts, etc. will continue to be 'dark holes' in coverage."

Note to self: Stay out of abandoned mine shafts since LTE will not provide coverage. (BTW neither will LMR)

LMR systems are proven and reliable if properly designed, implemented and administered. LTE systems are low powered, too easy to jam, takes way more infrastructure to provide equivalent radio coverage, the subscriber gear is mostly consumer grade, the LTE sites are mostly not hardened and / or not maintained by the operators themselves. Above all, in times of disaster, any system that is shared with the general public will suffer due to loading when needed most. It is understood that some of my arguments can be overcome with time, stellar planning and a ruggedized product basket. The physics of radio however, cannot be overcome. LTE is the perfect data system to augment voice comms but a simple PTT for critical traffic can never be replaced by data. At this stage, LTE is too vulnerable and too young to risk the lives of those who protect ours. Proceed with caution.

No LTE system will ever cover 100% of the need for LMR.

While satellite coverage may well cover wilderness areas, they won't cover mine shafts, caves, underground parking areas, etc. Sure, DAS will provide for those area with power to run the system - but abandoned mine shafts, etc. will continue to be 'dark holes' in coverage. Also, LTE will still be dependent on a network, which will be subject to outages.

Subscriber devices may well end up as a hybrid between LTE and LMR, to meet these challenges.

The same people who were forced to narrowband will wait till the last possible moment to move to LTE. Its the nature of the beast. But by the time that happens we will be moving far beyond LTE...

"The necessity of these technology changes is doubtful but we got them anyway! Who cares what you need.... " Would you prefer to use a conventional repeater system(with none of that modern PL or DPL technology) or a modern digital trunked system? LMR (and all technology) progresses, changes. LTE will replace LMR and something else will come along to replace LTE. Luddites have no place in public safety.

The probability of having to migrate to another LMR system is high, regardless of what happens with LTE. This is because the LMR Vendors have a powerful lobby that can ram in place new technologies to keep LMR sales going and federal dollars flowing. Witness 12.5, 6.25 P25, P25 Phase 2..............The necessity of these technology changes is doubtful but we got them anyway! Who cares what you need.....its what the vendors want you to have that matters!
